A Sudden Change of Heart: A Case of Rapidly Reversed Stress Cardiomyopathy in a Critically Ill Patient

Abstract

We report the case of a 79-year-old woman who presented to our hospital for elective removal of an infratentorial meningioma and suffered a periprocedural cardiac arrest. Shortly after uncomplicated induction of anesthesia prior to the surgery, the patient became hypotensive and bradycardic, culminating ultimately in a cardiac arrest with pulseless electrical activity. Return of spontaneous circulation occurred within 90 seconds of arrest, but the patient remained dependent on maximal doses of epinephrine and dopamine for hemodynamic support. Echocardiography performed on the day of cardiac arrest revealed a newly depressed left ventricular ejection fraction (LVEF) of 15-20% with an apical ballooning pattern. Left heart catheterization showed no obstructive coronary lesions to explain her depressed ejection fraction. A diagnosis of stress cardiomyopathy (SCM) was made given the echocardiographic findings and absence of concomitant coronary disease. Within the next 24 hours, the patient was liberated from inotropic support, and at 6-month follow-up, her LVEF returned to 55% and she had no heart failure symptoms.
