Abstract :
Atrial fibrillation is the most common form of arrhythmia. Consequences for patients are discomfort, blood clot formation and a high risk of embolic stroke. The choice of therapy is patient-dependent and is usually based on the degree of disability and the associated symptoms. Surgical/catheter ablation is a therapeutical procedure, which consists in creating lines of conduction block to interrupt maintenance of atrial fibrillation. The purpose of this paper is to evaluate different ablation patterns by means of a computer model of human atria. The importance of ablation lines in the right or left atrium is studied and compared to Maze-type procedures, which represent the standard in ablation therapy.
