title: [Surgical topography of the membranous part of the interventricular heart septum].
abstract: An investigation of the membranous part of the interventricular septum of the heart during operations and an autopsy material has shown the shape and size of this structure of the heart to be variable and to have complex interrelations with many components of the heart. The ventricular portion of this part of the septum is always covered in some extent with chordae, threads of the tricuspid valve and its anterioseptal commissure. The atriotomic access may be an alternative to the surgical access via the right ventricle, but in this case it is necessary to dissect or cut off the septal cusp from the valve.
