Right ventricular dysfunction
Updates to Article Attributes
Body
was changed:
Right ventricular dysfunction usually results from either pressure overload, volume overload, or a combination.
It occuroccurs in a number of clinical scenarios, including:
- pressure overload
- cardiomyopathies: ischaemic, congenital
- valvular heart disease
- arrhythmias
- sepsis
It can manifest as right heart strain.
Pathology
Sustained right ventricular dilatation and hypertrophy can frequently progressesprogress to right ventricular failure.
Radiographic features
Echocardiography
Two dimensional echocardiography is usually considered the mainstay for analysis of right ventricular function.
Features include
- 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
CT
May have a role in assessment. Suggestive signs include:
- right ventricular dilatation (RVD) (RV/LV ratio, >0.9) 5
Cardiac MRI
Several phenotypic patterns have been described 9.
- pressure overload
- volume overload
- volume overload plus left ventricular dysfunction: considered 2nd commonest pattern
- depressed biventricular function: commonest pattern
- mixed overload, as there is co-existing biventricular dysfunction (in different degrees depending on disease duration), dilatation and right ventricular hypertrophy
