What is aortic annulus enlargement?

Posterior enlargement of the aortic root and annulus can be achieved by extending the aortotomy through the noncoronary sinus across the aortic annulus (Nicks) or alternatively the incision can be extended posteriorly though the commissure at the left and noncoronary sinus onto the anterior mitral valve leaflet ( …

How long does it take to recover from Bentall aortic replacement?

Full recovery usually takes about 2 months. Most patients are able to drive in about 3 to 8 weeks after surgery.

What is aortic root enlargement?

Otherwise known as an aortic root aneurysm, a dilated aortic root is when the first section of the aorta, where the aortic valve resides, becomes enlarged. When this enlargement reaches a critical size, there is a risk of it rupturing or tearing, leading to a life-threatening situation.

What is annular enlargement?

Aortic annulus enlargement is an additional surgical procedure and it is performed in an anatomical area with high risk of bleeding. These facts have provoked the debate about the impact of this procedure on the early results of aortic valve surgery.

What causes aortic root dilation?

The primary cause of noninflammatory aortic root dilation is Marfan disease; the major causes of inflammatory aortic root dilation include giant cell aortitis, Takayasu’s disease, and syphilis. In these conditions, the inflammatory process generally does not affect the valve itself.

How long are you in hospital after aortic valve replacement?

After an aortic valve replacement, you’ll usually need to stay in hospital for about a week. The time it takes to fully recover varies depending on factors like your age and overall health. Your breastbone will usually heal in about 6 to 8 weeks, but it may be 2 to 3 months before you feel your normal self again.

Can an enlarged aortic root shrink?

Over time, the aneurysm shrinks. In some patients, when stents are not possible, open surgery (requiring an incision in your chest) may be necessary to repair the aneurysm by placing an artificial blood vessel into the aorta to replace the aneurysm.

How is modified manouguian technique used for aortic root enlargement?

A modified Manouguian technique was performed without entering into the left atrium or incising the anterior leaflet of the mitral valve (2). The enlargement was achieved by extending the aortotomy into the fibrous tissue between the non-coronary cusp and the left coronary cusp and onto the subaortic curtain.

How is a modified manouguian technique performed in the left atrium?

A dissection of the left atrium roof was made in order to make a clear incision. A modified Manouguian technique was performed without entering into the left atrium or incising the anterior leaflet of the mitral valve (2).

When was posterior aortic root enlargement first performed?

Posterior aortic root enlargement can be performed to allow for implantation of a larger size valve. Nicks and colleagues first proposed posterior root enlargement in 1970.

What kind of sutures are used for aortic root enlargement?

Pledgeted 2.0 polyester sutures (TiCron®, Covidien, Dublin, Ireland) were placed circumferentially around the aortic annulus (placing them from the outside into the patch zone). The sutures were placed in the prosthetic valve and then tied into place.
