The right atrium value in patients operated for tetralogy of Fallot

Background Left atrium enlargement is directly proportional to the severity of underlying clinical (or subclinical) cardiovascular disease. Right atrium (RA) measurements are not routinely performed despite their prognostic value has been demonstrated in chronic heart failure, atrial and pulmonary arterial hypertension. The aim of the study was to evaluate RA dimensions and volumes by cardiac Magnetic Resonance (CMR) in a large cohort of operated Fallot (opTF) compared to a control group, and correlate the RA size to traditional prognostic parameters and clinical events.
