- Abstract: A 43-year-old male presented with effort angina. Ammonia positron emission tomography (PET) revealed reversible perfusion defect in left anterior descending artery (LAD) and left circumflex artery (LCX) territories with decreased coronary flow reserve. Coronary angiogram showed significant stenosis in proximal LAD and intermediate diffuse stenosis in LCX and right coronary artery (RCA). Fractional flow reserve (FFR) showed similar results with ammonia PET. After percutaneous coronary intervention for LAD and LCX, flow and pressure checked by PET and FFR showed improvement. Simultaneously use of ammonia PET and FFR could be useful for determining ischemia-inducible lesion especially in diffuse intermediate lesion with discrepancy between functional studies.
