Aortic valve replacement –
TAVI and sAVR in comparison

The German Aortic Valve Registry already counts more than 18 000 implantations of aortic valves. However, long-term comparison of the procedures so far is only possible to a limited extent, mainly because TAVI patients are on average 12 years older than sAVR patients.
In accordance with the selection criteria, 13 223 patients remained in the
Of these, 4 157 underwent TAVI and 9 066 underwent sAVR in 2011 and 2012. The main endpoint of the evaluation was 5-year all-cause mortality.The in-hospital mortality of TAVI versus sAVR was 4.1% versus 3.7% (P=0.669). During 5-year follow-up, 763 deaths were reported (41.9%) among patients treated with TAVI compared with 552 compared with 552 (30.3%) deaths after sAVR. There were no significant differences in the endpoints of in-hospital stroke, myocardial infarction, or temporary or chronic need for dialysis. As already found in other studies, TAVI patients were much more likely to have an in-hospital stroke (13.7 %) than sAVR patients (4.4%) with pacemaker preoperatively. This group had a worse prognosis than TAVI patients without a pacemaker. The access – transfemoral or transapical – had no prognostic significance.
