In a prospective series of 300 consecutive patients referred for a two-dimensional echocardiogram, the presence of left ventricular false tendons was searched. The diagnosis of a false tendon was made when a clear linear echo was continuously observed within the left ventricular cavity from the septum to the free wall or to a papillary muscle. Using this criterion, a false tendon was detected in 9 of the 300 patients (incidence of 3%), frequently from an apical position. The precise sites of attachment of the false tendons were observed by slight rotation and/or angulation of the transducer from the classic views: the septum and the lateral papillary muscle were the most frequent sites of attachment. Associated congenital heart disease was present in only 1 patient. Most patients had moderate symptoms and a soft musical systolic murmur. Three patients had premature ventricular contractions disappearing with exercise. The possible relations of LV false tendons with a musical murmur, arrhythmia or abnormal LV geometry are discussed.
在一系列连续300例接受二维超声心动图检查的前瞻性研究患者中，探寻左心室假腱索的存在情况。当在左心室内从室间隔到游离壁或到乳头肌持续观察到清晰的线性回声时，即可诊断为假腱索。采用这一标准，在300例患者中有9例检测到假腱索（发生率为3%），假腱索常起源于心尖位置。通过将探头从经典视图进行轻微旋转和/或角度调整来观察假腱索的精确附着部位：室间隔和外侧乳头肌是最常见的附着部位。仅1例患者伴有先天性心脏病。大多数患者有中度症状和柔和的音乐样收缩期杂音。3例患者有室性早搏，运动后消失。讨论了左心室假腱索与音乐样杂音、心律失常或左心室几何形态异常之间可能的关系。
