Aortic Annular Enlargement with Modified Y-Incision Technique Devised from Preoperative Three-Dimensional Computed...

Area of Science:

• Cardiovascular Surgery
• Cardiac Anesthesia
• Medical Device Technology

Background:

• The Y-incision technique for aortic annular enlargement, introduced in 2021, allows significant size increase without impacting the left atrium or mitral valve.
• A specific patient case presented a challenge due to the left coronary artery ostium's proximity to the left-non commissure, making the standard Y-incision potentially hazardous.

Purpose of the Study:

• To describe a modified aortic annular enlargement technique to address anatomical limitations encountered with the standard Y-incision method.
• To present the L-incision technique as a safe and effective alternative for aortic annular enlargement in specific anatomical scenarios.

Main Methods:

• A new surgical approach, termed the L-incision technique, was developed to enlarge only the noncoronary annulus.
• This technique was employed in a case where the left coronary artery ostium was situated near the left-non commissure, posing a risk with the Y-incision.
• Preoperative three-dimensional imaging was utilized for detailed anatomical assessment and surgical planning.

Main Results:

• The L-incision technique successfully enlarged the aortic annulus without compromising the left atrium or mitral valve.
• The modified approach mitigated the risk associated with the proximity of the left coronary artery ostium.
• Preoperative 3D imaging proved valuable in planning the aortic annular enlargement procedure.

Conclusions:

• The L-incision technique is a viable and safe alternative for aortic annular enlargement, particularly in cases with challenging anatomy near the left coronary artery ostium.
• This modification of the Y-incision technique expands the options for aortic annular enlargement, enhancing surgical safety and applicability.
