. In balloon angioplasty a balloon-tipped catheter is inserted through the skin into a blood vessel and maneuvered to the clogged portion of the artery. There it is threaded into the blockage and inflated, compressing the plaque against the arterial walls. Frequent postoperative reclogging (restenosis) of the treated area has led to the use of alternative techniques such as laser angioplasty, which employs a laser to burn away or vaporize the plaque, and to the study of various drugs, gene therapies, and mechanical devices such as a stainless steel coil, or stent (most often now coated with a drug that inhibits restenosis), designed to hold the plaque back.

According to co-investigator Howard Herrmann, the rate of clinical success--defined as freedom from death, another heart attack, an urgent cardiac procedure, and bleeding--was 85% in the facilitated angioplasty group and 70% for other patients.
Unlike many treatments, facilitated angioplasty takes care of both clots and plaque," Ohman indicates.
In fact, there was a reduced need for blood transfusion and a trend toward less bleeding in patients who received facilitated angioplasty, Herrmann says.
