Results
Majority of the surgical valves were stented (94.8%) with a mean
labeled size of 23.1±2.3mm and true-ID of 20.4±2.6mm. A true-ID ≤21mm
had 58.4% of the patients. Self-expanding valves were implanted in
68.8% (mean labeled size 24.1±1.8mm) and balloon-expanded in 31.2%
(mean size 24.1±1.8mm). No patient died intraoperatively. Hospital
mortality was 1.3% and three-years survival 57.1%. All patients
experienced an initial significant dPmean-reduction to 16.8±7.1mmHg.
After 3-years mean dPmean raised to 26.0±12.2mmHg. This observation was
independent from true-ID or type of TAVR-prosthesis. Patients with a
true-ID ≤21mm had a higher initial (18.3±5.3mmHg vs. 14.9±7.1mmHg;
p=0.005) and dPmean after 1-year (29.2±8.2mmHg vs. 13.0±6.7mmHg;
p=0.004). There were no significant differences in survival.
