Discussion:
Durable mechanical circulatory support devices, such as LVADs, have
improved heart failure outcomes when used as destination therapy
compared to medical treatment alone 1. Pump thrombosis
is a complication of LVAD implantation, affecting approximately 5% of
the patients 2. Flow obstruction of the HVAD can be
classified into pre-pump obstruction, in-pump obstruction, and post-pump
blood flow obstruction (Figure 1).
