Summary

The results are presented of 44 systematic cardiac catheterizations in 35 patients after successful repair of various types of congenital cyanotic heart disease using a conduit.The operations were performed from 1972 to 1981. The patients were followed from 6 months to 9 years, the mean interval between operation and catheterization was 2.5 years (4 weeks to 8 years). Different types of conduits were used: a Hancock conduit in 27 cases (1 replaced), an aortic homograft in 3 cases (all 3 replaced by a Hancock conduit), a Dacron tube with Lillehei-Kaster valve in 2 cases (1 replaced), a lonescuShiley conduit in 5 cases, a composite graft of pericardium and a Hancock valve in one patient (replaced) and a valveless Dacron tube in one patient. The total conduit gradient was differentiated in 43/44 investigations. For the Hancock conduit the mean proximal gradient was 9 mmHg, the valvular 14 and the distal 13 mmHg. Severe valvular Stenosis of the porcine valve occurred in 3 patients. For the lonescu-Shiley conduit only early, but promising, results are available. Three of the 35 patients died late (2.5 and 4 years postoperatively); the deaths were related to severe additional lesions. Cross-sectional echocardiography was performed in 32 of the 35 patients. The latter does not appear to be a reliable method for the detection of valvular lesions so far, but is helpful for the diagnosis of proximal and distal obstructions of the conduit.
