Intraoperative Course of Left Ventricular Diastolic Strain in Surgical Valve Replacement for Severe Aortic Valve Stenosis.

ABSTRACT:

Purpose

Assessment of LV diastolic dysfunction (LVDD) poses challenges due to the dynamic changes of loading conditions in the perioperative course. Diastolic strain-based measures showed to be less load dependent, but data in aortic valve replacement (AVR) surgery remains sparse to date. Therefore, we aimed to explore the feasibility to assess these measurements and to describe the intraoperative course in this patient population.

Methods

Prospective observational study including 30 adult patients. Intraoperative transesophageal echocardiography (TEE) was performed after induction of anesthesia [T1], after termination of cardiopulmonary bypass [T2], and after sternal closure [T3]. TEE assessment included the evaluation of peak longitudinal strain rate during isovolumetric r
