Rupture of the papillary muscle is a serious complication of acute myocardial infarction (AMI), usually leading to mitral valve dysfunction and severe regurgitation, which in turn causes acute heart failure, posing a significant threat to the patient's life.
This case report aims to explore the feasibility and effectiveness of the DragonFly™ system in patients with papillary muscle rupture following AMI. We describe a 71-year-old male patient who was admitted due to chest tightness and chest pain, and upon examination, severe mitral regurgitation and papillary muscle rupture were found. Although the patient had missed the opportunity for emergency reperfusion, due to significant symptoms and heart failure, the cardiac team decided to perform a transcatheter edge-to-edge repair (TEER) of the mitral valve. During the procedure, guided by ultrasound and imaging, two valve clips were successfully implanted, significantly improving the mitral regurgitation. Postoperative assessment showed a reduction in regurgitation from 4 + to 1+, and the patient was discharged smoothly.
Patients with AMI accompanied by papillary muscle rupture have poor condition.

乳头肌破裂是急性心肌梗死（AMI）的一种严重并发症，通常会导致二尖瓣功能障碍和严重反流，进而引起急性心力衰竭，对患者生命构成重大威胁。
本病例报告旨在探讨DragonFly™系统在急性心肌梗死后乳头肌破裂患者中的可行性和有效性。我们描述了一名71岁男性患者，因胸闷和胸痛入院，检查发现严重二尖瓣反流和乳头肌破裂。尽管患者错过了紧急再灌注的机会，但由于症状严重且出现心力衰竭，心脏团队决定对二尖瓣进行经导管缘对缘修复（TEER）。手术过程中，在超声和成像引导下，成功植入了两个瓣膜夹，显著改善了二尖瓣反流。术后评估显示反流从4+降至1+，患者顺利出院。
急性心肌梗死合并乳头肌破裂的患者病情较差。
不适用。
