Aims and objectives
Cardiac CT has been introduced in clinical practice as a valuable tool for non-invasive evaluation of coronary anatomy,
especially in heart failure settings (Class IIb indication in 2016 ESC Guidelines).
Moreover cardiac CT has been recently described as a useful tool for a comprehensive assessment of cardiac anatomy and function,
other than the sole evaluation of coronary anatomy.

Methods and materials
A consecutive cohort of patients with newly diagnosed LVD (left ventricular disfunction) (LVEF<50%) and clinical indicated MRI will be screened.
Exclusion criteria will be contraindications to contrast agents and impaired renal function (creatinine clearance <60 ml/min).
Cardiac CT will be performed per protocol within ±10 days from MRI.
CCTAs will be performed with last generation CT scanner with whole heart coverage and gantry rotation time of 280 msec.
A first CT scan will be performed...
40 patients have been enrolled form January 2018 and September 2018.
Biventricular volumes and ejection fractions (EFs) were similar when evaluated at CT and CMR.
left ventricle EF was similar between CT (35.9 ± 9.7%) and MRI (35 ± 9.8%,
Right ventricle end diastolic volume (EDV) was slightly overestimated by CT (178.7 ± 55.7 mL vs.
155.4 ± 54.1 mL,
Thirty patients showed late enhancement (LE) consistent with myocardial fibrosis at...
Cardiac CT appears to be feasible and accurate in the evaluation of newly diagnosed LVD in comparison with CMR and can be considered as an alternative technique in patients with contraindication to MRI.
Radiation dose for fibrosis assessment alone was negligible (0.84 ± 0.2 mSv).
