摘要(Abstract)：

冠状动脉钙化病变经常贯穿于各种复杂病变，增加了冠状动脉介入治疗的难度，尤其是重度钙化病变通常不能被充分扩张，导致手术成功率降低，急性或亚急性支架内血栓形成及再狭窄率增高，严重影响患者预后。随着经皮冠状动脉腔内冲击波球囊导管成形术（IVL）在钙化病变中使用越来越多。目前临床证据主要集中在稳定型心绞痛和不稳定型心绞痛的患者，但在急性ST段抬高型心肌梗死（STEMI）中应用有限，国外仅有个别病例报道，而且《冠状动脉钙化病变诊治中国专家共识（2021版）》将血栓病变列为IVL禁忌证。本病例是IVL在STEMI合并血栓病变中的紧急应用。本例STEMI合并血栓病变在支架置入后严重膨胀不良，探索住院期间强化抗凝治疗后，择期采用IVL处理，取得较好疗效。
