Left ventricular volume after correction of isolated aortic coarctation inneonates

To determine the capacity of the left ventricle to expand after biventricul ar repair of left ventricular (LV) outflow tract obstruction, we studied pr e- and postoperative echocardiographic variables from 14 infants (< 2 month s old) who underwent successful repair of isolated aortic coarctation. We s how that in this lesion, LV volume is a dynamic entity, and that the left v entricle achieves a larger cavity size once surgery relieves compression an d normalizes loading conditions.
