Mitral regurgitation is a common valvular disorder found in the general population with varying degrees of severity. The symptoms of this disorder correspond to the severity of regurgitation as well as its associated complications such as arrhythmias. Suspicion of mitral regurgitation is based on physical exam findings with diagnosis generally requiring confirmatory findings on transthoracic echocardiogram. However, asymptomatic patients with mitral regurgitation and limited sensitivity of cardiac auscultation to detect a murmur confound the diagnosis. In this case, a patient presented with nonspecific symptoms of shortness of breath and abdominal pain in which a bedside point-of-care ultrasound (POCUS) in initial examination demonstrated severe mitral regurgitation and pulmonary edema. These findings expedited an intervention on the regurgitation, which highlights the importance of incorporation and early use of POCUS during physical examination.
二尖瓣反流是普通人群中常见的瓣膜疾病，严重程度各异。该疾病的症状与反流的严重程度及其相关并发症（如心律失常）相对应。二尖瓣反流的疑似诊断基于体格检查结果，而确诊通常需要经胸超声心动图的确认结果。然而，无症状的二尖瓣反流患者以及心脏听诊检测杂音的敏感性有限，这使得诊断变得复杂。在本病例中，一名患者出现了气短和腹痛等非特异性症状，初次检查时床边即时超声（POCUS）显示严重二尖瓣反流和肺水肿。这些发现加快了对反流的干预，突出了在体格检查中纳入并早期使用POCUS的重要性。
