  Purpose

Hypoplastic left heart syndrome (HLHS) and related anomalies involved a single ventricle are characterized by hypoplasia of the left heart and the aorta with compromised systemic cardiac output. Infants with the syndrome generally undergo a staged surgical approach in view of an ultimate Fontan procedure. Although long-term survival in patients with HLHS and related single ventricle physiology has improved markedly with advances in medical and surgical therapies, a growing number of infants will ultimately require heart transplantation for end-stage heart failure due to several potential disadvantages include a negative effect on right ventricular function, arrhythmia, additional volume load via regurgitation from the nonvalved shunt, and impaired growth of the pulmonary artery.

Risk factors for poor outcome of heart transplantation with HLHS and single ventricle physiology are older age at transplantation and previous Fontan operation. New strategies are needed to improve the underlying transplant risks proper for the Fontan failure patients.

Emerging evidence suggests that heart-derived stem/progenitor cells can be used to improved cardiac function in patients with ischemic heart disease. In this trial, the investigators aimed to test the safety and feasibility of intracoronary injection of autologous cardiac progenitor cells in patients with HLHS and related single ventricle anomalies and that could improve ventricular function at 3 months' follow up.

Primary Outcome Measures:
  • A Phase I Study of the Safety and Feasibility of Transcoronary Infusion of Cardiac Progenitor Cells in Patients With Single Ventricle Physiology [ Time Frame: 3 months to 1 year after cell transplantation ] [ Designated as safety issue: Yes ]
    The primary end point is to monitor major adverse cardiac events include death, sustained/symptomatic ventricular tachycardia, aggravation of heart failure, new myocardial infarction, unplanned cardiovascular operation for cardiac tamponade and infection in the first month after injection, and serially afterwards.


Secondary Outcome Measures:
  • A Phase I Study of the Safety and Feasibility of Transcoronary Infusion of Cardiac Progenitor Cells in Patients With Single Ventricle Physiology [ Time Frame: 3 months to 1 year after cell transplantation ] [ Designated as safety issue: Yes ]
    Second end points include the rate of composite serious adverse events with death excluded and the rate of other complication.

Arms Assigned Interventions
Sham Comparator: Control
Subjects will undergo standard staged-procedures without cell infusion
Procedure: staged shunt procedure
Norwood-Glenn, Glenn, or Fontan procedure will be applied
Experimental: Cell infusion
Subjects will receive transcoronary infusion of autologous cardiosphere-derived cells 1 month after staged shunt procedure
Procedure: Autologous cardiac progenitor cell transplantation
Patients will receive 0.3 million / kg of autologous cardiac progenitor cells via intracoronary delivery 1 month after cardiac surgery. Follow-up visits 3 months to 1 year after cell injection will need to prospectively verify the clinical, laboratory, and safety-related data.
Other Name: Cardiosphere-derived cells
Procedure: staged shunt procedure
Norwood-Glenn, Glenn, or Fontan procedure will be applied

Detailed Description:

Autologous cardiac progenitor cells are isolated from patients' own cardiac tissues obtained during palliative shunt procedure. Patients will receive 0.3 million/kg of autologous cardiac progenitor cells via intracoronary delivery 1 month after cardiac surgery. Follow-up visits 3 months to 1 year after cell injection will need to prospectively verify the clinical, laboratory, and safety-related data.
