Safety and Efficacy of GENOSS® DCB With a Shellac Plus Vitamin E Excipient in Patients With De Novo Lesion

This prospective, open-label, multicenter, observational study will enroll patients with de novo small coronary artery disease undergoing PCI with the GENOSS® DCB at 47 hospitals.

Because this is an observational study, the number of participants will not be calculated separately, but a total of 3,000 participants are planned to be recruited during the study enrollment period.

All patients will be followed up at 1, 2, and 3 years postprocedure to evaluate the safety and efficacy of the paclitaxel-coated PTCA balloon catheter.

Inclusion criteria

• Adults over the age of 19
• Patients with new lesions with coronary small vascular disease (vascular diameter <3.0 mm) underwent a GENOSS® DCB procedure through percutaneous coronary intervention
• Subjects who agreed to the clinical research plan and the clinical follow-up plan, voluntarily decided to participate in this clinical study, and agreed in writing to the consent of the study subjects

Exclusion criteria

• Subjects who plan to become pregnant during the period of this study as women of the gestational age
• Subjects whose remaining life expectancy is expected to be less than one year
• Subjects who visited the hospital due to psychogenic shock at the time of visiting the hospital and are predicted to have a low chance of survival based on medical judgment
• If it falls under any of the following items after prior dilation of the target lesion;

• Stent procedures are required due to vascular detachment that limits blood flow
• If the residual stenosis is >30%
• If the TIMI flow is <3
• Subjects participating in a randomized study of medical devices
• If the researcher determines that it is not appropriate for this clinical study or may increase the risk associated with participation in the study
