Left ventricle reconstruction and heartmate3 implantation. The "double patch technique"

Background: HeartMate 3 is a left ventricular assist device, composed of a centrifugal pump. It can be applied as a myocardial recovery, a bridge to transplant, or a destination therapy, in the treatment of patients with left ventricular heart failure. Methods: Herein we describe a technique applied against a giant aneurysmal dilatation, which combines a surgical device implantation and a left ventricular reconstruction using a double patch. Results: The patch minimizes thrombotic risk thanks to its internal bovine pericardium layer, which is in contact with blood. Conclusions: The outlined technique is relatively reproducible and safe in a selected group of patients, as it employs a high-quality device and enables the restoration of an appropriate ventricular geometry.
