Impact of right ventricle to pulmonary artery conduit on outcome of the modified norwood procedure

Síndrome da hipoplasia do coração esquerdo: a influência da estratégia cirúrgica nos resultados

“…Studies that showed lack of impact on survival in relation to the type of conduit analyzed very small newborn populations, in addition to comparing non-contemporary groups 24,25 . Patients with the RV-PA conduit had higher mortality rates and indication for transplant after the second palliation stage.…”

Follow-up study of pulmonary artery configuration in hypoplastic left heart syndrome

“…Adoption of the RV-PA shunt as an alternative to the conventional BT shunt has contributed to stabilizing the postoperative course as well as the results of the Norwood procedure. 6,18 Although the RV-PA shunt seems to provide larger, more symmetrical distal branch PAs than the BT shunt, 19,20 a more frequent occurrence of post-Norwood central PS has been reported. 4,5 Griselli and colleagues, with their large series of Norwood operations, reported that 27% of all patients required PA patch plasty at stage II palliation; notably, most of the patients with an RV-PA shunt required subsequent PA patch augmentation.…”

“…Moreover, other reports showing improved survival rates using the RV-PA tube utilized the history of patients with mBT as the control series [10,11,24]. Studies that proved that there is no impact on the survival rate in respect to the type of tube used, apart from comparing non-concurrent groups, had very small populations of newborns [25,26]. Patients with the RV-PA tube presented greater mortality and indication for transplant after the second stage.…”
