Tricuspid valve disorders (TVDs) have historically been underrecognized by clinicians. However, recent years have seen increasing awareness of their clinical impact. This mini-review aims to briefly highlight some questions regarding TVDs, such as Review of tricuspid valve disorders, Decoding its trends, The gender and racial divide, Breaking barriers, Where you live matters, Surgery vs. minimally invasive options, Bridging the gap, and the underappreciated significance of TVDs and why they’re becoming a growing concern in the U.S. There is a significant change in perception of the tricuspid valve—from being the “forgotten valve” to being an important area of focus in cardiology as well as clinical medicine in general. With the aid of advanced imaging methods like echocardiography, CT, and MRI that show a clear and three-dimensional view of the tricuspid valve, there is a better understanding of both the prevalence and diagnostic precision of TVDs. Advancements involving more efficient and optimally timed treatment strategies are also occurring. Although medical and surgical approaches are still in use, developments such as transcatheter tricuspid valve interventions (TTVIs) are promising, particularly for high-risk patients with minimal improvement with surgical treatment. TVDs, especially tricuspid regurgitation, have gained widespread attention in the medical and research community, resulting in improved and evolving diagnostic and therapeutic progress to improve patient outcomes.

We report the case of a 58-year-old woman who developed typical chest pain following intravaginal administration of misoprostol, used routinely as a premedication before a hysteroscopy. Misoprostol is a synthetic prostaglandin E1 analogue widely employed for cervical softening and the medical management of an incomplete abortion, and is generally considered safe. The chest pain was accompanied by transient, severe ST-segment elevation (up to 6 mm) in the inferior and inferolateral electrocardiogram (ECG) leads, which resolved promptly after sublingual nitrate administration. A hyperventilation test (5 minutes at 30 breaths per minute) demonstrated a paradoxical reduction in peak diastolic flow velocity in the mid-to-distal left anterior descending coronary artery. Invasive coronary angiography showed smooth, angiographically normal coronary arteries, but provocation with intracoronary acetylcholine induced complete vasospasm of the left circumflex artery. This case underscores the importance of recognizing vasospastic angina even in non-cardiology settings. It highlights the value of targeted noninvasive and invasive diagnostic testing to confirm this often overlooked, underdiagnosed, and undertreated condition.

Resistant Kawasaki has been associated with the aggressive development of large coronary aneurysms, despite prompt treatment. In this paper, we present an infant who presented with resistant Kawasaki. Although initially he seemed to defervesce after the initial administration of intravenous immunoglobulin, he developed a new onset of fever, requiring a repeat dose of immunoglobulin. Coronary aneurysms developed rapidly, necessitating a second dose of immunoglobulins and second-line treatments such as anakinra and infliximab. High titers of COVID-19 antibodies have been a confounding factor in the management of that child, as the alternative diagnosis of multisystem inflammatory syndrome in children (MIS-C) was considered. Finally, the clinical and laboratory values were more in keeping with MIS-C.

Phrenic nerve palsy (PNP) is a recognized complication of cryoballoon ablation (CBA) for atrial fibrillation (AF), particularly during the ablation of the right superior pulmonary vein (RSPV). We report the case of an 80-year-old female with a history of hypertension, who was admitted for CBA of paroxysmal AF. Despite optimal medical treatment with amiodarone, the patient experienced recurrent episodes of AF, prompting the decision to proceed with CBA. During the procedure, while isolating the RSPV, diaphragmatic movement was significantly weakened after 92 seconds of cryoablation at a temperature of –52°C. Immediate cessation of the procedure and intravenous methylprednisolone were administered, resulting in partial recovery of diaphragmatic movement. However, when the procedure resumed, diaphragmatic movement once again diminished, and despite further steroid treatment, the movement did not recover by discharge. The patient remained asymptomatic with stable oxygen saturation, and no respiratory distress was noted. At a six-month follow-up, the patient reported no symptoms of chest tightness or shortness of breath, and her general condition remained stable, although diaphragmatic movement had not fully recovered, indicating partial functional compensation. This case underscores the importance of continuous phrenic nerve monitoring during CBA, early detection of complications, and appropriate management to prevent irreversible injury, highlighting the need for careful procedural planning and postoperative follow-up in elderly patients with comorbidities.

