Histological findings from “atherectomy” specimensthe histological evaluation of percutaneously removed plaques and perhaps the study of primary lesions and their restenoses will give further insight into this rapidly progressing atherosclerotic model.

What can we learn from classical operative techniques for valvular balloon dilatation?gery, and valvular balloon dilatation might have a lower mortality and morbidity rate, and repeat dilatations are thought to be easier to perform. In Table 1, an attempt is made to compare these postulated benefits with those of “classic” cardiac surgical techniques which, in general, provide well established and documented results.

Low-speed rotational angioplasty — clinical results in 53 patients with chronic occlusions8, 9, 11) can be reopened successfully only in about 50%–60% of cases. The chance of recanalization decreases with the duration of occlusion and the amount of calcification. The new technique called low speed rotational angioplasty (6, 14, 15) uses a very flexible, blunt, rotating catheter.

Advances in x-ray equipment — digital subtraction angiography with on-line quantificationThe most widely used way of quantification is quantitative angiography, but it must be born in mind that angiography shows only the lumen opacified by contrast medium, while characteristics of the vessel wall can hardly, if ever, be discerned (12, 18).
