Preoperative mortality in aortic stenosis.
Of I35 patients investigated for severe aortic stenosis, I6 died while awaiting surgery. The catheterization data on these patients were compared with those on .55 patients who underwent surgery and were long-term survivors and 42 who died at operation or during the early postoperative period. Of the I6 patients who died before operation, 15 had evidence of left ventricular failure. In addition...
متن کاملPreoperative diagnosis of carotid artery stenosis: accuracy of noninvasive testing.
BACKGROUND AND PURPOSE Carotid endarterectomy has been shown to be beneficial in symptomatic patients with a severe stenosis (70% to 99%) of the internal carotid artery (ICA). Digital subtraction angiography (DSA) is the standard of reference in the diagnosis of carotid artery stenosis but has a relatively high complication rate. In a diagnostic study we investigated the accuracy of noninvasive...
متن کاملNoninvasive assessment of valve area in patients with aortic stenosis.
A noninvasive method for quantification of aortic orifice area in patients with aortic stenosis is presented and compared with cardiac catheterization data in 24 patients (mean age 67 years). A continuous wave 2 MHz Doppler ultrasound instrument was used to measure the maximal velocity of the aortic jet, and time-averaged pressure drop was obtained by planimetry from the maximal velocity spectr...
متن کاملComprehensive evaluation of preoperative patients with aortic valve stenosis: usefulness of cardiac multidetector computed tomography.
BACKGROUND Preoperative assessment of patients with aortic valve stenosis (AS) relies on the evaluation of AS severity (aortic valve area, AVA) and left ventricular ejection fraction (LVEF) by echocardiography, and of coronary artery anatomy by coronary angiography. AIM To evaluate the feasibility and accuracy of contrast-enhanced multidetector computed tomography (MDCT), as a single non-inva...
متن کاملSUPRAVALVAR AORTIC STENOSIS IN CHILDREN REPORT OF THIRTEEN CASES
During 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of Shahid Rajai Heart Hospital, Tehran. All patients were subjected to cardiac catheterization and a angiocardiography. Patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. Seventy seven percent of childen were male. Eight cases (61.5%) had Wil...
