Abstract/OtherAbstract:
|
Directional coronary atherectomy (DCA) has received increased attention, especially as a bail-out procedure after failed balloon angioplasty. However, this technique may also be burdened by severe pitfalls. We report a patient with a balloon-resistant left coronary artery lesion subsequently treated with DCA. Despite its over-the-wire guidance, as the rotating cutter was advanced, it deviated from its intra-housing course and intruded into the vascular wall. Dislocation of the rotating blade was due to pressure from hard plaque tissue. After having carefully pulled back the complete catheter system, a severe spasm of the left main stem occurred, which was reversed by intracoronary nitroglycerine. The final angiography showed a left coronary artery without significant, residual stenosis. The case report underscores that DCA passes must be performed under continuous fluoroscopic control, especially for balloon-resistant lesions because of the unpredictability of DCA-imminent complication. |
