Patients and study design
Between January 2010 and December 2017 a total of 2.224 patients underwent TAVR at our institution. Out of these, 77 patients presented with a failed aortic bioprosthesis and were eligible for VIV-TAVR. Predominant mode of failure was stenosis (88.3%). Mean patient’s age was 79.4 ± 5.8 years. The established risk calculators by means of STS PROM (5.79 ± 2.63%) and logistic EuroSCORE (30.8 ± 15.7%) proofed the patients to be at high surgical risk.
The present study is a retrospective data analysis out of the hospital’s database. We recorded and analyzed pre-, intra- and postoperative data. All hospital survivors were supposed to undergo echocardiographic control after 1, 2 and 3 years during regular follow-up care. Corresponding completeness of follow up was 100% within the follow-up survivors. Follow-up time ranged up to 2.600 days. The study was reviewed and approved by the institutional review board at University Heart Center Dresden, Medical Faculty “Carl Gustav Carus” at Technical University of Dresden (Dresden, Germany).
