Determinants of Discrepancy in the Left Ventricular Systolic Function Evaluation Between Preoperative and Intraoperative Evaluations

Abstract

<jats:p> Unexpectedly decreased left ventricular global systolic function can be difficult to manage, even for patients undergoing elective cardiac surgery, and should prompt a multidisciplinary discussion. Therefore, in this review, we discuss the evidence describing key perioperative variables expected to influence left ventricular systolic function to facilitate this discussion. </jats:p>

“…11 In a review discussing reasons for discrepancies in left ventricular systolic function between preoperative transthoracic echocardiograms and TEE, Spencer et al tease out a number of important perioperative changes that can influence left ventricular ejection fraction determinations and may ultimately affect management. 12 They address progression of valvular, functional, and ischemic etiologies in the period between evaluations, key hemodynamic changes present under anesthesia and mechanical ventilation, drug effects, and anatomical considerations, specifically open chest and open pericardial physiology. Understanding and anticipating these changes and their contribution to left ventricular systolic function is crucial to our perioperative management of these complicated patients.…”
