Background

Right ventricle-to-pulmonary artery reconstruction is essential in congenital heart surgery.

Methods

We analysed data from 2021 to 2023 regarding primary diagnoses, conduit types, and selection criteria.

n = 926 cases

Results

Used in 80.7% of cases, far more than bovine jugular vein or homograft conduits.

Handmade ePTFE valved

80.7%

Bovine jugular vein co

7.5%

Homografts

1.1%

More results

In Japan, cryopreserved homograft availability is limited, necessitating alternative materials.

Conclusion

A significant gap exists between current performance of conduits in general and clinical expectations for durability, underscoring the need for technological advancements in conduit design.
