The primary objective of our study is to contribute to the scarce body of literature on the mid-term durability and hemodynamics of the INSPIRIS Resilia (model 11500) bioprosthesis when implanted in the pulmonary position in children and young adults. Investigators also aim to identify: effect of age on SVD, freedom from SVD, pathology of SVD, valve-related complications, freedom from re-operation, and survival rate.
