However, they are not zero and some can be serious. Serious risks associated with atrial flutter ablation are very rare. This is anticipated especially as blood thinners are usually continued. It is not uncommon to experience some minor bruising from the access site in the leg. Frequently, atrial flutter ablation is often included in an ablation procedure for atrial fibrillation. Your doctor will advise which medications are still required following the procedure. Importantly, blood thinners (if present) may not be ceased following ablation, as co-existing atrial fibrillation (or AF) is common. The added benefit is that medications aimed at slowing the heart rate down, known as rate controlling medications (such as beta blockers, digoxin, amiodarone etc.), may be reduced or in some cases ceased following ablation. Why is it done?Ītrial flutter ablation is usually performed to eliminate the symptoms (or palpitations) and deleterious effect on the heart of the atrial flutter. Typically, this ablation is performed along the floor of the right atrium (in an area known as the cavo-tricuspid isthmus), although occasionally, in patients having had previous surgery, ablation may be needed elsewhere. This effectively eliminates the atrial flutter. The procedure is aimed at disrupting this electrical circuit by the delivery of some heat energy (in the form or radiofrequency energy) to part of the circuit, so impulses can no longer travel around this circuit. A well-established treatment atrial flutter is catheter ablation.Ītrial flutter is caused by an abnormal electrical circuit that usually exists around the valve on the right side of the heart (the tricuspid valve). Atrial flutter is an electrical disturbance of the heart (or arrhythmia) which can result in fast heart rates, palpitations and occasionally reduce the heart function resulting in heart failure.
