Brief Summary

A single arm clinical trial evaluating the safety and efficacy of the second generation TEVG as vascular conduits for extracardiac total cavopulmonary connection.

Eligibility Criteria

Inclusion Criteria: * Patients will be eligible for inclusion in the study if they meet all of the following criteria. 1. Patient must be a candidate to undergo an extracardiac total cavopulmonary connection. 2. Patient and/or legal guardian must voluntarily provide informed consent/assent for participation in the study. Exclusion Criteria: * Patients will be excluded from participation in the study if they meet any of the following criteria. 1. Patient has an urgent/emergent operative status. 2. Patient has acute renal failure or renal insufficiency in the opinion of the investigator 3. Patient requires a graft less than 12 mm or greater than 24 mm in diameter. 4. Patient has a pacemaker. 5. Patient has pulmonary vascular resistance greater than 4 um2 (u=Wood's units) 6. Patient has abnormal venous drainage (interrupted inferior vena cava \[IVC\]). 7. Patient presents with significant atrio-ventricular valve regurgitation that in the opinion of the investigator, makes them ineligible. 8. Patient has a history of another condition or significant medical problem that, in the opinion of the investigator, precludes compliance with protocol-specified procedures. 9. Patients taking any medications that in the opinion of the Investigator could interfere with the TEVG, including bisphosphonates (i.e. Clodronate or Zoledronate). 10. Patient or parent/legal guardian is, in the opinion of the investigator, unable to comply with protocol evaluations. 11.
