Coronary Laser in Undilatable or Uncrossable Lesions

NCT07206082 · Status: ACTIVE_NOT_RECRUITING · Type: OBSERVATIONAL · Enrollment: 230

Last updated 2025-10-03

No results posted yet for this study

Summary

This will be an investigator-initiated, multicentre, single-arm, open-label, prospective observational study. Patients with indication for PCI and undilatable (non-compliant balloon dilatation \<80% at burst pressure) or uncrossable (not crossable with a "small-profile balloon" with adequate support, according to operator´s discretion) coronary lesions treated with ELCA will be included. Intravascular imaging will be highly recommendable and analysed in a central core-laboratory. Device success, angiographical success, procedural success, clinical success and related complications will be evaluated. Patients will be followed for 1 year after the procedure and clinical events will be recorded.

DEVICE

Laser atherectomy

ELCA procedure will be performed using the Spectranetics CVX300 (Spectranetics, Colorado Spring, CO, USA) and the latest generation Philips Laser System Excimer (Philips, San Diego, CA, USA) System, which is based on pulsed xenon-chlorine laser catheters capable of delivering excimer energy (wavelength 308 nm, pulse length 185 ns) from 30 to 80 mJ/mm2 (fluencies) at pulse repetition rates from 25 to 80 Hz. The ELCA technique will be performed according to current recommendations (18). The laser probe size will be at the operator´s discretion among the available options (rapid exchange concentric 0.9 mm, 1.4 mm, 1.7mm or 2.0mm). The selection of fluence, and repetition rate will be left to the operator. A saline infusion technique will be recommended, although application of laser with blood or contrast will be recommended in resistant lesions. In the event of unsuccessful initial therapy, additional plaque modification techniques may be employed at the discretion of the operator and wi
