Body was changed:

Right ventricleventricular dysfunction can usually results from either pressure overload, volume overload or a combination. 

It occur in a number of clinical scenarios.

This include

It can manifest as right heart strain.

Pathology

Sustained ventricular dilatation and hypertrophy can frequently progresses to RV failure.

Radiographic features

Echocardiography

Two dimensional echocardiography usually considered the mainstay for analysis of RV function. 

Features include

Right ventricular wall can be thickened (> 4 mm) (often observed in congenital heart disease) or dilated (in acquired heart disease).

The free wall can be hypokinetic, and is best appreciated from parasternal long axis projections.

CT

May have a role in assessment

Suggestive signs include

  • RVD (RV/LV ratio, >1.0) 5
Cardiac MRI

Several phenotypical pattern have been described 9.

  1. pressure overload
  2. volume overload
  3. volume overload plus left ventricular dysfunction: considered 2nd commonest pattern
  4. depressed biventricular function: considered commonest pattern
  5. mixed overload, as there is co-existing biventricular dysfunction (in different degrees depending on disease duration), dilatation and right ventricular hypertrophy
