The challenges of BTK are made worse by stubborn calcium, with therapies challenged by dissections,1 poor vessel expansion2 and acute recoil.3 With Shockwave IVL, you can safely modify both superficial and deep calcium at ultra-low pressures that won’t impact soft tissue4 — plus our mechanism of action (MOA) is specifically built to treat BTK arteries.

1: Intravascular Lithotripsy for the Treatment of Patients with Critical Limb Ischemia, Peter A. Soukas, MD. Presented at The Amputation Prevention (AMP) Symposium. Chicago, IL. USA, August 2022.
An 86-year-old female Rutherford 5 CLTI patient with extensive BTK disease had a medical history that included coronary artery disease (CAD), diabetes mellitus-2, hypertension, hyperlipidemia, end stage renal disease on hemodialysis (HD), former smoker and diastolic congestive heart failure. With a high take-off of the anterior tibial, IVUS showed a reference vessel diameter of 3.5 mm with extensive calcification. A Shockwave M5+ 4.0 mm catheter was used to treat the ATA and TPT for an excellent angiographic result. The follow-up duplex scan showed patency in both the AT and TPT with wound healing at about 4–5 weeks. Case courtesy of Dr. JD Corl.