Aim:
To assess the incidence and predictors of hypertensive response to exercise (HRE) of blood pressure during stress echocardiography (SE) with physical exercise in patients with known or probable coronary artery disease, and the effect of HRE on the results of the five-step SE.
Methods:
The single-center study included 193 patients who underwent ABCDE-SE. The incidence of HRE, predictors of its occurrence, and the relationship with positive results of the study protocol steps were investigated.
Results:
HRE was detected in 36.3% of patients (70 patients) and occurred more frequently during the bicycle ergometer test (p = 0.027). Patients with HRE had a significantly lower peak wall motion score index (p = 0.050) and achieved a preload ratio (p = 0.035), as well as higher left anterior descending coronary artery (LAD) blood flow velocity at rest and during exercise (p = 0.009 and p = 0.008, respectively). They also showed higher peak left ventricular (LV) contractile reserve and force (p = 0.002 and p = 0.006). Reduced contractile reserve was less common in patients with HRE (p = 0.013). Predictors related to HRE development were identified: history of LAD stenting, thickness of the LV posterior wall, LAD blood flow velocity, and normal LV force at rest (p = 0.006, p = 0.022, p = 0.004, and p = 0.003, respectively), as well as a positive step C (p = 0.005).
Conclusions:
The prevalence of HRE, its predictors, and the relationship with the ABCDE-SE results were revealed. The correlation between blood pressure response to exercise and SE steps, as well as its prognostic significance, needs further study.

We present the electrocardiogram (ECG) of an elderly woman with Mobitz II atrioventricular (AV) block, left bundle branch block (LBBB), and ventricular ectopic activity. At first glance, the ECG may give the misleading impression of Wenckebach periodicity and raise the suspicion of intermittent left anterior fascicular block (LAFB) and left posterior fascicular block (LPFB), suggesting an apparent alternating conduction block in the main divisions of the LBB. This intriguing appearance prompted us to present the case.

Our cells and, therefore, our organism, need energy to function at their best, which is mainly produced by mitochondria. These intracellular organelles generate energy from food macromolecules across the Krebs cycle by oxidative phosphorylation. Energy is developed by converting adenosine triphosphate (ATP) to adenosine diphosphate (ADP). It is essential, for adequate mitochondrial energy production in the form of ATP, to have the right number of well-functioning mitochondria and the right amount of oxygen (O2) available. Unfortunately, the aging process and the chronic diseases that arise over the years are associated with a reduction in the number of mitochondria and their insufficient functioning. Among the chronic diseases related to significant damage of the arteries with a reduction in the supply of O2, there is atherosclerosis, where the process of atherothrombosis occurs. To keep our organs well-functioning despite aging, we must therefore protect our mitochondria and arteries. This can be achieved by intervening early in prevention with a lifestyle correction and diet integration with effective natural substances or, in some cases, with drugs. Among the many natural substances that have good scientific support, we have chosen four that have demonstrated benefits in the absence of side effects and that we know best: quercetin and pyrroloquinoline quinone to stimulate mitochondrial biogenesis and mitophagy, while L-arginine and nattokinase to protect the arteries from atherothrombosis.

