Description: Endovascular procedure in which atheromatous plaque is excised by a cutting or rotating catheter. It differs from balloon and laser angioplasty procedures which enlarge vessels by dilation but frequently do not remove much plaque. If the plaque is removed by surgical excision under general anesthesia rather than by an endovascular procedure through a catheter, it is called ENDARTERECTOMY.

1.	Pathologic Constriction (Stenosis) 02/01/1997 - "The authors conclude: 1) that optimal atherectomy is associated with acceptable restenosis rates in selected vessels, 2) that short stenoses of large diameter arteries may be a privileged indication of the technique if the best results are obtained." 09/01/2006 - "RESULTS: Of 30 patients enrolled with significant LAD or LCX ostium stenosis, 29 were effectively treated with directional atherectomy (96.7% procedural success)" 06/01/1993 - "Atherectomy seems to be particularly beneficial in the treatment of eccentric and complex stenoses and is not limited by occlusion or calcification" 08/01/1994 - "Also, the initial improvement in minimal lumen diameter and final immediate postprocedural residual diameter stenosis were better with atherectomy" 11/01/1990 - "Atherectomy is superior to balloon dilation in the treatment of solitary eccentric stenoses of the superficial femoral artery and of the popliteal artery."

2.	Unstable Angina 11/15/1996 - "This study was undertaken to assess if the introduction of new angioplasty devices (autoperfusion balloon catheters, stent and atherectomy) could ameliorate early and late results of prompt percutaneous transluminal coronary angioplasty (PTCA) in patients with refractory unstable angina" 09/11/2007 - "ER chaperones also showed higher expression in atherectomy specimens from patients with unstable angina pectoris than in specimens from those with stable angina" 09/01/2006 - "Criteria for elective IABP support were (1) lesion located in the distal segment of the left main (bifurcation lesion), (2) left ventricular ejection fraction <40%, (3) atherectomy, (4) unstable angina, and (5) critical disease of the right coronary artery" 07/08/2003 - "Subacute closure lesions were compared with a control group (selected to be 3 times the abrupt closer group) matched by procedure date (within 6 months), age, gender, stable or unstable angina, lesion location, and additional treatment (balloon angioplasty or atherectomy)" 05/01/2003 - "RESULTS: The mean (+/- SD) percentage of macrophages in atherectomy specimens from patients with unstable angina was greater than in specimens from patients with stable angina (21% +/- 14% vs. 13% +/- 10%, P = 0.01); similar results were seen when complex coronary lesions were compared with simple lesions (23% +/- 13% vs. 9% +/- 8%, P <0.001)" Order ALL the reference details at left...
3.

Myocardial Infarction 05/01/1995 - "Directional atherectomy led to an initially higher gain in minimal lumen diameter for ostial lesions (1.13 vs. 0.56 mm, respectively, p < 0.001) but a higher rate of adjudicated non-Q wave myocardial infarction (24% vs. 13%, respectively, p < 0.001) than balloon angioplasty and no improvement in restenosis rates (48% vs. 46%, respectively)" 10/01/1996 - "CONCLUSIONS: The EPIC trial confirmed the increased risk of non-Q wave myocardial infarction with directional atherectomy use compared with PTCA" 10/01/1996 - "BACKGROUND: Randomized trials comparing directional atherectomy with percutaneous transluminal coronary angioplasty (PTCA) have demonstrated modest benefits favoring atherectomy but at a cost of increased acute ischemic complications, notably non-Q wave myocardial infarction" 10/01/1996 - "Increased risk of non-Q wave myocardial infarction after directional atherectomy is platelet dependent: evidence from the EPIC trial" 06/01/1995 - "Characteristics and consequences of myocardial infarction after percutaneous coronary intervention: insights from the Coronary Angioplasty Versus Excisional Atherectomy Trial (CAVEAT)."
