[Cardiac Doppler in the selection of patients for aortic valvuloplasty. Comparison with data of phonomecanograms].
Between December 1986 and August 1987, 34 patients referred for aortic valvuloplasty, undergo before catheterization an ultrasonocardiography with continuous and pulsed Doppler study and a phonocardiography for 22 of them. They all present functional and physical signs of aortic stenosis. The cardiac Doppler enables a positive diagnosis in all patients, while the phonocardiography recordings fail to recognize a tight aortic stenosis. On the other hand, the Doppler enables a diagnosis of severity well correlated with the catheterization (r = 0.88 for maximum instantaneous gradients) in 30 patients: in four patients, the correlation could not be calculated because of technical problems related to the catheterization (2 patients) or the ultrasonic examination (2 patients). From this study, it results that the cardiac Doppler may perfectly select patients who are to undergo an aortic valvuloplasty, unlike phonocardiography.
