Homograft-autograft valve holder.

Area of Science:

• Cardiovascular Surgery
• Biomedical Engineering
• Surgical Instrumentation

Background:

• Aortic valve grafting using homografts and pulmonary autografts is increasingly common.
• Proper orientation of these tissue valves during implantation is critical for optimal function and patient outcomes.
• Challenges exist in maintaining precise valve orientation during complex surgical procedures.

Purpose of the Study:

• To develop and evaluate an easily constructible and usable holder for maintaining tissue valve orientation during aortic valve grafting.
• To provide a practical solution for surgeons to ensure correct placement of homografts and pulmonary autografts.

Main Methods:

• Design and fabrication of a novel valve conduit holder using readily available surgical theater materials.
• Clinical application of the holder in over 50 aortic valve grafting procedures.
• Assessment of the holder's efficacy in maintaining tissue valve orientation.

Main Results:

• The developed holder is simple to construct and intuitive to use in the operating room.
• The holder effectively facilitated correct orientation of tissue valves during implantation.
• The device proved to be an essential aid in over 50 patient cases.

Conclusions:

• The novel valve conduit holder is a valuable tool for improving accuracy in aortic valve grafting.
• This easily accessible device enhances surgical precision for homograft and pulmonary autograft placement.
• The holder contributes to better surgical outcomes by ensuring correct tissue valve orientation.
