Evaluation by CMR

Consensus statement on CMR Symbol Ref
CMR should be performed in all AMVP patients who survived a cardiac arrest or experienced sustained VA, beforea implanting an ICD for secondary prevention. graphic file with name euac125il1.jpg 155,157
CMR should be performed in all patients when echocardiography does not provide accurate assessment of LV and RV function and/or evaluation of structural changes. graphic file with name euac125il1.jpg Expert consensus
CMR should be performed in all MVP patients with a history of unexplained syncope and/or NSVT. graphic file with name euac125il1.jpg Expert consensus
CMR should include assessment of LV size and function, assessment of MR severity, leaflet length/thickness measurement, MAD characterization and curling, and LGE assessment. graphic file with name euac125il1.jpg Expert consensus
CMR may be useful in patients with AMVP and at least 1 phenotypic risk featureb. graphic file with name euac125il2.jpg
a

CMR should not unduly delay the implantation of a defibrillator.

b

Phenotypic risk features—palpitations, T-wave inversion in the inferior leads, repetitive documented polymorphic PVCs, MAD phenotype, redundant MV leaflets, enlarged left atrium or ejection fraction ≤ 50%.

AMVP, arrhythmic mitral valve prolapse; CMR, cardiac magnetic resonance; ICD, implantable cardioverter defibrillator; LGE, late gadolinium enhancement; LV, left ventricular; MAD, mitral annular disjunction; MR, mitral regurgitation; RV, right ventricle; VA, ventricular arrhythmia.
