The long-term results of using 3-patch technique for supravalvular aortic stenosis
Main Article Content
Abstract
The objective of this study evaluated the results of using 3-patch technique for supravalvular aortic stenosis [1]
Methods: This was a review of seri cases: using 3-path technique for supravalvular aortic stenosis from 1/2012 to 12/2018
Results: There were 8 patients who underwent using 3-patch technique, include 5 males and 3 females. The mean of age was 12,4 years (range 4 to 32 year), 7 childrents and 1 adult. The left ventricular outflow tract gradient was 62 mmHg. The time of cardiopulmonary bypass, aortic clamping and ventilator were: 104 minutes; 72 minutes. 7 patients were used pericardium path and 1 patient was another graft. There was not intrahospital mortality. Echocardiography post -operation: left ventricular outflow tract gradient was 11,8 mmHg. During follow-up time 7,8 years after surgery, there was no late death; there were 3 patients who had to reoperation include 2 patient with stenotic distal anastomosis postoperation 5 years and 1 patient with severe aortic valve stenosis postoperation 8 years Conclusion: The long-term of using 3-patch technique for supravalvular aortic stenosis were satisfaction and longer follow-up was essential to find-out about risks of reoperation.
