Pheochromocytoma-related myocardial damage following delivery.

We present the case of a 35-year-old woman whose pregnancy was complicated by the rare condition of transient pheochromocytoma-related myocardial damage. Short-duration left ventricular dysfunction was apparently caused by acute non-transmural myocardial infarction provoked by coronary artery vasospasm rather than catecholamine-induced cardiomyopathy. Forty-eight days after onset, a 50 x 55 x 35 mm tumor was excised and histologically confirmed to be a pheochromocytoma.
