title: [The role of antiarrhythmic surgery in 2004].
abstract: In 2004, surgery for cardiac arrhythmias addresses essentially atrial fibrillation. Surgery is only a rare alternative for other cardiac arrhythmias in center that still have the surgical skill. Surgery for atrial fibrillation has the definite advantage of concomitant exclusion of the left atrial appendage which is the predominant site of intra-atrial thrombi with the associated risk of severe thrombo-embolic events. Our experience with surgery for lone atrial fibrillation, using the Corridor III operation, shows that surgery is associated with high efficacy and long term control of arrhythmia when the surgical technique is well performed. Failures were associated with incomplete line of block or exclusion. This experience shows the necessity of postoperative EP testing. Initially performed using open heart technique, surger for atrial fibrillation is now performed using mini-invasive technique. Indications for surgery for lone atrial fibrillation will decreased while other strategies are developing. To remain competitive surgery must have high efficacy and use mini-invasive techniques. i.e.: closed off pump beating heart via port access. Surgery for atrial fibrillation concomitant with other cardiac surgical repairs yields remarkable results, without increased surgical risk. Their indications go beyond mitral valve pathology. Future developments imply the following conditions: atrial surgery must not increase morbidity, and its cost-effectiveness must be documented. Combined surgery must be testable and tested to gain valid pathophysiological data to improve surgical rationales. Its impact in terms of survival, prevention of thrombo-embolic events and quality of life will be documented by clinical trials.
