Double outlet right ventricle
Double Outlet Right Ventricle
Double Outlet Right Ventricle (DORV) is a congenital heart defect where both the pulmonary artery and the aorta arise from the right ventricle. Pronounced as "double outlet right ven-tri-kle", the term originates from the Latin words "duplex" meaning double, "exitus" meaning outlet, "dexter" meaning right, and "ventriculus" meaning little belly or ventricle.
Definition
In a normal heart, the aorta is connected to the left ventricle, and the pulmonary artery is connected to the right ventricle. In a heart with DORV, both of these arteries are connected to the right ventricle. This results in oxygen-poor blood being pumped to the body, leading to cyanosis or a bluish color of the skin, lips, and nails.
Symptoms
Symptoms of DORV can vary greatly depending on the specific anatomy of the heart. Common symptoms include shortness of breath, rapid breathing, poor feeding, and failure to gain weight. More severe symptoms can include cyanosis, fatigue, and heart failure.
Diagnosis
Diagnosis of DORV is typically made through echocardiography, a type of ultrasound that creates images of the heart. Other diagnostic tests may include a chest X-ray, electrocardiogram (ECG), and cardiac catheterization.
Treatment
Treatment for DORV typically involves surgery to correct the heart's anatomy. The specific type of surgery will depend on the individual's specific heart anatomy and may include a biventricular repair, univentricular repair, or heart transplant in severe cases.
Prognosis
With early diagnosis and appropriate treatment, the prognosis for individuals with DORV can be quite good. However, long-term follow-up care with a cardiologist is typically required.
