Abstract
Introduction
The STEMI-DTU pilot study tested the early safety and practical feasibility of left ventricular (LV) unloading with a trans-valvular pump before reperfusion. In the intent-to-treat cohort, no difference was observed for microvascular obstruction (MVO) or infarct size (IS) normalized to either the area at risk (AAR) at 3–5 days or total LV mass (TLVM) at 3–5 days We now report a per protocol analysis of the STEMI-DTU pilot study.
