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)
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)
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)
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)
We report a case of systemic embolization secondary to a small papillary endocardial fibroma, a rare cardiac tumor. It was attached to a chords of the mitral valve by a short stalk. The tumor was successfully excised and the mitral valve was preserved. Two-dimensional echocardiography played the major role in the diagnosis of this small endocardial tumor.
Pulmonary arterial hypertension in aortic stenosis (AS) is considered uncommon, and the possible mechanisms involved in its insorgence are only speculative. We analyzed a group of 95 patients with severe AS (mean systolic gradient greater than or equal to 50 mmHg and/or aortic valve area less than or equal to 0.7 cm2) studied by standard hemodynamic(More)
— We demonstrate an enterprise Dynamic Thresholding System for data-agnostic management of monitoring flows. The dynamic thresholding based on data historical behavior enables adaptive and more accurate control of business environments compared to static thresholding. We manifest the main blocks of a complex analytical engine that is implemented in VMware(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)
