INTRODUCTION:

Heart valves play a crucial role in the circulation of blood throughout our bodies. These valves open and close with each heartbeat, ensuring blood flows in the right direction. However, sometimes heart valves can become damaged or narrowed, which can lead to heart-related health issues. Valvular heart diseases (VHD) account for approximately 2–3% of cardiovascular disorders globally, with prevalence increasing with age. Traditional surgical valve repair or replacement, while effective, requires sternotomy, cardiopulmonary bypass, and prolonged recovery¹.

In high-risk surgical candidates, these factors limit access to life-saving treatment Valvuloplasty is an innovative and less invasive procedure used to repair these valves without the need for open-heart surgery⁷.

Advances in interventional cardiology have led to transcatheter valve therapies — procedures performed percutaneously using catheters introduced through peripheral vessels. These offer similar hemodynamic benefits with significantly reduced morbidity, hospital stay, and recovery time. In this article, we will delve into the world of valvuloplasty, its techniques, applications, and benefits².

Principles of Transcatheter Valve Interventions:

Catheter-based valve interventions aim to:

· Restore unidirectional blood flow.

· Preserve native valve structure when possible.

· Avoid open-heart surgery.

· Under fluoroscopic and echocardiographic guidance, devices are delivered through femoral or jugular access to the target valve site. Interventions include valve repair (e.g., clip, annuloplasty, balloon dilation) or valve replacement (deployment of a prosthetic valve inside native tissue)^3.

Types of Non-Surgical Valve Repair /Replacement Interventions:

Based on affected valve following are Types of Non-Surgical Valve Repair Interventions⁴

I. Aortic Valve:

· Transcatheter Aortic Valve Replacement (TAVR / TAVI)

· Balloon Aortic Valvuloplasty (BAV)

Most widely used intervention:

1. Transcatheter Aortic Valve Replacement (TAVR / TAVI)

Transcatheter Aortic Valve Replacement (TAVR) or Transcatheter Aortic Valve Implantation (TAVI) is a minimally invasive cardiac procedure designed to replace a diseased aortic valve without the need for open-heart surgery. It is primarily indicated for patients with severe aortic stenosis who are at high or prohibitive surgical risk due to age or comorbid conditions. In this technique, a collapsible bioprosthetic valve mounted on a metal stent is delivered to the heart through a catheter, most commonly via the femoral artery⁹. Once positioned within the native aortic valve, the new valve is expanded—either by balloon inflation or self-expansion—pushing the old leaflets aside and immediately restoring normal blood flow from the left ventricle to the aorta¹.

Several approaches can be used for valve delivery, including transfemoral, transapical, transaortic, and subclavian routes, depending on patient anatomy and vascular suitability. Commonly used valves include the Edwards SAPIEN (balloon-expandable) and Medtronic CoreValve (self-expanding) systems. The procedure is performed under fluoroscopic and echocardiographic guidance, usually under local or conscious sedation^1,10.

2. Transcatheter Mitral Valve Repair (MITRACLIP SYSTEM)

Transcatheter Mitral Valve Repair (TMVR) using the MitraClip system is a minimally invasive procedure designed to treat mitral regurgitation (MR), a condition in which the mitral valve fails to close properly, allowing blood to flow backward from the left ventricle to the left atrium. The MitraClip system works on the principle of edge-to-edge leaflet repair, where a small clip is delivered via a catheter inserted through the femoral vein, advanced into the right atrium, and then guided across the interatrial septum into the left atrium under real-time transesophageal echocardiographic (TEE) and fluoroscopic imaging. The clip grasps the anterior and posterior mitral valve leaflets, creating a double-orifice valve that reduces regurgitation and improves forward blood flow².

3. Transcatheter Tricuspid Valve Repair (TRICLIP / PASCAL SYSTEMS)

Transcatheter Tricuspid Valve Repair (TTVR) using TriClip or Pascal systems is a minimally invasive procedure designed to treat tricuspid regurgitation (TR), a condition in which the tricuspid valve fails to close properly, causing backward flow of blood from the right ventricle into the right atrium. The procedure is based on the edge-to-edge repair technique, like the MitraClip system used for mitral valves. A catheter is introduced through the femoral vein and advanced into the right atrium, where the device is positioned under real-time echocardiographic and fluoroscopic guidance. The clip grasps the tricuspid valve leaflets, bringing them together to reduce the regurgitant orifice, improve valve coaptation, and enhance forward blood flow³.

