title: Aortic Stenosis or Atresia with Associated Hypoplasia of the Left Ventricle: Imaging Before and After Reconstructive Surgery.
abstract: Aortic atresia or stenosis, when associated with hypoplasia of the left ventricle, presents the cardiac surgeon with a challenging reconstruction. Many preoperative and intraoperative decisions are now made on the basis of ultrasound data. Furthermore, echocardiography provides the most convenient way to time the stages of the reconstructive sequence and assess the hemodynamic result. (ECHOCARDIOGRAPHY, Volume 13, May 1996)
