Sizing of ring or band using non-resection neo-chordal technique is different than classic resection methods. Neo-chord length determination can be problematic and multiple approaches have been described. The video demonstrates a simple and easily reproducible technique of both ring/band sizing and neo-chord adjustment under ventricular loading.
During the last five years the demonstrated method of ring/band sizing and adjustment of neo-chords has been used at our center with consistent results and without instances of mitral stenosis or SAM.
