In a late-breaking clinical trial session at VIVA22, Dr. Ehrin Armstrong presented the final 1,373 patient cohort data from the DISRUPT PAD III Observational Study (OS). DISRUPT PAD III OS represents the largest prospective ‘real-world’ evidence for the treatment of complex, heavily calcified peripheral artery disease. Building on the interim results presented at VIVA21, this larger patient data set reinforces the predictability of IVL and its ability to consistently modify calcium across vessel beds, challenging lesions, and complex patients (CLTI, dialysis, and female patients). These real-world outcomes mirror the previously reported DISRUPT PAD III Randomized-Controlled Trial showing that IVL safely and effectively modifies challenging calcium in complex patients. 

Check-out the presentation below and hear from Dr. Armstrong on the importance of the largest prospective ‘real-world’ data set in the treatment of heavily calcified PAD. 

In this webcast recorded at TCT 2022, Prof. Javier Escaned and Dr. Nieves Gonzalo from Clinico San Carlos Madrid, and Dr. Angela McInerney, from University Hospital Galway, share their experience with IVL and the results from their most recent studies.

Dr. Mclnerney discusses about the results of a multicentre prospective study conducted within 14 centres in Spain to evaluate IVL in real-world scenarios and to compare MSA post IVL in different calcium morphologies. The results show that IVL is very effective across all calcium morphologies as there was no significant difference in MSE across concentric, eccentric and nodular calcium.

Dr. Gonzalo speaks about a multicentre study conducted in 2 large centres in Spain, with the objective of evaluating the long-term angiographic results following IVL, assess changes in MSA and study patterns of vessel healing after IVL treatment and understand the durability of the therapy. Results from this study showed that MLD and MSA are both maintained at follow up, with a low percentage of restenosis, no signs of recoil, and complete healing of the IVL-induced cracks.

In this short video, Dr. Sundeep Kalra, Royal Free Hospital of London, UK, shares his experience with Shockwave IVL, highlighting his evolution in the use of the technology since he started in 2016. At that time, his main indication for use of IVL was severely calcified coronary arteries with > 270° arc of calcium on intravascular imaging. Nowadays, Dr. Kalra uses Shockwave IVL to treat the whole lesion throughout all calcium morphologies, to ensure good plaque modification and achieve greater stent expansion.

Here, Dr. Kalra presents one of his recent clinical cases with Shockwave IVL: a 77-year-old woman with worsening stable angina and severe calcified left anterior descending artery (LAD). The patient was treated with a 3.0 mm Shockwave C2, using 50 shocks to fracture nodular calcium and 30 shocks for the eccentric plaque, followed by stent placement.

Did you get a chance to watch the educational symposium on nodular calcium at TCT 2022? If you missed it, we’ve got you covered!

In this session, leading complex PCI operators and calcium experts share their challenging nodular calcium cases while reviewing the pros and cons of existing calcium modification devices, including current clinical evidence and knowledge gaps. Listen to their debate on different treatment strategies for nodular calcium via atherectomy, IVL, and atherectomy + IVL.

A very informative session with a great discussion – Enjoy the debate!

Dr. Jaikirshan J. Khatri, MD, FACC, FSCAI Director of Complex Coronary Intervention Heart, Vascular & Thoracic Institute, at Cleveland Clinic; Cleveland, Ohio shares his calcium modification approach with Shockwave coronary IVL, including his best practices for pulse management as well as how calcium is affected by the fractures caused by coronary IVL.

Coronary Important Safety Information:

In the United States: Rx only.

Indications for Use—The Shockwave Intravascular Lithotripsy (IVL) System with the Shockwave C2 Coronary IVL Catheter is indicated for lithotripsy-enabled, low-pressure balloon dilatation of severely calcified, stenotic de novo coronary arteries prior to stenting.

Contraindications—The Shockwave C2 Coronary IVL System is contraindicated for the following: This device is not intended for stent delivery. This device is not intended for use in carotid or cerebrovascular arteries.

