Examination’s Book

CHAMBER SIZE

- look at in a number of views

- normally a crescent curving in front of LV.

- dilation may be due to: volume overload, failure, PHT, PE, TR, ASD, PR.

- failure: RV dilation, bulging of the interventricular septum, compressed LV, hypokinesis (mild, moderate, severe)

WALL THICKNESS

- RV hypertrophy from pressure overload

SYSTOLIC FUNCTION

- difficult to assess c/o shape and traberculations

- requires TOE

- RWMA is sensitive and specific for RV ischaemia or infarction

PULMONARY ARTERY PRESSURE

- some TR is normal

- RV systolic pressure = RAP + transtricuspid gradient (from peak tricuspid regurgitation velocity)

- in the absence of pulmonary stenosis, RVP = systolic PA pressure
