Insights
Takayasu arteritis can affect coronary arteries, causing stenosis. A Y-graft arterial bypass on a beating heart effectively treated a young woman with severe coronary ostial and left main stenosis, relieving her angina.
Area of Science:
- Cardiology
- Vascular Surgery
- Rheumatology
Background:
- Takayasu arteritis rarely involves coronary arteries, with lesions found in 9-11% of cases.
- Coronary artery lesions typically manifest as ostial stenosis or occlusion.
Observation:
- A 19-year-old woman presented with crescendo angina.
- Diagnostic investigations revealed ostial and left main coronary arterial stenosis in a left-dominant circulation pattern.
Findings:
- Arterial Y-graft bypass surgery on a beating heart was performed.
- This approach provided superior myocardial perfusion compared to a single graft.
- It avoided anastomosis to an inflamed aorta and ensured long-term internal mammary artery graft patency.
Implications:
- Coronary artery bypass grafting is an effective treatment for Takayasu arteritis-induced coronary stenosis.
- The Y-graft technique offers advantages in complex cases involving aortic inflammation.
- Successful surgical intervention relieved angina and improved functional capacity in the patient.
Abstract:
Takayasu's arteritis with coronary artery involvement is rare, and there is little published information on the subject. Coronary angiographic and histopathologic studies have revealed coronary artery lesions in 9% to 11% of cases. Coronary artery involvement consists mostly of stenosis or occlusion of the coronary ostia. We report the case of a 19-year-old woman who presented with crescendo angina. Upon investigation, we found that our patient had ostial and left main coronary arterial stenosis with left-dominant circulation; therefore, we decided that an arterial Y graft, performed on a beating heart, would provide better perfusion to the compromised myocardium than would a single graft to the left anterior descending artery. In addition, use of the Y graft obviated the need to perform a proximal anastomosis on an inflamed, edematous ascending aorta, and it conferred long-term graft patency of the internal mammary arteries. Timely coronary artery bypass grafting relieved our patient's angina, and in early follow-up she has shown good effort tolerance.
