Echocardiography remains the cornerstone for diagnosing primary mitral regurgitation, while cardiovascular magnetic resonance is gaining progressive relevance as an alternative method of choice.
Echocardiography is the primary imaging modality for evaluating primary mitral regurgitation, with cardiovascular magnetic resonance emerging as a valuable alternative.
Supports echocardiography-first approach for primary MR; leaves open CMR integration pending prospective outcome trials.
Primary mitral regurgitation (MR) is the first cause of valvular regurgitation in Western countries. Echocardiography is the cornerstone for diagnosing MR and more specifically for establishing its aetiology and mechanism, for quantifying its severity, progression, and repercussion and for assessing the likelihood of successful of valve repair. Two-dimensional/three-dimensional transthoracic and transoesophageal echocardiography are the most widely used methods. Interest is growing for exercise echocardiography particularly in patients in whom symptoms do not correlate well with MR severity and for risk stratification. The experience of multi-slice computed tomography in primary MR is still limited. Conversely, cardiovascular magnetic resonance has gained progressive relevance and represents the alternative method of choice.

Heyning et al. (2011) conducted a review in Primary mitral regurgitation. Multi-imaging modalities (Echocardiography, CT, CMR) was evaluated. Echocardiography remains the cornerstone for diagnosing primary mitral regurgitation, while cardiovascular magnetic resonance is gaining progressive relevance as an alternative method of choice.
