Left ventricular volume after correction of isolated aortic coarctation in neonates.
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.
