Popis: A 59-year-old man with nonischemic cardiomyopathy, advanced heart failure, and group 2 pulmonary hypertension underwent HeartWare left ventricular assist device (LVAD) implantation as bridge to transplantation. Off-pump LVAD implantation was performed via minimally invasive left thoracotomy and upper hemisternotomy with an estimated blood loss of 200 mL. Postoperative VAD settings were as follows: speed, 2600 rpm; power, 4 W; flow, 5.5 to 5.7 L/min; and pulsatility index (PI), 4. Aspirin 325 mg daily and warfarin were begun on postoperative day 1. Over the course of the next few days, he was extubated and optimized hemodynamically with continued inotropic support (milrinone), and a therapeutic international normalized ratio (2–3) was achieved. Before his transfer out of the intensive care unit, he underwent a transthoracic echocardiogram, …
