TORCH-LATAM-003: Regional Advanced-Therapy Pathways for Congenital Heart Disease (TORCH-003)
A Stepped-Wedge Cluster Randomized Trial of the TORCH Congenital Advanced Therapies Pathway for Children and Adults With Congenital Heart Disease in Latin America
TORCH-LATAM-003 is a pragmatic stepped-wedge cluster randomized trial evaluating a regional pathway for children and adults with congenital heart disease and advanced cardiac and/or respiratory failure who may require heart, lung, or heart-lung transplantation, mechanical circulatory or extracorporeal support, or another regulated advanced-therapy pathway. Clusters transition from usual local pathways to TORCH-CATP. The primary outcome is completion of the prespecified multidisciplinary evaluation and documentation of an advanced-pathway decision within 90 days after enrollment. The study also evaluates barriers, authorized pathway or waiting-list activation, longitudinal status, advanced support, definitive therapy, and clinical outcomes. Donor-organ and matching events are captured only where legally authorized and do not replace national allocation systems or transplant-center decisions.

Detailed Description
Each TORCH regional network cluster is anchored in an authorized advanced-therapy or transplant center and may include activated evaluation, referral, congenital cardiology, pulmonary hypertension, intensive-care, mechanical-support, donor-origin, procurement, preservation, logistics, and data-coordination nodes. Children and adults with congenital heart disease may be identified at transplanting or non-transplanting centers when an authorized route to specialized evaluation exists. Authorized centers and competent authorities retain all legal and clinical authority for candidacy, waiting-list activation, organ acceptance, allocation, and transplantation.
The recipient pathway records identification, referral, enrollment, completion of multidisciplinary congenital evaluation, a documented advanced-pathway decision, barrier management, activation of an authorized pathway or official waiting list, longitudinal clinical and support status, transplantation, regulated external-protocol enrollment, or an alternative outcome. Study enrollment is analytically distinct from advanced-therapy candidacy and official wait-list status.
The pathway permits clinically documented redirection among heart, lung, heart-lung, or other authorized transplant evaluation; temporary or durable mechanical support; recovery; surveillance; palliative care; and independently governed investigational protocols. TORCH does not assign an investigational therapy, device, cell, organoid, or xenograft and does not infer efficacy or safety for such products.
Where legally authorized, donor-organ and recipient pathways converge at traceable compatibility and offer episodes. Each decision, non-acceptance reason, reassignment, urgency change, distance, logistics constraint, and final disposition is time-stamped. TORCH does not create a supranational allocation authority or override governmental or institutional systems.
Interoperability may range from audited manual transfer to structured documents, batch exchange, application programming interfaces, standards-based exchange, or validated remote-monitoring devices. Cross-border activity is activated only after applicable ethical, regulatory, institutional, data-protection, financial, and operational approvals.

Description
Inclusion Criteria:

- Ability to complete protocol-defined follow-up directly or through an authorized network pathway.
- Provision of informed consent by the participant or legally authorized representative, and assent when applicable, according to local requirements.
Exclusion Criteria:
- Absence of congenital heart disease as the underlying condition defining the advanced cardiac and/or respiratory-failure pathway.
- No authorized route for protocol evaluation or follow-up at the time of enrollment.
- Unable or unwilling to provide informed consent or legally authorized permission when required.
- The prespecified multidisciplinary evaluation and advanced-pathway decision were already completed and remain clinically current before enrollment.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: TORCH-CATP Intervention Period
Participants enrolled while their cluster is assigned to the intervention period receive the TORCH Congenital Advanced Therapies Pathway, including protocolized identification and referral, multidisciplinary evaluation, pathway-decision adjudication, barrier navigation, pathway and waiting-list status tracking, and traceable donor-organ opportunity coordination when applicable. |
A multicomponent health-services pathway that standardizes identification, referral, multidisciplinary congenital-heart-disease evaluation, advanced-pathway decision documentation, barrier navigation, longitudinal waiting-list and support status, authorized donor-organ and matching traceability, and secure information exchange. It does not assign organs, authorize therapies, or replace transplant-center or governmental decisions. |
|
No Intervention: Usual Local Pathway Period
Participants enrolled before their cluster transitions to TORCH-CATP receive locally available referral, evaluation, treatment, support, and transplant-candidacy processes. Study data collection does not alter the authority of local programs or competent authorities. |

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Completion of Multidisciplinary Congenital Advanced-Therapy Evaluation and Documented Pathway Decision Within 90 Days
Time Frame: Within 90 days after enrollment.
|
Percentage of eligible enrolled participants who complete the prespecified multidisciplinary congenital advanced-therapy evaluation and have a documented advanced-pathway decision within 90 days after enrollment. APD-A, APD-B, APD-D, APD-E, APD-F, APD-G, and APD-H count as completed decisions when the minimum evaluation is complete. APD-C denotes incomplete evaluation and is not counted as success. Death, irreversible deterioration, or missing evidence before day 90 is not counted as success unless the minimum evaluation and a valid decision were documented. |
Within 90 days after enrollment.
