Serial echocardiography using tissue Doppler and speckle tracking imaging to monitor right ventricular failure before and after left ventricular assist device surgery.

ABSTRACT:

Objectives

This study aimed to investigate the utility of serial tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE) for monitoring right ventricular failure (RVF) after left ventricular assist device (LVAD) surgery.

Background

RVF post-LVAD is a devastating adverse event.

Methods

The authors prospectively studied 68 patients undergoing elective LVAD surgery. Echocardiograms were performed within 72 h before and 72 h after surgery. RVF was pre-specified as: 1) the need for salvage right ventricular assist device (RVAD); or 2) persistent need for inotrope and/or pulmonary vasodilator therapy 14 days after surgery. Patients were classified as Group RVF or Group Non-RVF.

Results

A total of 24 patients (35.3%) met criteria for RVF. Preoperative
