Isolated foetal left ventricular apical hypoplasia: would you know how to spot it?

Isolated left ventricular apical hypoplasia is a rare cardiac malformation. This entity is easily diagnosed if its key features are recognised, but will puzzle the clinician who is not aware of its existence. It is characterised by echocardiographic findings of a spherical left ventricle, an elongated right ventricle wrapping around the deficient left ventricular apex, and abnormal papillary muscles' origin.
