Unusual intervention of native vessel in patient with coronary artery bypass

: Coronary artery bypass grafting (CABG) is older method of revascluarization treatment of coronary artery disease (CAD) then percutaneous coronary intervention (PCI), but in some cases, especially in multivessel disease or chronic total occlusions, still used. Extending survival of patients with CAD increases number of recathetrizations and interventions namely in post-CABG subjects. Due to degenerative and atherosclerotic changes of bypasses, especially venous grafts, interventional cardiologists are forced to solve often complicated findings. In other cases patients are reoperated with increased risk. Our task describes unusual, technically challenging and somewhat risk PCI of native vessel through arterial bypass in post-PCI patient with significant angina.
