Atherectomy Devices

This channel includes news and new technology innovations for atherectomy systems used in peripheral or coronary arteries to debulk lesions and vessel preparation prior to angioiplasty or stenting.

Angiography shows a stenotic lesion in the mid right coronary artery, undilatable by standard high-pressure balloon angioplasty (inset, arrowheads). (B) Optical coherence tomography (OCT) cross-sectional (top) and longitudinal (bottom) images acquired before IVL and coregistered to the OCT lens (arrow in A) demonstrate severe near-circumferential calcification in the area of the stenosis. (C) Angiography demonstrates improvement in the area of stenosis after IVL lithoplasty.

Figure 2: Angiography demonstrates a stenotic lesion in the mid right coronary artery, undilatable by standard high-pressure balloon angioplasty (inset, arrowheads). (B) Optical coherence tomography (OCT) cross-sectional (top) and longitudinal (bottom) images acquired before IVL and coregistered to the OCT lens (arrow in A) demonstrate severe near-circumferential calcification (double-headed arrow) in the area of the stenosis. (C) Angiography demonstrates improvement in the area of stenosis after IVL (inset; note the cavitation bubbles generated by IVL [black arrows]). (D) OCT cross-sectional (top) and longitudinal (bottom) images acquired post-IVL and coregistered to the OCT lens (white arrow in C) demonstrate multiple calcium fractures and large acute luminal gain. (E) Angiography demonstrates complete stent expansion with the semicompliant stent balloon (inset) without the need for high-pressure noncompliant balloon inflation. (F) OCT cross-sectional (top) and longitudinal (bottom) images acquired post-stenting and coregistered to the OCT lens (arrow in E) demonstrate further fracture displacement (arrow), with additional increase in the acute area gain (5.17 mm2), resulting in full stent expansion and minimal malapposition.
