Aortic Valve Replacement India

Types of Aortic Valve Replacement India

There are two main types of aortic valve replacement which can be further divided into their sub types. These are:

Traditional/Open-Heart Aortic Valve Replacement

• Median sternotomy
• Mini sternotomy
• Partial sternotomy
• Manubrium sparing sternotomy

Minimally Invasive Aortic Valve Replacement

• TAVR/TAVI
• Robot assisted aortic valve replacement

Traditional/Open-Heart Aortic Valve Replacement

In this traditional procedure, a long incision of 6-8 inches is made. It provides better vision to the surgeon during the procedure. This include:

Median Sternotomy: The most common approach, where a central chest incision is made, allowing access to the heart. The surgery is performed with the heart temporarily stopped using a heart-lung bypass machine.

Mini-Sternotomy:   A smaller incision is made in the upper part of the breastbone that provides a less invasive option. It also utilizes a heart-lung bypass machine.

Partial Sternotomy: Involves a smaller incision on the side of the chest, with partial division of the sternum to reach the heart for valve replacement.

Manubrium-Sparing Sternotomy: A newer technique where a smaller incision is made between the collarbones, preserving the upper part of the sternum. This approach helps to reduce postoperative pain and facilitate faster recovery.

Minimally Invasive Aortic Valve Replacement

Unlike the traditional approach, it made a shorter incision of 4-5 inches and usually needs less recovery time after the procedure. These are:

Transcatheter Aortic Valve Replacement (TAVR/TAVI): A minimally invasive procedure that avoids open-heart surgery. It involves inserting a catheter through a small incision, usually in the groin or chest, to guide a replacement valve into the heart. The folded valve is then expanded to replace the diseased valve. TAVR is generally recommended for higher-risk patients or those who are not suitable for open-heart surgery.

Robotic-Assisted Aortic Valve Replacement: This approach involves a robotic surgical system to assist the surgeon. Small incisions are made, and the surgeon controls robotic arms to perform the valve replacement with improved precision and dexterity.

Procedure of Aortic Valve Replacement

Here is the general overview of aortic valve replacement procedure:

Anesthesia: The patient is administered general anesthesia to ensure they are unconscious and pain free throughout the surgery.

Incision: A surgical incision is made, depending on the chosen approach. This could be a median sternotomy, a mini-sternotomy, a partial sternotomy, or a smaller incision for minimally invasive techniques.

Placing the Patient on Bypass: To perform the surgery safely, the patient is connected to a heart-lung bypass machine. This machine temporarily takes over the function of the heart and lungs, allowing the surgeon to stop the heart and work on the aortic valve.

Removing the Diseased Valve: The surgeon carefully removes the malfunctioning or diseased aortic valve. This may involve cutting and excising the valve leaflets and clearing any calcified or obstructive tissue.

Valve Replacement: The new valve is then placed in the aortic valve position. The choice of valve type depends on various factors. The valve is securely stitched or sutured into place to ensure proper functioning.

Checking Valve Function: The surgeon verifies the correct positioning and functionality of the new valve. They may use various techniques, such as injecting dye to assess blood flow or testing the valve's opening and closing mechanism.

Closing the Incision: Once the valve replacement is confirmed, the surgeon closes the incision by using sutures. In some cases, temporary chest tubes may be inserted to drain any fluid or air that may accumulate after the closure of incision.

Cost of Aortic Valve Replacement in India

The cost of aortic valve replacement in India comes in the range of 6570 USD to 8030 USD. However, it can vary according to the type of procedure chosen by the surgeon and facilities provided by the hospital. The cost can also vary from hospital to hospital and city to city in India.

Symptoms and Risk factors

Here are some of the conditions in which the aortic valve replacement is usually recommended. These are:

• Severe Aortic Stenosis
• Symptomatic Aortic Regurgitation
• Bicuspid Aortic Valve with Significant Dysfunction
• Aortic Valve Disease with Left Ventricular Dysfunction
• Aortic Valve Disease in Aortic Aneurysm or Dissection
• Aortic Valve Disease in Connective Tissue Disorders 
• Aortic Valve Disease in Endocarditis
• Prosthetic Valve Dysfunction
• Aortic Valve Disease with Severe Symptoms (e.g., chest pain, shortness of breath) which is unresponsive to other medical treatments.

Risk Factors of Aortic Valve Replacement

Some of the risk factors associated with aortic valve replacement are:
Surgical complications:

In any open surgery, there is always the risk of developing infection, excess bleeding and pneumonia. These risks should be controlled by using specific medications.

Arrhythmias

Arrhythmias are the irregular heart rhythms that can develop after aortic valve replacement. In most cases, they resolve on their own, but in some cases the proper medications or further treatment is required.

Valve Dysfunction

Sometimes the new valve may not function properly and cause issues such as leakage or insufficient blood supply to the body due to narrowing of valves. In this case, additional surgery will be required.

Blood Clots

Blood clots can form around the new valve or in other areas that can lead to complications like brain hemorrhage or heart attack. Medications for thinning blood should be used after surgery.

Limited Lifespan of Valve

Some valves have a limited lifespan and can be damaged over time. This may require new surgery for valve replacement in future
