New option for balloon recanalization of total coronary occlusions.

In 9 out of 12 patients with a total coronary occlusion but definite signs of viable myocardium a new approach for the recanalization procedure was successfully employed: Following recanalization using an on-the-wire 2.0 or 2.5 mm angioplasty catheter, a standard coronary guidewire was placed along the angioplasty catheter. After withdrawal of the catheter, over-the-wire angioplasty with an appropriately sized balloon was performed for final dilatation. Pending further studies in a larger patient population, this new method may offer an alternative approach for revascularization of total coronary occlusions.
