Aortic Valve Replacement (Minimally Invasive)

Minimally invasive aortic valve replacement (AVR) surgery is a surgical procedure performed to replace a diseased or malfunctioning aortic valve using smaller incisions and specialized surgical techniques. This approach aims to reduce trauma, shorten recovery time, and minimize complications compared to traditional open-heart surgery.

 

Treatments

Minimally invasive aortic valve replacement is the primary treatment for individuals with aortic valve stenosis or regurgitation, where the valve is narrowed or leaky. It is typically recommended when surgical intervention is necessary, and the patient is deemed suitable for a less invasive approach.

 

Before the Procedure

Before undergoing minimally invasive aortic valve replacement, a thorough evaluation is conducted to assess the patient’s overall health and determine the appropriateness of the procedure. This evaluation may include medical history review, physical examinations, blood tests, imaging tests (e.g., echocardiogram, CT scan), and a comprehensive cardiac assessment. The patient’s surgical risk is assessed, and preoperative preparations, such as medication adjustments and lifestyle modifications, may be recommended.

 

During the Procedure

The specific technique used during minimally invasive aortic valve replacement may vary depending on the surgeon’s preference and the patient’s individual characteristics. However, the general steps involved in the procedure include:

• Anesthesia: The patient is placed under general anesthesia to ensure they are unconscious and pain-free throughout the procedure.
• Incisions: Several small incisions, typically ranging from two to four inches, are made in the chest. Alternatively, robotic-assisted techniques may involve even smaller incisions.
• Valve Replacement: The surgeon accesses the heart through the incisions and replaces the diseased aortic valve with a prosthetic valve. The valve may be mechanical or biological (tissue) depending on various factors, including the patient’s age, overall health, and preferences.
• Closure: After the new valve is securely in place, the incisions are closed using sutures or adhesive materials.

 

 

After the Procedure

After minimally invasive aortic valve replacement, the patient is transferred to the recovery area and closely monitored. The vital signs, heart function, and oxygenation are continuously assessed. Pain management, medication administration, and fluid balance are carefully monitored and adjusted as needed. The patient may require temporary ventilation support and is gradually weaned off the ventilator.

 

Advantages

• Smaller Incisions: Minimally invasive techniques result in smaller incisions, reducing surgical trauma and scarring.
• Reduced Blood Loss: The specialized surgical techniques used during minimally invasive surgery can minimize blood loss.
• Faster Recovery: Compared to traditional open-heart surgery, minimally invasive AVR generally leads to a faster recovery time, allowing patients to return to normal activities sooner.
• Shorter Hospital Stay: The length of hospitalization is typically shorter for patients undergoing minimally invasive AVR compared to open-heart surgery.

 

Risks and Complications

While minimally invasive aortic valve replacement is generally considered safe, it carries certain risks and complications, which may include:

• Bleeding: There is a risk of bleeding during or after the procedure, which may require blood transfusions or further intervention.
• Infection: Infection at the incision sites or in the chest cavity is a potential complication, which may require antibiotics or additional treatments.
• Valve-related Issues: Complications related to the artificial valve, such as valve malfunction, infection, or blood clot formation, can occur.
• Damage to Surrounding Structures: There is a small risk of injury to nearby structures, such as blood vessels, heart tissue, or nerves.

 

Typical Recovery Time

The recovery time after minimally invasive aortic valve replacement can vary depending on individual factors, including the patient’s overall health, age, and the specific technique used. However, in general, patients can expect a shorter hospital stay compared to open-heart surgery, typically ranging from a few days to a week. The complete recovery period may take several weeks to a few months, during which the patient gradually resumes normal activities under the guidance of the healthcare team.

 

 

Results and Post-Procedure Care

Minimally invasive aortic valve replacement has shown excellent outcomes in terms of symptom relief, improved heart function, and long-term survival rates. Following the procedure, post-procedure care may include:

• Regular follow-up appointments with the healthcare team to monitor the artificial valve’s function, overall cardiac health, and recovery progress.
• Medication adherence, including anticoagulants or antiplatelet drugs if prescribed.
• Cardiac rehabilitation programs to gradually increase physical activity and improve cardiovascular fitness.
• Close monitoring for any signs of infection, abnormal symptoms, or complications and seeking immediate medical attention if any concerns arise.
