Table 20 Recommendations for CMR in the guidelines on diagnosis and management of hypertrophic cardiomyopathy

Recommendations for cardiovascular magnetic resonance evaluation in hypertrophic cardiomyopathy (HCM)

It is recommended that CMR studies be performed and interpreted by teams experienced in cardiac imaging and in the evaluation of heart muscle disease

I

C

In the absence of contraindications, CMR with LGE is recommended in patients with suspected HCM who have inadequate echocardiographic windows, in order to confirm the diagnosis

I

B

In the absence of contraindications, CMR with LGE should be considered in patients fulfilling diagnostic criteria for HCM, to assess cardiac anatomy, ventricular function, and the presence and extent of myocardial fibrosis

IIa

B

CMR with LGE imaging should be considered in patients with suspected apical hypertrophy or aneurysm

IIa

C

CMR with LGE imaging should be considered in patients with suspected cardiac amyloidosis

IIa

C

CMR with LGE may be considered before septal alcohol ablation or myectomy, to assess the extent and distribution of hypertrophy and myocardial fibrosis

Recommendations on routine follow-up

CMR may be considered every 5 years in clinically stable patients, or every 2–3 years in patients with progressive disease
