Division of Cardiology, The Children s Hospital of Philadelphia, Philadelphia, Pennsylvania, USA
Am J Cardiol 106:1029-33. 2010..Presence of prolonged cardiac repolarization may contribute to the high incidence of periprocedural mortality in these patients. All patients with WS should be screened for cardiac repolarization abnormalities, especially before surgery...

Arkansas Children s Hospital, Little Rock, AR, USA
Am J Cardiol 111:1501-4. 2013..Elastin haploinsufficiency does not appear to be the etiology of QTc prolongation in patients with WS. The possible contribution of other genes on 7q11.23 to QTc prolongation in WS should be investigated...
