Native valvular emergencies are nearly always regurgitant in nature, whereas acute prosthetic valve dysfunction can be either regurgitant or stenotic. Regardless of the etiology, the presentation of acute valvular pathology differs significantly from chronic disease in both clinical presentation and in its appearance on diagnostic modalities, and appropriate recognition is critical to the choice of the appropriate therapeutic modality. Intrinsic to the recognition of a valvular emergency is a knowledge of those conditions for which a high index of suspicion must be maintained. This article addresses the etiologies, presentation, and diagnosis of these conditions and presents the relevant data that bears on which therapy may be most appropriate for which condition.
原发性瓣膜急症本质上几乎都是反流性的，而急性人工瓣膜功能障碍可能是反流性的，也可能是狭窄性的。无论病因如何，急性瓣膜病变在临床表现和诊断方式上的表现与慢性疾病均有显著差异，正确识别对于选择合适的治疗方式至关重要。识别瓣膜急症的关键在于了解那些必须保持高度怀疑指数的情况。本文阐述了这些情况的病因、表现和诊断，并提供了相关数据，这些数据有助于判断哪种治疗方式最适合哪种情况。
