First Human Use of Shockwave L6 Intravascular Lithotripsy Catheter in Severely Calcified Large Vessel Stenoses

BackgroundIntravascular lithotripsy (IVL) modifies superficial and deep vascular calcium by delivering pulsatile sonic pressure energy that fractures in situ with the consequent enhancement of transmural vessel compliance, limitation fibroelastic recoil, optimization stent implantation. To date, use IVL as an adjunct to facilitate implantation has been limited large target size eccentricity distribution.MethodsThe Shockwave L6 balloon delivery system includes 6 emitters mounted on shaft a 30.0-mm long diameters ranging from 8.0 12.0 mm. The nominal is 4 atm. We describe first human this novel covered severely calcified stenoses involving distal abdominal aorta bilateral iliac arteries.ResultsFull expansion was achieved at low pressures (3 atm), despite severity calcification, subsequent safe effective implantation.ConclusionsThe seems expand application treatment vessels, such arteries.
