Right ventricular atrophy is an antonym for left ventricular hypertrophies, referring to a condition where the right ventricle of the heart becomes abnormally small, weakened, or underdeveloped. This opposite condition can arise due to a variety of causes, such as pulmonary embolism, chronic obstructive pulmonary disease, pulmonary hypertension, or congenital heart defects that affect the right side of the heart. Patients with right ventricular atrophy may experience symptoms such as shortness of breath, chest pain, fatigue, and impaired exercise tolerance. Diagnosis can involve electrocardiograms, echocardiography, cardiac CT or MRI imaging, and treatment may require medications, lifestyle changes, or surgery depending on the underlying cause of the condition.
