Figure 3: Case of 53-year-old man with LCX dominant and multivessel disease. CCTA revealed a >75% stenosis in the mid RCA, a >50% stenosis in the proximal LCX, a >75% stenosis in the obtuse marginal branch, and a >75% stenosis inthe mid LCX. Exercise-stress myocardial perfusion SPECT using 99mTc-tetrofosmin (non-AC images) showed partially reversible perfusion defects in the lateral and inferoposterior wall. On hybrid SPECT/CT, the lateral and inferoposterior ischemia was located in the LCX territory, while the RCA territory did not show any perfusion defects.
