This week we review a recent surgical paper on the 'off-label' use of the Melody valve for replacement of the AV valve in small infants and children. How effective and safe was this procedure? What factors were associated with the need for reintervention and what sorts of reinterventions were most common? Why was catheter based reintervention rarely employed? What sort of anti-coagulation protocol seems best to protect these valves? Assistant Professor of Pediatrics at the University of Nebraska, Dr. Samantha Gilg shares the insights from her work this week.
