[Heart transplantation : Current situation]

Area of Science:

• Cardiology and Transplant Surgery
• Immunology and Pharmacology

Context:

• Heart transplantation is the definitive treatment for end-stage heart failure.
• Donor organ scarcity necessitates regulated allocation and advanced preservation techniques.
• Surgical techniques and post-operative management are critical for successful outcomes.

Purpose:

• To provide an overview of heart transplantation as a treatment modality.
• To highlight challenges in donor heart availability and allocation.
• To discuss surgical techniques, preservation, and immunosuppression strategies.

Summary:

• Heart transplantation is the gold-standard for end-stage heart failure, but donor organ shortage is a major limitation.
• The Transplantation Act governs donor heart allocation based on urgency and success probability.
• Both biatrial and bicaval techniques are used for implantation, with the latter offering fewer complications. Mechanical perfusion extends transport viability.
• Post-transplant immunosuppression is essential for preventing rejection and ensuring long-term patient survival.

Impact:

• Informs clinical practice regarding heart transplant allocation and surgical options.
• Underscores the importance of immunosuppression in managing post-transplant complications.
• Highlights areas for future research in organ preservation and donor pool expansion.
