Cardiac magnetic resonance imaging and gadolinium angiography for neonates and small infants: a 10-year single institutional experience

Methods Clinical, anesthesia and nursing records of all patients (pts)<120 days of age who underwent CMR were reviewed. Variables including cardiac diagnosis, study duration, anesthesia type and agents used, prostaglandin E1 (PGE1) dependence and gadolinium (Gd) use were recorded. Serially recorded temperature, systemic saturation, and cardiac rhythm were analyzed. Primary outcome measure was any adverse event (AE) during or <24 hours after the procedure, including minor AE such as hypothermia (axillary temperature ≤95 F), desaturation (SpO2 drop ≥ 10% below baseline) and bradycardia (heart rate ≤100/ min). Secondary outcome measure was unplanned overnight hospitalization of out-pts.
