COVID-19 has caused the deferral of millions of elective procedures, likely resulting in a backlog of cases. We estimate the number of postponed surgical aortic valve replacement (sAVR) and transcatheter aortic valve replacement (TAVR) procedures during the first two waves of the COVID-19 pandemic in Germany.
Using German national records, all isolated TAVR and sAVR procedures between 2007 and 2020 were identified. Using weekly TAVR and sAVR procedures between 2017 and 2019, we created a forecast for 2020 and compared it with the observed number of procedures in 2020.
In Germany, a total of 225,398 isolated sAVR and 159,638 isolated TAVR procedures were conducted between 2007 and 2020 that were included in our analysis. The reduction in all AVR procedures (sAVR and TAVR) for the entire year 2020 was 19.07% (95%CI: 15.19-22.95%). During the first wave of the pandemic (week 12-21), the mean weekly reduction was 32.06% (23.44-40.68%) and during the second wave of the pandemic (week 41-52), the mean weekly reduction was 25.58% (14.19-36.97%). The number of sAVR procedures decreased more than the number of TAVR procedures (24.63% vs. 16.42% for the entire year 2020).
The first year of the COVID-19 pandemic saw a substantial postponing of AVR procedures in Germany. Postponing was higher for sAVR than for TAVR procedures and less pronounced during the second wave of the COVID-19 pandemic.
COVID-19 导致数以百万计的择期手术被推迟，可能导致积压病例。我们估计了德国 COVID-19 大流行的前两个波次中，外科主动脉瓣置换术（sAVR）和经导管主动脉瓣置换术（TAVR）被推迟的手术数量。
使用德国国家记录，确定了 2007 年至 2020 年间所有孤立的 TAVR 和 sAVR 手术。使用 2017 年至 2019 年每周 TAVR 和 sAVR 手术数量，我们对 2020 年进行了预测，并将其与 2020 年实际手术数量进行了比较。
在德国，2007 年至 2020 年间共进行了 225398 例孤立性 sAVR 和 159638 例孤立性 TAVR 手术，这些手术都包含在我们的分析中。2020 年所有 AVR 手术（sAVR 和 TAVR）减少了 19.07%（95%CI：15.19-22.95%）。在大流行的第一波（第 12-21 周），每周平均减少 32.06%（23.44-40.68%），在大流行的第二波（第 41-52 周），每周平均减少 25.58%（14.19-36.97%）。sAVR 手术的数量减少超过了 TAVR 手术的数量（2020 年全年减少 24.63%，TAVR 手术减少 16.42%）。
COVID-19 大流行的第一年，德国大量推迟了 AVR 手术。sAVR 手术的推迟比 TAVR 手术更为明显，而在 COVID-19 大流行的第二波中则不太明显。
