Simultaneous double balloon coronary angioplasty through a single guiding catheter for bifurcation lesions.

To enhance the safety, efficacy and expediency of coronary bifurcation lesion angioplasty, we report the use of two dilatation catheters, advanced simultaneously through a single guide catheter in three patients. Successful dilatation was performed in each. The technique involves the use of either two new low-profile dilatation catheters in an 8 French large lumen guide catheter or a single new low-profile dilatation catheter coupled with a conventional over-the-wire catheter within a new large lumen 9 French guide.
