Understanding this service
Balloon valvuloplasty, also called balloon valvotomy, is used to open a heart valve that has become too narrow. A catheter carrying a deflated balloon is guided to the valve; the balloon is inflated for a short time to widen the opening and is then removed.
The source heart-valve page notes that selected narrowed mitral valves can be treated with balloon dilation without surgery. Balloon treatment may also be considered for other valve stenoses in carefully selected patients. Echocardiography is central to confirming severity and deciding whether valvuloplasty, surgery or another catheter treatment is appropriate.
When is it recommended?
- Significant valve stenosis confirmed by echocardiography
- Selected mitral stenosis with anatomy suitable for balloon dilation
- Selected pulmonary valve stenosis
- Selected aortic-valve stenosis when a specialist team considers balloon treatment appropriate
- Symptoms or heart effects that make treatment of the narrowed valve necessary
Purpose and potential benefits
- Widens a narrowed valve opening and improves blood flow
- Uses a catheter rather than an open-chest operation
- May relieve symptoms or delay valve replacement in selected patients
- Offers a treatment option when the valve anatomy and clinical situation are suitable
