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).
