Reason

Due to organisational reasons in reporting 181 TAVI cases from the University Hospital Zurich had not been included and have now been added. 

Summary

Regarding structural interventions, there were 1971 (not 1790) transcatheter aortic valve implantations, comparable with 2019 (and not decreased). This The decrease in coronary interventions was most likely due to the Coronavirus Disease (COVID-19) pandemic and its consequences on the Swiss healthcare system. Regarding structural interventions, there were 1971 (not 1790) transcatheter aortic valve implantations, comparable with a decrease of 6.4% compared to 2019. The decrease in coronary interventions was most likely due to the Coronavirus Disease (COVID-19) pandemic and its consequences on the Swiss healthcare system. 

Results

Interventions for structural heart disease

First sentence deleted ("For the first time since its clinical introduction in Switzerland in 2007 and similarly to CAG, cases of annually performed transcatheter aortic valve implantations (TAVI) decreased in 2020 compared to the preceding year"). 

We observed an overall comparable number of interventions (Figure 3 and 4) (and not a reduction of interventions). In 2020, 1971 (1790) TAVIs were performed with femoral access being used in 94% and trans-apical in 2.7% of all implantations (Table 5).

Figures in cells of row "Zürich, University Hospital" and columns "Total numbers of TAVIs" "in 2020" and "in 2019" have been modified, thus also those in the corresponding cells of row "Total"

Conclusion

The national numbers of 2020, as collected by the Swiss PCI Survey, show a decrease in coronary interventions.

TAVI cases were comparable to the preceding year.
