Cardiac retransplantation: a 15-year single-center clinical experience

Area of Science:

• Cardiology
• Transplantation Medicine
• Immunology

Background:

• Cardiac retransplantation is a complex procedure due to donor heart scarcity.
• Outcomes of retransplantation are debated, necessitating further investigation.
• This study reviews short- and long-term results of cardiac retransplantation.

Purpose of the Study:

• To evaluate the short-term and long-term outcomes of cardiac retransplantation.
• To identify factors influencing survival after retransplantation.
• To compare outcomes based on indications for retransplantation.

Main Methods:

• Retrospective review of 28 cardiac retransplantation cases.
• Analysis of indications including primary graft failure (PGF), intractable acute cardiac rejection (IACR), and coronary allograft vasculopathy (CAV).
• Assessment of patient support methods (e.g., VAD, ECMO) and survival rates.

Main Results:

• Overall 1-, 5-, 10-, and 15-year survival rates were 46.4%, 40.6%, 32.5%, and 32.5%, respectively.
• Acute cardiac rejection was the leading cause of death (43.8%).
• Thirty-day and 1-year survival rates varied significantly by indication: IACR (50.0%/0%), PGF (63.6%/45.5%), and CAV (84.6%/68.4%).

Conclusions:

• Long-term survival is acceptable for patients with CAV and PGF.
• Patient selection is critical for retransplantation, especially for IACR cases.
• Careful consideration of indications is necessary to optimize outcomes in cardiac retransplantation.
