Immediate change following valve deployment in left ventricular systolic and diastolic functions in transcatheter aortic valve replacement: a retrospective cohort study

Transcatheter aortic valve replacement (TAVR) is an effective treatment for aortic valve disorder. Several studies have reported improvements in systolic and diastolic function following TAVR. However, few studies have addressed immediate post-deployment changes. Therefore, this study examines left ventricular (LV) systolic and diastolic function changes immediately after valve deployment in TAVR patients, distinguishing between those with normal and impaired LV ejection fraction (LVEF).
