Abstract T P368: High Risk of Mortality in Congenital Heart Disease Patients Who Suffer Strokes

Introduction: Congenital heart disease (CHD) patients have many risk factors for stroke. Our goal was to describe CHD patients who suffered strokes and determine factors associated with in-hospital mortality. Methods: Patients with acquired or CHD who suffered a stroke (radiologic evidence of arterial/venous infarct; subdural, subarachnoid, parenchymal or epidural hemorrhage) from 1/2010-5/2014 at our hospital were identified. Patient charts were retrospectively reviewed. Results: Seventy-five stroke patients were identified. Median age at diagnosis was 5.7 months (IQR 0.6, 33.2), and 26 (35%) were neonates. Twenty-six patients (35%) had single ventricle CHD, and 9 (12%) had Fontan circulations. Seven patients (9%) presented with neurologic symptoms at home. The remainder developed neurologic findings after being hospitalized for a median duration of 9.5 days (IQR 4.0, 21.8). Thirty-four patients (45%) presented with clinically evident neurologic deficits (e.g. weakness, seizures). Forty-seven patients (6...
