This article is a review on the role of stress echocardiography in valvular heart diseases, describing what the validated indications are, how to perform the test and the utility of performing this examination. Most valve diseases are characteristically dynamic and this dynamic component is best appreciated by exercise Doppler echocardiography. Dobutamine stress echocardiography is also useful in patients with severe aortic stenosis and left ventricular dysfunction. The main advantage of stress echocardiography is to concomitantly allow the evaluation of symptoms, exercise capacity and the hemodynamic consequences of valve diseases, especially in patients with severe valve diseases who deny symptoms or present equivocal symptoms. It also provides important prognostic information and may help to optimize surgical timing in difficult cases. Whether these data should be integrated in the management of patients needs further validation.
本文是一篇关于负荷超声心动图在心脏瓣膜病中作用的综述,描述了其已被验证的适应证、检查方法以及该检查的用途。大多数瓣膜病具有典型的动态特征,而运动多普勒超声心动图最能体现这一动态成分。多巴酚丁胺负荷超声心动图对重度主动脉瓣狭窄和左心室功能不全患者也很有用。负荷超声心动图的主要优势在于能够同时评估症状、运动能力以及瓣膜病的血流动力学后果,特别是对于那些否认有症状或症状不明确的重度瓣膜病患者。它还能提供重要的预后信息,并有助于在疑难病例中优化手术时机。这些数据是否应纳入患者的管理仍需进一步验证。
