Abstract

This analysis of the data of the obligatory quality assurance programme AQUA shows the perioperative risk as well as the procedural outcome evaluated by the observed versus expected in-hospital mortality ratio (O/E ratio) of 62,872 patients undergoing isolated surgical (sAVR), transcatheter transvascular (TV-), or transapical (TA-) aortic valve replacement (TAVI) from 2012 to 2014 in Germany. The number of TAVI procedures increased from 9,352 in 2012 to 13,278 in 2014, whereas the number of sAVR remained constant (2012: 9,949; 2014: 9,953). Between 2012 and 2014, the number of TAVI implanted in patients with a logistic EuroScore I (logESI) of ≤10 % (2012: 21 %; 2014: 26 %) as well as with a logESI <20 % (2012: 57 %; 2014: 64 %) increased. In-hospital mortality in TAVI patients decreased from 5.2 % (TV: 5.0 %; TA: 7.4 %) in 2012 to 4.2 % (TV: 3.8 %; TA: 5.5 %) in 2014, whereas it was stable for sAVR patients (2012: 2.8 %; 2014: 2.6 %). The O/E ratio of TAVI patients decreased from 0.91 (TV: 0.79; TA: 1.2) to 0.73 (TV: 0.69; TA: 0.89), whereas this ratio remained constant for sAVR patients (2012: 0.92; 2014: 0.93). In summary, estimated surgical risk, in-hospital mortality, as well as the O/E ratio for patients undergoing TAVI declined constantly during the last 3 years.
