Abstract:
Marfan syndrome is associated with a high incidence of aortic root aneurysm and life-threatening aortic dissection. With the successful use of surgical aortic root replacement, dissection-related mortality has been significantly reduced. We present the case of a patient with Marfan syndrome who presented with heart failure secondary to an unusual graft-related complication 14 years after a Bentall procedure. Investigations revealed a supra-aortic stenosis resulting from a kink in the Bentall graft caused by pressure from an expanding aortic arch aneurysm. The patient underwent surgery with improvement in his ejection fraction and heart failure symptoms.
Insights
Marfan syndrome patients may develop graft complications years after aortic repair. This case highlights supra-aortic stenosis from a kinked Bentall graft, requiring surgical correction for improved heart function.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Medical Genetics
Background:
- Marfan syndrome frequently causes aortic root aneurysms and dissection.
- Surgical aortic root replacement has improved survival rates for these patients.
Observation:
- A patient with Marfan syndrome experienced heart failure 14 years post-Bentall procedure.
- Investigations revealed supra-aortic stenosis due to a kinked Bentall graft.
Findings:
- The graft kink was caused by an expanding aortic arch aneurysm.
- Surgical intervention led to improved ejection fraction and heart failure symptoms.
Implications:
- This case underscores the potential for late graft-related complications after aortic root surgery in Marfan syndrome.
- Long-term surveillance for aortic complications is crucial in these patients.
- Understanding graft-aneurysm interactions is vital for surgical planning.
