Article Synopsis
  • Very few studies have explored the effectiveness of subcutaneous implantable cardioverter-defibrillators (S-ICDs) in patients with congenital heart disease (CHD), which this research aims to address.
  • In a French cohort study of 4,924 patients implanted with an S-ICD, only 101 were found to have CHD, often presenting at a younger age and more often for secondary prevention compared to non-CHD patients.
  • The study found that while patients with CHD had a higher crude risk of receiving appropriate shocks from their S-ICD, this risk was not significant after adjusting for other factors, indicating that complications and inappropriate shocks were similar across both patient groups.

Article Synopsis
  • A study analyzed patients with reversible high-degree sinus node dysfunction (SND) and atrioventricular block (AVB) to find out the likelihood of needing permanent pacemakers (PPM) after hospital discharge.
  • Out of 93 patients, 28% required PPM implantation later; those who needed one typically had less frequent past hypertension and more often experienced elevated potassium levels.
  • The presence of intraventricular conduction disorders on ECG at discharge was a significant predictor for those who later needed a pacemaker, indicating that careful monitoring post-discharge is crucial.

Background: Rare genetic variants in TNNI3K encoding troponin-I interacting kinase have been linked to a distinct syndrome consisting primarily of supraventricular tachycardias and variably expressed conduction disturbance and dilated cardiomyopathy in 2 families.

Objective: The purpose of this study was to identify new genetic variants associated with inherited supraventricular tachycardias, cardiac conduction disease, and cardiomyopathy.

Methods: We conducted next generation sequencing in 3 independent multigenerational families with atrial/junctional tachycardia with or without conduction disturbance, dilated cardiomyopathy, and sudden death.

Background: Brugada syndrome (BrS) is an arrhythmogenic disease associated with sudden cardiac death (SCD) that seldom manifests or is recognized in childhood.

Objectives: The objectives of this study were to describe the clinical presentation of pediatric BrS to identify prognostic factors for risk stratification and to propose a data-based approach management.

Methods: We studied 106 patients younger than 19 years at diagnosis of BrS enrolled from 16 European hospitals.

Aims: In low-flow, low-gradient aortic stenosis (LF/LG AS), the assessment of contractile reserve (CR) by dobutamine stress echocardiography (DSE) is recommended for risk stratification and treatment strategy. However, DSE may show limitations in cases of left ventricular dyssynchrony (LVD). The impact of LVD in LF/LG AS, and the feasibility of CRT in this setting have never been evaluated.
