Faulty cardiac repolarization reserve in alternating hemiplegia of childhood broadens the phenotype.
Alternating hemiplegia of childhood is a rare disorder caused by de novo mutations in the ATP1A3 gene, expressed in neurons and cardiomyocytes. As affected individuals may survive into adulthood, we use the term 'alternating hemiplegia'. The disorder is characterized by early-onset, recurrent, often alternating, hemiplegic episodes; seizures and non-paroxysmal neurological features also occur. ...
OBJECTIVES We investigated whether the presence of right ventricular (RV) abnormalities detected by cardiovascular magnetic resonance (CMR) predict adverse outcome in patients presenting with frequent premature ventricular complexes (PVCs) of left bundle branch block (LBBB) morphology. BACKGROUND CMR is a component of the diagnostic workup for the differential diagnosis between arrhythmogenic...
BACKGROUND Congenital left ventricular aneurysm (LVA) and diverticulum (LVD) are rare cardiac anomalies frequently associated with electrocardiogram (ECG) abnormalities. The aim of this study was to evaluate the long-term prognosis in such patients. METHODS AND RESULTS A total of 108 patients with LVA or LVD having ECG-abnormalities were assessed. The patients were classified into 2 groups ...
Two-dimensional echocardiographic studies were prospectively performed in 93 patients with systemic lupus erythematosus (SLE) to discover the incidence and spectrum of cardiac abnormalities and to relate these findings to the presence of high levels of anticardiolipin antibodies. Assessment of the intracardiac anatomy was also performed in an additional 12 patients who had increased anticardiol...
OBJECTIVES Our aim was to determine whether location of wall motion abnormalities (WMAs) during exercise echocardiography provides independent prognostic value. BACKGROUND The effect of the location of WMAs during stress echocardiography on prognostic outcome is unknown. METHODS We studied 4,347 patients (mean age, 61 +/- 12 years; 2,230 men) with known or suspected coronary artery disease ...
CMR is valuable in the evaluation of congenital heart disease (CHD). Traditional flow imaging sequences involve cardiac and respiratory gating, increasing scan time and susceptibility to arrhythmias. We studied a real-time color-flow CMR system for the detection of flow abnormalities in 13 adults with CHD. All 16 congenital flow abnormalities previously detected by echocardiography were visuali...
