Heavily calcified lesions may limit optimal stent deployment resulting in stent underexpansion, thus increasing the risk of restenosis and thrombosis. We describe the case of overlapping stents underexpansion treated with a shockwave intravasuclar lithoplasty system (Shockwave Medical Inc., Santa Clara, CA, USA). A 65-year-old man with angina, underwent coronary angiography and intravascular ultrasound showing restenosis, in a site of overlapping stents, due to calcified tissue. Shockwave lithoplasty balloon was able to break calcified tissue in a site of overlapping stents, allowing subsequent vessel dilation and repeat stent implantation with optimal final stent expansion. <> Heavily calcified lesions may limit optimal stent deployment resulting in stent underexpansion. Treating stent underexpansion or restenosis due to calcified tissue is a great challenge. Shockwave lithoplasty is effective in breaking calcified tissue also in a site of overlapping stents. The improved plaque compliance allows to repeat stent implantation with optimal final stent expansion.
严重钙化病变可能会限制支架的最佳展开，导致支架扩张不足，从而增加再狭窄和血栓形成的风险。我们描述了一例使用冲击波血管内碎石术系统（美国加利福尼亚州圣克拉拉市的冲击波医疗公司）治疗重叠支架扩张不足的病例。一名65岁的男性患者，患有心绞痛，接受冠状动脉造影和血管内超声检查，结果显示在重叠支架部位由于钙化组织导致再狭窄。冲击波碎石术球囊能够在重叠支架部位破碎钙化组织，从而实现后续血管扩张，并能再次植入支架，使支架最终实现最佳扩张。严重钙化病变可能会限制支架的最佳展开，导致支架扩张不足。治疗因钙化组织导致的支架扩张不足或再狭窄是一项巨大挑战。冲击波碎石术在重叠支架部位破碎钙化组织方面同样有效。斑块顺应性的改善使得能够再次植入支架，并使支架最终实现最佳扩张。
