Papillary Muscle
Influence of procedural differences on mitral valve configuration after surgical repair for functional mitral regurgitation: in which direction should the papillary muscle be relocated?
... The mitral valve was exposed through a right-sided left atriotomy. U-shaped 2-0 braided simple horizontal sutures were placed at the annulus to optimize the exposure of the subvalvular apparatus. Polytetrafluoroethylene ...
