Key result
The COVID-19 pandemic was associated with a 9.15% decrease in coronary procedures but comparable all-cause in-hospital mortality for coronary interventions (1.3% during peak vs. 1.4% before).
Why the study?
The study evaluated trends in coronary and structural interventional procedures over 16 years in Switzerland and the impact of the COVID-19 pandemic, considering the global burden of cardiovascular disease.

What are the 16-year trends in coronary and structural heart interventions in Switzerland, and what was the impact of the COVID-19 pandemic?
Absolute Event Rate: 1.3% vs 1.4%
Coronary and structural interventions have steadily increased in Switzerland over 16 years, with the COVID-19 pandemic causing only a minor, transient reduction in coronary procedures without affecting in-hospital mortality.
Documents rising procedural demand for resource planning; leaves open questions on appropriateness and outcomes.
BACKGROUND: Considering the global burden of cardiovascular disease, we analysed trends in interventional coronary and structural procedures over the past 16 years (2005-2021), using continuous data from the Swiss national registry. METHODS: Based on a standardised questionnaire, data on coronary and structural interventions in Switzerland were assessed by the Working Group Interventional Cardiology of the Swiss Society of Cardiology (SSC). Here, we analysed the trend of annually performed interventions from 2005 to 2021 in Switzerland and the impact of the COVID-19 pandemic. RESULTS: We observed a constant increase in the total number of cases (including coronary angiographies (CA) and percutaneous coronary interventions (PCI)) from 36,436 cases in 2005 to 56,555 cases in 2021 (+55%). With 18 cases in 2007, TAVI procedures have increased to 2004 cases in 2021. During the early phase of the COVID-19 pandemic in 2020, a slight decrease in CAs and PCIs of 9.15% was observed. In contrast, we did not observe an impact of the COVID-19 pandemic on the number of no TAVI procedures. Most importantly, all cause in-hospital mortality for coronary interventions before and during the peak of the COVID-19 pandemic was comparable (1.4% vs. 1.3%). CONCLUSION: Over a 16-year period, we observed an upward trend in diagnostic and therapeutic procedures for coronary as well as structural heart disease, with only a small short-term impact of the COVID-19 pandemic on interventions and a similar procedure-related in-hospital-mortality in Switzerland.

Wagener et al. (2022) conducted an observational in Coronary and structural heart disease. COVID-19 pandemic vs. Pre-pandemic period was evaluated on All-cause in-hospital mortality for coronary interventions. The COVID-19 pandemic was associated with a 9.15% decrease in coronary procedures but comparable all-cause in-hospital mortality for coronary interventions (1.3% during peak vs. 1.4% before).
