The Bentall procedure is a complex cardiac surgical operation that simultaneously replaces the aortic root (the section of the aorta from which the coronary arteries arise), the ascending aorta, and the aortic valve — using a single composite graft consisting of a mechanical or biological valve within a Dacron tube graft. The coronary arteries are re-implanted (reattached) to the composite graft to maintain coronary blood flow. This procedure is the definitive treatment for disease of the aortic root — when the aorta has aneurysmal dilation at its root, combined with aortic valve pathology, requiring both to be addressed in a single elegant operation.

The most important indication for the Bentall procedure is Marfan syndrome — a genetic connective tissue disorder that causes progressive, life-threatening dilation of the aortic root and ascending aorta. The aortic root weakens and expands; if the diameter reaches 5 cm (or 4.5 cm in Marfan patients, or when growth exceeds 5 mm per year), the risk of aortic dissection or rupture — catastrophic, often fatal events — exceeds the risk of elective surgical repair. The Bentall procedure performed before dissection carries a mortality of 1–3%; untreated aortic dissection carries a mortality of 50% within 48 hours even with emergency surgery.

Other indications include: bicuspid aortic valve disease with concurrent aortic root dilation; previously dissected aortic root (Type A dissection); infective endocarditis involving the aortic root; and aortic root aneurysm of any cause (Loeys-Dietz syndrome, Ehlers-Danlos syndrome, atherosclerotic aortic disease).

India's cardiac surgery programs offer the Bentall procedure at $9,000–$15,000 — compared to $50,000–$100,000 in the United States. Experienced aortic surgeons at Apollo Hospitals, Medanta – The Medicity, Fortis, Narayana Institute, and AIIMS Delhi regularly perform this procedure with outcomes that compare favorably with international benchmarks.

What is the Bentall Procedure and Why is It Needed?

The aortic root is the short segment of the aorta immediately above the aortic valve, from which the left and right coronary arteries arise. When the aortic root dilates (aneurysm), it stretches the aortic valve annulus and causes the valve leaflets to coapt incompletely — creating aortic regurgitation (backflow of blood into the left ventricle with each heartbeat). The dilated root is also at risk of dissection — a sudden catastrophic tear in the aortic wall that can extend throughout the aorta, causing limb ischaemia, stroke, heart attack, and death.

The Bentall procedure addresses the problem comprehensively: the aneurysmal root, the diseased ascending aorta, and the regurgitant aortic valve are all replaced in a single composite graft. The coronary arteries — which arise from the dilated root — are re-implanted into buttons cut in the composite graft to maintain coronary blood supply.

The modified Bentall (or "button Bentall") technique — now standard — excises the coronary artery origins as "buttons" of aortic wall and sutures them directly to openings created in the composite graft. This technique has largely replaced the earlier inclusion (or Cabrol) technique because it eliminates the risk of pseudoaneurysm formation at the coronary anastomosis.

An alternative to the Bentall procedure for patients with intact aortic leaflets is the valve-sparing aortic root replacement (David or Yacoub procedure) — which replaces the aortic root Dacron tube while preserving the native aortic valve, avoiding the need for mechanical valve anticoagulation. This is offered at specialized centers when leaflet quality is sufficient.

Who Needs the Bentall Procedure?

The Bentall procedure is indicated for patients with aortic root aneurysm (dilation) meeting size thresholds combined with aortic valve disease requiring replacement:

Marfan syndrome: aortic root diameter above 4.5 cm (lower threshold than general population due to risk of dissection), or above 4 cm with rapid growth (over 3–5 mm/year), or family history of aortic dissection at smaller sizes.

Bicuspid aortic valve with concurrent root dilation: root diameter above 5 cm (or above 4.5 cm at the time of aortic valve surgery for other indications).

Aortic root disease from any cause (Loeys-Dietz, VEDS, atherosclerosis): root diameter above 5.5 cm in low-risk patients; above 5.0 cm in high-risk (hypertension, rapid growth, family history).

Acute Type A aortic dissection involving the root: emergency Bentall in this context carries 10–15% mortality versus near 100% untreated mortality.

Patients should be in good enough general health for major cardiac surgery. Very elderly patients or those with severe pulmonary, renal, or hepatic disease may be better served by observation (with aggressive blood pressure control) rather than elective surgery.

How is the Bentall Procedure Performed?

The Bentall procedure is performed under general anesthesia with cardiopulmonary bypass. A median sternotomy provides access to the heart and ascending aorta. The patient is cooled to moderate hypothermia (25–28°C) to protect the organs during the period of cardiac arrest. A detailed aortic root anatomy is studied pre-operatively by CT angiography and echocardiography.

After establishing bypass, the aorta is cross-clamped, the heart arrested with cardioplegia delivered into the coronary ostia. The diseased aortic root is excised — the sinus of Valsalva tissue is resected, leaving only the coronary ostia as "buttons." The aortic valve within the composite graft is sized and sutured to the aortic annulus with interrupted sutures (mechanical valve provides lifelong durability; tissue/biological valve avoids anticoagulation but may need replacement in 10–15 years).

The coronary button anastomoses are then constructed: holes are cut in the appropriate positions of the composite graft, and the coronary buttons are sutured to these openings with fine polypropylene sutures. The distal end of the composite graft is then sutured to the remaining ascending aorta or aortic arch (depending on the extent of aortic involvement). After de-airing, the cross-clamp is removed and the heart restarted.

