Abstract
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to deferral of many non-urgent procedures in most healthcare systems worldwide. With this study we aimed to quantify the impact of COVID-19 on interventional treatment of structural heart disease (SHD) in Italy. METHODS: Numbers of transfemoral transcatheter aortic valve replacement (TAVR), percutaneous mitral valve repair (PMVR), left atrial appendage occlusion (LAAO), patent foramen ovale (PFO) closures performed over a 4-week period during the national lockdown in Italian centers performing over 60 structural heart interventions (SHI)/year were compared with the same 4-week period in 2019. Incidence rate reductions (IRR) were estimated by zero-inflated negative binomial regression. RESULTS: According to our nationwide analysis, SHIs were reduced by 79% as compared to the same period in 2019 (IRR 0.21, 95% confidence interval [CI] 0.15-0.29). This reduction was more substantial for PFO closure (IRR 0.03, 95% CI 0.01-0.07), LAAO (IRR 0.11, 95% CI 0.05-0.25) and PMVR (IRR 0.12, 95% CI 0.04-0.36) as compared to TAVR (IRR 0.31, 95% CI 0.22-0.47). CONCLUSIONS: The COVID-19 pandemic caused a 79% drop in SHI volumes in Italy. PFO closure, LAAO and PMVR decreased more significantly as compared to TAVR. Further studies are needed to evaluate the impact of this reduction on outcomes of patients with SHD.
