What Is a Bentall Procedure and Who Needs It?

A Bentall procedure is a major open-heart operation that reconstructs the aortic valve, root, and ascending aorta together, using a single composite graft in place of the diseased segment.
Surgeons turn to it for serious, potentially life-threatening aortic conditions such as an enlarging aneurysm, an aortic dissection, or significant valve regurgitation.
Many of these cases trace back to an underlying genetic connective tissue disorder, Marfan syndrome being the most recognised example.
The need for surgery gets confirmed through imaging and clinical assessment, not through symptoms alone.

According to Dr. Vishal Khullar, a leading Cardiac Surgeon in Mumbai, “The root and the valve don’t always fail on their own timeline. When both are compromised, patching one and leaving the other is a short term fix. A Bentall procedure treats them in the same sitting.”

Not every root aneurysm calls for this exact operation. These are the situations where it becomes the right call.

Marfan Syndrome: Connective tissue disease weakens the aortic wall early and unevenly. Root replacement before rupture or dissection is standard care in this group.

Bicuspid Valve With Root Dilation: A two leaflet valve often comes paired with a wider than normal root. When both cross treatment thresholds at the same time, Bentall handles both in one operation.

Type A Dissection: An emergency tear running through the root and ascending aorta. Once this diagnosis is confirmed, delay isn’t really an option.

Failed Prior Repair: Some patients return after a valve sparing procedure, or a redo case where the native valve can no longer be preserved. A composite graft becomes the fallback.

Every case prices differently once the anatomy is confirmed, so it’s worth understanding the range beforehand. That breakdown of aortic root cost is covered separately. 

Dr. Vishal Khullar has spent over thirty years operating on the aortic root, valve, and arch. Training at Cleveland Clinic, followed by a stint as Senior Associate Consultant at Mayo Clinic, shaped how he approaches complex root surgery. Every Bentall case gets planned around the patient’s own anatomy, not a fixed template. His team runs a full review before any composite graft case reaches the operating table. That mix of experience and planning matters most when the root, valve, and coronary arteries are all being rebuilt together.

Coronary reimplantation is the step most likely to go wrong in less experienced hands, and it’s where his training really shows. Patients get a clear, honest choice between mechanical and biological grafts, weighed against their own age and lifestyle. Redo and emergency Bentall cases sit within his regular operative scope, not just planned elective ones.
