BALLOON VALVOTOMY
Home > Services > Balloon Valvotomy
Balloon valvotomy, also known as balloon valvuloplasty, is a highly effective, minimally invasive procedure used to treat narrowed or stiffened heart valves (valvular stenosis). When a heart valve becomes thick, scarred, or calcified, its flaps (leaflets) fuse together and fail to open fully. This restricts healthy blood flow and forces the heart to work much harder, leading to shortness of breath, chest pain, and heart failure. Using a specialized catheter with a tiny, incredibly strong balloon at its tip, interventional cardiologists can safely stretch and separate the fused valve leaflets. This rapidly restores normal blood flow and instantly relieves symptoms without the need for open-heart surgery.
1. Indications:
Balloon valvotomy is recommended for patients diagnosed with significant narrowing of one of the heart’s valves, provided the valve is not already heavily leaking (regurgitating). Common indications include:
- Severe Mitral Stenosis, frequently caused by a history of rheumatic fever, which leads to fluid buildup in the lungs and extreme shortness of breath
- Pulmonary Stenosis, a narrowing of the valve between the heart and the lungs that is often present from birth (congenital)
- Severe Aortic Stenosis in frail or elderly patients, used as a temporary symptom-relieving “bridge” to a permanent valve replacement (such as TAVR or surgery)
- Significant fatigue, chest tightness, fainting spells, or inability to exercise due to a restricted heart valve
- Pregnant women with severe mitral stenosis who require urgent, safe symptom relief to carry their pregnancy to term
- Patients who are considered too high-risk for traditional open-heart valve replacement surgery
By safely widening the valve, patients experience an immediate improvement in breathing, energy levels, and overall cardiac function.
2. Procedure:
A balloon valvotomy is performed in an advanced cardiac cath lab under local anesthesia and mild sedation. You will remain awake and relaxed throughout the process. A small puncture is made in a major blood vessel in the groin (usually the femoral vein).
Through this access point, a thin, flexible catheter is gently navigated up to the heart. The cardiologist uses continuous X-ray imaging (fluoroscopy) and often a real-time ultrasound of the heart (Echocardiogram) to precisely track the catheter’s position. Once the catheter reaches the narrowed valve, a microscopic guidewire is carefully threaded directly through the stiff valve opening.
A specialized catheter fitted with a deflated balloon is then advanced over the wire and positioned exactly across the fused valve leaflets. The doctor firmly inflates the balloon for just a few seconds. The outward pressure of the balloon gently stretches the valve opening, separates the fused tissue, and cracks hardened calcium. The balloon is immediately deflated and removed, leaving the valve widened and functioning much more naturally. The procedure typically takes 1 to 2 hours, and most patients are able to return home within a day or two.
3. Safety:
Balloon valvotomy is a safe, well-established, and highly successful procedure when performed by an expert interventional cardiologist. Because it completely avoids a major chest incision and the need for a heart-lung bypass machine, recovery is significantly faster and far less painful than traditional open-heart surgery.
Continuous monitoring of your vital signs, heart rhythm, and oxygen levels is strictly maintained throughout the procedure. Possible but uncommon risks include:
- Bleeding, bruising, or a hematoma at the catheter insertion site in the groin
- Creation of a new valve leak (regurgitation) if the valve fails to close tightly after being stretched
- Irregular heartbeats (arrhythmias) during catheter manipulation, which usually resolve on their own
- In rare cases, severe tearing of the valve leaflets requiring emergency surgical repair
- Blood clot formation or stroke (a small risk that is carefully managed with blood-thinning medications)
- Infection at the puncture site
