Complications

• Cyanosis
• Death
• Heart failure
• Leaking of blood back into the right ventricle (pulmonary regurgitation) after repair
• Right ventricular hypertrophy (enlargement)

Prognosis

About one-third of patients with mild stenosis get better, one-third stay the same, and one-third get worse. The outcome is good with successful surgery or balloon dilation. Other congenital heart defects may be a factor in the outlook.

Some valves can last for decades. Others wear out and will need to be replaced.
