Eight patients with congenital pulmonary regurgitation documented by cardiac catheterization and angiography were studied by echocardiography. Echocardiographic features of the pulmonary valve observed in this condition included a) diastolic fluttering (5 cases), b) diastolic separation (2 cases), and c) increase of posterior motion during atrial systole (a wave). Maximum a wave depth exceeded the upper limit of the normal value in 2 cases and averaged 6.1 +/- 0.7 (standard error of the mean) mm. In addition, d) diastolic fluttering of the anterior tricuspid valve was seen in 5 cases and e) abnormal interventricular septal motion in 2 cases (one, paradoxical and the other, flat). Of these findings, the diastolic fluttering of the pulmonary valve, which results from the turbulent stream of blood in the outflow of the right ventricle striking the pulmonary valve, is pathognomonic for pulmonary regurgitation. Although the other findings are nonspecific, all patients had at least 1 of these 5 findings. Echocardiography, therefore, provides useful clues to the diagnosis of pulmonary regurgitation. Furthermore, echocardiography should be of use in differentiating congenital from functional pulmonary regurgitation and from aortic regurgitation.
