CALCIFIED SFA CTO WITH IVUS CASE STUDY

©2014 Spectranetics. All Rights Reserved. Approved for External Distribution D020237-02 032014

Is this a laser case? Moderately to severely calcified CTO

Patient History/ Details

• 67 y/o male • Progressive leg

claudication • Abnormal noninvasive

vascular study • Abnormal CT

angiogram • Smoker • Hyperlipidemia

• 6mm reference vessel • Vessel stenosis 95%

or greater • Lesion length roughly

10mm


Observe that there is calcium both inside AND outside the artery per IVUS. This differentiation is not evident with an angiogram. Endovascular therapies will only affect intraluminal calcium or plaque – YET many decisions to treat are based on angio only – and angio greatly overestimates the amount of intraluminal calcium.


Post 2.3 TE one pass at 45/45

Are we done lasing? Ready to PTA and/or stent?


Post 2.3 Turbo Elite – one pass at 45/45


Post 2.3 TE

31% luminal gain post TE with one pass (Luminal gain = the change in area divided by the original area)


Post Turbo-Tandem – 4 passes at 45/45

Note the luminal gain with a concentric and smooth lumen


260% luminal gain post TE and TT (4 passes at 45/45) alone


Turbo Tandem vs. SilverHawk 260% Luminal Gain post Laser

De Novo Lesion Pre SilverHawk¹

Post SilverHawk¹ 114% Luminal Gain

Average Area of Lumen pre SH: 7.0 mm2

Average Area of Lumen post SH: 15.0 mm2, 114% gain

Average Area of Lumen pre Laser: 4.5mm2 Average Area of Lumen post Laser: 16.2mm2, 260% gain

Post 6x120mm Stent


Final Result

471% luminal gain post laser atherectomy and stenting
