Insights
Adults surviving arterial switch operations (ASO) need monitoring for coronary artery disease. Percutaneous coronary intervention is a viable treatment option for these complex cases, even decades later.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Adult Congenital Heart Disease
Background:
- Late coronary complications can arise after arterial switch operation (ASO) due to anatomical issues.
- Adult survivors of ASO often remain asymptomatic, necessitating proactive screening for coronary artery disease.
- Surgical management has been the primary approach for coronary artery disease post-ASO.
Observation:
- Complex aortic sinus anatomy and abnormal coronary origins in ASO patients pose challenges for percutaneous coronary intervention (PCI).
- Difficulties in catheter engagement and support are common during PCI in these patients.
- Multi-slice CT coronary angiography is crucial for pre-procedural planning and guidance.
Findings:
- This case demonstrates successful percutaneous coronary intervention in an adult patient with coronary artery disease 33 years after an ASO.
- PCI can be a feasible alternative to surgery for managing coronary artery disease in long-term ASO survivors.
- Careful pre-procedural planning using advanced imaging is essential for successful PCI in this population.
Implications:
- Highlights the importance of long-term surveillance for coronary artery disease in adult ASO survivors.
- Suggests that PCI, when carefully planned, is a valuable therapeutic option for complex coronary lesions in this unique patient group.
- Emphasizes the role of multi-slice CT coronary angiography in optimizing PCI outcomes for patients with congenital heart disease.
Abstract:
Late coronary complications after an arterial switch operation (ASO) may occur due to vessel kinking, compression resulting from growth of the great vessels, ostial fibro-intimal thickening after reimplantation or possibly secondary to accelerated atherosclerosis. Given that many of these patients are asymptomatic, adult ASO survivors require special attention and an individualised approach to the early detection of coronary artery disease. Most previously reported cases of coronary artery disease after an ASO have been managed surgically. Owing to the complex anatomy of the aortic sinuses and abnormal coronary origin, percutaneous coronary intervention may be challenging with difficult catheter engagement and/or support. Pre-procedural multi-slice CT coronary angiography can be used for proper planning and guidance. A case is described here for percutaneous coronary intervention in an adult patient who presented with coronary artery disease 33 years after an ASO.
