Vimala LR, et al. – Via performing a study involving adults with repaired truncus arteriosus (rTA), researchers investigated cardiovascular MRI (CMR) features in rTA. They also examined links between imaging findings and cardiovascular outcomes in these individuals. Participants included 27 adults (median age at cardiovascular magnetic resonance: 26 years). The observation period was 5.2 years. In all, they found that cardiac chamber measurements were within the normal range, except for mildly increased RV mass. In subtypes, a difference was seen only in pulmonary artery peak velocity in CMR measurements (highest in subtype 3, 318 ± 26 cm/s). There was a moderate correlation of the number of cardiovascular interventions in adulthood, with left ventricular end-diastolic volume, left ventricular ejection fraction, and neoaortic root size. Furthermore, five patients experienced cardiovascular events (non-mutually exclusive) that included death (n = 1), heart failure (n = 1), ventricular tachycardia (n = 1), and atrial tachycardia (n = 3). In rTA, adverse events were reported in correlation with reduced right ventricular ejection fraction and smaller ascending aorta on cardiovascular magnetic resonance.
