Time From First Contact With Heart Team to Transcatheter Aortic Valve Replacement in the COVID-19 Era.

Abstract

Transcatheter aortic valve replacement (TAVR) has become the dominant form of aortic valve replacement in the United States. During the Coronavirus disease 2019 (COVID-19) pandemic, access to elective surgical care was decreased, particularly for TAVR patients. In this study, we examine the impact of each COVID-19 "wave," on our patient's access to TAVR procedures and their associated outcomes. Methods: After institutional review board approval, we conducted a retrospective review of a prospectively maintained database and a review of our own center's database to assess time to TAVR pre-COVID-19and during internally defined COVID-19 "waves." Statistical analysis was conducted via a t-test. We measured the time from first contact to TAVR and compared each COVID-19 wave to our institution's pre-COVID-19 data. During Wave 1 and 2 of COVID-19, our mean time to TAVR increased significantly to 68.44 ± 48.66 days (p = 0.05) and 68.94 ± 53.16 days (p = 0.02), respectively. All three COVID-19 waves demonstrated a statistically significant increase in all-cause mortality post-operatively (PO) with mean PO mortality of 2.5 (p = 0.0035), 1.33 (p = 0.0009), and 0.67 (p = 0.006), respectively, compared to pre-COVID-19 data. Conclusions: Multiple studies have shown that increased time from first contact to TAVR results in increased morbidity and mortality. COVID-19 increased our institution's time to TAVR significantly across two waves with an increase in all-cause mortality in each wave. This study highlights the importance that institutions should develop mechanisms to ensure access to care during crises so that patients do not face potentially avoidable harm.
