Influence of left ventricular cavity size on interventricular shunt timing and outcome in neonates with coarctation of the aorta and ventricular septal defect.
In this study, we reviewed the records and echocardiograms of 39 consecutive patients with coarctation of the aorta and ventricular septal defect who underwent neonatal coarctation repair to examine the influence of left heart size on ventricular shunting and outcome. We found smaller left heart structures (initial mitral and aortic annular diameters) to be associated with diastolic interventricular shunting and to be predictive of the development of mitral or aortic and/or subaortic stenosis.
