We investigated the impact on patient selection and procedural results. In total, 456 TAVR patients before (pre-COVID-19 group) and 456 TAVR patients after (COVID-19 group) the implementation of our allocation algorithm were compared. Concerning patient characteristics, the COVID-19 group revealed a higher rate of cardiac decompensations\/cardiogenic shocks (10.5% vs. 1.3%; p &lt; 0.001), severe angina pectoris (Canadian Cardiovascular Society (CCS) II, III and IV: 18.7% vs. 11.8%; p = 0.004), troponin elevation (&gt;14 ng\/L: 84.9% vs. 77%; p = 0.003) and reduced left ventricular ejection fraction (LVEF) (&lt;45%: 18.9% vs. 12%; p = 0.006). Referring to procedural characteristics, more predilatations (46.3% vs. 35.1%; p = 0.001) and a longer procedural time (80.2 min (+\/\u221229.4) vs. 66.9 min (+\/\u221217.5); p &lt; 0.001) were observed. The success rate was evenly high; no differences in safety parameters were reported. Examining the utilization of hospital resources, the COVID-19 group showed a shorter in-hospital stay (8.4 days (+\/\u22125.9) vs. 9.5 days (+\/\u22129.33); p = 0.041) and fewer TAVR patients were treated per month (39 (+\/\u22124.55) vs. 46.11 (+\/\u22127.57); p = 0.03). Our allocation algorithm supported prioritization of sicker patients with similar efficient and safe TAVR procedures. In-hospital stay could be shortened.<\/jats:p>","DOI":"10.3390\/jcdd9060189","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T10:25:12Z","timestamp":1654856712000},"page":"189","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Structured
