Summary
This study presents a novel internal circular suture annuloplasty technique for aortic valve repair. The method effectively reduces aorto-ventricular junction diameter, showing promise for mild annular dilatation.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Aortic Valve Repair
Background:
- Stabilizing the aorto-ventricular junction is crucial for successful aortic valve repair.
- Annular dilatation can complicate aortic valve procedures.
Purpose of the Study:
- To describe and evaluate a modified internal circular suture annuloplasty technique.
- To assess the efficacy of this technique in reducing aorto-ventricular junction diameter.
Main Methods:
- A continuous horizontal mattress suture using expanded polytetrafluoroethylene (CV-3) was employed.
- Four stitches per sinus were placed below cusp attachment, reinforced with pericardial pledgets.
- The technique was applied to 12 patients undergoing aortic valve repair.
Main Results:
- The aorto-ventricular junction diameter decreased from 25 ± 2 mm to 22 ± 1 mm (n=11).
- This reduction was maintained at a median follow-up of 41 months (n=10).
- Adequate reduction was not achieved in two patients with severe dilatation (≥27 mm).
Conclusions:
- The modified internal circular suture annuloplasty is a simple and seemingly durable technique.
- It demonstrates potential utility in managing mild annular dilatation during aortic valve repair.
