ECHOCARDIOGRAPHIC ABNORMALITIES OF THE MITRAL VALVE ASSOCIATED WITH A LARGE PERICARDIAL EFFUSION.

Features of mitral stenosis and systolic anterior motion of the mitral valve were observed on the echocardiogram of a patient with a large posterior pericardial effusion. The abnormal findings disappeared with resolution of the fluid. Because pericardial effusion may result in the echocardiographic alteration of cardiac structures, repeat study is necessary after the effusion has cleared.

NEGATIVE TREADMILL EXERCISE TEST RESULT WITH SUBSEQUENT MYOCARDIAL INFARCTION AND CORONARY ARTERY BYPASS: CASE REPORT.

Myocardial infarction is a rare complication of maximal exercise testing.(1) In the case presented here, infarction occurred in a 54-year-old man, 14 minutes after he showed a normal response to maximal multistage treadmill exercise testing. The presence of coronary artery disease had been documented angiographically prior to exercise testing. After infarction, the patient underwent emergency double aortocoronary bypass to the left anterior descending and right coronary arteries with good results. Clinical evidence suggests that the extent of myocardial necrosis was reduced by timely surgical intervention. There is no conclusive explanation for this patient's normal response to maximal exercise testing in the presence of advanced coronary artery occlusive disease followed rapidly by infarction. The value of exercise testing is well established in assessing the existence or severity of coronary artery disease; a normal response, however, cannot be used as an infallible indication that critical coronary artery disease does not exist.

DISCRETE MEMBRANOUS SUBAORTIC STENOSIS: POSTOPERATIVE REVERSION OF AORTIC VALVE ECHOCARDIOGRAM TO NORMAL.

Clinical, hemodynamic, angiographic and echocardiographic findings in a patient with discrete membranous subaortic stenosis are presented. Echocardiography revealed evidence of a normal mitral valve and abnormal movement of the aortic valve with poor motion and fluttering of the anterior cusp. After a subvalvular membrane subjacent to the aortic valve cusp was excised, postoperative echocardiographic study showed normal movement of the aortic valve.

HEMIAZYGOS CONTINUATION TO CORONARY SINUS WITH NORMAL LEFT INNOMINATE VEIN.

A case is described of absent hepatic segment of the inferior vena cava with hemiazygos continuation and drainage into the coronary sinus with associated atrial septal defect and patent ductus arteriosus. In all previously reported cases of inferior vena caval anomalies with persistent hemiazygos, the hemiazygos joined the homolateral superior vena cava. To our knowledge this is the first case to be reported of a patient who had hemiazygos continuation to the coronary sinus with a normal left innominate vein and a single right superior vena cava.

SEGMENTAL AORTITIS AND AORTIC INCOMPETENCE.

An unusual case of a middle-aged male with segmental aortitis and aortic incompetence is described. To our knowledge, only 13 cases have been previously described in the literature, but only two have had anatomopathological confirmation. Aortic incompetence is a rare manifestation of segmental aortitis. Although intrinsic abnormalities of the aortic valve have been proposed, the finding of a normal aortic valve at postmortem examination in 2 of the 3 cases in which the aortic valve was examined, supports the premise that the incompetence is probably secondary to disproportionate dilatation of the aortic root.
