To compare the effectiveness of balloon-expandable and self-expanding valves in patients with low-flow, low-gradient aortic stenosis during TAVR.
Conducted observational analysis of patients with LFLG AS undergoing TAVR.
Compared outcomes between balloon-expandable and self-expanding transcatheter heart valves (THVs).
Performed multivariable analyses to evaluate risk factors for heart failure readmission.
Balloon-expandable valves showed comparable midterm survival to self-expanding valves.
Reduced risk of heart failure readmission was associated with balloon-expandable valves based on multivariable analysis.
Abstract
In patients with LFLG AS undergoing TAVR, BE and SE THVs have comparable midterm survival. BE THVs have a reduced risk of HF readmission on multivariable analysis.
