The clinical, hemodynamic, and angiographic data on 92 patients with severe isolated aortic stenosis were reviewed to determine the incidence and mechanism of pulmonary hypertension. The status of each of these patients was determined 1 to 8 years after diagnosis by cardiac catheterization. Patients were divided into three groups on the basis of the(More)
Five patients seen with roentgenographic evidence of smooth, rounded mediastinal masses were evaluated by computerized tomographic (CT) scanning. Density readings from the lesion were interpreted in all patients as being equivalent to solid tissue. With these findings, thoracotomy seemed necessary for definitive diagnosis. All 5 lesions were found to be(More)
Thirty patients with 33 vascular injuries from blunt trauma to the brachiocephalic branches of the aortic arch are reported. To our knowledge, this is the largest series reported to date of blunt injuries to these vessels. Mechanisms of injury included deceleration, traction, and crush. Half of the injured vessels were the innominate artery, and a quarter(More)
Supraventricular arrhythmias continue to complicate the postoperative course of patients undergoing myocardial revascularization. In a previous study, we showed a decrease in arrhythmias if patients were given digitalis prior to operation. Since that time we have made two changes-- propranolol is no longer discontinued prior to operation and cold(More)
Intravenous leiomyomatosis involving the right side of the heart is an unusual cause of outflow obstruction. Evaluation of the patient should be directed not only at intracardiac chambers but also at the inferior vena cava. This should include angiography and MRI or CAT scanning. Echocardiography is an important contributory investigation. Surgical therapy(More)
A patient with primary osteogenic sarcoma of the left atrium with clinical features of severe congestive heart failure is described. The operative procedure required excision of the posterior atrial wall in continuity with the left pulmonary veins. The resultant defect in the atrium was reconstructed with the left atrial appendage. The left pulmonary artery(More)
The danger of irreversible ischemic damage to the spinal cord following repair of traumatic aortic rupture has prompted many techniques designed to decrease this risk. Surgical repair was performed on 41 consecutive patients, using four different methods. These included: group 1 (15 patients), left-heart pump bypass with systemic administration of heparin;(More)
Between 1972 and 1982, 9 patients underwent successful excision of atrial myxomas at the Upstate Medical Center. Eight patients had a left atrial myxoma and 1 a biatrial myxoma. There were 5 female and 4 male patients ranging from 16 to 63 years of age. Preoperative findings consisted of cerebral or peripheral emboli, congestive heart failure, and(More)
Between 1979 and 1986, 30 patients underwent replacement of the aortic valve and ascending aorta by a composite graft, with aortic wrapping of the graft. Thirteen patients had annuloaortic ectasia; six had DeBakey type I dissection (five acute, one chronic); three had DeBakey type II dissection (one acute, two chronic); three had left ventricular-aortic(More)
