Left Atrial Volume in Children Without Heart Disease and in Those With Ventricular Septal Defect or Patent Ductus Arteriosus or Hypertrophic Cardiomyopathy

In adults, the left atrial (LA) volume has been shown to reflect diastolic function and is a powerful predictor of cardiac morbidity and mortality. Normative LA volume values in children and the effect of loading conditions on the LA volume in those with congenital heart disease are lacking. The purposes of the present study were to (1) establish normal LA volume values for children, (2) assess the effect of left ventricular volume loading...
