title: Left ventricular volume after correction of isolated aortic coarctation in neonates.
abstract: To determine the capacity of the left ventricle to expand after biventricular repair of left ventricular (LV) outflow tract obstruction, we studied pre- and postoperative echocardiographic variables from 14 infants (< 2 months old) who underwent successful repair of isolated aortic coarctation. We show that in this lesion, LV volume is a dynamic entity, and that the left ventricle achieves a larger cavity size once surgery relieves compression and normalizes loading conditions.
