Abstract

Obtaining excellent exposure of the papillary muscles is challenging in minimally invasive mitral valve repair. We have developed a simple and effective technique using a sterile paper ruler. The ruler is cut to the proper length (8 to 12 cm) depending on the valve size, then rolled and sutured. The rolled ruler, 7 to 11 cm in circumference, is placed inside the mitral leaflets. This technique provides excellent exposure of the papillary muscles without damaging the leaflets and prevents chordal injury during artificial chordal implantation.
