Objectives: Mechanical circulatory support for pediatric heart failure patients with the Berlin Heart EXCOR ventricular assist system is the only approved and established bridging strategy for recovery or heart transplantation. In recent years, the burden of thromboembolic events has led to modifications of the recommended antithrombotic therapy. Therefore, we aimed to assess modifications of antithrombotic practice among the European EXCOR Pediatric Investigator Group members.

Methods: 9 Melody valves had been implanted in 8 patients (pulmonary n = 7, tricuspid position n = 1). Indication for explantation included significant obstruction in 7 patients and valve insufficiency in 1 patient.
Muscular ventricular septal defect in a newborn with truncus arteriosus communis: perventricular transcatheter closure under echocardiographic guidance only, a case report.
World J Pediatr Congenit Heart Surg
October 2014
Article Synopsis
- - A newborn weighing 3.5 kg was diagnosed with a muscular ventricular septal defect (VSD) along with truncus arteriosus communis, a condition where a single artery arises from the heart instead of separate arteries.
- - The treatment involved a hybrid surgical method, which combines traditional and minimally invasive techniques.
- - The surgery focused on closing the muscular VSD while the heart was still beating, known as perventricular closure, which is a specialized approach to heart surgery.
Acute myocardial infarction (MI) is a life-threatening condition rarely encountered in neonates. The patients usually present with sudden cardiogenic shock. Clinical management in neonates is extremely challenging.

Thorac Cardiovasc Surg
June 2013
In recent years, several publications from German institutions have highlighted the need for quality assessment, complexity and risk interpretation, and assurance of sustainable structures in congenital heart surgery. In addition, there is a severe shortage of congenital cardiac surgeons in Germany. To provide quality assurance, the German Society for Thoracic and Cardiovascular Surgery (DGTHG, Deutsche Gesellschaft für Thorax-, Herz- und Gefäßchirurgie) offers a Certificate for Congenital Cardiac Surgery, which is awarded with proof of a minimal number of congenital procedures.

Patients And Methods: From 1988 to 2011, 2023 patients (age, 39.
Article Synopsis
- The study analyzes cardiac and cerebrovascular events in patients who underwent the Ross procedure, utilizing data from the German-Dutch Ross registry to inform medical professionals and patients alike.
- A total of 1,620 patients were evaluated, with findings indicating low early and late mortality rates, and high rates of freedom from reoperation on the autograft or pulmonary conduit over 1, 5, and 10 years.
- The study concludes that the Ross procedure is a valid treatment for aortic valve disease but highlights the importance of recognizing factors like preoperative aortic regurgitation and the nonreinforced technique as risks for autograft failure.
Article Synopsis
- - The study evaluates the effectiveness of autograft reinforcement interventions during the Ross procedure, focusing on their ability to preserve autograft function and reduce long-term reoperation rates over time.
- - Among 1335 adult patients, those who received reinforcement during the Root Ross procedure had a significantly lower reoperation rate (12.9% vs. 2.3% - 2.6% for other groups) and no progression of aortic regurgitation compared to those without reinforcement.
- - The findings conclude that surgical autograft stabilization techniques lead to better long-term outcomes, particularly in the Root procedure, and are recommended for maintaining autograft function.
Objective: We describe the experience from a single institution with the Norwood sequence of palliation for hypoplasia of the left heart, emphasizing complications related to placement of a conduit from the right ventricle to the pulmonary arteries and their management.
Methods: Between November, 2002 and January, 2006, we palliated 32 patients with hypoplastic left heart syndrome or its variants by placing a conduit from the right ventricle to the pulmonary arteries. We reviewed retrospectively the charts and angiograms from these patients.
