The patients were divided into three groups according topreoperative diagnosis: RVOT obstructions with ventriculo- arterial (VA)concordance (61), RVOT obstructions with VA discordance (18) and truncusarteriosus (11). Of the reconstructions, 52% were reoperations. A pulmonaryhomograft was used by preference (85% in the concordant group and 33% inthe discordant group). One patient died after homograft correction(hospital mortality 1.1%). The mean follow- up was 32 +/- 22 months. Onepatient died after 10 months due to congestive heart failure andobstructive pulmonary hypertension. All other patients were in NYHA classesI-II. Three patients (two discordant and one truncus correction) underwentreoperation because of aortic homograft dysfunction and calcification. Theincidence of significant (> or = 40 mmHg) gradient across thereconstruction found at the last echocardiographic control was 4% in theconcordant, 28% in the discordant, and 18% in the truncus, group.Echocardiographic evidence of moderate (grade 2-3/4) pulmonaryregurgitation (PR) was noticed in 24 and 13% of the concordant anddiscordant groups, respectively. From this medium-term experience it isconcluded that (1) the medium-term performance of cryopreserved homograftsis excellent, even in young patients, (2) corrections in patients with VAdiscordance need close follow-up, (3) the use of pulmonary homografts,especially in VA concordant lesions, should be encouraged, (4) longer-termfollow- up is necessary to confirm the superiority of the cryopreservedhomograft when compared to the porcine xenograft in the RVOT.
