Levosimendan in congenital cardiac surgery: a randomized, double-blind clinical trial.

Objective: In this study, the authors used a continuous infusion of either levosimendan or milrinone as inotropic support after corrective congenital cardiac surgery. The hemodynamic and biochemical parameters were compared.

Design: A prospective, randomized, double-blind clinical study.

Role of congenital long-QT syndrome in unexplained sudden infant death: proposal for an electrocardiographic screening in relatives.

Introduction: Congenital long-QT syndrome (LQTS) is a sporadic or familial inherited arrhythmia. It can lead to sudden death by ventricular fibrillation which occurs at any age but particularly during infancy. Recent studies of postmortem molecular analysis in infants who died of unexplained sudden infant death syndrome (SIDS) showed abnormal mutations to LQTS in 10% to 12%.
