Development of right ventricular electromechanical dyssynchrony following surgical repair of tetralogy of Fallot in infants.
Front Pediatr

Division of Pediatric Cardiology, Division of Pediatrics, Children's Mercy Hospital, University of Missouri-Kansas City, Kansas City, MO, United States.
Background: In adolescents and adults with tetralogy of Fallot (TOF), right ventricle (RV) electromechanical dyssynchrony (EMD) due to right bundle branch block (RBBB) is associated with reduced exercise capacity and RV dysfunction. While the development of RBBB following surgical repair of tetralogy of Fallot (rTOF) is a frequent sequela, it is not known whether EMD is present in every patient immediately following rTOF. The specific timing of the onset of RBBB following rTOF therefore provides an opportunity to assess whether acute RBBB is associated with the simultaneous acquisition of EMD.

Due to its hemodynamic stability, ketamine is a commonly used anesthetic agent for sedation during small procedures in the critical care unit. We report a case of an 8-year-old girl, previously diagnosed with tetralogy of Fallot who presented for operative correction of the congenital anomaly. She underwent a successful operation and recovered smoothly.

TBCK (TBC1 Domain-Containing Kinase) encodes a protein playing a role in actin organization and cell growth/proliferation via the mTOR signaling pathway. Deleterious biallelic TBCK variants cause Hypotonia, infantile, with psychomotor retardation and characteristic facies 3. We report on three affected sibs, also displaying cardiac malformations.

Department of Anaesthesiology, All India Institute of Medical Sciences, Kalyani, Kolkata.
This study evaluated transcatheter approach for relieving right ventricular outflow tract (RVOT) obstruction using combined non-compliant balloon dilatation of the RVOT and conal artery occlusion in patients with Tetralogy of Fallot (TOF), both uncorrected and post-intra-cardiac repair (ICR) restenosis. A prospective study was conducted from January 2022 to June 2023, including 40 symptomatic patients aged over 12 years with RVOT obstruction in TOF. Exclusion criteria included moderate to severe pulmonary regurgitation.

Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.
Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.
