BACKGROUND
Left ventricular pseudoaneurysm is a rare condition whose prognosis and treatment are not well described.
CASE SUMMARY
We report a case of left ventricular pseudoaneurysm of iatrogenic origin, occurring after transcatheter mitral implantation. The patient underwent successful percutaneous closure with an occluder.
DISCUSSION
The formation of a pseudoaneurysm is potentially fatal. The main causes are ischemic, postsurgical, and infectious and after percutaneous valve replacement. Diagnosis is based on nonspecific symptoms and multimodal imaging. Treatment may be medical, surgical, or percutaneous, depending on the clinic, imaging, and the decision of the heart team.
TAKE-HOME MESSAGES: Left ventricular pseudoaneurysm after percutaneous valve implantation is a rare complication. Physicians could consider pseudoaneurysm percutaneous exclusion with an occluder.
背景
左心室假性动脉瘤是一种罕见病症，其预后和治疗方法尚无详尽描述。
病例摘要
我们报告一例经导管二尖瓣植入术后发生的医源性左心室假性动脉瘤病例。该患者通过封堵器成功进行了经皮闭合术。
讨论
假性动脉瘤的形成有潜在致命风险。主要病因包括缺血性、术后、感染性以及经皮瓣膜置换术后。诊断基于非特异性症状和多模态成像。治疗方式可根据临床情况、成像结果以及心脏团队的决策选择药物治疗、手术治疗或经皮治疗。
要点
经皮瓣膜植入术后的左心室假性动脉瘤是一种罕见并发症。医生可考虑使用封堵器进行假性动脉瘤经皮封堵术。
