Figure 2 Schematic showing the distribution of the chordal force transducers and the papillary muscle adjustments in normal (N), apical (A), posterolateral (PL) and apical posterolateral (APL) directions. Eight papillary muscle settings were tested. Scaled photograph of the transducer: 1 unit = 1 mm. CT_AA = chorda from the anterolateral papillary muscle (APM) to anterior leaflet; CT_AP = chorda from APM to posterior leaflet; CT_PA = chorda from the posteromedial papillary muscle (PPM) to anterior leaflet; CT_PP = chorda from PPM to posterior leaflet; AL = anterior leaflet.
