Key result
Bovine jugular vein grafts showed comparable durability to aortic homografts and porcine-valved conduits for RV-PA reconstruction, with 10-year freedom from graft-related events of 52% vs 36%.
Why the study?
The optimal conduit for right ventricle to pulmonary artery reconstruction does not exist, and reinterventions caused by stenosis and endocarditis are common.
Does conduit type (bovine jugular vein, aortic homograft, or porcine-valved) affect the risk of graft-related events in patients undergoing RV-PA reconstruction?
Population
155 patients undergoing 193 RV-PA conduit implantation procedures
Comparison
Bovine jugular vein grafts vs aortic homografts vs porcine-valved conduits
Design
Retrospective cohort study

Comparable durability across conduits supports flexible selection in RV-PA reconstruction; leaves open need for randomized trials to guide choice.

Does conduit type (bovine jugular vein, aortic homograft, or porcine-valved) affect the risk of graft-related events in patients undergoing RV-PA reconstruction?
Absolute Event Rate: 52% vs 36%
In patients undergoing RV-PA reconstruction, durability and graft-related events are comparable among bovine jugular vein grafts, aortic homografts, and porcine-valved conduits, though reinterventions remain common.
Helal et al. (2024) conducted a cohort in Right ventricle to pulmonary artery (RV-PA) reconstruction (n=155). Bovine jugular vein conduit vs. Aortic homograft and porcine-valved conduits was evaluated on Graft-related events (infective endocarditis, transcatheter pulmonary valve replacement, transcatheter conduit dilatation, surgical conduit replacement, and transcatheter pulmonary branch intervention). Bovine jugular vein grafts showed comparable durability to aortic homografts and porcine-valved conduits for RV-PA reconstruction, with 10-year freedom from graft-related events of 52% vs 36%.
