Abstract:
Experience with intravascular lithotripsy (IVL) following stent deployment in saphenous vein graft (SVG) lesions is limited. We present 2 cases of percutaneous intervention in SVG in which acute stent underexpansion was successfully managed with IVL. In the first case, recalcitrant plaque required prestent deployment IVL, with intracoronary imaging showing persistent calcification. Additional poststent deployment IVL facilitated full expansion and successful stent delivery. In the second case, predilation with semicompliant balloons appeared angiographically effective, but stent deployment showed acute underexpansion. Postdilation with noncompliant balloons and ultimately IVL allowed full expansion and successful stent delivery. These are the first reported cases of IVL use immediately after stent deployment in SVG to treat underexpansion due to recalcitrant calcification.
