What causes dilation of right ventricle?

RV dilation can be caused by a broad range of diseases including conditions such as volume load or pressure load of the RV, RV cardiomyopathies, or RV infarction. Different imaging techniques can contribute to the assessment of RV structure, RV volumes, and function.

What is meant by mildly dilated?

Mildly dilated congestive cardiomyopathy (MDCM) has been defined as end-stage heart failure of unknown etiology (New York Heart Association class IV, left ventricular ejection fraction less than 30\%), occurring with neither typical hemodynamic signs of restrictive myopathy nor significant ventricular dilatation (less …

How is right ventricular dilation treated?

Drugs that are used to treat heart failure and dilated cardiomyopathy include: Angiotensin-converting enzyme (ACE) inhibitors. This type of medicine widens blood vessels (vasodilator) to lower blood pressure, improve blood flow and decrease the heart’s workload. ACE inhibitors may improve heart function.

What does it mean if a ventricle is dilated?

Dilated cardiomyopathy is a disease of the heart muscle that usually starts in your heart’s main pumping chamber (left ventricle). The ventricle stretches and thins (dilates) and can’t pump blood as well as a healthy heart can. Over time, both ventricles may be affected.

What does the right ventricle do?

The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.

Is Right ventricular hypertrophy fatal?

The main complications associated with RVH are caused by the unnecessary stress it places on the heart. If it is not treated, RVH can result in a weakened heart and can heighten the risk of heart failure and cardiovascular death in some people.

Does the right ventricle carry oxygenated blood?

The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
