Abnormal Excursion of IVS in Postop TOF Patients Should Be Evaluated


Background: Left ventricular (LV) systolic dysfunction is not uncommon after surgical repair of tetralogy of Fallot (TOF). This can lead to less exercise capacity, arrhythmias, and sudden cardiac death. Different potential etiologies postulated include intraoperative myocardial ischemia, chronic myocardial hypoxia occurring prior to repair, LV dyssynchrony due to altered electrical activation, and abnormal interventricular interaction due to increased size of the right ventricle (R more...
