Abstract
We report an infant with hypertrophic cardiomyopathy who underwent biventricular assist device placement with two 15-mL Berlin Heart EXCOR pediatric ventricular assist devices using an alternative atrial cannulation strategy. The systemic circulation was supported by left atrium (LA) to aorta cannulation. The LA was accessed through the right atrium by extending a 6-mm EXCOR cannula with a Gore-Tex graft connected to an atrial septal defect. The pulmonary circulation was supported with cannulation of the right atrium to pulmonary artery. This alternative cannulation strategy facilitated effective biventricular support and may be applicable to other patients with hypertrophic or restrictive physiology.
