Abstract | OBJECTIVE: METHOD: Between April 2008 and August 2011, 512 consecutive patients underwent transcatheter aortic valve implantation. Cardiopulmonary bypass was used in 35 patients. In this special group, there were 17 men and 18 women with a mean age of 77 ± 12 years (range, 38-92 years). Left ventricular ejection fraction was a mean of 32% ± 19% (range, 10%-70%), European System for Cardiac Operative Risk Evaluation was 60% ± 27% (range, 13%-97%), and Society of Thoracic Surgeons' mortality score was 35% ± 28% (range, 4%-90%). RESULTS:
Cardiopulmonary bypass was used in 13 patients with preoperative cardiogenic shock, 11 patients with impaired heart function during the procedure, 7 patients with severely impaired left ventricular function (left ventricular ejection fraction, 17% ± 6%; range, 10%-30%), 3 patients with concomitant conventional surgical procedures, and 1 patient with impaired right ventricular function. The technical success rate was 94%, 30-day mortality was 20%, and 1-year survival was 46%. CONCLUSIONS:
