The Bentall procedure is a major cardiovascular operation designed to treat disease of the aortic root and ascending aorta, often in combination with replacement of the aortic valve. Named after the Italian surgeon Antonio Bentall who, with colleagues, refined the technique in the mid-20th century, this operation remains a cornerstone for patients with a dilated aortic root or aneurysmal disease that threatens heart function. The Bentall procedure is sometimes referred to as the Bentall–De Bono procedure, acknowledging the early contributions of De Bono to its development. This guide explains what the Bentall procedure involves, why it is performed, what to expect before, during, and after surgery, and how patients can plan for long-term wellbeing.
What is the Bentall procedure and why is it needed?
The Bentall procedure is a specialised operation that replaces the aortic root and ascending aorta with a synthetic graft, while simultaneously removing the diseased aortic valve and inserting a new valve into the graft. In simple terms, surgeons create a new tunnel from the heart to the body that includes both the valve and the section of the aorta that has become enlarged or weakened. The coronary arteries, which supply blood to the heart muscle, are reimplanted into the graft. This approach addresses two problems at once: structural weakness of the aorta and faulty valve function.
Indications for the Bentall procedure commonly include aortic root aneurysm, aortic dissection involving the root, or severe aortic valve disease with root dilation. Patients with connective tissue disorders, such as Marfan syndrome or Loeys–Dietz syndrome, may require this operation at a younger age due to progressive aortic dilation. In some cases, a patient may present with an enlarged aorta alongside a failing or diseased valve, which makes the Bentall procedure particularly suitable because it treats both issues in a single operation.
The Bentall procedure: core components and variations
At its heart, the Bentall procedure uses a composite graft: a prosthetic valve mounted inside a Dacron graft. The aortic root is excised, and the graft is sutured in place to form a new aorta. The prosthetic valve inside the graft can be mechanical (long-lasting but requires lifelong anticoagulation) or bioprosthetic (tissue-based, but with finite durability and usually less need for anticoagulation). The final step involves reattaching the coronary arteries to openings in the graft, a technique known as coronary ostial reimplantation or the “button” method.
There are several commonly used variations of the Bentall procedure. The classic Bentall–De Bono procedure is the foundational approach. In the Button Bentall technique, surgeons detach “buttons” of coronary tissue with a small cuff of aortic wall for reattachment to the graft. Some centres perform a modified Bentall to accommodate patient anatomy, tissue quality, or the specific valve type chosen. For patients with only aortic root dilation but preserved aortic valve function, valve-sparing root replacement may be considered as an alternative to avoid placing a prosthetic valve.
A closer look at the procedure: how the surgery is performed
Preoperative planning and preparation
Before surgery, patients undergo comprehensive imaging with echocardiography and CT or MRI angiography to map the aorta and valve anatomy. The degree of root dilation, the condition of the valve, and the involvement of the coronary arteries guide the surgical plan. A multidisciplinary team reviews the patient’s overall health, medications, and potential risks. Preoperative discussions outline the expected hospital stay, recovery timeline, and follow-up imaging needs.
In the operating room: the main steps
During the operation, the patient is placed under general anaesthesia. After opening the chest through a sternotomy, the heart is repeatedly stopped and the patient is placed on cardiopulmonary bypass to maintain blood flow while the heart is temporarily still. The diseased aortic root and ascending aorta are removed. The surgeon then attaches a composite graft, which houses the valve, to the left ventricle and the remaining aorta. The coronary arteries are reimplanted into the graft to restore normal blood flow to the heart muscle. Finally, the graft is connected to the remaining arterial tree, and the heart is restarted. Depending on the valve choice, the patient may require lifelong anticoagulation or a standard post-operative plan if a bioprosthetic valve is used.
As with any major heart operation, the Bentall procedure is performed in carefully controlled conditions with meticulous attention to sterile technique, graft sizing, and coronary attachment. The exact sequence and techniques can vary between surgeons and centres, but the fundamental goals remain the same: a durable aortic root replacement, reliable coronary blood supply, and restoration of normal valve function.
Recovery in hospital and initial post-operative care
After surgery, most patients spend several days in the intensive care unit (ICU). Recovery steps include careful monitoring of heart rhythm, blood pressure, kidney function, and signs of bleeding or infection. Pain control, respiratory therapy, and gradual reintroduction of movement are important parts of early recovery. When stable, patients transition to a standard ward before discharge. The average hospital stay after a Bentall procedure typically ranges from a week to ten days, depending on individual recovery and any complications.
