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

ABSTRACT:

Background

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).

Methods

In this single-center retrospective cohort study, intraoperative changes in LV systolic and diastolic function were analyzed in patients undergoing TAVR from January 2012 to September 2014. Participants were categorized into two groups based on preprocedural LVEF: the low
