Modified Manouguian technique for aortic root enlargement: A case series

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Aortic Valve Surgery

Background:

• Manouguian aortic root enlargement (ARE) is a standard procedure for patients with small aortic annular sizes.
• A modified Manouguian ARE technique is presented as an alternative approach.
• Previous evaluations of this modified technique are limited to case reports.

Purpose of the Study:

• To evaluate the efficacy and safety of a modified Manouguian aortic root enlargement (ARE) procedure.
• To assess the ability to achieve satisfactory valve sizing after aortic valve replacement using this modified technique.

Main Methods:

• Retrospective case series of 13 patients undergoing modified Manouguian ARE for surgical aortic valve replacement.
• Data collected from 2015-2021 at a single institution by a single surgeon.
• Primary outcome measured was the difference in aortic valve size achieved post-procedure.

Main Results:

• Aortic stenosis was the primary indication for surgery in 92% of patients.
• Mechanical valves were implanted in 77% of patients.
• All 13 patients (100%) were successfully upsized to a satisfactory valve size.

Conclusions:

• The modified Manouguian aortic enlargement technique is safe and effective.
• This modified ARE procedure can be utilized in a diverse patient population.
• The technique facilitates successful aortic valve upsizing.
