Abstract:
To review the imaging characteristics and evaluate the diagnostic value of echocardiography for congenital double‐chambered left ventricle ( DCLV ) in children , and improve the diagnostic accuracy of initial echocardiography . Methods Doppler echocardiography was performed and these images were compared retrospectively with operative and computed tomography angiography findings in 8 children with DCLV . Results DCLV was characterized by the presence of a main left ventricular chamber and an auxiliary chamber seperated by abnormally hypertrophic muscle and/or fiber bundles . Six cases were diagnosed with type A ,and 2 cases with type B by Li Jun′s classification . T he associated malformations included ventricular septal defect ( 3 cases ) ,mitral regurgitation ( 2 cases ) ,mitral valve stenosis ( 1 case) . Six of 8 cases( 75 .0% ) were diagnosed correctly using Doppler echocardiography ,in the remaining 2 cases ( 25 .0% ) ,1 case was missed ,1 case misdiagnosed as left ventricular diverticulum . Conclusions DCLV could be correctedly diagnosed by Doppler echocardiography . This malformation should be differentiated from left ventricular diverticulum , left ventricular aneurysm , left ventricular non‐compaction ,and ventricular septal defect .
