Normal structures in the ventricles that can mimic diseases and appropriate investigations to prevent misinterpretations.

Cardiac chambers	Normal structures	Mimickers	Remarks
Right ventricle	Displaced moderator band	Double chamber right ventricle	Further evaluation with echocardiogram or MRI
	Prominent moderator band	Tumor or thrombus	Re-evaluation on MPR
	Prominent anterior papillary muscle	Tumor or thrombus	Re-evaluation on MPR
	Non-specific fat deposition in the RV free wall	Arrhythmogenic Right Ventricular Dysplasia	Further evaluation with echocardiogram or MRI
Left ventricle	Prominent posterior papillary muscle	Tumor or thrombus	Re-evaluation on MPR
	Normal apical thinning	Prior myocardial infarction	Further evaluation with echocardiogram or MRI
	Membranous septum	VSD	Further evaluation with echocardiogram or MRI
