It's Topic Tuesday!

Good morning, Aortic Hope community! Today we're talking about a common surgical procedure for aortic root aneurysms: the Bentall procedure.


What Is an Aortic Root Aneurysm?


The aortic root is the very first section of the aorta, right where it connects to the heart. It includes the aortic valve and the origins of the coronary arteries (which supply blood to the heart muscle itself). When this area becomes enlarged or weakened, it's called an aortic root aneurysm. This is particularly common in people with:


  • Bicuspid aortic valve

  • Marfan syndrome

  • Loeys-Dietz syndrome

  • Other connective tissue disorders

  • Family history of aortic aneurysms



Because the aortic root involves both the valve and the origins of the coronary arteries, surgery in this area requires special techniques.


What Is the Bentall Procedure?


The Bentall procedure, first described in 1968, is a surgery that replaces both the aortic root and the aortic valve as a single unit. A tube graft with a valve sewn inside it replaces the dilated section, and the coronary arteries are reattached to the new graft.


This procedure is named after Hugh Bentall, the British surgeon who pioneered the technique. Although there are number of options to repair this portion of the aorta, the Bentall procedure is often recommended when:


  • The aortic root is significantly enlarged

  • The aortic valve is also diseased (stenosis or regurgitation)

  • The valve cannot be repaired and saved




But wait, the Bentall comes with options!


One of the most important decisions you'll discuss with your surgeon is the type of valve used in your Bentall procedure. There are two main options:


  1. Mechanical Valves


Mechanical valves are made of durable synthetic materials (usually carbon and titanium).

Benefits:


  • Very durable (can last a lifetime)

  • Lower chance of needing another operation

  • Good option for younger patients


However, there are additional aspects to consider:


  • Requires lifelong blood thinner medication (warfarin/Coumadin)

  • Regular blood tests (INR monitoring) to ensure proper anticoagulation

  • Small ongoing risk of bleeding or clotting complications



  1. Tissue (Bioprosthetic Valve)


Tissue valves are made from animal tissue (usually pig or cow) that has been specially treated.

Benefits:


  • Usually no need for lifelong blood thinners (after initial recovery)

  • More flexible lifestyle without regular INR monitoring




There are considerations with tissue valves as well:


  • Limited durability: typically lasts 10-20 years maximum

  • Because of the shorter time frame there is a higher chance of needing a reoperation later in life




How Do You Choose?


There is no single right answer because the best choice depends on your individual situation. Luckily this is a decision that you and your surgeon will make as a team, but factors that you should take into account include:


Age: Younger patients may benefit from mechanical valves to avoid reoperation while older patients may prefer tissue valves

Lifestyle factors: Active lifestyle, occupation, or travel considerations

Ability to take blood thinners

Feelings about the possibility of reoperation vs. lifelong medication


The Bottom Line


The Bentall procedure is a well established, effective surgery for aortic root aneurysms. Both mechanical and tissue valves have important benefits and considerations. The best choice is a shared decision between you and your surgical team!


Have a great week, and Think Aorta!
