“…A report by Mukai et al (1991) provides an example of a hemodynamic complication incurred by a rupture of an FT. In that case, a ruptured FT, secondary to dilated cardiomyopathy, served as a peduncle for a mobile left ventricular thrombus.…”

False tendons: An endoscopic cadaveric approach

False tendons (FTs) have been extensively described and recognized by gross anatomic studies. However, in the clinical setting the recognition of FTs is limited to the use of echocardiography. We examined 200 formalin fixed adult hearts, with gross dissections. In addition, 90 of these specimens were also examined with ultrasonographic and endoscopic techniques. Gross examination was able to identify FTs in 128 (62%) specimens. The total number of FTs observed, was 248 and was classified into five types according to their location. In Type I (92, 37.1%) the FT was located between the posteromedial papillary muscle and the ventricular septum. In Type II (55, 22.1%) the FT was located between the two papillary muscles. Type III (41, 16.5%) was classified as an FT between the anterolateral papillary muscle and the ventricular septum. The FT in Type IV (31, 12.5%) was observed to connect between the ventricular septum and the free wall and lastly in Type V (29, 11.6%) the FTs were found to be weblike with three or more points of insertion. When using all three techniques (n = 90), gross dissection and endoscopy were able to identify FTs in 62.2% of specimens while echocardiographic imaging was only able to identify FTs in 27.7% of specimens. Of the 114 FTs detected grossly and endoscopically, echocardiography was only able to identify 46 (40.3%). Therefore, the overall sensitivity of echocardiography for detecting left ventricular FTs was only 40.3%, compared to 100% for endoscopy. Based upon the ability or lack thereof of echocardiography to detect certain topographical patterns, we have created a small series of subtypes for the FTs. Histologically, in 30% of the FTs, conduction tissue fiber was observed to be present, which may implicate them in the appearance of arrhythmias.

“…In those who undergo heart surgery or left ventricular catheter ablation, the presence of LVFT must be known by the operator to avoid damage to these tendons, in view of the possible presence of the conduction system and coronary artery branches in the tendons [2]. As well as, because LVFTs can be the origin of the infective endocarditis [8, 17] and cavitary thrombus [18, 19], clinician must be vigilant in those who have unknown source of fever or systemic embolism.…”

Left ventricular false tendons (LVFTs) are linear fibrous or fibromuscular bands stretching across left ventricular cavity. Although LVFTs have been associated with various heart pathologies and investigated embryologically and histologically, there is only one report in the literature connoting possible hereditary transmission of this entity. We reported a father and his daughter having similar types of LVFTs with regard to location and thickness. With this report, we will contribute in the literature in respect to potential genetic inherence of LVFTs.

“…A thrombus attached to an intact LV false tendon has rarely been reported perhaps due to the poor sensitivity of 2DTTE for detection . Although the incidence of false tendons detected by echocardiography range from <1% in early series to 40.5% in recent studies, they are found at autopsy in approximately one‐half of normal and abnormal hearts, particularly patients with LV dilatation and systolic dysfunction .…”

Three‐dimensional echocardiography demonstrates a skewered left ventricular thrombus in a patient with a heart transplant

et al. 2018

A left ventricular (LV) false tendon is a frequently visualized structure in echocardiography with unclear clinical significance. We present the case of a false tendon serving as a nidus for thrombus in a post‐orthotopic heart transplantation patient. Three‐dimensional transthoracic echocardiography (3DTTE) was utilized to visualize a LV mass and facilitate its identification as a thrombus as well as the surrounding structures. Using datasets from 3DTTE, the lack of ventricular wall attachment and circumferential formation of the thrombus around the false tendon was identified. Serial imaging demonstrated resolution of the thrombus with anticoagulation.
