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.
在2例患有流入道室间隔缺损且三尖瓣隔叶腱索横跨至二尖瓣后内侧乳头肌及左心室副乳头肌的患儿中，分别将横跨腱索与后内侧乳头肌的楔形部分及副乳头肌的顶部切除。在室间隔缺损补片修补后，带有腱索组的乳头肌段被固定于右心室间隔，从而使三尖瓣功能正常。与传统修复技术不同，当横跨腱索插入二尖瓣乳头肌时，所报道的改良方法是适用的。此外，还避免了在不适当心室构建复杂挡板相关的各种缺点。
