Surgical Aortic Valve Replacement Emits Twice the CO2 of TAVR: What This Means for Practice and Policy

Highlights

– A life cycle assessment (LCA) of 30 procedures found the carbon footprint of surgical aortic valve replacement (SAVR) is roughly twice that of transcatheter aortic valve replacement (TAVR) performed in either an operating room (OR-TAVR) or a catheterization laboratory (CATH-TAVR).

– Median total footprints: OR-TAVR 280–340 kg CO2e; CATH-TAVR 290–360 kg CO2e; SAVR 620–750 kg CO2e (P < .05 for SAVR vs either TAVR).
