Compared fate of small-diameter Contegras® and homografts in the pulmonary position

Abstract

In the first 4 years after pulmonary implantation of small-diameter Contegras and homografts, the fate of both conduits was statistically similar, in spite of different behavior. As Contegras is 'off-the-shelf' available, it constitutes a sound alternative to homograft for right ventricular outflow tract reconstruction in neonates and infants.

Comparison of bovine jugular vein with pulmonary homograft conduits in children less than 2 years of age☆

“…This is nearly identical to that reported by Sinzobahlmvya and associates in a series of 76 PHs ranging in size from 8 mm to 13 mm [19]. The 5-and 10-year freedom from dysfunction in the BJV cohort was significantly better at 90% and 85%, respectively.…”

Survival and reintervention after neonatal repair of truncus arteriosus with valved conduit

“…Contegra durability was lower, but the number of Contegras implanted is too small (n = 8) and the time of follow-up too short (maximum 29 months) to allow definitive conclusions. Nevertheless, results in this study were not as promising as recently reported by us [13] and by the aforementioned multi-institutional study [9]. It is to be noted that these two reports do not supply conduit survival beyond three postoperative years.…”

Common arterial trunk repair: with conduit or without?☆

“…The alternative to homograft implantation is represented by heterograft conduits. Despite that some case series using heterografts report good results on survival and freedom from re-intervention, [18][19][20] it is usually supported that heterografts have a higher rate of re-intervention compared to homografts [21]. Failure of heterografts is secondary to valve leaflet degeneration, sternal compression, intimal peel formation and calcification.…”
