Septal perforator compression (narrowing) in idiopathic hypertrophic subaortic stenosis.

Thirteen patients with idiopathic hypertrophic subaortic stenosis were compared with two groups of subjects: 10 patients with chest pain, normal coronary arteries and a normal left ventricle, and 10 patients with left ventricular hypertrophy. Five of the latter had aortic stenosis and five had idiopathic left ventricular hypertrophy. Coronary arteriography revealed that the septal branches of the left anterior descending artery closed or narrowed during systole in patients with idiopathic hypertrophic subaortic stenosis and did not do so in the other patient groups. This narrowing is possibly related to an abnormal position of the septal arteries within the septum in idiopathic hypertrophic subaortic stenosis. Systolic compression of the septal perforator arteries is not a pathognomonic sign of idiopathic hypertrophic subaortic stenosis.

Left ventricular myxoma: echocardiographic diagnosis and review of the literature.

A 33 year old man with the findings of mild aortic stenosis had an echocardiographic diagnosis of left ventricular myxoma prolapsing through the aortic valve during each ventricular systole. The M-mode echocardiogram, B-scan ultrasonogram and angiograms of this patient are presented. The clinical characteristics in all the reported cases of left ventricular myxomas are reviewed.

The normal electrocardiogram as a predictor of left ventricular function in patients with coronary artery disease.

Fifty-five consecutive patients with a normal resting electrocardiogram and coronary artery disease were examined to determine left ventricular function. Fifty-two (95%) had no evidence of left ventricular asynergy; 3 patients had only mild hypokinesis. Of this group of patients, 25 (47%) had one vessel disease, 17 (30%) had two vessel disease, and 13 (23%) had three vessel disease. Significant left ventricular asynergy was not found in patients with coronary artery disease and normal electrocardiograms. In addition, a normal electrocardiogram was not related to the number of coronary arteries involved.

Pericardial tumor of fibrosis mimicking pericardial effusion by echocardiography.

Echocardiograms of three patients with metastatic carcinoma or lymphoma showed a sonolucent space posterior to the left ventricular epicardium, as seen in pericardial effusion. However, at surgery or autopsy no pericardial fluid was found. Instead, the pericardium was infiltrated by neoplastic tissue or fibrosis. In view of this finding, we suggest caution in the interpretation of "positive" echocardiograms for pericardial effusion in patients with neoplastic disease, especially if pericardiocentesis is being considered.

Paradoxical motion of the interventricular septum with right ventricular dilatation in the absence of shunting: report of two cases.

A history, heart murmur, electrocardiogram and chest X-ray film suggesting an atrial septal defect associated with an echocardiogram revealing paradoxical motion of the interventricular septum with a dilated right ventricle may be considered indicative of a secundum or primum defect in a young adult or child. Two patients who fulfill all these criteria and had the presumptive diagnosis of an atrial septal defect were found at cardiac catheterization to have no demonstrable left to right shunt or other significant abnormality. The results of standard T-M mode echocardiograms were verified with B scan ultrasonograms. These cases may represent an early stage in the development of a cardiomyopathy. There is no echocardiogram pathognomonic of an atrial septal defect, and patients whose history and echocardiogram suggest this defect should have further diagnostic evaluation including technetium scan or cardiac catheterization.

Coronary artery dissection - a complication of cardiac catheterization without sequelae: case report and review of the literature.

This report describes an acute right coronary artery dissection occurring during diagnostic cardiac catheterization. Following catheter manipulation in the vicinity of the aortic valve, the patient complained of mild chest discomfort and had transient electrocardiographic evidence of acute inferior wall myocardial infarction with runs of 2:1 atrioventricular block. Within 5 min, the EKG reverted to precatheterization appearance, and the patient was asymptomatic. Coronary angiography revealed a dissection of the proximal vessel without obstruction. The patient had no clinical sequelae while monitored in the intensive care unit. The patient underwent elective aortic and mitral valve replacement. The area of the dissection was directly visualized, and no abnormality was noted. We review the literature of spontaneous and iatrogenic coronary artery dissections with regard to pathology, diagnosis, and prognosis, and make recommendations for therapy.

Myocardial infarction due to coronary atherosclerosis in three young adults with systemic lupus erythematosus.

Three patients, 24, 24 and 25 years of age, with systemic lupus erythematosus had signs of myocardial infarction. Two had serial electrocardiographic changes indicative of infarction without any cardiac symptoms. The third patient had clinical evidence of an acute massive myocardial infarction, which was proved at autopsy to be due to coronary atherosclerosis. This case is presented in detail and the association between systemic lupus erythematosus and myocardial infarction is reviewed. It is postulated that the relation between lupus erythematosus and coronary atherosclerosis is more than coincidental.

Transient Q waves in Prinzmetal's angina.

Transient abnormal Q waves were seen in two patients with Prinzmetal's angina during episodes of chest pain. The Q waves appeared recurrently while the patients had chest pain and disappeared when it subsided, indicating that Q waves suggestive of myocardial infarction can be seen with severe myocardial ischemia without actual necrosis. We describe these two patients, the various conditions in which transient abnormal Q waves have been reported and the theories offered to explain this electrophysiologic finding.

Disappearance of abnormal Q waves after aortocoronary bypass surgery.

Sixty-one patients were selected from 100 consecutive patients under-going aortocoronary artery bypass. The number of vessels diseased as defined by coronary arteriography and the number of bypass grafts were recorded. Review of the preoperative electrocardiograms showed an infarct pattern in 26 of the 61 patients and analysis of the postoperative electrocardiograms revealed loss of abnormal Q waves in 3 of the 26. The pre- and postoperative clinical course of these three patients is analyzed and the extent of their coronary artery disease and number of bypass grafts compared with those of the 23 patients who had persistence of the infarction pattern and the 17 patients who manifested new Q waves. Possible explanations for the disappearance of abnormal Q waves are discussed.

Bacterial endocarditis with ruptured sinus of Valsalva and aorticocardiac fistula.

A case is presented of bacterial endocarditis with a ruptured sinus of Valsalva and formation of an aorticocardiac fistula from the right coronary sinus into the right atrium and right ventricle. The pathologic, clinical and surgical aspects of bacterial endocarditis complicated by a ruptured sinus of Valsalva and an aorticocardiac fistula are analyzed. This complication of bacterial endocarditis is still uncommon, but alertness to its diagnosis makes possible early and successful surgical treatment.
