Background
Within the last years TAVI—especially transfemoral/transvascular TAVI—has proven to be a valuable therapeutic option for most patients suffering from AS. Here, we present the outcome of a complete dataset of all patients undergoing aortic valve replacement in Germany in 2018.
Methods
The data of all aortic valve procedures performed in Germany in 2018 derive from the mandatory nationwide quality control program. Patients were stratified with a new version of the German Aortic valve score (AKL Score) divided in different risk stratification depending on the treatment with either a catheter based (TV-TAVI) or surgical (iSAVR) approach. In-hospital outcomes have been compared between the two approaches.
Results
19,317 transvascular (TV)–TAVI procedures were carried out. In contrast to this steady growth, the number of iSAVR andtransapical (TA) -TAVI procedures declined. In-hospital mortality after TV-TAVI (2.5%) was lower when compared to iSAVR (3.1%) as well as TA-TAVI (5.7%) in-hospital mortality after TV-TAVI was significantly lowest (Fig. 2) with an in-hospital mortality rate of 2.5%. TV-TAVI was the only approach with an observed vs. expected mortality ratio < 1 according to the used risk prediction model.
Conclusion
TV-TAVI is more often performed and shows lower in-hospital mortality than iSAVR. TV-TAVI has replaced iSAVR as the gold-standard concerning in-hospital outcome in aortic stenosis management.
