Herzzentrum, University of Leipzig, Germany.

In 2 children with an inlet ventricular septal defect and straddling chordae tendineae of the septal leaflet of the tricuspid valve to the posteromedial papillary muscle of the mitral valve and to an accessory papillary muscle in the left ventricle, the straddling chordae were excised with a wedge of posteromedial papillary muscle and with the top segment of the accessory papillary muscle, respectively. After patch closure of the ventricular septal defect, the papillary muscle segment with its group of chordae was anchored to the right ventricular septum 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 mitral valve. In addition, various disadvantages related to the construction of a complex baffle in the inappropriate ventricle are avoided.

D002815	Chordae Tendineae	The tendinous cords that connect each cusp of the two atrioventricular HEART VALVES to appropriate PAPILLARY MUSCLES in the HEART VENTRICLES, preventing the valves from reversing themselves when the ventricles contract.	Tendineae, Chordae
D006345	Heart Septal Defects, Ventricular	Developmental abnormalities in any portion of the VENTRICULAR SEPTUM resulting in abnormal communications between the two lower chambers of the heart. Classification of ventricular septal defects is based on location of the communication, such as perimembranous, inlet, outlet (infundibular), central muscular, marginal muscular, or apical muscular defect.
