The purpose of our study was to determine the distribution of pulmonary flow at rest and with exertion in total or partial by-pass of the right ventricle (TBP and PBP). During 1990–1994, 98 patients (p) were studied within their first post-operative year utilizing pulmonary scintigraphy with 99m TcMM. The radioactive agent was injected intravenously by superior(arm) and inferior (leg) routes in these patients with congenital cardiopathies consisting of a univentricular atrioventricular (AV) connection or other complex cardiopathies with pulmonary stenosis or previous pulmonary arterial banding unamendable to biventricular correction. Pulmonary perfusion was considered to be homogeneous with a right/left lung ratio of <60/40, right dominant with >80/20, and slightly right dominant with a 60–70/30–40 ratio. 10 p were further studied utilizing 99m Tc-MAA scintigraphy during maximal exertion (ergometric stress test). |
