Article Abstract
Purpose: To investigate the pathologic substrates of sudden death in young competitive athletes.
Patients And Methods: Twenty-two cases of sudden death in young competitive athletes occurring in the Veneto region (northern Italy) in the period January 1979 to December 1989 were studied by postmortem examination. The athletes included 19 males and three females, ranging in age from 11 to 35 years (mean, 23 years).
Results: In 18 cases, sudden death occurred during (16 cases) or immediately after (two cases) a competitive sport activity. In 10 subjects, sudden death was apparently the first sign of disease. Postmortem examination disclosed that this fatality was due to arrhythmic cardiac arrest in 17 cases; among these, right ventricular cardiomyopathy, also known as "right ventricular dysplasia," was the most frequently encountered cardiovascular disease (six cases), followed by atherosclerotic coronary artery disease (four cases), conduction system pathology (three cases), anomalous origin of right coronary artery from the wrong aortic sinus (two cases), and mitral valve prolapse (two cases). In two athletes, the abrupt lethal complication was "mechanical" and consisted of pulmonary embolism and rupture of the aorta; in three athletes, death was due to a cerebral cause. All athletes with right ventricular cardiomyopathy died during effort, and most had a history of palpitations and/or syncope. Whenever available, electrocardiographic (ECG) tracings showed inverted T waves in precordial leads and/or left bundle branch block ventricular arrhythmias.
Conclusions: Clinicopathologic correlations indicate that in the Veneto region of Italy, right ventricular cardiomyopathy is not so rare among the cardiovascular diseases associated with the risk of arrhythmic cardiac arrest, and seems to account for the majority of cases of sudden death in young athletes; this disorder can be suspected during life on the basis of prodromal symptoms and ECG signs.

Purpose Of Review: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a devastating heritable channelopathy that can lead to sudden cardiac death in children and young adults. This review aims to explore genetics, the cardiac and extracardiac manifestations of mutations associated with CPVT, and the challenges involved with managing phenotypically variable variants.
Recent Findings: The understanding of the genetics and mechanisms of CPVT continues to grow with recent discoveries including alternative splicing of cardiac TRDN and calmodulin gene variants.

Objective: Paliperidone palmitate is a second-generation antipsychotic that has undergone extensive investigation in clinical trials. However, real-world studies assessing its safety in large populations are lacking. As such, this study aimed to comprehensively evaluate real-world adverse drug events (ADEs) linked to paliperidone palmitate by employing data mining techniques on the U.

Studies have demonstrated overall prognostic benefits of ICD implantation in patients at increased risk of sudden cardiac death. However, results are inconsistent in certain subgroups. This study aims to evaluate the prognostic implications of comorbidities on ICD outcomes and compare trends in patient selection and outcomes over a decade-long inclusion period.

Rationale: Cardiac papillary fibroelastoma (CPF) is a rare cardiac tumor that can lead to severe and potentially fatal complications such as stroke, myocardial infarction, and sudden cardiac death. The rarity of CPF makes it challenging for clinicians to diagnose and treat, highlighting the importance of timely and accurate diagnosis to prevent catastrophic outcomes. This case report aims to contribute to the clinical understanding of CPF involving the mitral valve (MV), providing insights into diagnosis and treatment strategies.
