6.8K views · 23 reactions | Pediatric heart surgeon, Dr. David Kalfa, explains a new technique for mitral valve replacement in children. What's so exciting about this? The valve grows as the child grows. Using the Melody Valve in the mitral position allows surgeons to make the valve bigger and bigger over time without additional open-heart surgeries. The high-riding implantation cuts back on side effects and may avoid reoperations. #CHD | Columbia Surgery | Facebook
