What is Surgical Aortic Valve Replacement (SAVR)?
Surgical Aortic Valve Replacement (SAVR) is a well-established and effective medical procedure designed to treat aortic valve disease, affecting the heart's ability to pump blood efficiently. The aortic valve, a crucial component of the heart, regulates the flow of oxygen-rich blood from the heart to the rest of the body. When this valve becomes diseased or narrowed (aortic stenosis), it can lead to chest pain, shortness of breath, and fatigue.
Indications of Surgical Aortic Valve Replacement (SAVR) Procedure:
Surgical Aortic Valve Replacement (SAVR) is a procedure primarily indicated for individuals with severe aortic valve disease, specifically aortic stenosis or aortic regurgitation, where the aortic valve becomes narrowed or leaky. The decision to undergo SAVR is based on a thorough cardiac surgeon and medical team evaluation. Indications for SAVR include:
- Severe Aortic Stenosis : When the aortic valve becomes significantly narrowed, restricting blood flow from the heart into the aorta and the rest of the body, it can lead to symptoms like chest pain, shortness of breath, fatigue, and fainting. SAVR is often recommended to alleviate these symptoms and improve overall heart function.
- Severe Aortic Regurgitation : Aortic regurgitation occurs when the aortic valve does not close properly, allowing blood to leak back into the heart. This can lead to an enlarged heart and reduced pumping efficiency. SAVR may be considered to repair or replace the valve and restore proper blood flow.
- Symptomatic Patients : SAVR is often recommended for patients who experience significant symptoms, such as severe fatigue, breathlessness, chest pain, or fainting, due to aortic valve disease.
- Reduced Heart Function : If aortic valve disease has significantly decreased heart function, SAVR may be recommended to improve cardiac output and overall cardiovascular health.
- Disease Progression : When aortic valve disease progresses rapidly or becomes increasingly severe, surgical intervention may be necessary to prevent further deterioration and complications.
- Failed Previous Interventions : Patients who have previously undergone other procedures, such as aortic valve repair or less invasive interventions like Transcatheter Aortic Valve Replacement (TAVR), and have experienced treatment failure or valve dysfunction may be candidates for SAVR.
- Combined Procedures : SAVR may be considered in combination with other heart procedures, such as coronary artery bypass grafting (CABG), for patients with multiple cardiac issues.
Steps involved in Surgical Aortic Valve Replacement (SAVR) Procedure:
Surgical Aortic Valve Replacement (SAVR) is a complex procedure performed by a team of skilled cardiac surgeons, anesthesiologists, and other medical professionals. It involves several key steps to replace a diseased or malfunctioning aortic valve with a prosthetic valve. Here's an overview of what happens during a SAVR procedure:
- Anesthesia : The patient is put under general anaesthesia to ensure they are unconscious and pain-free during the surgery.
- Incision : A surgical incision is made in the chest, typically through the sternum (breastbone). This grants access to the heart and aorta.
- Cardiopulmonary Bypass (Heart-Lung Bypass) : The patient's blood circulation is rerouted from the heart and lungs to a heart-lung machine. This machine takes over the function of pumping blood and oxygenating it, allowing the surgeon to work on the heart while it's not actively pumping.
- Cooling the Body : In some cases, the patient's body temperature is lowered to reduce the body's oxygen demand and protect the organs during the temporary suspension of blood circulation.
- Opening the Heart : The surgeon carefully opens the heart's chambers to access the aortic valve.
- Removal of the Diseased Valve : The damaged or diseased aortic valve is removed from its position.
- Sizing and Placement : The surgeon measures the size of the patient's annulus (the base of the aorta where the valve sits) to determine the appropriate size of the prosthetic valve.
- Suturing the New Valve : The prosthetic valve (typically made of bioprosthetic or mechanical materials) is securely sewn into the annulus, replacing the original valve's function.
- Closing the Heart : Once the new valve is in place and functioning correctly, the heart's chambers are closed, and the seat can resume pumping.
- Separation from the Heart-Lung Bypass Machine : The patient's blood circulation is gradually returned to the heart, and the heart-lung machine is disconnected.
- Closing the Incision : The surgical incision is closed with sutures or staples. The sternum may be wired together to promote proper healing.
- Recovery and Monitoring : The patient is transferred to the intensive care unit (ICU) for close monitoring during the initial stages of recovery. Vital signs, heart function, and other parameters are closely observed.
- Postoperative Care : Once stable, the patient is moved to a regular hospital room for further recovery. Pain management, wound care, and rehabilitation begin.
- Rehabilitation and Discharge : Physical therapy and rehabilitation help the patient regain strength and mobility. The length of the hospital stay varies, but it typically lasts around a week.
- Follow-up : After discharge, the patient will have regular follow-up appointments with their medical team to monitor their progress, assess the functioning of the new valve, and ensure proper recovery.
