Résumé
For almost 35 years, the Swissworking Group for interventional Cardiology of the Swiss Society of Cardiology has evaluated and assessed the invasive diagnostic and therapeutic heart interventions performed annually in Switzerland.the aim of this survey, which was completed by 36 centres using a standardised questionnaire, was to report the data for the year 2020. Overall, 53,088 coronary angiographies with 48.8% subsequent percutaneous coronary interventions, i.e., 8.6% less than in 2019, were performed. regarding structural interventions, there were 1790 transcatheter aortic valve implantations, with a decrease of 6.4% compared with 2019.this decrease was most likely due to the coronavirus disease (COvid-19) pandemic and its consequences on the Swiss healthcare system.Copyright © 2021 Edizioni Minerva Medica.
