    Abstract:
    BACKGROUND: Coronary artery involvement is not a rare presentation of Takayasu arteritis (TA) and the treatment is challenging. The optimal methods of revascularization, and prognosis of treatment have not been established. OBJECTIVES: To assess the long-term outcomes of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in TA patients. METHODS: Patients with coronary artery involved in TA who underwent either PCI or CABG were identified between February 2003 and December 2015. The primary outcome was long-term all-cause mortality. Secondary outcomes were myocardial infarction (MI), stroke, and repeat revascularization. RESULTS: Thirty-one patients were enrolled (PCI=19 vs. CABG=12). Most of them were female (25, 80.6%) and the mean age was 42.6±13.8years (16-64years). Angina pectoris was the most common initial symptom (26 cases, 83.9%) and concomitant aortic regurgitation was present in 8 (25.8%) patients. Both groups had a low rate of corticosteroids use [4/19 (21.1%) vs. 2/12 (16.7%)]. During the median follow-up of 101months (10-384months), PCI group had a significantly higher incidence of restenosis [12/19(63.2%) vs. 3/12(25%)]. Two patients with severe aortic regurgitation in PCI group suffered from cardiac death during follow-up. CONCLUSIONS: Coronary artery involvement should be suspected in TA patients with angina pectoris, especially young women. PCI had a very high rate of in-stent restenosis in patients without corticosteroids and CABG may be a preferred treatment option.
