A retrospective, transesophageal study of 51 consecutive patients receiving a left ventricular (LV) assist device (AD) over a 2-year period showed that LVAD-associated LV thrombosis (16%) was predicted by acute myocardial infarction, atrial cannulation, and postimplantation bleeding, and was associated with a fourfold increased risk of stroke compared with patients without thrombosis. LV cannulation, when using short-term LVADs, may decrease the incidence of LV thrombosis, and early transition to Heartmate-LVAD support may improve outcome.
