Bosentan Therapy in Children With Functional Single Ventricle
Bosentan Therapy for High Risk Staged Fontan Procedure in Children With Functional Single Ventricle
Bosentan is a kind of dual endothelin receptor antagonist.The purpose of this study is to investigate if Bosentan therapy can modify the outcome of children with functional single ventricle.
Increased pulmonary vascular resistance (PVR) is a serous issues in children with functional single ventricle during the staged operative period. The purpose of this study is to investigate if Bosentan therapy can improve the survival and life quality after staged Fontan procedure in the children with high risk of increased PVR.
