Emergency aortic valve replacement with double aorto-coronary bypass surgery was performed to treat severe intractable congestive heart failure in an 82-year-old man. Mild circumflex and left anterior descending artery lesions were present and the pressure gradient across the aortic valve was 80 mmHg despite a low cardiac output. The preoperative anteroseptal akinesia seen by two-dimensional echocardiography was normalized after surgery. Thus, even in patients with segmental left ventricular dyfunction, tight aortic stenosis might be present when concomitant mild ischemic heart disease is present.

Excessive catecholamine levels can cause myocardial damage in experimental animals. Similar observations have been made in humans following autopsy for pheochromocytoma. However, whether catecholamine crises are reversible or not remains uncertain. We report here a case in which pheochromocytoma manifested as acute pulmonary edema during an operation. Serial echocardiograms revealed that the depressed motion of the left ventricular wall was reversed after tumor removal. The plasma catecholamine level was extraordinarily high during the episode of acute pulmonary edema, and it seems that catecholamines in high concentration can directly damage the myocardium.
