title: Pericardial patch enlargement of Blalock-Hanlon atrial septectomy.
abstract: A modified Blalock-Hanlon operation is described, in which both the right and left atriotomies were bridged by a generous pericardial patch. This patch significantly enlarged the interatrial communication and markedly increased arterial blood saturation.