Scientific evidence seems to indicate that, in males, intense and prolonged endurance sport can favor the onset of atrial fibrillation. A plausible explanation may be the impact that intense endurance sports produce on the three vertices of Coumel’s triangle. However, genetics is probably also involved in translating this impact into an arrhythmic phenotype. On a management level, the first task of the cardiologist is to exclude the presence of structural heart disease, channelopathy, endocrine and/or electrolyte disorders, and substance use. As for the treatment of arrhythmia, the “CARE” paradigm proposed by the latest ESC guidelines should probably be accompanied by detraining, although this suggestion is often rejected by the athlete. Anticoagulant therapy, where indicated, must take into account the risk of trauma that the sport entails, even if the particular pharmacodynamics/pharmacokinetics of DOACs should allow training/competition to take place when the anticoagulant effect of the previous administration has completely or almost completely worn off.

We report a rare case of non-ischemic cardiomyopathy in a 62-year-old female with mucous membrane pemphigoid following rituximab therapy. The patient presented with dyspnea and chest pain, and cardiac evaluation-including transthoracic echocardiogram and nuclear medicine stress testing-revealed left ventricular dysfunction without evidence of ischemia. Given the temporal association and absence of other etiologies, rituximab was suspected as the causative agent. This case emphasizes the importance of recognizing the potential cardiotoxic effects of biological agents used in autoimmune disease management and supports the consideration of cardiac surveillance in at-risk patients receiving rituximab.

Fungal endocarditis (FE) is still an uncommon but devastating infection, especially when immunosuppression, prosthetic valve surgery, or prolonged health care is involved. Although being only responsible for 1–6% of infective endocarditis cases, the mortality rate is higher than 40–60% due to the time lag from diagnosis and therapeutic complexity. Etiology is led by Candida species, especially Candida albicans, followed by Aspergillus, and new pathogens like multidrug-resistant Candida auris are also seen. Non-C. albicans and the biofilm-forming species also add more complexity to the manageability. Diagnosis is challenging due to the high percentage of culture-negative cases, particularly for molds, requiring sophisticated investigations such as fungal biomarkers (β-D-glucan, galactomannan), molecular tests, and imaging studies such as 18F-FDG PET/CT (fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography). Early transesophageal echocardiography is crucial in the diagnosis of vegetations, whereas histopathology of resected non-cardiac tissue offers a definitive diagnosis. Treatment requires aggressive antifungal therapy, echinocandins, amphotericin B, or azoles, in conjunction with urgent valve surgery to reduce embolic risk and enhance survival. However, drug resistance, biofilm resistance, and patient comorbidities counteract the efficacy. Novel treatments such as rezafungin and ibrexafungerp are promising but have limited clinical hands-on evidence. Risk factors of immunosuppression, indwelling devices, and IV drug use imply a need for increased clinical suspicion in high-risk groups. Although there have been minor improvements in FE survival, the grim situation of FE persists, highlighting the importance of a multidisciplinary approach, early diagnosis, and tailored antifungal therapy to control this deadly infection.

We aim to describe a unique case of a desmoplakin gene mutation with refractory ventricular arrhythmia and cardiomyopathy. We describe a 29-year-old man hospitalized for chest pain and cardiomyopathy, who subsequently developed ventricular arrhythmia that was refractory to multiple antiarrhythmic agents, ablation, immunotherapy, and sympathectomy. Diagnostic studies included coronary catheterization, cardiac MRI, and endomyocardial biopsy. He underwent placement of an Impella 5.5 temporary mechanical support device for multi-organ failure; eventually requiring a Heartmate 3 left ventricular assist device. This report details how cardiac MRI, endomyocardial biopsy, and genetic testing are crucial diagnostic modalities when assessing patients with refractory arrhythmias or myocarditis. Pathogenic variants in the desmoplakin gene can be associated with significant morbidity in patients and require multidisciplinary care from cardiology, electrophysiology, advanced heart failure, and cardiac surgery. Arrhythmogenic cardiomyopathies should be considered for patients suffering repeated episodes of myocarditis or refractory ventricular arrhythmias. We utilized various criteria of functional, electrocardiographic, arrhythmic, tissue characterization, and genetic findings to establish the diagnosis of arrhythmogenic cardiomyopathy, which will be discussed later in this paper.

