To what extent is prolapse of the mitral valve associated with mitral regurgitation and the risk of infective endocarditis, rupture of the chordae tendineae, and sudden death? Earlier studies used differing definitions and criteria, and reported prevalence of this deformity varied widely, especially between referral and general population studies. Advances in echocardiography have clarified the diagnosis, allowing classification of prolapse into subtypes associated with different degrees of risk and prognoses.
二尖瓣脱垂与二尖瓣反流、感染性心内膜炎风险、腱索断裂及猝死的关联程度如何？早期研究使用了不同的定义和标准，且报道的这种畸形的患病率差异很大，尤其是在转诊研究和普通人群研究之间。超声心动图技术的进步已使诊断更加明确，能够将脱垂分为与不同风险程度和预后相关的亚型。
