Balloon dilatation is a minimally invasive transvenous procedure to dilate the pulmonary valve orifice during cardiac catheterisation. It is popular with patients as an alternative to surgery. It avoids a potentially painful operation and usually the patient can return to normal life within a day or two instead of needing several months’ convalescene.
This procedure is used to treat pulmonary valve stenosis. Pulmonary valve stenosis is narrowing of the pulmonary valve in the heart. It is usually congenital.
This procedure is done to widen narrowed (stenotic) blood vessels and heart valves. In a balloon dilation procedure, the physician uses a catheter equipped with a special balloon device at its tip. The balloon device is inflated when it reaches the narrowed vessel or heart valve to widen the opening to improve blood flow. Conditions treated with balloon dilation include:
- Aortic valve stenosis
- Branch pulmonary artery stenosis
- Coarctation of the aorta
- Pulmonary stenosis
