Surgical treatment of bicuspid aortic valve with aortic stenosis

Main Article Content

Abstract

Background: Patients with bicuspid aortic valve may develop isolated aortic valve disease, including isolated aortic stenosis. This disease progresses over a long period of time leading to simultaneous damage of the valves and aorta. Surgery is an effective treatment of both lesions simultaneously. This study objective is to describe the characteristic features of the diagnosis and surgery results of this disease.


Methods: All of patients diagnosed aortic stenosis due to bicuspid aortic valve were performed aortic valve replacement and asscociated aortic lesions. This retrospective descritptive study used data from the Hanoi Medical Uninversity Hospital from 3/2020 to 3/2023.


Results: This study include 25 patients who met review criteria. Aortic stenosis was in all of patients associated with ascending aortic aneurysm. Mean aortic gradient was 56,7mmHg and 36,0% of patients had ascending aortic diameter above 45mm. The most common morphology of bicuspid aortic valve was right – left coronary leaflet. 8,0% of patients had poor left ventricle function (EF < 30%). 36,0% of patients were perfomed single aortic valve replacement, 60,0% were corrected simultaneously lesions of aortic valve and ascending aorta in which 24,0% using wrapping with dacron graft. Complications: One death due to intraoperative Stanford A aortic dissection; one bleeding due to lateral wound close distal aortic anastomosis required an operation and one of sternal instability require a sternal plasty. 96,0% of patients have discharged uneventfully.


Conclusions: Surgery is an effective treatment of both lesions simultaneously of aortic valve and descending aorta in aortic stenosis due to bicuspid aortic valve malformation. Wrapping of the ascending aorta may be useful in patients who need to undergo aortic valve surgery without increasing the risk of surgery.
