Abstract
Doppler echocardiography and cardiac catheterization were undertaken in 70 consecutive patients, 31-68 years of age (mean 39), who had isolated congenital ventricular septal defects (VSD), 28 of whom had been operated upon. In 50 patients with invasively proven VSD, 37 had a correct Doppler diagnosis of VSD (group 1) and in 13 a false negative result was obtained (group 2); i.e. a sensitivity of 74%. No false positive Doppler diagnosis was made in the 20 patients without evidence of shunt. Left to right ventricular systolic pressure difference (
P) ranged between 55 and 142 mm Hg, with a mean value of 103 mm Hg in group 1 and 99 mm Hg in group 2. There was good correlation between
P obtained by continuous wave Dopier and catheterisation in 17 group 1 patients with moderate and large shunts (r=0.81, P<0.001). There was no correlation in the remaining 20 patients in group 1 with small shunts (r=0.20, P>0.l).
Doppler echocardiography in the adult with isolated VSD has good sensitivity and excellent specificity. Doppler prediction of
P is reasonably correct in patients with moderate and large shunts, but of no value in patients with small shunts.
