A 71-year-old woman was referred to our hospital for mitral valve repair and coronary artery bypass grafting (CABG). Conventional coronary artery angiography showed stenosis in the right coronary artery (RCA) and two diagonal branches, whereas transthoracic echocardiography (TTE) showed diffuse hypokinesis and mild-to-moderate mitral valve regurgitation. Fractional flow reserve derived from computed tomography (FFRct) demonstrated two additional lesions in the coronary artery at the left anterior descending artery (LAD) and the high lateral (HL) branch. Thus, we decided to perform CABG to RCA, LAD, the second diagonal branch, and HL as well as mitral valve repair. TTE one year after surgery showed trivial mitral regurgitation and progressive improvements in the left ventricular wall motion and the ejection fraction. FFRct is a usuful non-invasive method to identify coronary lesions that cause ischemia.
