About this study
Official title: Intravascular Lithotripsy and Rotational Atherectomy in Treatment of Severely Calcified Coronary Lesions
This study to compare periprocedural safety, angiographic success as well as short and long term outcomes of intravascular lithotripsy and rotational atherectomy as a method of severely calcified coronary lesion preparation before DES implantation.
Read the detailed description
Coronary artery calcification (CAC) occurs in over 90% of men and 67% of women older than 70 years old .
Severe coronary calcification may be present in about 20% of patients undergoing percutaneous coronary intervention (PCI) .
Coronary calcification may impair stent delivery and expansion and damage the polymer/drug coating, resulting in impaired drug delivery and predispose to restenosis and stent thrombosis.
Intravascular imaging as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are good tools to assess calcium burden, distribution and thickness. Among the two imaging techniques, OCT was found to be more accurate than IVUS in defining calcium burden, calcium area , thickness and calcium length.
Rotational atherectomy (RA) as a method of severely calcified lesions modification before Drug-Eluting-Stent (DES) implantation has shown good outcomes in recent studies. However, its efficacy is reduced in presence of deep calcification.
Recently, intravascular lithotripsy (IVL) has been introduced as a novel modality for severely calcified coronary lesion preparation with good preliminary outcomes .
Currently the two techniques are regularly being used in combination in order to achieve optimal results . Whether IVL is a method equally good (or superior) to rotablation in cases where anatomy does not exclude the use of either technique (for example balloon-crossable, heavily calcified lesions) has not yet been discussed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Rotational atherectomyDevice
Device used for severely calcified coronary lesion preparation before stent implantation.
Intravascular lithotripsyDevice
Device used for severely calcified coronary lesion preparation before stent implantation.
| Study group | Role | What they receive |
|---|---|---|
| Patients who underwent Rotational atherectomy (RA) | The device contains rapidly rotating burr that is coated with microscopic diamond chips, which debulks the calcified plaque by grinding the calcified atheroma into small particles facilitating stent passage and expansion. Both transfemoral or transradial approach can be used. Regular PCI guidewire can be used to cross the often complex anatomy then switching to a rotablation dedicated guidewire over a microcatheter. Burr sizes vary from 1.25mm up to 1.75mm (in certain cases bigger calibers may also be used) aiming to achieve plaque modification . Receives: Device: Rotational atherectomy | |
| Patients who underwent Intravascular lithotripsy (IVL) | The Coronary IVL System consists of an IVL Balloon Catheter with 2 integrated emitters, a Lithotripsy Generator, and a Connector Cable. These emitters create sonic pressure waves that selectively fracture calcium and alter vessel compliance facilitating stent passage and expansion. It is available in 2.5- to 4.0-mm diameters and 12 mm in length, with an inflation pressure of 4 atm used for delivering the treatment. Every catheter can emit a maximum of 80 pulses at a rate of one pulse per second. The IVL balloon catheter is chosen based on the reference lumen of the vessel and after pre-dilatation of the lesion (preferably with a non-compliant balloon) 10-30 pulses are given, usually with interval deflation to allow distal perfusion. If the lesion exceeds the 12 mm balloon length, the balloon can be repositioned and the IVL repeated . Receives: Device: Intravascular lithotripsy |

Questions about this trial
What is this clinical trial studying?
An observational study of Coronary Calcification, run by Assiut University at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Strategy success (time frame: Up to one day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04556682, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Aug 2022.
