Aims and objectives
Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in selected patients with heart failure (HF); however approximately one third of the implanted patients do not show any benefit from this treatment [1,2].
Thus a number of devices are implanted without any recognized clinical benefit; this has important implications for health costs,
as well as exposing patients to unnecessary risks [10]. Indication to this treatment is still based mainly on electric parameters [3-9] .
In order to evaluate any predictors of outcome,
the left ventricle has been extensively studied in these patients,
including volumes,
function and scar [11-13,19-21],
while the right ventricle (RV) assessment is often neglected.
Cardiovascular magnetic resonance (CMR) is considered the gold standard technique for the RV function evaluation,
providing,
with high reproducibility,
an accurate assessment of the morfology,
volumes and wall motion [14-18].
Therefore the purpose of this study was to evaluate the impact of the RV systolic dysfunction,
assessed by CMR,
in the response to CRT in patients with non-ischemic dilated cardiomyopathy (DCM).
