An extremely rare complication of catheter ablation of atrial fibrillation is the formation of a fistula (abnormal connection) between the left atrium of the heart and the oesophagus (‘gullet’). During the ablation procedure, one or more catheters (thin, flexible tubes) are inserted into your body. Rarely, damage can occur to the coronary arteries as a result of catheter ablation, in extreme cases resulting in damage to the heart muscle (‘myocardial infarction’). Catheter ablation is a nonsurgical treatment for irregular heartbeats, including atrial fibrillation, that locates and destroys the abnormal electrical. Ablation safely creates a small scar that blocks. Cases of permanent phrenic nerve palsy have been reported. During an ablation procedure, we target areas of your heart tissue responsible for causing the arrhythmia. This may cause breathlessness on exertion, which may take up to a few months fully to recover. The right phrenic nerve, which supplies the right side of the diaphragm, may occasionally be affected by catheter ablation for atrial fibrillation. If this does not recover, it may be necessary to fit a pacemaker. The heart’s normal electrical conduction system (the atrioventricular node and His bundle) may occasionally by affected by catheter ablation for supraventricular tachycardia. Catheter occasion may occasionally result in damage to structures close to the area of the heart that needs to be treated in order to cure the heart rhythm problem. ![]()
