Effect of Balloon Dilatation on Aortic Stenosis Assessed by 3-Dimensional Echocardiographic Reconstruction
A10-year-old boy with aortic valve stenosis treated by surgical valvotomy when he was 6 months old underwent balloon dilatation of recurrent aortic stenosis. The procedure was performed through the right femoral artery under general anesthesia with mechanical ventilation. The aortic valve was dilated with a balloon 20 mm in diameter. The peak systolic gradient dropped from 120 to 30 mm Hg after the procedure. Postprocedural aortography showed mild aortic regurgitation.
Multiplane transesophageal echocardiographic images of the aortic valve were acquired with a rotational scan before and after balloon dilatation. Three-dimensional (3D) views from the aorta were reconstructed (TomTec). The anatomy of the aortic valve and effects of the balloon dilatation are shown on the 3D views (Figures 1 through 3⇓⇓⇓).
