Right Ventricular Hypertrophy

Right ventricular hypertrophy (pronounced: rait ven-trik-yuh-lar hahy-per-truh-fee) is a medical condition characterized by the thickening of the myocardium (heart muscle) in the right ventricle of the heart.

Etymology

The term "Right ventricular hypertrophy" is derived from the Latin words 'dexter' meaning right, 'ventriculus' meaning small belly or cavity, and the Greek word 'hypertrophia' meaning excessive nourishment.

Definition

Right ventricular hypertrophy is a condition where the muscle wall of the right ventricle of the heart becomes thickened. This is often a response to increased resistance or high blood pressure in the pulmonary arteries, which the right ventricle pumps blood into.

Symptoms

Symptoms of right ventricular hypertrophy may include shortness of breath, chest pain, dizziness, and syncope (fainting).

Causes

The most common cause of right ventricular hypertrophy is pulmonary hypertension, which is high blood pressure in the arteries that supply the lungs. Other causes can include congenital heart disease, pulmonary embolism, and chronic lung disease.

Diagnosis

Diagnosis of right ventricular hypertrophy is typically made through echocardiography, which uses sound waves to create images of the heart. Other diagnostic tests may include electrocardiogram (ECG), cardiac MRI, and right heart catheterization.

Treatment

Treatment for right ventricular hypertrophy typically involves addressing the underlying cause. This may include medications to lower blood pressure, procedures to repair or replace damaged heart valves, or surgery to correct congenital heart defects.
