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
