Question

Quizplus · Accepted Answer

Stents are currently the predominant form of percutaneous coronary intervention and are used in more than 90% of all interventional procedures.The Rotablator device has a high-speed, rotating, diamond-coated bur that drills through the plaque, creating tiny particles.Because directional coronary atherectomy extracts pieces of atheroma that can be studied microscopically (similar to a biopsy specimen), it has contributed significantly to our understanding of atherosclerosis and restenosis.Percutaneous transluminal coronary angioplasty (PTCA), frequently abbreviated to balloon angioplasty or simply angioplasty, was introduced in 1977 as an alternative to coronary surgical revascularization.PTCA avoided many of the risks associated with cardiac surgery (general anesthesia, sternotomy, extracorporeal circulation, and mechanical ventilation), but its success was hampered by complications related to the procedure (acute closure)and restenosis or renarrowing of the vessel after the procedure.
