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.

DISRUPT CAD Pooled Gender Analysis is now in published in JSCAI – the new journal of the Society for Cardiovascular Angiography & Interventions. Read the JSCAI publication here: https://www.jscai.org/article/S2772-9303(21)00011-9/fulltext

“Given the strong safety profile of IVL and the known higher risks of women undergoing PCI, coronary IVL is an attractive option for optimizing outcomes in female patients,” said Alexandra Lansky, MD, FACC, FAHA, FSCAI, FESC, Professor of Medicine (Cardiology), Director of Yale Cardiovascular Clinical Research Program Yale University School of Medicine, New Haven, CT, and Editor in Chief of JSCAI. “While this is the first analysis of its kind for coronary IVL, it is highly suggestive that the technology could potentially serve as first-line therapy for women with calcified lesions, particularly if these findings can be confirmed in a larger patient cohort.”

In addition to the publication of the gender analysis in the first issue, it also included a new Expert Consensus Statement from SCAI on Sex-Specific Considerations in Myocardial Revascularization, which includes reference to the new Coronary IVL gender data and the role that IVL can play in women as a potential first-line therapy for plaque modification of calcified lesions in women. Read the SCAI Consensus Statement here: https://www.jscai.org/article/S2772-9303(21)00016-8/fulltext

About JSCAI: JSCAI is an online only, peer-reviewed, international, Gold Open Access journal covering the broad field of cardiovascular diseases. JSCAI aims to be a highly credible and well-balanced reference highlighting practical techniques and pathways of care to deliver high impact scientific contributions from clinicians and colleagues in interventional cardiology.

Transfemoral access represents the gold standard for TAVI, with TF access showing a significant reduction in complications and mortality in comparison to alternative access strategies, which add additional complexity and risk to the procedure. Despite the wide acceptance that the transfemoral route provides the safest access for patients, the approach can be hindered by calcified iliac arteries inhibiting delivery of large bore devices by restricting the luminal diameter and reducing vessel compliance. If calcium is not treated adequately prior to TAVI delivery, this can lead to complications such as flow limiting dissection, vessel rupture and unsuccessful delivery of the implant.

Watch as Dr. Ole De Backer of Rigshospitalet, Copenhagen walks you through how intravascular lithotripsy (IVL) has expanded the boundaries of transfemoral TAVI. During this tutorial series Dr. De Backer will provide a detailed explanation of why, how and when IVL can be utilised to improve procedural safety and outcomes for patients undergoing transfemoral TAVI where calcium proves to be an inhibiting factor.
