Insights
This study presents a simultaneous hybrid approach for complex aortic arch aneurysm and coronary artery disease in a high-risk patient. This combined intervention offers a novel solution for managing multiple cardiovascular conditions concurrently.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Interventional Cardiology
Background:
- High-risk patients often present with complex cardiovascular conditions requiring tailored treatment strategies.
- Simultaneous repair of aortic aneurysms and coronary artery disease presents significant surgical challenges.
Abstract:
A 65-year-old gentleman with claudication underwent contrast-enhanced computed tomography. The scan showed occlusion of the infrarenal abdominal aorta and a 6.0 × 3.7 cm saccular zone-3 arch aneurysm. The left ventricular ejection fraction was 35% and a coronary angiogram revealed triple-vessel disease. In view of the patient's high risk with EuroSCORE II 20.34%, coronary artery surgery was combined with hybrid type I arch aneurysm repair. An endovascular stent was delivered in an antegrade manner. Open heart surgery and a hybrid type I arch intervention can be performed simultaneously through a midline sternotomy approach.
