Summary
A modified Z-plasty effectively reduces moderate ascending aortic dilation during other cardiac surgeries. This technique offers a safe and valid option for patients not requiring more extensive aortic repair.
Area of Science:
- Cardiovascular Surgery
- Aortic Diseases
- Cardiac Procedures
Background:
- Ascending aortic enlargement can occur with other heart conditions.
- Moderate dilation (<6 cm) may be addressed during concurrent cardiac surgery.
Purpose of the Study:
- To evaluate the efficacy of a modified Z-plasty technique for reducing ascending aortic diameter.
- To assess the safety and outcomes of this aortic reduction method in patients undergoing other cardiac procedures.
Main Methods:
- A modified Z-plasty using an S-shaped incision was performed in 23 patients.
- Procedures included aortic valve replacement, coronary bypass, and subaortic stenosis resection.
- Preoperative and postoperative echocardiography measured aortic diameters.
Main Results:
- The mean aortic diameter decreased significantly from 5.0 cm to 3.1 cm intraoperatively (p<0.01).
- Postoperative follow-up showed stable diameters, with no reported recurrences of aneurysms.
- All patients tolerated the procedure well.
Conclusions:
- The modified Z-plasty is a valid technique for moderate ascending aortic dilation in patients undergoing concomitant cardiac surgery.
- This approach provides a safe alternative when aggressive aortic intervention is not indicated.
