Percutaneous transluminal coronary angioplasty (PTCA) is now capable of providing myocardial revascularization in a majority of patients, but significant problems with the technique remain. It is unsuitable for dealing with diffuse coronary artery disease, chronically occluded vessels may be impossible to disobliterate, and disease of the distal coronary vessel may be difficult to reach with a balloon. Approximately 5 percent of all procedures may be complicated by acute occlusion of the target vessel, usually by dissection of the arterial intima, often resulting in a need for emergency coronary artery bypass surgery (CABG). Furthermore, there is recurrence of the dilated lesion--'restenosis'--in approximately 30 percent of cases in the first 3 to 6 months after PTCA. Advances in this technique, since its introduction in the mid 1970s, have been directed at making initial success more likely, obviating the need for emergency CABG, and reducing the incidence of restenosis.
