Acute Reversible Stress-Induced Cardiomyopathy Associated with Cesarean Delivery under Spinal Anesthesia

Abstract

Stress-induced cardiomyopathy (SIC), also known as transient left ventricular apical ballooning or Tako-tsubo cardiomyopathy, is characterized by reversible left ventricular dysfunction, chest pain or dyspnea, ST-segment elevation, and minor elevations in serum levels of cardiac enzymes, in the absence of significant coronary artery disease.1 Although its pathogenesis is incompletely understood, intense emotional or physical stress is a well-recognized precipitant.2 We present a case of SIC with severe left ventricular dysfunction but minimal ECG changes in a young, woman who received spinal anesthesia for elective cesarean delivery. A 31-year-old healthy woman was admitted at 40 weeks gestation for elective repeat cesarean delivery. Both her previous and current pregnancies were uncomplicated. Her first cesarean delivery was performed uneventfully with epidural anesthesia. She had no family history of heart disease and appeared calm on entry into the operating room. Successful spinal anesthesia was achieved …
