An 87-year-old woman died of rapidly progressive pneumonia due to Aeromonas hydrophila shortly after a near-drowning event. Autopsy showed necrotizing pneumonia and postmortem cultures of both blood and lung revealed the organism. Fulminant pneumonia should be considered in patients of a near-drowning event.(Internal Medicine 39:1128-1130, 2000)

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.

Eight cases of transient reversible segmental asynergy of the left ventricle thought not to be related to coronary artery lesions are reported. Three cases were associated with inflammatory reactions of unknown origin, and one each with lactic acidosis, abdominal surgery, hypoglycemia, tetanus and pneumonia. None of the patients had symptoms suggestive of ischemic heart disease before or after these episodes. Electrocardiograms before these episodes were all normal. Two-dimensional echocardiography was performed to evaluate abnormal electrocardiograms. Coronary angiography was performed in 4 of 8 cases and was normal in all 4 cases; 2 done as emergencies and 2 non-emergencies. Two ergonovine tests were negative. Left ventricular wall motion abnormalities. present mainly at the apex of the left ventricle, returned to normal in I to 4 weeks. Giant negative T waves in the chest leads during this recovery period were characteristic electrocardiographic features and normalized in 6 weeks on average . We believe that these episodes were not related to ischemia due to coronary artery disease, but to some metabolic humoral factors. An excellent prognosis can be expected if these abnormal metabolic circumstances can be resolved.

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.

A case of tetanus accompanied by severe reversible left ventricular motion impairment is reported. Emergent coronary angiography showed no abnormalities and large akinesis was present on left ventriculography. The plasma catecholamine level was not too high in the acute phase, therefore it is thought that the cause of this depressed left ventricular wall motion abnormality was due to some metabolite derived from tetanus.
