Perioperative transient left ventricular apical ballooning syndrome: Takotsubo cardiomyopathy: a review.

Transient left ventricular apical ballooning syndrome (TLVAB), also known as Takotsubo cardiomyopathy, is a cardiac syndrome characterized by transient left ventricular dysfunction in the absence of obstructive atherosclerotic coronary artery disease. An episode of emotional and/or physiologic stress frequently precedes presentation of this syndrome. TLVAB may initially present as an acute coronary syndrome characterized by chest pain, pulmonary edema, electrocardiographic changes, elevated cardiac enzymes, and cardiogenic shock.
