Sudden death 10 years after patch aortoplasty for coarctation

Area of Science:

• Cardiovascular Surgery
• Medical Device Safety
• Aortic Aneurysm Research

Background:

• Coarctation of the aorta repair often involves prosthetic materials like Dacron patches.
• Long-term outcomes and potential complications of patch aortoplasty require ongoing investigation.
• Patient follow-up protocols after aortic repair need continuous evaluation.

Observation:

• A 25-year-old patient died from a ruptured aortic aneurysm 10 years after a Dacron patch repair for coarctation of the aorta.
• The aneurysm was unrecognized, and the patient had no signs of hypertension or residual obstruction post-surgery.
• The patient was discharged from regular cardiac unit follow-up to general practitioner care.

Findings:

• Patch aortoplasty for coarctation of the aorta carries a risk of late aneurysm formation and rupture.
• Aortic dilation at the repair site can occur even without hypertension or residual obstruction.
• Current follow-up may be insufficient for detecting delayed complications of aortic repair.

Implications:

• Lifelong cardiac surveillance with advanced imaging is essential for patients undergoing patch aortoplasty for coarctation of the aorta.
• Early detection of aortic dilation is critical for timely surgical intervention.
• This case highlights the importance of specialized, long-term follow-up in cardiac units for managing complex aortic conditions.
