Atherectomy

Atherectomy is often part of a PTCA (angioplasty) procedure, but instead of compressing the plaque into the artery wall, as is done with Balloon Angioplasty, Atherectomy actually cuts away and removes fatty plaque to widen the artery and improve blood flow. A catheter is inserted ... (more...)
