| Popis: | PURPOSE An accurate evaluation of left ventricular volumes, mass, and ejection fraction (EF) and an early exclusion or detection of significant coronary artery disease or cardiac allograft vasculopathy are mandatory for clinical management and prognosis assessment of heart-transplanted patients (HTP). The purpose of this article was to evaluate the role of dual-step prospective electrocardiography-triggered Dual-Source CT (pECGdual-step-DSCT) in HTP for the assessment of left-ventricular function, in comparison with echocardiography (echo) and cardiac magnetic resonance (CMR) performed on the same day, and of the coronary arteries as well. MATERIALS AND METHODS Left-ventricular EF, end-diastolic volume, end-systolic volume, stroke volume, cardiac output (CO), and mass were assessed in 11 HTP by pECGdual-step-DSCT in comparison with CMR and echo performed on the same day. During all the examinations, the heart rate was recorded. CT coronary artery assessment was also performed. RESULTS Heart rate was lower during DSCT (75.6±7.8 bpm; P |
