Patients and Methods
The Institutional Review Board approved the study and individual patient consent was waived.
Results
Between April 2005 and April 2010, 40 patients received S-AVR as a redo procedure after previous CABG. Thirty-five patients (87.5%) were treated with biologic, 2 patients (5%) with mechanical valve prostheses, and 3 patients (7.5%) received an apical-descendens conduit.
Baseline patient characteristics are reported in Table 1. Sex distribution and comorbidities were similar in both groups, except that the TAVI patients were significantly older and presented more frequently with peripheral
Comment
The present study shows that aortic valve replacement in patients with previous CABG can be performed with favorable and similar medium-term clinical results and low mortality by S-AVR as well as by TAVI.
Patients with previous cardiac interventions—most frequently CABG—are considered to be at increased perioperative risk when undergoing redo cardiac operations and constitute 5% to 16% of all patients undergoing S-AVR [12, 13, 14]. With this study we assessed the outcome of TAVI and compared