We report the case of a 58-year-old patient with chronic ischemic syndrome who underwent dipyridamole stress echocardiography for the evaluation of chest pain. The stress test was negative with normal coronary flow velocity reserve, preserved chronotropic competence, and no inducible wall motion abnormalities. However, upon administration of aminophylline at the end of the test, the patient developed acute chest pain, ST-segment elevation, and severe apical wall motion abnormalities. These findings resolved with intravenous nitrates. Subsequent coronary angiography revealed a significant vasospastic stenosis in the left anterior descending artery superimposed on a mild organic stenosis of around 50% after intracoronary nitrates. The coronary stenosis was successfully treated with a drug-eluting stent. This case highlights the potential for vasospastic angina to be unmasked following vasodilator reversal, even after a negative stress echocardiography.

Peripartum cardiomyopathy (PPCM) is a rare condition characterized by heart failure secondary to left ventricular systolic dysfunction, occurring in women during the last trimester of pregnancy or within five months postpartum. Despite advancements in research, PPCM remains a life-threatening disorder associated with significant maternal morbidity and mortality. The primary clinical manifestations of PPCM result from heart failure due to impaired left ventricular systolic function. This article reviews the epidemiology, etiology, diagnostic criteria, management strategies, and outcomes of PPCM. Additionally, we present a case of a 34-year-old woman with PPCM who achieved full recovery within nine months, underscoring the importance of early recognition, prompt treatment, standardized medication, and regular follow-up.

This article belongs to the special issue Cardiovascular Risk for Mothers and Offspring Resulting from Complicated Pregnancy
Aim:
Coronary heart disease (CHD) has been the leading cause of death worldwide for several decades. Non-alcoholic fatty liver disease (NAFLD), the most common liver pathology, is considered a risk factor (RF) for the development of CHD and a predictor of an unfavourable prognosis. Our study aimed to compare cardiometabolic parameters in patients with CHD with and without NAFLD.
Methods:
The study prospectively included 85 patients with CHD, 61 with NAFLD (group I) and 24 without NAFLD (group II). In both groups, a comparative analysis of RF, anthropometric parameters, lipidogram, glycemic profile, brachiocephalic arteries (BCA) ultrasound (USD), and heart structural and geometric parameters according to echocardiography (EchoCG) and coronary calcium (CC) parameters was performed.
Results:
Patients with CHD and NAFLD had statistically significantly higher levels of total cholesterol, very low-density lipoproteins, triglycerides, insulin, heart structural parameters, and CC.
Conclusions:
Thus, the relationship between NAFLD and CHD is two-way, and liver diseases can exacerbate the course of cardiovascular diseases (CVD).

Cardiac papillary fibroelastoma (CPF) is a rare, benign cardiac tumor with a significant risk for embolic complications, most notably ischemic stroke. This paper presents a case of a 54-year-old woman with cryptogenic stroke ultimately attributed to a CPF on the aortic valve, discovered via transesophageal echocardiography (TEE) after an initial unremarkable transthoracic study. Following diagnosis, the patient was treated with anticoagulation and scheduled for surgical excision. Although often asymptomatic, CPF can present with life-threatening embolic events, underscoring the importance of timely diagnosis through high-resolution imaging, particularly TEE. Surgical excision remains the definitive treatment in symptomatic or high-risk cases, but management of incidental, asymptomatic tumors remains controversial due to the absence of formal guidelines. This paper emphasizes the need for heightened clinical suspicion of CPF in cryptogenic stroke and advocates for individualized treatment approaches based on tumor characteristics and embolic risk.

