Right ventricular dysfunction
Right ventricular dysfunction usually results from either pressure overload, volume overload, or a combination.
It occurs in a number of clinical scenarios, including:
It can manifest as right heart strain.
Sustained right ventricular dilatation and hypertrophy can frequently progress to right ventricular failure.
Two dimensional echocardiography is usually considered the mainstay for analysis of right ventricular function.
- right ventricular wall can be thickened (>4 mm) (often observed in congenital heart disease) or dilated (in acquired heart disease)
- free wall may be hypokinetic; this is best appreciated on parasternal long axis projections
May have a role in assessment. Suggestive signs include:
- right ventricular dilatation (RVD) (RV/LV ratio, >0.9)
Several phenotypic patterns have been described .
