Summary
Abnormal coronary artery origins can complicate aortic valve repair. A modified aortic remodeling technique successfully treated a Marfan syndrome patient with adjacent coronary orifices, avoiding coronary translocation.
Area of Science:
- Cardiovascular Surgery
- Congenital Heart Disease
- Marfan Syndrome
Background:
- Aortic valve sparing procedures are complex, particularly with abnormal coronary arterial take-off.
- Marfan syndrome and annuloaortic ectasia present unique surgical challenges.
- Coronary artery anomalies can limit the feasibility of valve-sparing aortic root repair.
Observation:
- A 13-year-old patient with Marfan syndrome and annuloaortic ectasia had unusually positioned coronary artery origins.
- The patient's two coronary orifices were adjacent and located in the left coronary sinus, near the right-left commissure.
- This anatomical variation posed a significant risk during aortic valve surgery.
Findings:
- A modified aortic remodeling procedure was successfully employed.
- The surgical approach avoided the need for coronary artery translocation.
- The patient's aortic valve was spared, and coronary circulation was preserved.
Implications:
- This case demonstrates a successful modification of aortic remodeling for complex coronary anatomy.
- It highlights the possibility of performing aortic valve sparing surgery despite challenging coronary take-off variations.
- The findings suggest that innovative surgical techniques can improve outcomes in patients with connective tissue disorders and complex aortic root pathology.
