Epicardial Mapping and Ablation of Cardiac Arrhythmias

摘要: Epicardial mapping and ablation of cardiac arrhythmias has been an important development in interventional electrophysiology. The fibrous serous pericardia are separated by a space that permits introduction guide wire using subxiphoid percutaneous approach. There two major sinuses the pericardial space. A sheath advanced over provides mean to introduce one or more catheters probes perform epicardially. Atrial require epicardial include unusual types atrial tachycardia accessory pathways. In patients with fibrillation atypical flutter, may be required obtain isolation elimination substrate. ischemic heart disease left ventricular dysfunction, as well dilated cardiomyopathy, infiltrative forms disease, originate epicardially prior performing endocardial ablation. numerous considerations requiring safety management undergoing Newer surgical hybrid procedures, from collaboration electrophysiology surgery, also provide new approaches procedures