Procedure Steps

1. Pre-operative CT aortography: precise measurement of aortic root diameter, valve annulus, coronary ostia heights, ascending aorta, and arch involvement; echocardiography for valve and LV function.
2. Anesthesia: general anesthesia; arterial line bilateral; central venous line; TEE.
3. Cardiopulmonary bypass with moderate hypothermia (25–28°C): aortic and bicaval cannulation.
4. Cardiac arrest: aortic cross-clamp applied; cardioplegia into coronary ostia (antegrade) and coronary sinus (retrograde) simultaneously.
5. Aortic root excision: diseased root tissue excised; coronary ostia mobilized as buttons with 5–7 mm of aortic wall cuff.
6. Valve annulus sutures: composite graft sized; interrupted sutures placed circumferentially around the aortic annulus.
7. Valve seating: composite graft lowered onto sutures; tied sequentially ensuring watertight seal.
8. Coronary button anastomoses: openings created in composite graft at appropriate positions; coronary buttons sutured with 5-0 prolene in continuous running suture.
9. Distal aortic anastomosis: composite graft trimmed to length; sutured end-to-end to distal ascending aorta or proximal arch.
10. De-airing and rewarming: air evacuated from graft; cross-clamp removed; heart restarted; patient rewarmed; weaned from bypass.
11. Hemostasis and closure: graft inspected for bleeding; pericardium and sternum closed; ICU transfer.

Bentall procedure packages in India include the composite graft (mechanical St. Jude, ATS, or CarboMedics valve/Dacron; or tissue valve/Dacron composite), surgery, anesthesia, CPB, ICU stay (2–3 days), ward stay (7–10 days), intraoperative TEE, and post-operative warfarin initiation (if mechanical valve). CT angiography surveillance at 1 year and every 3–5 years thereafter for monitoring remaining aorta is additional.

Recovery & Follow-up

Recovery from the Bentall procedure follows the standard open-heart recovery timeline: ICU 2–3 days; total hospital stay 10–14 days. Sternal healing requires 6–8 weeks. Return to desk work at 6–8 weeks; full physical activity at 10–12 weeks.

Patients with mechanical valves require lifelong warfarin anticoagulation (target INR 2.5–3.5). Regular INR testing (initially weekly, then monthly when stable) is essential. Patients with biological composite grafts do not need lifelong anticoagulation but the valve will degrade over 10–15 years and require reoperation. Younger patients (under 60) benefit more from mechanical valves; older patients from biological valves.

Annual echocardiography and CT aortography every 3–5 years monitor the remaining aorta (descending aorta and arch, which are not replaced during the Bentall). Marfan patients require meticulous lifelong aortic surveillance with beta-blocker therapy (reduces aortic wall stress and progression).

Recovery Tips

• For mechanical valve patients: maintain INR in target range (2.5–3.5) with weekly checks initially; carry a warfarin alert card at all times.
• Marfan patients: take beta-blockers (bisoprolol, atenolol) at target dose lifelong — reduces aortic wall stress and rate of dilation of the remaining aorta.
• Annual echocardiogram and CT aortography every 3–5 years — the remaining descending aorta can dilate over time.
• Avoid contact sports, heavy weightlifting, and isometric exercises — high-afterload activities stress the aortic wall.
• Carry an emergency letter describing your Bentall procedure, composite graft type, and INR range when travelling.
• Endocarditis prophylaxis before dental procedures — lifelong for prosthetic valve recipients.

Risks & Complications

The Bentall procedure carries a mortality of 1–3% for elective repair in experienced hands. Emergency repair for acute Type A dissection has a 10–15% mortality. Specific complications include: bleeding from coronary button anastomoses (re-exploration required in 3–5%); stroke (1–3%); complete heart block requiring pacemaker (1–2%); pseudo-aneurysm at coronary button anastomosis (late complication, 1–5% — prevented by the button Bentall technique); and the standard mechanical valve risks (thromboembolism, bleeding from anticoagulation, structural valve deterioration — the latter not an issue for mechanical valves). Biological composite graft failure requiring reoperation at 10–15 years is planned for younger patients choosing biological options.

Frequently Asked Questions

Do I need the Bentall procedure or can I have valve-sparing surgery?

If your native aortic valve leaflets are of good quality (thin, flexible, without calcification or fenestrations), a valve-sparing aortic root replacement (David or Yacoub procedure) preserves the native valve, avoiding lifelong anticoagulation. This is offered at specialized centers. If the leaflets are diseased, calcified, or bicuspid with significant fusion, a composite valve-graft (Bentall) is required.

Will I need blood thinners after the Bentall procedure?

If a mechanical valve composite graft is used, lifelong warfarin anticoagulation (INR target 2.5–3.5) is required. If a biological valve composite graft is used, aspirin only is typically needed (no warfarin). The choice between mechanical and biological composite graft depends on age, lifestyle, and ability to manage anticoagulation.

What is the success rate of the Bentall procedure?

Elective Bentall surgery has a 30-day survival rate of 97–99% at experienced centers. Long-term 10-year survival is 85–90% for Marfan patients and similar for other indications, reflecting excellent long-term durability of the composite graft.

What is the cost of the Bentall procedure in India?

The Bentall procedure costs $9,000–$15,000 in India — compared to $50,000–$100,000 in the USA. Packages include the composite graft (mechanical or biological), surgery, ICU, and post-operative care.
