Pressure Recovery in Aortic Valve Stenosis Warren
نویسنده
چکیده
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 catheterization. Systematic catheter pullback from the left ventricular cavity revealed a consistent although variable subvalvular gradient. Further pullback across and distal to the region of the stenosed aortic valve revealed a consistent and progressive increase in the ascending aortic pressure. This increase in

Abstract Background: Balloon valvuloplasty uses for treatment of aortic stenosis from 20 years ago. Regarding loss of information about results of balloon valvuloplasty of hereditary aortic stenosis, this study was done to determine prognosis and complication of balloon valvuloplasty during last 10 years. Methods: This study was done on existing data of all children with hereditary aortic...
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 کاملStenosis is in the eye of the observer: impact of pressure recovery on assessing aortic valve area.
Severity of aortic stenosis. The study by Garcia et al. (1) in this issue of the Journal has bearing on a long-standing clinical quandary: Doppler continuity aortic valve areas (2,3), taken in the context of typical catheterization valve area cutoff values (4,5), often appear to produce misclassification toward higher degrees of severity, particularly in patients with relatively mild obstructio...
