Severe unicuspid aortic valve stenosis: VACTERL association

Description

A 24-year-old man with a known history of horseshoe kidney leading to end-stage renal disease, scoliosis and small ventricular septal defect consistent with VACTERL association, who presented with worsening dyspnoea on exertion. Transthoracic echocardiogram (TTE) showed a unicuspid aortic valve (UAV) with severe aortic stenosis (AS) (valve area of 0.6 cm2 and mean gradient of 44 mm Hg). TTE also showed moderate aortic insufficiency and severely reduced left ventricular systolic function with estimated ejection fraction of 20%. Transoesophageal echocardiography (TEE) confirmed a UAV with single commissure located anteriorly (figure 1A–D; online  and ) and severe AS (figure 1B, C). In preparation for surgical repair, chest CT angiogram showed dilated ascending aorta measuring 4 cm with no evidence of aortic dissection. The patient underwent aortic valve replacement surgery with 21 mm CarboMedics mechanical valve. TEE showed a well-seated prosthesis without evidence of paravalvular leak (figure 1E). The patient...
