Abstract
|
|
|
The localized form of subaortic stenosis shows a spectrum of pathological lesions varing from discrete membrane to a thickened fibromuscular collar. Aortic valve is commonly involved late in the process resulting in regurgitation.
Because of the likelihood of the progressive obstruction and aortic regurgitation, early elective operation should be considered for the patient with subaortic stenosis.
We experienced a case of localized fibromuscular subaortic stenosis associated with aortic regurgitation. Excision of the fibromuscular ridge and septal myectomy-myotomy relieved the subaortic stenosis. Regurgitant aortic valve was repaired by
peeling
away the fibrotic tissue on the cusps and subcommissural annuloplasty at the each commissural area.
On postoperative echocardiographic examination, the systolic pressure gradient between left ventricle and aorta decreased markedly and the aortic regurgitation was not detected at all.
