Percutaneous closure of patent ductus arteriosus with the Nit-Occlud patent ductus arteriosus device in 268 consecutive cases.

Background: The pfm Nit-Occlud patent ductus arteriosus (PDA) device is well established for interventional closure of PDA. However, there are still limited data concerning its efficacy and follow-up in larger patient groups.

Aims: This study aimed to evaluate the safety and efficacy of the Nit-Occlud PDA device, implanted both through transpulmonary and transaortic approach, in a large cohort.

Surgical treatment of pulmonary atresia with major aortopulmonary collateral arteries in 83 consecutive patients.

Objectives: This article reports the safety and efficacy of a morphology-based algorithm for the surgical management of pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries.

Methods: A total of 83 patients were operated from 2007 to 2014 using 3 surgical approaches: one-stage total repair, one-stage unifocalization with central shunt and delayed total repair and multistage unifocalization with subsequent total repair. Patients were divided into 2 groups depending on the surgical strategy used to choose the surgical approach.
