A biophysical model of atrial fibrillation to define the appropriate ablation pattern in modified maze.

OBJECTIVE The surgical Maze III procedure remains the gold standard in treating atrial fibrillation (AF); however due to clinical difficulties and higher risks, less invasive ablation alternatives are clinically investigated. The present study aims to define more efficient ablation patterns of the modified maze procedure using a biophysical model of human atria with chronic AF. METHODS A thre...

Inequalities for Left Atrial Ablation.

Ablation Via the Left Atrial Appendage

Method Fourteen consecutive patients with long term and short term persistent atrial fibrillation were the basis of this report. On full cardiopulmonary bypass, radiofrequency clamps were applied to the epicardial left atrial tissue surrounding the right and left pulmonary veins, separately. The left atrial appendage was amputated on the arrested heart. Via that defect, an epicardial to endocar...

Left atrial volume measurements before and after left atrial ablation for the treatment of atrial fibrillation

Background Recent studies have demonstrated the usefulness of CMR imaging in the management of patients with cardiac arrhythmia. CMR imaging allows for more accurate measurement of various cardiac dimensions. Significant changes in LA volumes have previously been documented in patients who have undergone ablation therapy. However, these studies have relied on simple two dimensional measurement ...
