Simultaneous continuous-wave Doppler echocardiography and left- and right-sided cardiac pressure measurements were performed during cardiac catheterization in 64 patients with a congenital ventricular septal defect (VSD). The peak-to-peak pressure gradient across the VSD on cardiac catheterization ranged from 0 to 109 mm Hg (61 +/- 31.7 mm Hg). The peak shunt velocity and peak pressure gradient across the VSD on Doppler ultrasound imaging ranged from 0.96 to 5.21 m/sec (3.75 +/- 1.16 m/sec) and from 4 to 105 mm Hg (62 +/- 29.8 mm Hg), respectively. Doppler measurements of the peak interventricular pressure gradient correlated well with measurements obtained by cardiac catheterization (r = 0.98, standard error of estimate = 6.3 mm Hg, p less than 0.001). Doppler ultrasound imaging yielded information comparable to that obtained by catheterization and provided an accurate method of measuring the pressure gradient across the VSD, which is a useful parameter for the assessment of pulmonary artery systolic pressure in patients with a VSD, without a left or right ventricular outflow tract obstruction.