Aim:
The efficacy of composite valve graft (CVG) versus stentless aortic root replacement (SARR) in patients with aortic valve and root pathologies remains a subject of debate. This study aims to analyze the in-hospital outcomes and long-term survival of these two surgical approaches.
Methods:
A retrospective analysis was conducted on 594 patients who underwent ARR between July 2003 and December 2023. Of these, 346 received a stentless aortic root and 248 CVG (100 biological and 148 mechanical). Propensity score matching (PSM) was utilized to create well-balanced cohorts based on preoperative demographics and intraoperative characteristics. Univariable and multivariable regression analyses were performed to evaluate in-hospital mortality and long-term survival rates. Kaplan-Meier curves were constructed to visualize survival outcomes.
Results:
After PSM, 212 patients in each group were well-balanced in terms of baseline characteristics. The analysis of in-hospital outcomes revealed no significant differences between the SARR and CVG groups for key outcomes except neurological complications that were consistently higher in the CVG group, with a significant difference observed in both unmatched (8.4% vs. 4.9%, P = 0.014) and matched cohorts (8.5% vs. 4.3%, P = 0.022). Long-term survival analysis in the matched cohorts demonstrated a statistically significant survival advantage for the SARR group, with a 20-year survival rate of 54% compared to 47% for the CVG group (log-rank P value of 0.047). Further analysis by specific graft type within the matched groups suggested that xenografts might offer a significant survival advantage (log-rank P value of 0.009).
Conclusions:
While SARR and CVG provided similar in-hospital outcomes, SARR, particularly xenografts, demonstrated a significant long-term survival advantage. Xenografts may be a preferable option for patients, especially those with longer life expectancies, due to their durability and reduced need for anticoagulation.
Aim:
The efficacy of composite valve graft (CVG) versus stentless aortic root replacement (SARR) in patients with aortic valve and root pathologies remains a subject of debate. This study aims to analyze the in-hospital outcomes and long-term survival of these two surgical approaches.
Methods:
A retrospective analysis was conducted on 594 patients who underwent ARR between July 2003 and December 2023. Of these, 346 received a stentless aortic root and 248 CVG (100 biological and 148 mechanical). Propensity score matching (PSM) was utilized to create well-balanced cohorts based on preoperative demographics and intraoperative characteristics. Univariable and multivariable regression analyses were performed to evaluate in-hospital mortality and long-term survival rates. Kaplan-Meier curves were constructed to visualize survival outcomes.
Results:
After PSM, 212 patients in each group were well-balanced in terms of baseline characteristics. The analysis of in-hospital outcomes revealed no significant differences between the SARR and CVG groups for key outcomes except neurological complications that were consistently higher in the CVG group, with a significant difference observed in both unmatched (8.4% vs. 4.9%, P = 0.014) and matched cohorts (8.5% vs. 4.3%, P = 0.022).

Aim:
Atherosclerosis and diabetes mellitus (DM) often lead to severe conditions, such as acute ischemic stroke (AIS), cardiovascular disease (CVD), and chronic kidney disease (CKD). Some cancers are also associated with atherosclerosis. Therefore, identifying novel autoantibody biomarkers associated with atherosclerosis-related conditions is crucial for improving early diagnosis and risk assessment.
Methods:
We used an array of 9,480 proteins to detect IgG antibodies in the serum of patients with atherosclerosis. Following this screening, we quantified the antibody levels using an amplified luminescent proximity homogeneous assay-linked immunosorbent assay (AlphaLISA) with recombinant antigen proteins.
Results:
Ubiquitin conjugating enzyme E2 E3 (UBE2E3) was identified as a candidate antigen recognized by IgG antibodies in the sera of individuals diagnosed with atherosclerosis. Compared with healthy donors, significantly higher serum antibody levels against UBE2E3 were found in patients with AIS, DM, CVD, CKD, esophageal cancer (EC), and gastric cancer (GC), but not in those with colorectal cancer (CRC). Receiver operating characteristic (ROC) analysis revealed that the higher areas under the ROC curves for anti-UBE2E3 antibodies were observed in DM- or nephrosclerosis-associated CKD than in the others. Spearman’s correlation analysis revealed that serum anti-UBE2E3 antibody (s-UBE2E3-Ab) levels were associated with the plaque score, maximum intima-media thickness, and cardio-ankle vascular index, which are typical indices of atherosclerosis and stenosis. In the survival analysis of GC and CRC, patients who were s-UBE2E3-Ab-positive had significantly poorer prognoses than patients who were s-UBE2E3-Ab-negative. The difference became more prominent when s-UBE2E3-Abs were combined with anti-differential screening-selected gene aberrant in neuroblastoma antibody (DAN-Ab) or sclerostin domain-containing protein 1 (SOSTDC1), which are bone morphogenetic protein (BMP) antagonists.
Conclusions:
The s-UBE2E3-Ab marker is highly associated with atherosclerosis-related diseases, such as AIS, CVD, DM, CKD, and digestive tract cancers, suggesting the involvement of BMP signals.

