Multimodality CMR diagnosis of double-chambered left ventricle in a child: A case report

When DCLV presents with an ambiguous apical mass and abnormal cavity with complex comorbidities, it can mimic serious conditions such as LVNC, thrombus, aneurysm, or diverticulum, making accurate diagnosis challenging using echocardiography alone. In situations where echocardiographic findings are inconclusive, CMR with tissue characterization is essential to avoid misdiagnosis and unnecessary treatment. Early use of multimodality CMR in such cases helps to clarify morphology and guide clinical management.
