Our experience with percutaneous transluminal coronary angioplasty--two years follow-up study.
The results of 130 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures carried out in 112 patients between November, 1986 and October, 1988 are reported. The follow-up period ranged from 1 month to 24 months. Eighty-four patients (75%) had single vessel disease, and 28 (25%) had multivessel disease. Two-vessel dilatation was done in 23 patients. The primary success rate was 92%. In successful cases, the diameter of stenosis was changed on an average from an initial 85% to 23%. Acute occlusion of the vessel occurred on 9 occasions (6.8%). Emergency coronary bypass surgery (CABG) was done in 3 (2.7%), 2 patients (1.8%) were subjected to immediate re-dilatation. One patient who underwent CABG died (case fatality 0.8%). Occlusion of the dilated vessels did not occur after the patients were discharged from hospital. Follow-up data revealed that long-term clinical success (class I status) was seen in 78 patients who had a successful primary dilatation. Of the 25 patients who were studied by a repeat coronary arteriography, 7 had developed restenosis. Five of these patients have been successfully redilated. It is concluded that PTCA is an effective and safe method of treatment in selected patients with coronary artery disease in our setting.
