Abstract

We experienced a 39-year-old male patient who converted paracorporeal left ventricular assist device to HeartWare ventricular assist device (HVAD; Medtronic, Framingham, MA) as bridge-to-transplant indication. On the 10th postoperative day, the HVAD flow waveform presented periodical low pulsatility pattern. Significant pericardial hematoma was observed on the imaging studies, and he showed pulsus paradoxus. He was highly suspected of cardiac tamponade and performed thoracotomy. HVAD waveform might be a useful tool to monitor and early suspect of postoperative cardiac tamponade to consider more intensive examinations and thoracotomy before hemodynamic deterioration, although further large-scale studies are warranted to strengthen our hypothesis.
