• Lead Sponsor: Hospital Universitario La Fe

Brief Summary

Coronary artery disease (CAD) is one of the most common causes of mortality worldwide. Despite drug eluting stents (DES) are the most common treatment strategy, drug-coated balloons (DCB) represent an appealing alternative to DES as they eliminate the risk of stent thrombosis and do not leave any type of metallic structure in the vessel wall. However, the evidence of the vessel wall healing processes, plaque remodeling, plaque composition and impact on coronary microcirculation after PCI with DCB have not yet been characterized.

The purpose of this study is to assess the changes in percentage atheroma volume evaluated by intravascular ultrasound (IVUS) in patients undergoing DCB-PCI.

Detailed Description

The study will be an investigator-initiated, single-arm, open-label, pilot study in patients undergoing PCI with DCB for the novo lesion.

Because of the exploratory nature of this study, no formal sample size calculation is required. On the basis of previous pilot studies with similar designs, a sample of 30 lesions is planned to be evaluated.

After being informed about the study and the potential risks, all patients meeting all the inclusion criteria and none of exclusion criteria will give written informed consent. Patients will go DCB-PCI. IVUS will be evaluated prior to PCI-DCB, immediately after and at 3-month follow-up. Angiography-derived coronary physiology will be assessed after the procedure using Angio Plus software (Pulse Medical Imaging Technology, Shanghai, China). The angiography images will be used to obtain the IMRangio values, prior, post to DCB-PCI and 3 month follow-up.
