Pulmonary balloon dilation, also known as balloon pulmonary valvuloplasty or balloon dilation, is a procedure used to treat narrowed areas in the pulmonary valve or other parts of the pulmonary artery. This narrowing, called stenosis, can restrict blood flow from the heart to the lungs, leading to various symptoms and complications.

A thin, flexible tube with a small balloon at its tip, called a balloon catheter is used for the procedure.The catheter is inserted into a blood vessel, usually in the groin or arm, and guided through the blood vessels to the narrowed area of the pulmonary valve or artery.Once in place, the balloon is carefully inflated to stretch and widen the narrowed area, improving blood flow.Narrowing in the pulmonary arteries can also be treated with balloon dilation to improve blood flow and reduce symptoms.

pulmonary balloon dilation is a minimally invasive and effective procedure used to treat narrowed areas in the pulmonary valve or artery, improving blood flow and relieving symptoms with a relatively quick recovery time.
