If there are no other heart abnormalities, people with the condition may not have symptoms throughout life, although this is very rare.
Most often, the constant stress on the right ventricle weakens the ventricle and its tricuspid value. Regurgitation (leaking backwards) of the tricuspid valve produces a characteristic heart murmur, and congestive heart failure may develop due to the weakened pumping action of the right ventricle.
Corrected transposition of the great arteries is often discovered due to symptoms that accompany other common heart defects present with this condition.
