Family screening for hypertrophic cardiomyopathy: Initial cardiologic assessment, and long-term follow-up of genotype-positive phenotype-negative individuals.
Int J Cardiol
December 2024
Aims: (i) Investigate the prevalence of hypertrophic cardiomyopathy (HCM) in individuals with pathogenic/likely pathogenic (P/LP) gene variants detected through family cascade testing in relatives, and (ii) evaluate phenotypic progression in genotype-positive phenotype-negative (G+/P-) individuals during follow-up.
Results: From 2000 to 2023, 273 individuals underwent cardiologic evaluation following P/LP variant detection through family screening. Upon initial evaluation, HCM was diagnosed in 128 (47 %) individuals.
Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare, potentially life-threatening genetic heart disease. Nonselective beta-blockers (BBs) are highly effective in reducing CPVT-triggered arrhythmic events. However, some patients suffer from unacceptable BB side effects and might require strategies without a BB.

- - The study examines how secondary genetic variants can influence the clinical features of individuals with primary disease-causing variants, suggesting that these modifiers play a significant role in disease expression.
- - Specifically focusing on the 16p12.1 deletion, researchers identified various rare and common variants that predisposed individuals to specific developmental issues, such as neurological defects and microcephaly.
- - By analyzing data from different cohorts, the findings indicate that the effects of primary and secondary variants on phenotype vary depending on the specific primary variant involved, highlighting the need for personalized approaches in treatment.
Background: Frequent premature ventricular contractions (PVCs) in children are usually considered benign. Symptoms and left ventricular dysfunction are indications for treatment with antiarrhythmic drugs.
Objective: This study aimed to evaluate the efficacy of flecainide vs metoprolol in reducing PVCs in children.