What happens after a Bentall procedure: long-term care and monitoring
Long-term follow-up is essential for patients who have undergone a Bentall procedure. Regular check-ups with a cardiologist, echocardiograms to assess prosthetic valve function, and imaging to monitor the graft are standard components of ongoing care. The type of valve graft used significantly influences follow-up requirements. Mechanical valves generally necessitate lifelong anticoagulation with medications such as warfarin, requiring routine blood tests to ensure the right level of blood thinning. Bioprosthetic valves may reduce or eliminate the need for anticoagulation, but they wear out over time and might require future interventions.
Living with the Bentall procedure: lifestyle, activity, and activity restrictions
Patients can typically resume many normal activities after a full recovery, though lifestyle adjustments may be advised in the initial months. Regular physical activity is encouraged, but strenuous lifting, contact sports, or heavy exertion may be restricted for a period to protect the sternum and the new graft. Maintaining good dental hygiene and regular medical reviews helps reduce infection risk, especially for those with prosthetic heart valves. If a mechanical valve is in place, adherence to anticoagulation therapy is critical, with routine blood tests and clinic visits to monitor drug levels and prevent complications such as bleeding or thrombosis.
Risks and potential complications of the Bentall procedure
As with any major heart surgery, the Bentall procedure carries risks. Short-term risks include bleeding, infection, adverse reactions to anaesthesia, and complications related to cardiopulmonary bypass. In the longer term, potential issues include valve dysfunction or leakage (paravalvular leak), prosthetic valve thrombosis in the case of mechanical valves, stroke, or heart block requiring a pacemaker. There is also a small risk of coronary artery problems at the reimplantation sites, which can present as chest pain or recurrent symptoms of angina. Your surgical team will discuss these risks in detail during preoperative consultations, tailored to your specific anatomy and overall health profile.
Outcomes and prognosis after the Bentall procedure
Outcomes after a Bentall procedure have improved markedly over the decades due to advances in surgical technique, graft materials, and postoperative care. Many patients experience significant relief from symptoms related to aortic root disease, such as shortness of breath and chest discomfort. Survival rates have improved, with many patients living for decades after surgery, particularly when the root is repaired before major complications arise. Image-guided follow-up throughout life helps ensure that the graft and valve function remain stable, enabling people to maintain a high quality of life after this complex operation.
Alternatives to the Bentall procedure for aortic root disease
In some cases, clinicians consider alternative operations depending on the patient’s anatomy and the condition of the valve. Valve-sparing root replacement is an option when the aortic root is dilated but the aortic valve leaflets are healthy. This approach avoids placing a prosthetic valve, potentially negating the need for long-term anticoagulation. For those with extensive root and valve pathology, the Bentall procedure remains the most reliable solution. In select circumstances, staged approaches or endovascular techniques may be discussed, though these are less established for root replacement compared with the Bentall procedure.
Preparing for life after the Bentall procedure: practical considerations
Preparation for life after the Bentall procedure involves planning for ongoing medical care and lifestyle changes. Patients should arrange follow-up appointments with their cardiologist, ensure access to imaging services, and discuss the implications of their valve type on activities such as contact sports and driving. If an anticoagulant is required, individuals must learn dose management, dietary considerations, and interactions with other medications. A tailored plan for rehabilitation, nutrition, and mental well-being supports a smooth transition from hospital to home and long-term health maintenance.
Frequently asked questions about the Bentall procedure
How long does recovery take? Recovery varies, but most people need several weeks to regain energy and physical function. Returning to full work or demanding activities may take several months, depending on individual healing and the presence of any complications.
Will I need lifelong anticoagulation? If a mechanical valve is used, long-term anticoagulation is typically necessary. If a bioprosthetic valve is chosen, anticoagulation may be shorter or not required, but this depends on the surgeon’s plan and patient factors.
Can I drive after a Bentall procedure? Driving is usually allowed after a period of recovery and with clearance from the medical team. Specific guidance depends on your blood pressure, heart rhythm stability, and overall recovery.
What is the chance of needing another operation? The need for future surgery depends on valve type, ageing processes, and any associated conditions. Valve deterioration is more common with bioprosthetic valves, while mechanical valves tend to last longer but require anticoagulation management.
