ABSTRACT
Changes in the mobility of the pulmonary valve were determined by a retrospective review of right ventricular cineangiograms from 25 balloon pulmonary valvotomy (BV) procedures in 23 infants and children. The angiographic changes were compared with the post-BV catheter and Doppler pressure gradients across the right ventricular outflow tract. Angiographic features felt to indicate valve tearing were present following 17 of 25 procedures and included increased excursion or straightening of leaflets, localized change in leaflet motion (flail leaflet), and the presence of an additional contrast jet through the valve. There was no statistically significant relationship between any of the angiographic parameters and the pressure data. Most patients with marked increase in angiographic valve mobility had low residual right ventricular to pulmonary artery gradients. However, the absence of angiographic change was not always associated with a high residual gradient.
