| Summary: | Introduction: Left Ventricular False Tendons (LVFT) are normal
and common anatomical variants of the left ventricle. They may
be associated with findings of cardiac pathology or they may be
an isolated finding from 2D echocardiogram. These structures
may mimic pathologic structures, such as intraventricular chorda
rupture, vegetation or thrombus, but considered as false tendon.
Aim: To study the morphology, age and gender specific
proportions of false tendons in cadaveric heart specimens.
Materials and Methods: A descriptive cross-sectional study was
conducted in Mysore Medical College and Research Institute,
Mysuru, Karnataka, India, from October 2015 to March 2017.
A total of 100 human cadaveric heart specimens of both males
(n=50) and females (n=50) aged 18-76 years were collected
from Department of Anatomy and postmortem specimens from
Department of Forensic Medicine. The morphology of tendons
was studied regarding its location, gross appearance and
parameters such as its length and width. The statistical analysis
was done using Chi-square test and Analysis of Variance (ANOVA)
test appropriately using the software Statistical Package for
Social Service (SPSS), version 20.0 for windows.
Results: False tendons were seen in 49 of heart specimens. Total
40 of the specimens showed one LVFT and nine showed two
LVFT. Out of total 44 (58.67%) specimens aged 50 years or less
had false tendons, while in older specimens, only 5 (20%) were
found to have false tendon (p-value <0.05). The common location
of false tendons was Posteromedial Papillary Muscle (PMPM)
to mid interventricular septum 11 (18.9%), followed by PMPM
to free wall 9 (15.5%). The tendons were fibrous in 53 (91.4%),
fibromuscular in 4 (6.9%) and 1 (1.7%) was muscular in nature.
Out of 50 female and 50 male heart specimens, 24 and 25 had
LVFT, respectively (p-value=0.891).
Conclusion: Sound knowledge of heart morphology can avoid
false diagnosis in patients with false tendon, as it can simulate
other pathological murmurs and structural heart disease in
echocardiography. |
