title: Tetralogy of Fallot with atresia of the left pulmonary artery: surgical repair using a homograft aortic valve.
abstract: Two cases of tetralogy of Fallot with unilateral absence of the left pulmonary artery are presented. Both patients required a valve-retaining homograft because of severe pulmonary valve incompetence following previous surgical correction. This uncommon anatomic variant presents special surgical problems, as pointed out in a review of the literature.
