Mechanical properties of myxomatous mitral valves.

OBJECTIVE We sought to characterize the mechanical properties of normal and myxomatous mitral valve tissues. METHODS We tested 113 mitral valve sections from patients undergoing mitral valve repair or replacement for myxomatous mitral valve prolapse and sections from 33 normal valves obtained at autopsy. RESULTS Myxomatous mitral valve leaflets were… CONTINUE READING
