High thoracic epidural decreases perioperative myocardial ischemia and improves left ventricle function in aortic valve replacement alone or in addition to cabg surgery even with increased left ventricle mass index.

ABSTRACT:

Introduction

High thoracic epidural (HTE) may reduce perioperative tachyarrhythmias, respiratory complications and myocardial ischemia (MI) and it may increase coronary perfusion and myocardial oxygen balance through sympatholysis and pain control. The aim of this study is to investigate the benefit of HTE in patients undergoing aortic valve replacement (AVR) alone or in addition to coronary artery bypass graft (CABG).

Methods

This prospective randomized controlled study was conducted on 80 patients (40 with increased left ventricular mass index (LVMI) and 40 with normal LVMI) who were equally randomised (n = 40) to receive either GA with HTE (HTE group) or GA alone (GA group). Heart rate (HR), mean arterial blood pressure (MAP) and the incidence of ischemic ECG changes were
