Establishing the Diagnosis of Inverted Stress Cardiomyopathy in a Patient with Cardiac Arrest during General Anesthesia: A Potential Role of Myocardial Strain?

In cardiac arrest survivors, postresuscitation myocardial stunning usually presents as either global left ventricular dysfunction or regional dyssynergy including the various forms of stress cardiomyopathy, in which rare variants may be difficult to diagnose. We present a patient with cardiac arrest during general anesthesia, in whom speckle tracking–derived myocardial strain helped to distinguish between the inverted variant of stress cardiomyopathy and global postresuscitation myocardial stunning.