4. Balloon Valvuloplasty:

This is the most common form of valvuloplasty and is typically used for mitral or aortic valve stenosis. During the procedure, a catheter with a deflated balloon at the tip is inserted into the narrowed valve. The balloon is then inflated, stretching the valve and improving blood flow. Once the valve is sufficiently widened, the balloon is deflated and removed^1,2,3.

Advantages of Catheter-Based Valve Repair:

1. Minimally invasive procedure – Performed through small punctures (usually in the groin or chest) instead of open-heart surgery, avoiding large incisions and sternotomy.

2. No need for cardiopulmonary bypass – The heart continues to beat during the procedure, reducing risks associated with heart-lung machine use.

3. Can be done under local anaesthesia – Suitable for elderly or high-risk patients who cannot tolerate general anesthesia.

4. Reduced surgical trauma – Causes less tissue damage, less bleeding, and lower postoperative pain.

5. Shorter hospital stay – Most patients are discharged within 2–4 days, compared to 1–2 weeks after open surgery.

6. Faster recovery and rehabilitation – Patients regain normal activities within days rather than weeks.

7. Lower risk of infection and wound complications – Small entry sites minimize infection risk and postoperative complications.

8. Reduced blood loss and transfusion need – Minimally invasive access leads to minimal bleeding during the procedure.

9. Improved safety for high-risk patients – Allows treatment for patients previously considered inoperable due to age or comorbid conditions.

10. Comparable outcomes to surgery – In selected patients, procedures like TAVR and MitraClip provide similar survival and hemodynamic results as surgical repair.

11. Option for re-intervention – Useful for patients with degenerated bioprosthetic valves or failed surgical repairs, avoiding repeat open-heart surgery.

12. Enhanced imaging guidance – Performed under real-time echocardiography and fluoroscopy, ensuring accurate placement and improved outcomes.

13. Multidisciplinary approach – Enables collaboration between interventional cardiologists, cardiac surgeons, and imaging specialists in a hybrid operating room setting.

14. Early symptom relief – Rapid improvement in cardiac output, reduction of dyspnea, fatigue, and improvement in exercise tolerance.

15. Better quality of life – Due to quicker recovery, fewer complications, and improved heart function, patients report better overall well-being.

Disadvantages of Catheter-Based (Transcatheter) Valve Repair:

1. Limited durability: Catheter-based repairs may not last as long as traditional surgical valve replacements. Some devices may require repeat interventions over time.

2. Incomplete repair: In some patients, the repair may not fully correct the valve dysfunction, leading to residual regurgitation or stenosis.

3. Anatomical limitations: Not all patients are suitable candidates due to valve anatomy, calcification, or other structural heart issues.

4. Risk of vascular complications: Accessing the heart via catheters can cause bleeding, vessel injury, or hematoma at the insertion site.

5. Risk of device malfunction or migration: Rarely, the implanted device may move, detach, or fail, necessitating further intervention.

6. Potential for stroke or embolism: Small clots or debris can dislodge during the procedure, increasing the risk of stroke.

7. Limited long-term data: Especially for newer devices, there is less long-term evidence compared to conventional surgery.

8. High cost: The procedure and devices are often more expensive than surgical alternatives.

9. Specialized expertise required: Only highly trained interventional cardiologists can perform these procedures, which may limit availability.

10. Not suitable for severe or complex valve disease: Patients with multiple valve problems, severe calcification, or certain congenital defects may still need open-heart surgery.

Recent Advancements in India:

In recent years, India has made remarkable progress in catheter-based valve repair and replacement techniques. Advanced Transcatheter Aortic Valve Replacement (TAVR) systems such as Abbott’s Navitor Vision and Medtronic’s Evolut FX+ were introduced in 2025, offering greater precision, smaller catheter sizes, and easier valve positioning. Indian company Meril Life Sciences has developed indigenous devices like Myval for TAVR and MyClip, India’s first transcatheter mitral valve repair (TEER) system, making non-surgical valve therapy more affordable and accessible⁵. Major hospitals such as Apollo, Fortis, and Kauvery have successfully performed complex combined procedures—like dual valve (TAVR + MitraClip) and TAVR with leadless pacemaker implantation—showing significant advancement in multidisciplinary cardiac care. Furthermore, catheter-based valve interventions are now expanding beyond metropolitan cities to tier-2 centres like Nagpur and Jaipur, reflecting wider national adoption. Overall, these innovations highlight India’s rapid growth in minimally invasive cardiac therapies, combining indigenous technology, global device integration, and improved patient outcomes⁶.
