Video 14.12 A short-axis plane from a subxiphoid window in typical congenital mitral stenosis
A short-axis plane from a subxiphoid window in typical congenital mitral stenosis. Well-spaced papillary muscle groups are readily appreciated in this short-axis plane � excluding parachute mitral valve morphology (see Video 14.13). Note that the orifice appears falsely adequate in the short-axis view, due to the relationship of the distal aspect of the leaflets to the orifice � the leaflet adjacent to the orifice runs nearly parallel to the orifice. This aspect of the anatomy is only appreciated in orthogonal views (apical 4-chamber, see Video 14.10).
