Percutaneous transluminal revascularization of chronic total occlusion, coronary artery, coronary artery branch, or coronary artery bypass graft, any combination of intracoronary stent, atherectomy and angioplasty; single vessel

Percutaneous transluminal revascularization of a chronic total occlusion involves a minimally invasive procedure aimed at restoring blood flow in a coronary artery, a branch of a coronary artery, or a coronary artery bypass graft that has been completely blocked for an extended period. A chronic total occlusion is characterized by a blockage greater than 99% that has persisted for more than three months. This procedure utilizes various techniques, including angioplasty, atherectomy, and the placement of stents, to achieve revascularization. The approach typically begins with the preparation of the skin over the access artery, which is often one of the femoral arteries. A needle is used to puncture the artery, and a sheath is inserted to facilitate access. Under radiological guidance, a guidewire is navigated through the access site into the occluded artery or graft. If angioplasty is indicated, a balloon catheter is advanced to the blockage site, where it is inflated to compress plaque against the arterial wall, thereby widening the artery. Alternatively, atherectomy may be performed, which involves using a specialized catheter to shave away plaque from the artery. If necessary, an intravascular stent is deployed to maintain the artery's patency. Following the procedure, completion angiography is conducted to confirm the success of the revascularization, and appropriate post-procedure care is implemented to ensure patient safety and recovery.
