Twelve neonates and infants with complex congenital cardiac disease underwent banding of the main pulmonary (MPA) artery. Postoperative evaluation included two-dimensional echocardiography (2-DE) and angiography to evaluate distal pulmonary artery (PA) morphology and pulmonary artery pressure. Determination of the ratio of PA diameter at the band to PA diameter at the annulus (PAB/PAA) by 2-DE (range 0.21-0.42, m=0.34) compared favorably to the same determination in patients studied by angiography (range 0.28-0.48, m = 0.37). When the degree of PA constriction by the band (PAB/PAA) was compared to the fall in distal PA pressure (peak systolic PA pressure/peak systolic arterial pressure) in a subgroup of eight patients with favorble pre-banding hemodynamics, good correlation was obtained, r=0.85. One patient developed aneurysmal dilatation of his PA which was noted on postoperative 2-DE study and confirmed by angiography. These data suggest that 2-DE plays an important role in the postoperative assessment of patients following pulmonary artery banding.
