The cutting balloon (CB)1 is a special balloon catheter with three or four atherotomes (microsurgical blades) bonded longitudinally to its surface, suitable for creating discrete longitudinal incisions in the atherosclerotic target coronary segment during balloon inflation. With the cutting balloon, the increase in the vessel lumen diameter is obtained in a more controlled fashion and with a lower balloon inflation pressure than conventional percutaneous transluminal coronary angioplasty (PTCA) - this controlled dilatation could reduce the extent of vessel wall injury and the incidence of restenosis.

The Global trial,2 a multicentre, randomised trial on 1,238 patients, tested the hypothesis that surgical dilatation using the CB (617 patients) could result in less arterial trauma, fewer dissections and less frequent restenosis than conventional PTCA (621 patients). The lesion selected in this stud...
