Key result
A 31-year-old woman with severe left ventricular dysfunction and an inverted tako-tsubo contractile pattern triggered by a pheochromocytoma crisis experienced rapid recovery of cardiac function within 3 days.

Pheochromocytoma crisis can present as an 'inverted tako-tsubo' cardiomyopathy with rapid recovery of left ventricular function.
May prompt pheochromocytoma evaluation in select cases; hypothesis-generating observation that leaves open prospective validation.
Pheochromocytoma is a rare, catecholamine-secreting tumor of neuroendocrine cells. It has been documented to present atypically as myocardial ischemia, arrhythmias, or congestive heart failure. We present the case of a patient who had transient cardiomyopathy with hypokinesia of the basal portions of the left ventricle and hyperkinesia of the apex triggered by a pheochromocytoma crisis similar to that of tako-tsubo cardiomyopathy, but with an inverse left ventricular contractile pattern ('inverted tako-tsubo').

Naderi et al. (2012) conducted a case report in Pheochromocytoma-induced reverse tako-tsubo cardiomyopathy (n=1). Pheochromocytoma crisis was evaluated on Left ventricular function recovery. A 31-year-old woman with severe left ventricular dysfunction and an inverted tako-tsubo contractile pattern triggered by a pheochromocytoma crisis experienced rapid recovery of cardiac function within 3 days.
