Changing Trends of Aortic Valve Replacement Procedures in Australia

Abstract

Aortic valve replacement (AVR) is one of the most common surgeries performed in cardiac surgery operating rooms. Estimated prevalence of aortic stenosis (AS), a common indication for aortic valve replacement, is 1.48 % among those aged ≥ 55 years, suggesting 97,000 Australians living with severe AS in 2019. Transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) are 2 common approaches used for aortic valve replacement. Although TAVR is a relatively newer technique as compared to SAVR, it is slowly becoming new standard of care.
