What is it?

Double-outlet right ventricle is a heart condition present at birth (congenital) in which two large blood vessels don't connect to the heart normally. In infants born with this condition, the main artery that carries blood from the heart to the body (aorta) and the artery that directs blood from the heart to the lungs (pulmonary artery) connect partially or completely to the right lower heart chamber (ventricle). Sometimes these blood vessels are also reversed from their normal positions.
In infants with double-outlet right ventricle, there's also a hole between the right and left ventricles (ventricular septal defect). This causes oxygen-rich blood to mix with oxygen-poor blood. Children born with double-outlet right ventricle can have a lower than normal amount of oxygen in the bloodstream.

Signs & symptoms

Signs and symptoms could include:
* Pale gray or blue lips, tongue or fingernails (cyanosis)
* Rapid breathing
* Swelling in the legs, belly or areas around the eyes
* Shortness of breath during feedings, leading to poor weight gain


Doctors will generally perform an echocardiogram to diagnose double-outlet right ventricle and any associated defects. Echocardiograms use sound waves to produce an image of the heart. Sound waves bounce off the heart and produce moving images that can be viewed on a video screen.
If more information is needed, doctors may conduct cardiac CT and MRI scans or cardiac catheterization. In cardiac catheterization, your child's doctor inserts a thin, flexible tube (catheter) into an artery or vein in the groin or neck and threads it into the heart. A dye is injected through the catheter to make the heart structures more visible on X-ray pictures. Cardiac catheterization also measures pressure and oxygen levels in the chambers of the heart and in the blood vessels.


Several types of surgery may be performed, depending on the specific heart defect and any associated defects.
