摘要

OBJECTIVES: Left ventricular assist device (LVAD) implantation has become an effective treatment for end-stage heart failure patients. However, LVAD support disrupts the natural intracavitary blood flow path through the heart, introducing flow patterns potentially associated with thrombosis especially around the inflow cannula. We present initial insights into in vitro 4D flow magnetic resonance imaging (MRI)-based analysis of flow patterns and an enzyme-activated milk test in a porcine left ventricular (LV) model during LVAD support, in a standard implant technique and in combination with a novel cone-shaped LV sparing prosthesis.
