Abstract
A 33 years asymptomatic hypertensive male underwent a routine color echocardiography for assessment of overall cardiac anatomy, left ventricle (LV) regional wall motion abnormality , LV wall thickness, systolic and diastolic functions. A striking echodense vertical band was visualized in the LV while visualizing the apical two, three and four chamber views. Nevertheless, despite its anatomic location, there was no evidence that the anamolous mitral valve chordae tendineae was causing any regurgitation of mitral valve or obstruction to left ventricular outflow tract (LVOT). To the best of our knowledge this is the first case report of chordae attachment to the LV apex.
Keywords: Aberrant mitral valve chordae tendineae, abnormal mitral valve apparatus, 4D X Strain Echocardiography.
