RVH usually occurs due to chronic lung disease or structural defects in the heart. One of the most common causes of RVH is pulmonary hypertension (PH), defined as increased blood pressure in the vessels supplying blood to the lungs. PH leads to increased pulmonary artery pressure. The right ventricle tries to compensate for this increased pressure by changing its shape and size. Hypertrophy of individual myocytes results in an increase in right ventricular wall thickness.
