Abstract:
We describe a novel chordal-sparing technique of mitral valve replacement using minimum number of artificial chordae tendineae in patients with rheumatic mitral stenosis. Continuity between the papillary muscles and mitral annulus is restored by placing two 3-0 expanded polytetrafluoroethylene mattress sutures: one for the anterior papillary muscle at the 9-10 o'clock position (as defined by mid-anterior annulus to be 0 o'clock) on the mitral annulus, and the other for the posterior papillary muscle at the 5-6 o'clock position.
