Prenatal Identification of Intracardiac Mass Expedites Surgical Management of Capillary-Venous Malformation.
JACC Case Rep
December 2024

Fetal and neonatal cardiac tumors are rare and often benign. Clinical presentation is primarily related to mass effect, pericardial effusion or arrhythmia. Prenatal detection can assist with risk assessment and inform optimal delivery plan and postnatal management.

JACC Clin Electrophysiol
January 2025
Montreal Heart Institute, Montreal, Québec, Canada.
Background: Ventricular tachycardia (VT) substrate characteristics before transcatheter pulmonary valve replacement (TPVR) in repaired tetralogy of Fallot (rTOF) are unknown.
Objectives: In this study, the authors sought to evaluate substrates for sustained monomorphic VT before TPVR in rTOF.
Methods: Retrospective (2017 to 2021) and prospective (commencing 2021) rTOF patients with native right ventricular outflow tract referred for electrophysiology study (EPS) before TPVR were included.
An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

JACC Adv
December 2024
Department of Cardiology, Boston Children's Hospital, Boston, Massachusetts, USA.
Background: Atrial septal defects (ASDs) are a common cause of congenital heart disease worldwide.
Objectives: The purpose of the study was to assess change over time in surgical outcomes for ASD repair and identify patient-level risk factors for adverse postoperative outcomes.
Methods: We analyzed cases of isolated ASD in patients <18 years from 2010 to 2020 from 71 sites participating in the International Quality Improvement Collaborative for Congenital Heart Disease.
Catheter ablation of atrial flutter in an adult with a univentricular heart, common atrium, and single atrioventricular valve: a case report-'complex things don't always require a complex solution'.
Eur Heart J Case Rep
January 2025
Cardiac Electrophysiology, National Medical Center 'November 20th', ISSSTE, Av. Felix Cuevas #540, Col. Del Valle Del. Benito Juarez, C.P. 03100 Mexico City, Mexico.
Background: The 'univentricular' heart encompasses a variety of congenital cardiac defects characterized by a single functional ventricle and an underdeveloped ventricular chamber. Surgical intervention, typically in infancy or childhood, aims to regulate pulmonary blood flow volume. In adulthood, untreated patients may experience limitations in physical activity and elevated morbidity due to persistent cyanosis and arrhythmias, notably after the Fontan procedure.
