Isolated muscular ventricular diverticulum assessment using multi-parameter echocardiographic imaging: Case reports.

ABSTRACT

Ventricular diverticulum (VDi) is a rare and often asymptomatic congenital cardiac malformation detected incidentally as an outpouching on routine imaging examination, of which the muscular type has been less reported. Here, two patients were incidentally found to have outpouchings of the ventricle during routine transthoracic echocardiography. After a series of multi-parameter echocardiography examination, including two-dimensional (2D), three-dimensional (3D) photo-realistic rendering, blood speckle tracking (BST), and contrast enhancement, to provide morphological structure, spatial relationship, and blood flow information, both cases were finally diagnosed with muscular VDi. These cases highlight the advantages of using multi-parameter echocardiography for the comprehensive assessment of muscular VDi.
