A 17-year-old woman was resuscitated from cardiac arrest due to ventricular fibrillation and was diagnosed with concealed long QT syndrome. She underwent subcutaneous implantable cardiac defibrillator (S-ICD) implantation at our hospital. The device electrogram immediately after implantation was normal. Four days after implantation, she received an inappropriate shock. The device interrogation revealed a continuous baseline shift and frequent oversensing for low amplitude signals, followed by a shock. A chest radiograph in the orthogonal view showed entrapped subcutaneous air surrounding the distal electrode. Entrapped subcutaneous air can cause inappropriate shocks in the early period after S-ICD implantation.

Background: This study aimed to compare inappropriate shock (IAS) rates between subcutaneous implantable cardioverter-defibrillator (S-ICD) and transvenous ICD (TV-ICD) in Brugada syndrome (BrS) patients and identify risk factors for IAS in S-ICD use.
Methods: We enrolled consecutive patients with BrS who underwent ICD implantation between 2013 and 2023. Data on clinical characteristics, S-ICD screening test data, and IAS occurrence were retrospectively analyzed.

Background: The absence of practice standards in vasoactive agent usage for acute decompensated heart failure has resulted in significant treatment variability across hospitals, potentially affecting patient outcomes. This study aimed to assess temporal trends and institutional differences in vasodilator and inotrope/vasopressor utilization among patients with acute decompensated heart failure, considering their clinical phenotypes.
Methods: Data were extracted from a government-funded multicenter registry covering the Tokyo metropolitan area, comprising consecutive patients hospitalized in intensive/cardiovascular care units with a primary diagnosis of acute decompensated heart failure between January 2013 and December 2021.
Epicardial Ablation for Arrhythmogenic Disorders in Patients with Brugada Syndrome.

Clinical and Rehabilitation Cardiology Division, San Filippo Neri Hospital, 00135 Rome, Italy.
Brugada syndrome (BrS) is an inherited arrhythmogenic disorder characterized by distinct electrocardiographic patterns and an increased risk of sudden cardiac death due to ventricular arrhythmias. Effective management of BrS is essential, particularly for high-risk patients with recurrent arrhythmias. While implantable cardioverter-defibrillator (ICD) is effective in terminating life-threatening arrhythmias, it does not prevent arrhythmia onset and can lead to complications such as inappropriate shocks.

Background: Chagas cardiomyopathy (CCM) is a significant cause of ventricular arrhythmias and sudden cardiac death (SCD). Although, implantable cardiac defibrillators (ICD) have been used for all forms of non-ischemic cardiomyopathy (NICM), studies on ICD efficacy in CCM are scarce.
Objective: The present study aims to compare the long-term outcomes, mortality rates, and the occurrence of tachycardia therapies after ICD implantation in patients with CCM and NICM.
