presence of adequate acoustic windows and operator experience.

CMR may provide additional diagnostic information when

echocardiographic imaging is suboptimal. However, the utility

of CMR for the evaluation of RHD may be limited by its

relative inability to be used in patients with certain types

of metallic implants, local artefacts from prosthetic valves,

lack of availability, expense of the tests and limited expertise

in RHD-endemic countries. Furthermore, data regarding

prognostic significance of CMR in RHD are lacking.
