Transannular bovine jugular vein monocusp for the reconstruction of severe right ventricular outflow tract obstruction

ABSTRACT:

Objective

Severe right ventricular outflow tract obstruction in tetralogy of Fallot and variants necessitates the use of transannular patch in a significant proportion of children undergoing repair. We have used a Contegra monocusp together with delamination of native leaflet tissue in order to create a functioning pulmonary valve.

Methods

In total, 18 (2017-2022) consecutive Contegra monocusp implantations were included. Median age and weight were 3.65 [2.00; 9.43] months and 6.12 [4.30; 8.22] kg, respectively. Nine of 18 patients had undergone palliation. Native pulmonary leaflet tissue was recruited to create a single posterior cusp. Contegra monocusp selection was based on the goal to achieve a neoannulus of Z value ≈ 0. Monocusp sizes implanted were 16 [14; 18] mm. P
