[Outpatient coronary angiography and percutaneous coronary interventions before and after the COVID-19 pandemic: experience of the Versailles hospital centre].

Background: Same day discharge (SDD) diagnostic coronary angiography and percutaneous coronary interventions (PCIs) are increasingly performed, and indications extend to more complex procedures and more fragile patients. We report the evolution of SDD interventional cardiology activity in our centre since 2016, particularly before and after the COVID-19 pandemic. Secondarily, we analysed the feasibility and safety of SDD PCI.

Materials And Methods: We analysed the number and percentage of SDD coronary angiograms and PCIs (elective or ad hoc), during 4 periods of 11 months each, from September 2016 to July 2024. Periods 1 and 2 took place before COVID-19, periods 3 and 4 after. We also compared the rate of complications and conversion to hospitalisation between periods 1-2 and 4.

Results: A total of 9587 procedures were analysed, including 1558 SDD procedures. The total number of SDD interventional cardiology procedures increased progressively over the 4 periods, from 146 SDD procedures (7.5%) in 2016-2017 to 620 (27.2%) in 2023-2024. This increase included both diagnostic coronary angiograms (respectively: 10.9%; 12.2%; 33.6% then 28.9%) and PCIs (respectively: 0.9%; 5.6%; 16.1% then 24.4%). In the immediate post-COVID-19 period, a significant increase, uncorrelated with the natural progression, was observed for SDD diagnostic coronary angiography and ad-hoc PCI. There were no deaths or serious complications, the rate of minor complications (1.1%) and conversion to conventional hospitalisation (4.5%) were low.

Conclusion: Provided a careful patient selection and rigorous organisation, SDD coronary angiography and PCI can safely be performed. The increase in the SDD interventional procedures, favoured by organisational (COVID-19) or economic constraints, need to be amplified.
