\"SizeThough sizing 1:1 to the healthy RVD may be a customary approach seen in other devices like traditional balloon angioplasty, peripheral IVL is an exception to the rule. It\u2019s recommended to oversize peripheral IVL by 10% (a ratio of 1.1:1) to the healthy RVD because it achieves better and sustained wall apposition, which leads to more efficient energy transfer from the IVL device.1, 2, 3<\/sup><\/p>\n

Under-sizing often happens with peripheral IVL (and other endovascular devices) due to concerns over safety and the limitations of angiography, which can result in undertreatment. However, it\u2019s important to remember that IVL operates at ultra-low pressures and is different from traditional angioplasty in that it relies on sonic pressure waves to do the calcium cracking, not mechanical force from the balloon itself. In addition, the DISRUPT PAD clinical program shows very low complication rates with IVL across peripheral vessel beds, even when the device is oversized by 10% or greater.<\/p>\n
