Abstract

Purpose of review: Dysfunction and thrombosis of mechanical heart valves, although uncommon, represents a challenge that requires multidisciplinary expertise for diagnosis and management. The aim of this review is to summarize strengths and weaknesses of diagnostic methods and therapeutic strategies for this uncommon but potentially life-threatening pathology.

Recent findings: Expeditious diagnosis of mechanical valve thrombosis and exclusion of other diagnostic considerations, often with incorporation of multimodality imaging, can inform the best treatment strategy. Presentation of mechanical valve thrombosis can be asymptomatic or can include heart failure, life-threatening embolic events, or cardiogenic shock. Echocardiography, fluoroscopy and computed tomography are important in the evaluation of mechanical valve dysfunction. Therapeutic strategies for thrombosis include anticoagulation, systemic thrombolysis, and surgery. Choice of treatment depends on multiple factors including thrombus size, degree of valve dysfunction, clinical presentation, and available surgical expertise.

机械心脏瓣膜功能障碍和血栓形成的评估与管理。

综述的目的：机械心脏瓣膜的功能障碍和血栓形成虽然并不常见，但却是一项挑战，需要多学科专业知识进行诊断和管理。本综述旨在总结这种不常见但可能危及生命的病症的诊断方法和治疗策略的优缺点：最新研究结果：快速诊断机械瓣膜血栓并排除其他诊断因素（通常结合多模式成像）可为最佳治疗策略提供依据。机械瓣膜血栓的表现可以是无症状，也可以包括心力衰竭、危及生命的栓塞事件或心源性休克。超声心动图、透视和计算机断层扫描对于评估机械瓣膜功能障碍非常重要。血栓形成的治疗策略包括抗凝、全身溶栓和手术。治疗方法的选择取决于多种因素，包括血栓大小、瓣膜功能障碍程度、临床表现和可用的外科专业知识。

期刊介绍： The aim of this journal is to provide timely perspectives from experts on current advances in cardiovascular medicine. We also seek to provide reviews that highlight the most important recently published papers selected from the wealth of available cardiovascular literature. We accomplish this aim by appointing key authorities in major subject areas across the discipline. Section editors select topics to be reviewed by leading experts who emphasize recent developments and highlight important papers published over the past year. An Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. We also provide commentaries from well-known figures in the field.
