The Fate of Mitral Valve Surgery in the Pediatric Age: A 25-Year Single-Center Experience.

The aim of this study was to evaluate the natural history of patients after mitral valve intervention in the pediatric age. This is a retrospective study including all patients who underwent mitral valve surgery from 1998 to 2022. The patients' surgical reports, postoperative records, and ambulatory visits were reviewed.

The Impact of Dominant Ventricular Morphology on the Early Postoperative Course After the Glenn Procedure.

The dominant ventricular morphology affects both the early and late outcomes of the Fontan procedure, but its impact on the patients' status immediately following the Glenn procedure is unknown. This study aims to evaluate the effect of the infants' dominant ventricular morphology on the immediate course after undergoing the Glenn procedure. This single-center, retrospective study included all patients who underwent the Glenn procedure between October 2003 and May 2016.

Normothermic Versus Hypothermic Norwood Procedure.

Background: Either deep hypothermia with circulatory arrest or hypothermic perfusion with antegrade selective cerebral perfusion is used during the Norwood procedure for hypoplastic left heart syndrome. Normothermic perfusion has been described for pediatric patients. The aim of this study was to compare the early outcomes of patients undergoing the Norwood procedure with antegrade selective cerebral perfusion under hypothermia with the procedure under normothermia.

Novel cfDNA Methylation Biomarkers Reveal Delayed Cardiac Cell Death after Open-heart Surgery.

The use of cardiopulmonary bypass (CPB) is thought to cause delayed cardiac damage. DNA methylation-based liquid biopsies are novel biomarkers for monitoring acute cardiac cell death. We assessed cell-free DNA molecules as markers for cardiac damage after open-heart surgery.

Dominant Ventricular Morphology and Early Postoperative Course After the Fontan Procedure.

Background: Single ventricle heart disease comprises a wide variety of critical heart defects that lead to the provision of systemic cardiac output by one dominant ventricle. It requires staged surgical palliation that culminates in Fontan circulation. Dominant ventricular morphology in single ventricle patients reportedly has an impact on postoperative morbidity and mortality with varying results.
