Table 1 Criteria for diagnosing right ventricle dilation at point-of-care bedside echocardiography

Echocardiography view	Criteria for right ventricle dilation
4-Chamber apical view	Right/left ventricular end-diastolic diameter ratio >0.9
Parasternal long axis view	Right ventricular end-diastolic diameter >30 mm
Subcostal view	Right/left ventricular end-diastolic diameter ratio >0.7 or 0.9

For the evaluation of the dimension of the right ventricle the preferred view should be the apical 4-chamber. The other views should be used as second choice in case of doubtful measure or impossibility to obtain a clear image
