Complete atrioventricular block after atrial flow regulator implantation in a 5 kg infant.

The atrial flow regulator is a new self-expandable double-disc fenestrated device providing a calibrated inter-atrial communication. Paediatric reports are scarce. We herein describe a case of complete atrioventricular block complicating the exemption use of an atrial flow regulator in a 5-kg infant with transposition of the great arteries, ventricular septal defect, and right ventricular outflow tract obstruction.

Midline crossing right pulmonary veins with dual drainage to the left atrium.

We report the exceptional case of transcatheter treatment of a partial anomalous pulmonary venous drainage of the right lung to the innominate vein and dual drainage to the left atrium.

Familial Recurrence Patterns in Congenitally Corrected Transposition of the Great Arteries: An International Study.

Background: Congenitally corrected transposition of the great arteries (ccTGA) is a rare disease of unknown cause. We aimed to better understand familial recurrence patterns.

Methods: An international, multicentre, retrospective cohort study was conducted in 29 tertiary hospitals in 6 countries between 1990 and 2018, entailing investigation of 1043 unrelated ccTGA probands.

Off-label use of Lifetech KONAR-MF™ ventricular septal defect occluder for large patent ductus arteriosus closure in <6 ​kg infants.

Background: Device PDA closure is increasingly used in smaller patients. Major safety concerns remain when applied to <6 ​kg infants with large PDA and challenging anatomy. We aimed to report our experience with the new Konar-MF™ ventricular septal defect (VSD) occluder for transcatheter closure of large patent ductus arteriosus (PDA) in infants <6 ​kg.
