RATIONALE Familial sick sinus syndrome (SSS) has been linked to loss-of-function mutations of the SCN5A gene, which result in decreased inward Na(+) current, I(Na). However, the functional role of I(Na) in cardiac pacemaking is controversial, and mechanistic links between mutations and sinus node dysfunction in SSS are unclear. OBJECTIVE To determine mechanisms by which the SCN5A mutations im...

Segmentation of the left atrium is vital for pre-operative assessment of its anatomy in radio-frequency catheter ablation (RFCA) surgery. RFCA is commonly used for treating atrial fibrillation. In this paper we present an semi-automatic approach for segmenting the left atrium and the pulmonary veins from MR angiography (MRA) data sets. We also present an automatic approach for further subdividi...

Background Increased left atrial volume and reduced atrial emptying are predictors of adverse cardiac events in adults. The atrium in single ventricle hearts contributes to ventricular filling to a greater degree than in normal hearts. Standardized methods of determining atrial function in single ventricles are lacking. We aimed to assess the feasibility and reproducibility of quantifying atria...
