First beating-heart valve-sparing aortic root repair: a "corset" technique

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Aortic Diseases

Background:

• Aortic root dilatation and insufficiency pose significant clinical challenges.
• Current surgical options for aortic root remodeling can be invasive.
• Minimally invasive approaches are needed to improve patient outcomes.

Purpose of the Study:

• To evaluate the feasibility and preliminary efficacy of a novel beating-heart aortic root remodeling technique.
• To assess the impact of external vascular prosthesis placement on aortic diameter and valve function.

Main Methods:

• Two patients with aortic insufficiency and root dilatation underwent the procedure.
• A bespoke vascular prosthesis was applied externally to the aortic root and ascending aorta.
• Standard extracorporeal circulation was employed during the intervention.

Main Results:

• Postoperative CT angiography confirmed a significant reduction in aortic diameter.
• Echocardiography at 12 months showed normal aortic valve function with trivial regurgitation.
• Both patients maintained a stable aortic diameter post-procedure.

Conclusions:

• Beating-heart aortic root remodeling with an external corset is a potentially effective technique.
• This approach may offer a less invasive option for managing aortic insufficiency and dilatation.
• Further studies are warranted to validate these preliminary findings.
