Valvular regurgitation is common in developed countries with an increasing prevalence due to the aging of the population and more accurate diagnostic imaging methods. Echocardiography is the gold standard method for the assessment of the severity of valvular heart regurgitation. Nonetheless, cardiovascular magnetic resonance (CMR) has emerged as an additional tool for assessing mainly the severity of aortic and mitral valve regurgitation in the setting of indeterminate findings by echocardiography. Moreover, CMR is a valuable imaging modality to assess ventricular volume and flow, which are useful in the calculation of regurgitant volume and regurgitant fraction of mitral valve regurgitation, aortic valve regurgitation, tricuspid valve regurgitation, and pulmonary valve regurgitation. Notwithstanding this, reference values and optimal thresholds to determine the severity and prognosis of valvular heart regurgitation have been studied lesser by CMR than by echocardiography. Hence, further larger studies are warranted to validate the potential prognostic relevance of the severity of valvular heart regurgitation determined by CMR. The present review describes, analyzes, and discusses the use of CMR to determine the severity of valvular heart regurgitation in clinical practice.
在发达国家，由于人口老龄化和更精确的诊断成像方法，瓣膜反流很常见且患病率不断上升。超声心动图是评估心脏瓣膜反流严重程度的金标准方法。尽管如此，心血管磁共振成像（CMR）已成为一种辅助工具，主要用于在超声心动图检查结果不明确的情况下评估主动脉瓣和二尖瓣反流的严重程度。此外，CMR是评估心室容积和血流的一种有价值的成像方式，这对于计算二尖瓣反流、主动脉瓣反流、三尖瓣反流和肺动脉瓣反流的反流容积和反流分数很有用。尽管如此，与超声心动图相比，CMR对确定心脏瓣膜反流严重程度和预后的参考值及最佳阈值的研究较少。因此，有必要进行更大规模的进一步研究，以验证CMR所确定的心脏瓣膜反流严重程度的潜在预后相关性。本综述描述、分析并讨论了CMR在临床实践中用于确定心脏瓣膜反流严重程度的应用。
