Early and Late Changes in Left Ventricular Systolic Performance After Percutaneous Aortic Balloon Valvuloplasty David H. Harpole, MD, Charles J. Davidson, MD, Thomas N. Skelton, MD, Katherine B. Kisslo, RDMS, Robert H. Jones, MD, and Thomas M. Bashore, MD
To evaluate early and late hemodynamics after sortie valvuloplasty, 17 patients underwent firstpass radionuclide angi-rdiography with simultaneous high-fklelity micromanometer pressure before, 10 minutes after and 6 months after aortic valvuloplasty. Pressure-volume and stress data were assessed. Immediately after the procedure, no signifkxmt change was observed in heart rate, systemic bkuul pressure, cardiac output or aortic insufficiency (as measured by vfsual or quantitative aortography). The mean and peak transvalvular gradient decreased from 64 to 36 mm Hg (p
