In 91 of 1007 children (9%) with and without heart disease who underwent echocardiographic exploration we found false chordae tendineae in the left ventricle. These bands, usually running from the lateral wall to the interventricular septum, showed strong ultrasound reflections and could be seen in at least two different views. More than one band was rarely seen in the ventricle. All children with false chordae tendineae in the left ventricle had innocent heart murmurs. Of these systolic murmurs 91% were, according to their sound quality, maximal intensity and frequency, Still's innocent murmurs. On the other hand, in 72% of 54 other children with innocent murmurs we found false chordae tendineae in the left ventricle by careful 2D-echocardiographic exploration.
在1007例接受超声心动图检查的儿童中，无论有无心脏病，有91例（9%）在左心室发现假腱索。这些条索通常从侧壁延伸至室间隔，表现为强烈的超声反射，至少可在两个不同视图中看到。在心室中很少见到不止一条条索。所有左心室有假腱索的儿童均有无害性心脏杂音。根据其音质、最大强度和频率，这些收缩期杂音中91%为史迪尔无害性杂音。另一方面，在另外54例有无害性杂音的儿童中，经仔细二维超声心动图检查发现，72%的儿童左心室有假腱索。
