Aortic Root Replacement With Autologous Pericardium Valved Conduit.

Area of Science:

• Cardiac Surgery
• Biomaterials in Medicine
• Aortic Valve Repair and Replacement

Background:

• Current aortic prosthesis options face challenges in minimizing perioperative morbidity, pressure gradients, and ensuring long-term durability.
• Trileaflet aortic valve reconstruction with autologous pericardium shows promise as an alternative, offering good postoperative gradients and avoiding anticoagulation.

Purpose of the Study:

• To introduce a novel adaptation of the modified Bentall procedure.
• To utilize a self-fabricated valved conduit with trileaflet aortic valve neocuspidization using autologous pericardium.

Main Methods:

• Adaptation of the modified Bentall procedure.
• Creation of a self-fabricated valved conduit.
• Trileaflet aortic valve neocuspidization using autologous pericardium.

Main Results:

• The novel technique aims to achieve excellent postoperative gradients and large effective orifice areas.
• This method avoids the need for long-term anticoagulation, a significant advantage over traditional prostheses.

Conclusions:

• The described self-fabricated pericardial valved conduit represents a promising alternative for aortic root replacement.
• This innovative approach may overcome limitations of current aortic valve replacement strategies, enhancing patient outcomes and durability.
