title: [Complex coronary angioplasty. I. Single or multiple dilatations in the involvement of several vessels in patients with coronary heart disease].
abstract: Coronary angioplasty was successfully performed in 658 of 752 multivessel disease patients. One lesion was attempted in 338 patients (45%), 2 or more in 414 patients (55%). Complications occurred in 39 patients (5.2%): 19 (2.5%) had a transmural infarction; 26 (3.5%) urgent surgery, and 14 (1.9%) died. Recurrence occurred in 233 (35%) of 658 patients with 162 (94.7%) of 171 having a successful 2nd angioplasty. Clinical improvement (followup: 31 months) remained in 81% of successful patients. Survival was not affected by the number of dilatations performed but was adversely affected by the presence of prior aorto-coronary bypass, surgery and ventricular dysfunction. Angioplasty can be an effective treatment without the need to dilate all vessels.
