title: Percutaneous transluminal coronary angioplasty. Critical assessment of preliminary results.
abstract: Since June 1981 until July 1983, 40 percutaneous transluminal coronary angioplasty procedures in 38 patients have been performed. Results in the whole series are as follows: stenosis crossed in 33 patients (83%); balloon inflation done in 31 (78%), not done in 2 due to clinical instability induced by crossing of the stenosis; successful dilatation obtained in 25 patients (63%); emergency bypass surgery in 6 patients (15%) with 2 perioperative myocardial infarctions; no deaths. The whole series can be subdivided in two groups by the following parameters: premedication by nitrates (A) or by verapamil (B); temporal concentration of the procedures: 1/month up to February 83 (A), 3.7/month thereafter (B). Results are different in the two groups: 21 attempts in 21 patients: stenosis crossed in 14 cases (67%), balloon inflated in 12 (57%), successful dilatation obtained in 8 patients (38%), emergency bypass in 5 patients (24%). 19 attempts in 17 patients (2 vessel angioplasty in 2 patients): stenosis crossed and balloon inflated in 19 (100%), successful dilatation in 17 cases (89%), uncomplicated emergency bypass in 1 patient (5%). On the basis of personal more recent results an optimistic attitude towards the percutaneous transluminal coronary angioplasty is justified.
