Intravascular ultrasound evaluation of the effect of rotational atherectomy in obstructive atherosclerotic coronary artery disease.

Abstract

Rotational atherectomy causes atheroablation with only moderate evidence of barotrauma in heavily calcified arteries, even after adjunct balloon angioplasty. The lumen is cylindrical, especially in areas of calcified plaque, and somewhat larger than the largest burr tip used.

Comparison of Long-Term Clinical Outcomes Between Sirolimus-Eluting Stents and Paclitaxel-Eluting Stents Following Rotational Atherectomy

“…RA can facilitate smooth stent delivery and stent expansion through lesion modification. [4][5][6] However, the clinical outcomes after implanting a baremetal stent (BMS) following RA have not been satisfactory. [7][8][9] Drug-eluting stents (DES) have dramatically reduced the rate of revascularization compared with BMS.…”

Incidence, Location, Magnitude, and Clinical Correlates of Saphenous Vein Graft Calcification

“…revious studies have reported the frequency and clinical significance of coronary artery calcification [1][2][3][4][5][6][7][8][9][10][11][12][13][14] ; however, no prior study has described the frequency, pattern, distribution, and clinical correlates of calcium in saphenous vein grafts (SVGs). Therefore, the purpose of this study was (1) to use intravascular ultrasound (IVUS) to determine the arc, length, location, orientation, and distribution of SVG calcification; (2) to compare these IVUS results with angiographic findings; and (3) to correlate SVG calcification with clinical characteristics.…”

Guidewire Bias in Rotational Atherectomy in the Angled Lesion. Evaluation Based on the Thickness of the Ablated Intima and Media.

“…[1][2][3][4] Studies using sequential IVUS imaging, before and after RA, have shown significant increases in minor and major lumen diameters, 2 a significant increase in lumen CSA, no significant change in EEM CSA, 1,2 and a significant decrease in plaque plus media CSA. 1,3 Dussaillant et al reported that the lumen volume significantly increased after RA as a result of a significant decrease in plaque plus media volume, with no change in total EEM volume.…”
