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.
Types of Surgical Aortic Valve Replacement (SAVR)
Mechanical Valve Replacement: Uses durable synthetic materials like metal or carbon. Long-lasting but requires lifelong blood-thinning medications.
Bioprosthetic Valve Replacement: Made from animal tissue (porcine or bovine) or human donor valves. Does not require long-term blood thinners but may need replacement after 10–20 years.
Minimally Invasive SAVR: Performed through smaller chest incisions. Offers faster recovery, reduced pain, and minimal scarring.
Ross Procedure: Replace the diseased aortic valve with the patient’s pulmonary valve. Ideal for younger patients, the pulmonary valve is replaced with a donor valve.
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: Narrowing of the aortic valve causing chest pain, breathlessness, fatigue, or fainting. SAVR restores blood flow and improves heart function.
Severe Aortic Regurgitation: A leaky valve leads to blood flowing back into the heart. SAVR repairs or replaces the valve to maintain proper circulation.
Symptomatic Patients: SAVR is recommended for those with severe fatigue, breathlessness, chest pain, or fainting due to aortic valve disease.
Disease Progression: SAVR prevents the worsening of rapidly progressing or severe valve disease and related complications.
Failed Previous Interventions: SAVR is needed if previous treatments, like TAVR or valve repair, fail or lead to dysfunction.
Combined Procedures: SAVR can be done alongside other surgeries, like CABG, for patients with multiple heart conditions.
Preparing for Surgical Aortic Valve Replacement (SAVR) Procedure
Preparing for Surgical Aortic Valve Replacement (SAVR) involves thorough planning, medical evaluations, and lifestyle adjustments to ensure a safe and successful procedure and recovery. Here’s how to prepare:

Medications: Inform your doctor about all medicines you’re taking, including supplements and herbal remedies.
Lifestyle Changes: Maintain a healthy weight, eat a balanced diet, drink less alcohol, and smoke less.
Physical Activity: To get more fit for surgery, do some mild exercise.
Dental Care: Address any dental issues before surgery to prevent infections.
Vaccinations: Confirm that you have had the most recent shots.
Medication Adjustments: Your doctor may adjust certain medications before surgery.
Blood Donation: Consider donating blood if recommended for potential transfusions.
Preoperative Testing: Finish the required testing, which may include speaking with an anesthesiologist.
Education: Participate in seminars to ask questions and learn about the process.
Legal & Financial: Complete necessary documentation and insurance arrangements.
Support System: Arrange for help at home before and after surgery.
Home Preparation: Set up a recovery area with comfortable seating and essential supplies.
Transportation: Arrange transportation to and from the hospital.
Fasting and Guidelines: Take any medicine and fasting based on your doctor’s advice.
Emotional Readiness: Use relaxation methods to reduce anxiety before surgery.
Follow the directions: Follow all preoperative advice for a simple procedure.
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: General anesthesia ensures the patient is unconscious and pain-free.
Incision: An incision is made in the chest, typically through the sternum, to access the heart.
Heart-Lung Bypass: Blood is rerouted through a heart-lung machine to maintain circulation during surgery.
Valve Replacement: A new prosthetic valve, either mechanical or bioprosthetic, is firmly inserted after the sick valve is removed.
Closing and Recovery: The incision is sealed, the heart is closed, and circulation returns.
Monitoring: Patients get standard hospital treatment following extensive intense critical care unit monitoring throughout the early phases of recovery.
Rehabilitation: Strengthening is helped by physical therapy. The average length of stay in the hospital is one week.
Follow-up: Appointments on a regular basis guarantee appropriate valve function and recovery.
Recovery after Surgical Aortic Valve Replacement (SAVR) Procedure
Recovery after Surgical Aortic Valve Replacement (SAVR) is a gradual process involving healing, regaining strength, and returning to normal activities. The timeline and experience can vary for each individual, but here’s a general overview of what to expect during the recovery period:
Immediate Postoperative (In Hospital)
ICU Care: You’ll be monitored in the ICU for a few days. Heart function, vital signs, and overall condition will be closely observed.
Ventilator: You may need a ventilator for breathing, but the team will wean you off as you recover.
Pain Management: Pain medications will help manage discomfort after surgery.
Mobility: Early movement is encouraged to prevent complications and improve recovery.
Chest Tubes: Chest tubes may be inserted to drain fluid and remove air once your condition stabilizes.
Days to Weeks After Surgery
Hospital Room: Once stable, you’ll move to a regular hospital room.
Physical Therapy: Therapists will help you regain strength and mobility.
Incision Care: Follow instructions for proper wound care to prevent infection.
Diet: Your diet will transition from liquids to solids.
Medications: Follow the prescribed schedule for pain, infection prevention, and heart support.
