Fig. 2From: Fracking compared to conventional balloon angioplasty alone for calcified common femoral artery lesions using intravascular ultrasound analysis: 12-month resultsComparison of primary patency and freedom from TLR between fracking and conventional balloon angioplasty. A Primary patency and (B) freedom from target lesion revascularization rate for up to 1 year and 1 month after the fracking and balloon angioplasty procedures are shown. The figures show that both primary patency and freedom from TLR rates were significantly higher in the fracking group than in the balloon groupBack to article page
