[Coronary artery disease - definitions and epidemiology]

Over the past two centuries, coronary artery disease has emerged as an important cause of morbidity and death in industrialized nations. Increased life expectancy and changed habits (regarding nutrition, physical activity, and smoking) have contributed to this dramatic epidemiologic shift. During the last 50 years, a decline in the coronary artery disease mortality rate was observed due to therapeutic advances and prevention measures targeted at people with coronary artery disease and those potentially at risk for it. This article highlights important epidemiologic data and some definitions in the context of coronary artery disease are presented.

Esophagus imaging for catheter ablation of atrial fibrillation: comparison of two methods with showing of esophageal movement

This study aims to evaluate whether visualization and integration of the computed tomography (CT) scan of the left atrium (LA) and the esophagus into the three-dimensional (3D) electroanatomical map the day before ablation is accurate compared with integration of an esophagus tag into the electroanatomic LA map visualizing the anatomic relationship during the radiofrequency ablation or whether esophagus movement prohibits esophagus visualization the day before ablation.
