Background: Charcot-Marie-Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease.

Article Synopsis
- This study distinguishes between nondilated left ventricular cardiomyopathy (NDLVC) and dilated cardiomyopathy (DCM) by using cardiac magnetic resonance (CMR) and genetic testing on 462 patients across four centers.
- Findings showed that NDLVC patients had better heart function and a higher prevalence of specific genetic variants compared to those with DCM, highlighting significant differences in their conditions.
- The presence of septal late gadolinium enhancement and other factors like LV dilatation, age, and arrhythmias were identified as strong predictors for serious cardiac events, such as sudden cardiac death.
Non-sustained Ventricular Tachycardia as a Presentation of Arrhythmogenic Right Ventricular Cardiomyopathy.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare disorder with familial (autosomal dominant) predisposition and can be challenging to diagnose. Non-sustained ventricular tachycardia (NSVT) is a relatively uncommon and short-lived arrhythmia when seen in the general, healthy population. NSVT with a left bundle branch block morphology is usually idiopathic but may also be seen in ARVC.

Exercise has a deleterious effect on the phenotypic expression of arrhythmogenic right ventricular cardiomyopathy (ARVC) and increases the risk of sudden death. The aim of the study was to determine the prevalence and correlates of exercise-induced arrhythmias during exercise tolerance test (ETT) in patients with ARVC. Between 2010 and 2019, 30 (47% males, mean age 42 ± 12 years) consecutive patients with a definite diagnosis of ARVC underwent a full genotypic and phenotypic characterization at our center.

Article Synopsis
- The study examined the relationship between ventricular arrhythmias (VA) in competitive athletes and cardiac abnormalities revealed by cardiac magnetic resonance (CMR) imaging.
- Key characteristics of VA, such as the number, shape, and behavior during exercise tests, were analyzed to determine their ability to predict CMR findings.
- Results showed that certain VA features, particularly varied shapes and responses during exercise, were significantly associated with hidden myocardial issues, underscoring the importance of thorough cardiac evaluation in athletes.
