Mitral regurgitation is the most common form of mitral valve dysfunction. Today more than 2.5 million Americans are estimated to be affected by mitral regurgitation. This number is expected to double by the year 2030. Every year, 300,000 people worldwide undergo open heart surgery for mitral valve repair, 44,000 people in the US alone. [1]
