In double-outlet right ventricle, the lower right heart chamber, called the right ventricle, has two openings for blood to exit instead of one. Some blood goes to the body instead of just the lungs. There also is a hole between the two lower heart chambers. The hole is called a ventricular septal defect. In a typical heart, shown on the left, the pulmonary artery connects to the right ventricle and the aorta connects to the left ventricle.
