SUSPENSION OF STRADDLING TRICUSPID-VALVE CHORDAE INTO THE APPROPRIATEVENTRICLE

In 2 children with an inlet ventricular septal defect and straddling c hordae tendineae of the septal leaflet of:he tricuspid valve to the po steromedial papillary muscle of the mitral valve and to an accessory p apillary muscle in the left ventricle, the straddling chordae were exc ised with a wedge of posteromedial papillary muscle and with. the top segment of the accessory papillary muscle, respectively. After patch c losure all the ventricular septal defect, the papillary muscle segment with its group of chordae was anchored to the right ventricular septu m with resulting competence of the tricuspid valve. in contrast to the traditional repair technique, the reported modification is applicable when the straddling chordae insert into a papillary muscle of the mit ral valve, in addition, various disadvantages related to the construct ion of a complex baffle in the inappropriate ventricle are avoided.
