OBJECTIVES: Significant coronary artery disease (CAD) is common among patients evaluated for transcatheter aortic valve implantation (TAVI). Only little data exist on outcome of patients undergoing concomitant off-pump coronary revascularization and TAVI. The goal of this study was to analyse the impact of concomitant off-pump revascularization on early clinical outcome and 2-year follow-up of patients undergoing TAVI. METHODS: A total of 70 patients with significant CAD and aortic valve stenosis were included between January 2011 and January 2016. Decision to perform concomitant off-pump coronary revascularization and TAVI was made by the interdisciplinary heart team according to the SYNTAX score. Prospectively assigned data were analysed retrospectively and follow-up was performed up to 2 years. RESULTS: Mean age was 82.2 ± 4.0 years and 43 (61.4%) patients were male. Mean logistic European system for cardiac operative risk evaluation and Society of Thoracic Surgeons European system for cardiac operative risk evaluation score were 35.9 ± 21.9% and 12.2 ± 7.9%, respectively. SYNTAX score was 29.0 ± 12.9. Access site for TAVI was transapical in 60.0% and transaortic in 40.0%. Procedural success was 94.3%. Eighty percent of the patients had none or trace paravalvular leakage after TAVI. Severe complications requiring consecutive surgical aortic valve replacement occurred in 2 patients (2.9%). The use of cardiopulmonary bypass due to haemodynamic instability or conversion to surgical aortic valve replacement was necessary in 7 patients (10.0%). Stroke occurred in 1 patient (1.4%). Re-exploration for bleeding was necessary in 6 patients (8.6%). Thirty-day mortality was 14.3%. Two-year survival was 68.4% (95% confidence interval: 55.7-81.1%). CONCLUSIONS: Simultaneously performed complete off-pump coronary revascularization is a feasible and valid option in patients with significant CAD undergoing TAVI.
