Early Morbidity
44 patients (39.3%) required IABP to exit the operating room, while three patients (2.7%) need intraoperative implantation of ventricular assist devices. Reoperation of deep sternal infection was performed in six patients (5.4%). Ten patients (8.9%) received continuous renal replacement therapy due to postoperative renal failure. Postoperative shunts were found in eleven patients (9.8%) by postoperative echocardiography, and only one patient underwent reoperation within 30 days after the primary procedure due to severe unstable circulation status.
