Abstract
|
|
|
Ross procedure is an ideal operative modality for diseased aortic valve especially I children, but homograft for right ventricular outflow tract(RVOT) reconstruction is not easily available in Korea. We tried to perform REV procedure for RVOT
reconstruction in 10 young piglets(15.3±1.3kg)in an attempt to exclude the use of homograft in Ross operation. 3 of them survived after operation and raised till adult pig(about 70%), then examined their pulmonary arteries and hearts. Without
any
stenotic residues in the great arteries, we only found the deformed monocusp patch with severe calcification, which deprived the adequate valve function, but kept the pig growing normally. We are sure that this operative modality (REV+Ross
procedure)
could be ext6endedly applied to the diseased human aortic valve, but we need to develop the anti-calcification method for the heterograft patch.
