Takotsubo cardiomyopathy (TCMP), also known as stress cardiomyopathy or broken-heart syndrome, is an increasingly recognized form of transient left ventricular (LV) dysfunction that is often completely reversible. 1–4 It is diagnosed in 1% to 2% of patients initially presenting with symptoms suggestive of acute coronary syndrome. 2 It often presents with dyspnea, hypotension, syncope, elevated troponin levels, and ST elevations or T wave inversions on electrocardiography. 1 Coronary angiography classically reveals normal coronary arteries with no significant stenosis, though bystander coronary disease could be present, which is often mild and not severe enough to account for the degree of ventricular dysfunction. 1, 2 Complications can occur early in its course and include arrhythmia, thrombus formation, LV outlet tract obstruction, ventricular rupture, cardiogenic shock, and cardiac arrest. 1, 3 An up to 8% mortality rate has been reported with excellent recovery in 95%. 3 Classically it has been described following a physical and emotional event, with recurrence rates of 10% to 11% on revival of triggering factors. 1Several variants of TCMP have been described. The typical or apical variant consists of a hyperkinetic LV base with focal apical akinesis resulting in apical ballooning and reduced ejection fraction. Other variants such as the inverted or basal pattern (circumferential basal hypokinesis and apical hypercontractility), the mid LV variant (circumferential midventricular hypokinesis and both basal and apical hypercontractility), and the biventricular apical and right ventricular pattern have been described. 1, 4
