Coronary artery morphologic features after coronary rotational atherectomy: Insights into mechanisms of lumen enlargement and embolization

Acute and late clinical outcome after rotational atherectomy for complex coronary disease

“…Nineteen patients (11%) underwent planned staged rotational atherectomy procedures, and 14 patients (8%) had multiple lesions treated during their initial revascularization procedure. Most patients had complex coronary disease; 71% of treated lesions were AHA/ACC Type B 2 or C (Fig. 1).…”

“…A variety of different types of atherectomy catheters are now available to debulk coronary atheroma including directional, extraction, and high-speed rotational ablation devices. Percutaneous transluminal coronary rotational atherectomy (PTCRA) is unique in its ability to take advantage of the properties of differential cutting allowing ablation of fibrocalcific plaque while minimizing or avoiding disruption of soft elastic tissue [1][2][3][4][5]. This device is particularly useful in complex coronary disease in which lesion characteristics are often unfavorable for balloon angioplasty and for patients in whom suboptimal results or a high incidence of major complications are expected [1,[5][6][7][8].…”

Tissue Factor Expression in Coronary Circulation as a Prognostic Factor for Late Restenosis after Coronary Angioplasty

“…Application of coronary stents has reduced the incidence of acute coronary occlusion [21, 22]. Percutaneous transluminal rotational coronary atherectomy (PTRA) has also improved results in highly calcified lesions [23, 24]. Although these new interventions lowered the incidence of acute and subacute coronary occlusion, late restenosis of dilated coronary arteries is still an unsolved problem.…”

Role of Rotational Atherectomy in Percutaneous Coronary Interventions in Elderly

“…RA produces a smooth luminal surface and compared to balloon angioplasty and does not produces micro-dissections in the calcified plaques [9][10][11]. The final lumen diameter is larger that the size of the burr that is used.…”
