Atrial Fibrillation Ablation
What is it?
Radiofrequency catheter ablation is one of the most technically advanced methods of treating heart rhythm disturbances. It involves the placement of specialised catheters into the heart via a vein in the leg. The catheters are used to deliver radiofrequency energy to precise regions within the heart to cure abnormal heart rhythms.
A computerised mapping system allows precise visualisation and location of these regions for patients in Atrial Fibrillation.
Preparation
You will have a CT (computed tomogram) or magnetic resonance imaging of the heart and a transoesophageal echocardiogram prior to the procedure.
Fasting is required for 6 hours prior to the admission time. Some medications, such as blood thinners (ie. Warfarin) or heart rhythm drugs, may need to be stopped several days before the procedure - the cardiologist will advise you on a case by case basis. You should expect to stay in hospital for 1-2 nights.
Results
Your doctor will inform you of the results at the end of the procedure. A follow up appointment will be made for 2 weeks later in the consulting rooms.
If you are a patient undergoing this procedure and you have any further queries, please raise them with your cardiologist.
