Atrial septal aneurysms have been related (either by association or as potential causes) to systolic clicks, atrial arrhythmias, systemic and pulmonary embolism, atrioventricular valve prolapse and atrial septal defect. To study these associations and the incidence of atrial septal aneurysm, we reviewed 80 consecutive patients (female to male ratio 1.9:1,(More)
This study examines the recently reported gender differences in cardiac responses to exercise. The study group consisted of 192 men and 67 women with a low probability of coronary artery disease who underwent supine exercise radionuclide angiography. Men had a lower rest ejection fraction than that of women (0.63 versus 0.66, p = 0.02) and greater increases(More)
A patient was evaluated for a persistent pericardial effusion and on two-dimensional echocardiography was found to have an intracavitary left ventricular mass. Twenty-two years earlier, a melanoma of the ethmoid sinus had been excised. An electrocardiogram revealed impressive T-wave abnormalities and pathologic Q waves, initially suggestive of "myocardial(More)
Idiopathic retroperitoneal fibrosis and mediastinal fibrosis are localized expressions of a systemic sclerosing disease of unknown cause which, on rare occasions, may coexist in the same patient. Although pericardial involvement may occur, recurrent constrictive pericarditis that is unrelieved by pericardiectomy has not previously been reported in(More)
The indications for coronary angiography have been changing in recent years. To characterize these changes, we examined the records of Mayo Clinic patients referred for 400 coronary angiography procedures in 1973 and 1983 (200 procedures in each study year). We retrospectively assigned patients to one of seven general indication categories to determine the(More)
Pacemaker procedures performed at the Mayo Clinic for the years 1961, 1971, and 1981 were reviewed to examine the changes that have occurred in a large pacemaker practice during the 2 decades since the advent of pacemaker therapy. Major changes in trends and practice have occurred; in addition to numerical growth, the indications for permanent pacing and(More)
This study evaluated the recovery after exercise of both ST-segment depression on the exercise electrocardiogram (electrical evidence of ischemia) and exercise-induced abnormalities in wall motion or ejection fraction as detected by radionuclide angiography. The study group of 31 patients was selected to undergo prolonged electrocardiographic and(More)
Since 1980, use of the transseptal approach to catheterization of the left side of the heart has increased at our institution. In our experience, the transseptal technique has been used most commonly in adult patients with aortic stenosis, in whom the ease of access and the more reliable hemodynamics make it preferable to the retrograde approach.
