Donor aortic dissection in a heart transplantation recipient

Area of Science:

• Cardiovascular Surgery
• Transplantation Medicine
• Aortic Disease

Background:

• Orthotopic heart transplantation (OHT) is a life-saving procedure for end-stage heart failure.
• Complications following OHT are well-documented, but aortic dissection remains exceptionally rare.
• Long-term surveillance and understanding of potential late complications are crucial in transplant recipients.

Observation:

• A patient developed a Type A aortic dissection 16 years after undergoing OHT.
• This delayed presentation of aortic dissection post-transplantation is unusual.
• The specific etiology and risk factors in this long-term post-transplant context require further investigation.

Findings:

• The case demonstrates that aortic dissection can manifest significantly late after OHT.
• Type A aortic dissection presents a critical surgical emergency, even in the context of prior transplantation.
• This report adds to the limited literature on aortic pathology in heart transplant recipients.

Implications:

• Clinicians should maintain a high index of suspicion for aortic pathology in long-term heart transplant survivors.
• Further research is needed to elucidate the mechanisms linking OHT and aortic dissection risk.
• Improved understanding may lead to enhanced screening protocols and management strategies for this unique patient population.
