Abstract

When performing coronary angioplasty in patients with multivessel disease, there is an increasing trend to attempt balloon dilation of only ischaemia producing coronary stenoses (a strategy generally associated with incomplete revascularization) rather than attempting to dilate all anatomically significant stenoses (complete revascularization strategy). However the clinical efficacy of the former strategy has been questioned. To explore further this issue, we reviewed the records of 64 consecutive patients with multivessel coronary artery disease undergoing their first angioplasty at our centre in the 15 month period, October 1st 1987 to December 31st 1988. In 59 of these 64 patients, a strategy of incomplete revascularisation [attempted dilation of at least one stenosis > or = 70% but with one or more residual stenoses > or = 70% that were not attempted] was pursued. Of these 59 patients, 18 (31%) has three vessel coronary artery disease [stenoses > or = 70% in all three major coronary artery territories] and 19 (32%) had undergone previous coronary bypass surgery. In all 59 patients, prior to angioplasty, it was attempted to identify the ischaemia producing (so-called 'culprit') lesion(s). In the 59 patients, 66 culprit lesions in 63 vessels were identified. At angioplasty, in all patients, attempted dilation was confined to the culprit lesion(s). Clinical success (successful dilation of all attempted lesions without the occurrence of in-hospital myocardial infarction, death, or coronary bypass surgery) was achieved in 53 (90%) patients. At one year following successful angioplasty, no patient had died or suffered a myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)
