Coronary arterial narrowing in Takayasu's aortitis

Area of Science:

• Cardiovascular Medicine
• Rheumatology
• Immunology

Background:

• Takayasu's arteritis is a rare inflammatory condition affecting the aorta and its branches.
• Coronary artery involvement in Takayasu's arteritis can lead to significant ischemic heart disease.

Observation:

• A case of Takayasu's arteritis presenting with angina pectoris due to severe ostial coronary artery stenosis is detailed.
• The characteristic pathology involves adventitial thickening and inflammatory infiltrate extending into the coronary ostia.

Findings:

• Coronary artery narrowing results from intimal proliferation and fibrotic changes in the media and adventitia, mirroring aortic pathology.
• Distal coronary arteries are typically spared, maintaining normal caliber.

Implications:

• Angina pectoris can be the initial clinical manifestation of Takayasu's arteritis if coronary ostial stenosis is severe.
• Coronary artery bypass graft surgery offers an effective therapeutic option for managing coronary artery narrowing in this disease.
