This clinical trial adopts a retrospective, multicenter design with data registered and collected via an Electronic Data Capture (EDC) system. A total of 252 eligible subjects will be enrolled in the trial, who are consecutively selected in accordance with the inclusion and exclusion criteria from 2022 to the end of 2023 in a retrospective manner. Data collection will be conducted at four time points for all enrolled subjects, including the screening period, 6 months (±30 days) after surgery, 12 months (±30 days) after surgery, and 24 months (±60 days) after surgery. Relevant data of retrospective subjects will be obtained by reviewing medical records.
Study Type
OBSERVATIONAL
Enrollment
252
subjects who have received coronary artery drug-coated balloon dilatation catheter treatment in the selected centers for a period of time since the product's marketing will be screened one by one in accordance with the inclusion and exclusion criteria. During the process, data collection will be conducted by direct medical history collection or reviewing medical records in the medical record system of each center.

the incidence of Target Lesion Failure (TLF).
The percentage of subjects who experience TLF from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects. TLF is defined as a composite endpoint of cardiac death, target vessel myocardial infarction (Q-wave or non-Q-wave MI), and clinically driven target lesion revascularization (CD-TLR).
Time frame: 24 months
Surgical success rate
The percentage of subjects with successful surgery among the total number of subjects. Surgical success is defined as visual residual stenosis diameter ≤30% at the target lesion after PCI, TIMI flow grade 3 (visual assessment), and no rescue stent implantation required.
Time frame: Immediately after the treatment
Incidence of stent thrombosis
The percentage of subjects with all stent thrombosis events meeting the ARC criteria (including definite and probable) from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects.
Time frame: 24 months
Incidence of device-related cardiovascular events (DoCE)
The percentage of subjects with device-related cardiovascular events from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects. The device-related clinical composite cardiovascular endpoint is defined as cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization.
Time frame: 24 months
Incidence of patient-related cardiovascular events (PoCE)
The percentage of subjects with patient-related cardiovascular events from the treatment of the target lesion with the investigational device to 24 months after surgery among the total number of subjects. The patient-related clinical composite cardiovascular endpoint is defined as all-cause death, all myocardial infarctions, and any repeat revascularization.
Time frame: 24 months
Device usage
The average number of investigational devices used per lesion and the adjuvant devices used.
Time frame: Immediately after the treatment
