Current status and challenges of cardiac transplantation in the MENA region: A narrative review

Abstract

Introduction

Cardiac transplantation has progressed markedly since 1967, with advances in immunosuppression, surgical techniques, and postoperative care that improve outcomes. However, challenges persist in the Middle East and North Africa (MENA) region due to unique cultural, economic, and infrastructural barriers. This review explores the status, innovations, and challenges of cardiac transplantation within MENA countries, comparing outcomes with global standards.

Methodology

A comprehensive literature search was conducted across PubMed, Web of Science, and Cochrane databases, including studies from inception to May 2024. Search terms targeted heart transplantation practices, challenges, and innovations in the MENA region. Articles not in English, non-human studies, and duplicates were excluded. Data extraction focused on patient demographics, transplantation outcomes, and barriers specific to the MENA context.

Results

Cardiac transplantation in MENA has made strides, with established programs in Saudi Arabia, the UAE, and Lebanon. Innovations like ex-vivo perfusion and Left Ventricular Assist Devices (LVAD) are improving transplant outcomes, yet organ shortages remain critical. Cultural and religious beliefs influence donation rates, and infrastructure varies widely, with disparities in healthcare resources across countries. Key barriers include low donor registration, inconsistent brain death definitions, and limited public awareness. Economic and infrastructure limitations further complicate access to advanced transplantation techniques.

Conclusion

While cardiac transplantation has evolved in MENA, significant barriers hinder widespread adoption. Enhancing public awareness, developing regional networks, and implementing standardized protocols can improve outcomes. Targeted immunosuppressive therapies and continued innovation in organ preservation are essential to advance cardiac transplantation in MENA.
