Rare association of tetralogy of Fallot and aortic valve stenosis. Autopsy findings after failed balloon aortic valvuloplasty.
We report the case of a neonate with a rare association of tetralogy of Fallot and aortic valve stenosis, who died following percutaneous balloon valvuloplasty. Postmortem examination confirmed a tetralogy of Fallot morphology with a markedly hypoplastic pulmonary tree, hypertrophy of both ventricles, and a thickened and dysplastic aortic valve. Valvuloplasty was not effective despite the presence of a fissure in the cusp. The findings suggest that the left ventricular impairment and associated anomalies, with or without a dysplastic valve may contribute to the failure of balloon valvuloplasty in neonates with critical aortic valve stenosis.
