Pressure Recovery in Aortic Valve Stenosis Warren
Background Pressure recovery is the variable increase in lateral pressure downstream from a stenotic orifice. The magnitude and clinical significance of pressure recovery in aortic valve stenosis are poorly defined. Methods and Results We obtained high-fidelity pressure and velocity recordings in 11 patients with isolated significant aortic valve stenosis at the time of diagnostic cardiac cathe...

متن کاملExtent, determinants and clinical importance of pressure recovery in patients with aortic valve stenosis.
AIMS In experimental studies the recovery of pressure distal to stenotic valve orifices has been well described. We evaluated the extent, determinants, and clinical importance of pressure recovery in patients with aortic valve stenosis. METHODS AND RESULTS The study was performed in 37 patients with aortic valve stenosis, in whom cardiac catheterization was performed and left ventricular and ...
متن کامل[The pressure recovery phenomenon in an interventricular septal defect with a high pressure gradient].
In patients with ventricular septal defect (VSD), estimating the ventricular gradient using a Doppler EKG is the normal method of measuring pressure within the right ventricle.1 However, cases of discrepancies between the pressure gradients taken using Doppler and hemodynamic studies have been reported, which is attributed to asynchrony in the pressure peaks of both ventricles.2 Another cause o...
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...