Analysis of intraventricular pressure gradients has gained interest due to the recent development of a new method of image analysis based on cardiac magnetic resonance feature tracking or echocardiographic speckle tracking. Currently, images acquired from routinely performed cardiac magnetic resonance or echocardiography can be analyzed, and the left ventricular hemodynamic forces (HDF) curves generated and displayed for measurements. This modality has been applied in clinical scenarios and normal reference values are available. However, different parameters have been derived in the available studies on HDF, and there is no standardization on which parameters should be reported. In this short review, we describe how to assess HDF and discuss the different parameters that can be derived from the HDF curves.

An electrocardiogram (ECG) is a vital diagnostic tool used during cardiac imaging stress testing to evaluate the heart’s electrical activity under stress conditions. This combination of ECG and stress imaging testing provides comprehensive insights into cardiac function, particularly in detecting coronary artery disease (CAD) and assessing overall heart health. An ECG continuously monitors the heart’s electrical signals, capturing data on heart rate, rhythm, and electrical conduction patterns. The value of the ECG in this context lies in its ability to detect ischemic changes, which occur when there is insufficient blood flow to the heart muscle due to narrowed or blocked coronary arteries, but also for coronary vasospasm or coronary microvascular disease. Specific ECG changes, such as ST-segment depression or elevation, and the appearance of arrhythmias, can indicate myocardial ischemia. These findings, when correlated with symptoms like chest pain or shortness of breath during the test, may provide strong evidence for CAD even in the absence of diagnostic abnormality of cardiac imaging with regional wall motion or perfusion changes. Additionally, the ECG helps identify other conditions that may manifest under stress, such as arrhythmias or conduction abnormalities, which might not be apparent at rest. The ECG’s role extends beyond diagnosis. It helps stratify patients based on their risk of adverse cardiac events. For example, an abnormal ECG during a negative cardiac stress imaging test can suggest an increased likelihood of coronary calcification or abnormal coronary flow reserve and increased risk in the long term for cardiac events. In summary, the ECG is a valuable component of cardiac imaging stress testing. It provides real-time, non-invasive monitoring of the heart’s electrical activity under stress, aiding in the diagnosis and risk assessment of CAD and other cardiac conditions. This enhances patient management by guiding treatment decisions and preventive strategies.

Tuberculosis (TB) continues to pose a significant public health burden in endemic regions, remaining a leading cause of morbidity and mortality. Although TB is associated with a range of complications, the occurrence of intracardiac thrombus is an exceptionally rare manifestation. We report the case of a 62-year-old male with active pulmonary TB, who had been on anti-tubercular therapy for one month and presented with recurrent syncope and exertional dyspnea. Transthoracic 2D echocardiography revealed a large, mobile thrombus in the left ventricular apex. Evaluation for underlying hypercoagulable states was unremarkable. The patient was managed with anticoagulation therapy in conjunction with ongoing anti-tubercular treatment. This case underscores the importance of clinical vigilance for rare thrombotic complications in TB to facilitate timely diagnosis and appropriate management.
