Changing haemodynamic status of patients referred for transcatheter aortic valve intervention during the COVID-19 pandemic.

ABSTRACT:

Introduction

Delays in the diagnosis and referral of aortic stenosis (AS) during the coronavirus disease 2019 (COVID-19) pandemic may have affected the haemodynamic status of AS patients. We aimed to compare clinical and haemodynamic characteristics of severe AS patients referred for transcatheter aortic valve implantation (TAVI) or balloon aortic valvuloplasty (BAV) before the pandemic versus two subsequent periods.

Methods

This study compared three 1‑year historical cohorts: a pre-COVID-19 group (PCOV), a 1st-year COVID-19 group (COV-Y1) and a 2nd-year COVID-19 group (COV-Y2). The main parameters were baseline New York Heart Association (NYHA) functional class, left ventricular ejection fraction (LVEF) and left ventricular end-diastolic pressure (LVEDP).
