Fresh decellularized versus standard cryopreserved pulmonary allografts for right ventricular outflow tract reconstruction during the Ross procedure: a propensity-matched study.

Objectives: Recent studies have shown favourable early results with decellularized allografts (DAs) for right ventricular outflow tract reconstruction during the Ross procedure. However, mid- and long-term outcome data are still scarce. The objective of this study was to compare the durability of fresh DAs with standard cryopreserved allografts (SCAs) in patients undergoing the Ross procedure.
