Atrial fibrillation catheter ablation adverse outcomes

Atrial fibrillation is a type of irregular heartbeat that originates in the upper chambers of the heart and can be treated by medical management, surgical repair or non-surgical treatment options such as catheter (radiofrequency) ablation.

During catheter ablation, a small thin flexible tube (catheter) with an electrode at the tip is threaded through arteries or veins in either the arm, groin, or neck and inserted onto various places in the heart that are generating abnormal electrical signals. The electrode delivers radiofrequency energy, high frequency radio waves that generate heat and cauterize (burn) the abnormal heart tissue. This burning, or ablating, prevents the pathway from conducting electricity eliminating its capacity to initiate an irregular heartbeat.

Catheter ablation for atrial fibrillation is a complex procedure and serious complications can occur such as death, bleeding or other serious events. The rate of complications during or following this procedure can depend on physician expertise, patient demographics such as age or gender, as well as patient comorbidities and risk factors such as a long history of atrial fibrillation/flutter, congenital heart disease, heart failure or heart valve disease.
