Case
A 90-year-old man with New York Heart Association class II heart failure from severe aortic stenosis was admitted for elective TAVR. His medical history included coronary artery disease, and paroxysmal atrial fibrillation. Transthoracic echocardiogram had shown severe calcified aortic stenosis (peak velocity: 4.5 m/s, mean gradient: 51 mm Hg, aortic valve area: 0.8 cm2), 70% left ventricular ejection fraction, concentric left ventricular hypertrophy, and mild MR. In the weeks preceding TAVR, he
Discussion
Impella CP has previously been used as a rescue therapy for cardiogenic shock complicating TAVR, caused by 1 of the following: low output failure during implantation, coronary obstruction, refractory ventricular tachycardia, severe PVL, and annular rupture. Thirty-day mortality was 40%.3 Other mechanical circulatory support options including intra-aortic balloon pump, Tandem Heart (CardiacAssist, Inc, Pittsburgh, PA) and extracorporeal membrane oxygenation have also been reported. Of those,
