Arms Assigned Interventions
Experimental: Bosentan group
Bosentan 2mg/kg/dose twice a day and routinely therapy in children with functional single ventricle during the period of staged Fontan procedure with high risk of increased PVR.
Drug: Bosentan
Bosentan 2mg/kg/dose twice a day and routinely therapy in children with functional single ventricle during the period of staged Fontan procedure with high risk of increased PVR.
Other Name: Tracleer
No Intervention: Routinely group
Routinely therapy in children with functional single ventricle during the period of staged Fontan procedure with high risk of increased PVR.

Detailed Description:

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.

  Eligibility

Ages Eligible for Study:   4 Months to 18 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Signed informed consent obtained from patient's legally acceptable representative.
  • Pediatric patients waiting for staged Fontan procedure with high risk of increased PVR after bidirectional cavopulmonary connection (BCPC)

    • Transpulmonary pressure gradiant (TPG) > 10mmHg when the obstruction of anastomosis and lung problem were excluded.
    • With the diagnosis of high risk of increased PVR, such as associated with TAPVC, after pulmonary artery banding, after systemic to pulmonary shunt more than 6 months, and et al.
    • Diagnosed as increased PVR with catheterization.

Exclusion Criteria:
