Prognostic value of quantitative flow ratio measured immediately after drug-coated balloon angioplasty for in-stent restenosis.
This study aimed to evaluate prognostic value of quantitative flow ratio (QFR) in drug-coated balloon (DCB) angioplasty for in-stent restenosis (ISR). ⋯ The QFR value after DCB angioplasty is a promising predictor of DES ISR.
