title: Angioplasty in ulcerative coronary artery disease: acute results and early follow-up.
abstract: The safety and efficacy of percutaneous transluminal coronary angioplasty (PTCA) for stenoses involving ulcerative lesions were retrospectively studied. Seventy-seven patients (62 men and 15 women, mean age 62 +/- 10 years) representing 3.4% of 2,250 patients treated with PTCA during the period January 1, 1988 and June 30, 1990, had pre-PTCA stenoses defined as ulcerated. Twenty-eight (36%) of the stenoses were localized in the left anterior descending coronary artery, 9 (12%) in the left circumflex and 40 (52%) in the right coronary artery. During angioplasty, percent diameter stenosis was reduced from 73 +/- 14% to 22 +/- 13% and transstenotic gradient decreased from 48 +/- 18 to 12 +/- 6 mm Hg. Clinical success (freedom from angina at discharge without coronary bypass surgery, infarction or death) was achieved in 70 patients (90.9%). There were seven unsuccessful cases: three underwent elective coronary bypass surgery, one was managed medically, and three developed a major flow interrupting dissection during the procedure requiring emergency coronary bypass surgery. There were no deaths. At mean follow-up of 7.6 months, 45 of 61 patients (73.7%) remained asymptomatic. One patient needed an elective coronary bypass surgery and five patients had a successful repeat PTCA. In conclusion, PTCA for an ulcerated stenosis can be performed safely with a high primary success rate and a favorable early clinical course.
