Abstract

Introduction and objectives. Postoperative right ventricular (RV) systolic dysfunction is associated with perioperative myocardial ischemia, hypothermic cardiac arrest, cardiopulmonary bypass and pericardial injury. As myocardial acceleration during isovolumic contraction (IVA) and myocardial velocity during isovolumic contraction (IW) are little affected by loading conditions, they can predict myocardial function better than conventional parameters. We investigated the usefulness of these parameters for predicting postoperative RV systolic function after isolated heart valve surgery.
