    Abstract:
    A 76-year-old man had an extensively calcified left ventricular pseudoaneurysm which was a sequela of acute myocardial infarction suffered 22 years ago. He experienced acute anterolateral myocardial infarction in January 1964. In March 1964, the presence of a left ventricular aneurysm was suspected by chest radiography and fluoroscopy. He was, however, in good health since then. In April 1986, when he was admitted for treatment of acute bronchitis, a large calcified density was found in the left ventricular region on chest radiography. The electrocardiogram was compatible with an old anterolateral myocardial infarction. Two-dimensional echocardiography showed an immobile portion of the left ventricle which contained "moya-moya" (sluggish, smoky) echoes. A saccular aneurysm of the left ventricle was confirmed by radioisotope cardiac pool scans, reconstruction CT and left ventriculography. Due to the poor general condition of the patient, we followed his course without surgery. He died in October 1986. At autopsy, the pseudoaneurysm was markedly calcified, and its wall was adherent to the parietal pericardium. Histologically, the pseudoaneurysmal structure turned out to be a pseudoaneurysm since the saccular wall contained only scar tissue but no myocardial cells. This is a very rare case of a patient with a left ventricular pseudoaneurysm who survived for 22 years after its occurrence.
