RESUMEN
Pheochromocytoma is a rare neuroendocrine tumor with a highly variable clinical presentation. The serious and potentially lethal cardiovascular complications of these tumors are related to the effects of secreted catecholamines. We describe a case of a 50-year-old woman urgently admitted to our hospital because of symptoms and clinical and instrumental findings consistent with an acute coronary syndrome complicated by acute heart failure. Urgent coronary angiography showed normal coronary arteries. During her hospital stay, the recurrence of episodes characterized by a sudden increase in blood pressure, cold sweating, and nausea allowed us to hypothesize a pheochromocytoma. The diagnosis was confirmed by elevated levels of urinary catecholamines and by the finding of a left adrenal mass on magnetic resonance imaging. The patient underwent left adrenalectomy. Therefore, the initial diagnosis was critically reappraised and reviewed as a cardiac manifestation of a pheochromocytoma during catecholaminergic crisis.

A 65-year-old man with stable angina refractory to medical therapy and with a low-threshold myocardial ischemia at ECG stress testing was referred for coronary angiography. The coronary angiogram showed an ostial subocclusive stenosis of a developed first diagonal branch located just upstream of a subocclusive stenosis of the mid left anterior descending (LAD) coronary artery, occluded distally, and a coronary collateral for LAD from a developed right ventricular branch arising with separate ostia from the right sinus of Valsalva. We discuss the diagnostic interpretation of this coronary anomaly and some aspects regarding the percutaneous treatment of bifurcations.
