Results
MRI in cardiac morphological evaluation in pre-clinical-HCM stage in particular ventricular wall thickness assessment revealed to be superior to the echocardiogram with narrower limit of agreement.
Echocardiography underestimated the wall thickness at anteroseptal and inferolateral segments.
The cardiac mass measurements revealed good correlation between MRI and echocardiogram (r: 0.92),
as shown in Fig. 1 .
MRI assessment of EDV correlated well with measurements acquired with echocardiogram (r: 0.81),
but volumes measured by MRI were slightly overestimated with wider limit of agreement (SD: 11ml).
The EF measurements proved to correlate well (r: 0.85) between the two techniques with narrower limit of agreement (SD: 4.7%) and minimal bias (1.6% ) with MRI,
as demonstrated in Fig. 2 .
