Overview
The Bentall procedure is a specialised open-heart surgery used to treat conditions affecting the aortic root and ascending aorta, particularly when the aortic valve is also diseased or needs to be replaced. The procedure involves replacing the affected section of the aorta and the aortic valve with a composite graft.
A Bentall procedure may be recommended for conditions such as an aortic root aneurysm, certain cases of ascending aortic aneurysm, aortic valve disease associated with aortic root enlargement, and selected cases of aortic dissection.
During the procedure, the diseased aortic root and valve are replaced, and the coronary arteries are reattached to the new graft. The exact surgical approach depends on the patient's condition, anatomy and overall cardiac health.
What Is the Bentall Procedure Used to Treat?
The Bentall procedure is primarily used when disease affects the aortic root and ascending aorta, particularly when replacement of the aortic valve is also required. It may be considered for conditions such as an aortic root aneurysm, an ascending aortic aneurysm involving the aortic root, aortic root enlargement with significant aortic valve disease, certain forms of aortic dissection, aortic root disease associated with connective tissue disorders, combined aortic root and valve disease, or selected cases where both the aortic root and aortic valve require replacement.
The decision to perform a Bentall procedure depends on factors such as the size and characteristics of the aneurysm, valve function, symptoms, risk of complications and the patient's overall health.
Does the Bentall Procedure Replace Both the Aortic Valve and Aorta?
Yes. A conventional Bentall procedure generally involves replacement of the aortic root and the affected ascending aorta along with the aortic valve.
A composite graft containing an artificial valve is used to replace the diseased section. The coronary arteries, which normally originate from the aortic root, are then reattached to the graft so that blood can continue to reach the heart muscle.
This makes the Bentall procedure different from an isolated aortic valve replacement, which replaces the valve without replacing the aortic root.
How Is the Coronary Artery Reattached During a Bentall Procedure?
The coronary arteries originate from the aortic root and need to remain connected to the new graft after the diseased aortic root is removed.
During a Bentall procedure, the surgeon carefully creates openings in the composite graft and reattaches the coronary artery openings to the graft. This allows blood to continue flowing from the new aortic root into the coronary arteries.
The reattachment is an important part of the procedure and requires careful surgical planning and technique.
Bentall Procedure for Aortic Dissection
Aortic dissection occurs when a tear develops in the wall of the aorta, allowing blood to enter between the layers of the arterial wall.
When a dissection involves the aortic root and is associated with significant damage to the aortic valve or ascending aorta, a Bentall procedure may be considered.
In such situations, surgery may involve replacing the affected aortic root and ascending aorta along with the aortic valve and reattaching the coronary arteries to the new graft.
The exact surgical approach depends on the location and extent of the dissection and the patient's clinical condition.
Composite Graft Aortic Root Replacement
The Bentall procedure uses a composite graft, which combines an artificial section of the aorta with a replacement valve.
The graft replaces the diseased aortic root and affected portion of the ascending aorta, while the integrated valve replaces the damaged aortic valve.
The type of valve used within the graft may vary depending on the patient's individual circumstances.
Diagnosis and Evaluation Before Bentall Surgery
A detailed cardiac and aortic assessment is required before planning a Bentall procedure. Investigations may include:
- Echocardiography
- CT angiography of the aorta
- Magnetic Resonance Imaging (MRI), when appropriate
- Electrocardiogram (ECG)
- Coronary angiography or cardiac catheterization when indicated
- Blood tests
- Assessment of heart and valve function
- Evaluation of the size and extent of the aortic aneurysm
Technology and Infrastructure
Bentall surgery requires advanced cardiac surgical facilities, detailed imaging and close monitoring throughout the treatment process. Depending on the patient's condition, care may involve advanced echocardiography, CT angiography for detailed aortic assessment, cardiac catheterisation and coronary angiography.
When required, intraoperative cardiac monitoring, cardiopulmonary bypass during surgery, intensive care monitoring after surgery, and post-operative imaging are used to assess the heart and aortic graft. The specific investigations and monitoring methods depend on the patient's condition and the surgical plan.
Bentall Procedure Recovery
Recovery after Bentall surgery varies between patients because it is a major cardiac operation. After surgery, the patient is initially monitored in a cardiac intensive care setting before moving to a hospital ward once clinically stable.
Recovery may include monitoring of heart rhythm and vital signs, pain management, respiratory care, gradual increase in physical activity, cardiac rehabilitation when recommended, wound care, medication management and regular follow-up with the cardiac team. Complete recovery can take several weeks to months, depending on the patient's overall health, age, surgical course and recovery progress.