Warnings— Use the IVL Generator in accordance with recommended settings as stated in the Operator’s Manual. The risk of a dissection or perforation is increased in severely calcified lesions undergoing percutaneous treatment, including IVL. Appropriate provisional interventions should be readily available. Balloon loss of pressure was associated with a numerical increase in dissection which was not statistically significant and was not associated with MACE.  Analysis indicates calcium length is a predictor of dissection and balloon loss of pressure.  IVL generates mechanical pulses which may cause atrial or ventricular capture in bradycardic patients. In patients with implantable pacemakers and defibrillators, the asynchronous capture may interact with the sensing capabilities. Monitoring of the electrocardiographic rhythm and continuous arterial pressure during IVL treatment is required.  In the event of clinically significant hemodynamic effects, temporarily cease delivery of IVL therapy.

Precautions— Only to be used by physicians trained in angiography and intravascular coronary procedures. Use only the recommended balloon inflation medium. Hydrophilic coating to be wet only with normal saline or water and care must be taken with sharp objects to avoid damage to the hydrophilic coating. Appropriate anticoagulant therapy should be administered by the physician. Precaution should be taken when treating patients with previous stenting within 5mm of target lesion.

Potential adverse effects consistent with standard based cardiac interventions include– Abrupt vessel closure – Allergic reaction to contrast medium, anticoagulant and/or antithrombotic therapy-Aneurysm-Arrhythmia-Arteriovenous fistula-Bleeding complications-Cardiac tamponade or pericardial effusion-Cardiopulmonary arrest-Cerebrovascular accident (CVA)-Coronary artery/vessel occlusion, perforation, rupture or dissection-Coronary artery spasm-Death-Emboli (air, tissue, thrombus or atherosclerotic emboli)-Emergency or non-emergency coronary artery bypass surgery-Emergency or non-emergency percutaneous coronary intervention-Entry site complications-Fracture of the guide wire or failure/malfunction of any component of the device that may or may not lead to device embolism, dissection, serious injury or surgical intervention-Hematoma at the vascular access site(s)-Hemorrhage-Hypertension/Hypotension-Infection/sepsis/fever-Myocardial Infarction-Myocardial Ischemia or unstable angina-Pain-Peripheral Ischemia-Pseudoaneurysm-Renal failure/insufficiency-Restenosis of the treated coronary artery leading to revascularization-Shock/pulmonary edema-Slow flow, no reflow, or abrupt closure of coronary artery-Stroke-Thrombus-Vessel closure, abrupt-Vessel injury requiring surgical repair-Vessel dissection, perforation, rupture, or spasm. Risks identified as related to the device and its use: Allergic/immunologic reaction to the catheter material(s) or coating-Device malfunction, failure, or balloon loss of pressure leading to device embolism, dissection, serious injury or surgical intervention-Atrial or ventricular extrasystole-Atrial or ventricular capture.

Despite often being more challenging to treat, female PCI patients are under-represented in published data, with no dedicated prospective studies performed on this population. To address this unmet need, Shockwave is launching EMPOWER CAD, the first prospective, female-only study of coronary interventions.

EMPOWER CAD brings together some of the leading female interventionalists in the community to determine whether the positive results from earlier coronary IVL studies can be replicated in an expanded “real-world” population of female patients with severely calcified coronary lesions.

Please see our press release below and hear our female co-principal investigators, Margaret McEntegart, MD and Alexandra Lansky, MD talk about disparities in PCI outcomes and the rationale behind EMPOWER CAD.

At AMP 2022, Dr. Peter Soukas presented the largest set of real-world data on Shockwave IVL in CLTI patients. These data include results from patient groups historically not included in other PAD studies, such as Rutherford 6 and dialysis patients, and patients with single or absent vessel run-off. These data show the significant reduction of stenosis post-IVL in these patients, the minimal complications and the consistent results across multiple vessel beds. In this presentation Dr. Soukas shares why these data are important for physicians who treat CLTI, and how his calcium modification algorithm has changed over time with IVL.

Dr. Suzanne J. Baron of Lahey Hospital and Medical Center, Burlington, Massachusetts talks about gender disparities of PCI outcomes in calcified lesions, citing the recent SCAI Expert Consensus Statement, which brings to light the under-representation of women in cardiovascular clinical trials. Dr. Baron also talks about the impact of Shockwave IVL to improve outcomes in women with calcified disease based on the recently published sex specific analysis of DISRUPT CAD Pooled data at SCAI 2022.
