Advancing Cardiac Care: A Registry of Heart Transplantation in Latin America (1968-2022)

Abstract

Introduction: Heart transplantation (HTx) has emerged as a pivotal intervention for end-stage heart failure, offering significant improvements in survival and quality of life. This manuscript elucidates the landscape of HTx across Latin America (LATAM) from its advent in 1968 through December 2022, shedding light on its evolution, current practices, and regional disparities.

Methods: We distributed a structured questionnaire to the national coordinators or representatives of the Interamerican Council of Heart Failure and Pulmonary Hypertension, collating responses from 20 LATAM nations. This approach facilitated a comprehensive aggregation of regional HTx data.

Results: A total of 12,374 HTx were performed in 166 centers across 16 LATAM countries, with Brazil, Argentina, and Colombia accounting for the majority of procedures. Pediatric transplants represented 9% of the total caseload, and combined organ transplants were reported in 62.5% of the participating countries, underscoring the complexity and breadth of transplant services in the region.

Conclusion: Despite facing infrastructural and logistical challenges, LATAM has demonstrated a robust capacity to conduct high-complexity transplant procedures. The establishment of a structured, regional HTx registry is imperative to enhance data collection and analysis, which in turn can inform clinical decision-making and policy development, ultimately improving patient outcomes across the continent.
