Abstract
AIMS: Performing transcatheter aortic valve implantation (TAVI) at hospitals with only cardiology department but no cardiac surgery (CS) on-site is at great odds with current Guidelines. METHODS AND RESULTS: We analysed data from the official, prospective German Quality Assurance Registry on Aortic Valve Replacement to compare characteristics and in-hospital outcomes of patients undergoing transfemoral TAVI at hospitals with (n = 75) and without CS departments (n = 22). An interdisciplinary Heart Team was established at all centres (internal staff physicians at hospitals with on-site CS; in-house cardiologists and visiting cardiac surgical teams from collaborating hospitals at non-CS hospitals). In 2013 and 2014, 17 919 patients (81.2 ± 6.1 years, 55% females, German aortic valve (GAV) score 2.0 5.6 ± 5.8%, logistic EuroSCORE I 21.1 ± 15.4%) underwent transfemoral TAVI in Germany: 1332 (7.4%) at hospitals without on-site CS department. Patients in non-CS hospitals were older (82.1 ± 5.8 vs. 81.1 ± 6.1 years, P < 0.001), with more frequent co-morbidities. Predicted mortality risks per GAV-score 2.0 (6.1 + 5.5 vs. 5.5 ± 5.9%, P < 0.001) and logEuroSCORE I (23.2 ± 15.8 vs. 21.0 ± 15.4%, P < 0.001) were higher in patients at non-CS sites. Complications, including strokes (2.6 vs. 2.3%, P = 0.452) and in-hospital mortality (3.8 vs. 4.2%, P = 0.396), were similar in both groups. Matched-pair analysis of 555 patients in each group with identical GAV-score confirmed similar rates of intraprocedural complications (9.2 vs. 10.3%, P = 0.543), strokes (3.2% for both groups, P = 1.00), and in-hospital mortality (1.8 vs. 2.9%, P = 0.234). CONCLUSION: Although patients undergoing TAVI at hospitals without on-site CS department were older and at higher predicted perioperative death risk, major complications, and in-hospital mortality were not statistically different, suggesting the feasibility and safety of Heart Team-based TAVI at non-CS sites. These findings need confirmation in future randomized study. Published on behalf of the European Society of Cardiology. All rights reserved.
