In-stent Restenosis, Drug-coated balloon
Brief summary
The purpose of this observational study was to evaluate the long-term efficacy and safety of a paclitaxel-coated balloon catheter in coronary in-stent restenosis (ISR) patients. The primary endpoint was target lesion failure (TLF, a composite of cardiac death, target-vessel MI, or target lesion revascularization) at 12 months.
Detailed description
260 subjects treated with a paclitaxel-coated balloon (Genoss® DCB) in patients with coronary in-stent restenosis (ISR) will be recruited and followed up to 12 months. All enrolled patients treated with Genoss DCB in patients with coronary in-stent restenosis (ISR) will be included in the analysis unless there is a valid reason or rationale for it, and the final statistical analysis will follow the intention-to-treat (ITT) principle as assigned. Standard descriptive statistics will be used for patient baseline characteristics, lesions, procedures, and clinical event outcomes. Categorical variables will be presented as percentages and numbers and compared using chi-square or Fisher's exact test. Continuous variables will appear as mean, standard deviation or median, and interquartile range, and will be compared with Student's T-test or Wilcoxon rank sum test, and the normal value of the standard variable distribution will be predicted through histogram, skewness, kurtosis, and Kolmogorov Smirnov one sample test.
