Which type of conduit to choose for right ventricular outflow tract reconstruction in patients below 1 year of age?

Abstract

Homografts, bovine jugular vein conduits and porcine-valved Dacron conduits exhibit equal durability after implantation in patients below 1 year of age independent of their size. Nonetheless, moderate conduit stenosis or insufficiency develops earlier in patients with a Contegra conduit. Conduit placement in the neonatal period and implantation in a heterotopic position shortens the durability.

Valved conduits in pediatric cardiac surgery

“…Последний при-обрел значительную популярность и по сей день исполь-зуется в большинстве хирургических центров [6,17]. Кро-ме того, были разработаны еще несколько ксенокондуи-тов, не применявшихся в столь же широких масштабах: LabCor, TissueMed, Bio-Cor и Shelhigh [18][19][20][21].…”

“…В последнее время появились сообщения о приемле-мых отдаленных результатах использования дакронового кондуита Hancock (Medtronic Inc., Minneapolis, MN) [13,21,27]. E. Belli и соавт.…”

“…K. Vitanova и соавт. [21] при сравнительной оценке кондуитов Hancock, Contegra и ал-лографтов выявили, что отсутствие стенозов через 5 лет составляет 69,1±7,9% для Hancock; 75,1±9,1% для Contegra и 85,4±5,6% для аллографтов. Недостаточность клапана кондуита составила 91,7±4% для аллографтов, 74,6±9,1% для Contegra, и 86,9±7,4% для Hancock в тече-ние 5 лет.…”

Smaller-Sized Expanded Polytetrafluoroethylene Conduits With a Fan-Shaped Valve and Bulging Sinuses for Right Ventricular Outflow Tract Reconstruction

“…It should also be noted that Albanesi and associates [15] reported finding that Contegra graft infection occurred in 11.3% of patients (12 of 106 cases). As of this writing, several studies have been undertaken to compare the different conduits [14,16,17]. Vitanova and coworkers [16] examined the reconstruction of the RVOT in patients younger than 1 year of age and reported on the durability of homografts and Contegra and Hancock conduits that were 15 mm or less in size.…”

Mid- to long-term outcomes of bovine jugular vein conduit implantation in Chinese children

“…Moreover, the BJV has been demonstrated to be associated with a better hemodynamic performance, lower rate of fibrocalcification, and lower antibody induction, compared to other xenografts and even homograft conduits (1)(2)(3). However, drawbacks of BJV conduits also have been noted, such as susceptibility to distal conduit stenosis; in addition, early valve incompetence and conduit thrombosis have been shown to be more prevalent in patients with BJV graft implantation (4,5). Therefore, conduit durability has been paid particular attention in Western countries; however, the relevant data and…”
