A narrowed pulmonary valve also prevents a normal amount of blood from getting into the pulmonary arteries, so the lungs receive less deoxygenated blood than normal. There may also be a thickened right ventricle wall and an aorta that partially covers the ventricular septal defect.</figcaption> </figure> <p>This condition involves a ventricular septal defect and pulmonary stenosis. The pulmonary valve may also be small. The other two components are a thickened right ventricle wall and an aorta that is shifted towards the right side of the heart, over the ventricular septal defect. There is sometimes a patent ductus arteriosus through which blood flows from the aorta to the pulmonary arteries.</p><h2>What are the symptoms of Tetralogy of Fallot?</h2><p>Symptoms include a murmur. Sometimes, children experience a <a href="/Article?contentid=896&language=English">blue spell</a>. </p><p>Tetralogy of Fallot is diagnosed by way of a chest X-ray, an <a href="/Article?contentid=1276&language=English">electrocardiogram</a>, and an echocardiogram. Rarely, cardiac catheterization may be needed to confirm the anatomy prior to surgery. </p><h2>Treatment of Tetralogy of Fallot </h2><p>If the baby has had a blue spell, medications can help prevent further spells. Surgery will be needed, though not usually right after birth. This may involve putting in a shunt to help blood flow through the pulmonary arteries and closing the ventricular septal defect, or a complete repair. </p><h2>What are the outcomes of treatment for children with Tetralogy of Fallot?</h2><p>Repair of this defect is usually very successful. However, in some cases there may be a leaky pulmonary valve. This can take its toll on the right ventricle, and may require a valve replacement. In some cases, the pulmonary valve can narrow over time, requiring more surgery. <a href="/Article?contentid=890&language=English">Heart rhythm problems (arrhythmias)​</a> are also a potential risk. </p>Tetralogy of Fallot
