Replacing defective heart valves with prostheses in newborns is a difficult business, which is compounded by the fact that the new valves need to grow along with the children’s hearts. Two surgeons at Boston Children’s Hospital were faced with infants, one with severe mitral regurgitation and one with mitral stenosis, who required their mitral valves replaced.
To solve the problem, the physicians modified Medtronic‘s Melody transcatheter valve, that’s normally indicated for replacement of the pulmonary valve. The valves will be made to expand as the kids grow via catheterization with balloon dilatation, hopefully reducing the need for further surgeries. The successful implants in the two infants have been reported in The Annals of Thoracic Surgery.
