Small coronary vessels account for 40 to 50% of all coronary stenosis, and their revascularization is associated with high technical failure in CABG and increased risk of restenosis with PCI.
The term “small vessel” denotes a coronary artery with reference vessel diameter (RVD) < 2.8 to 3.0 mm.1 Lesions involving small vessels account for 40 to 50% of all coronary stenosis.2 Revascularization of these vessels is impeded by high technical failure in coronary artery bypass grafting (CABG) and increased risk of adverse events and restenosis with percutaneous coronary intervention (PCI). Intervention in small coronary vessels constitutes 30 to 50% of all intervention procedures performed worldwide every year.3 4 5
Lalita Nemani (Fri,) conducted a review in Small vessel coronary artery disease. Small vessel angioplasty was evaluated. Small coronary vessels account for 40 to 50% of all coronary stenosis, and their revascularization is associated with high technical failure in CABG and increased risk of restenosis with PCI.
