[citation needed] The potential complications include bleeding, blood clots, pericardial tamponade, and heart block, but these risks are very low, ranging from 2.6 to 3.2%. For non-paroxysmal atrial fibrillation, a 2016 systematic review compared catheter ablation to heart rhythm drugs. After 12 months, participants receiving catheter ablation ...
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
Numerous studies in animals have demonstrated the safety and efficiency of IRE as a non-thermal ablation modality for pulmonary veins in the context of atrial fibrillation treatment. [101] In 2023, irreversible electroporation is being widely used and evaluated in humans, as cardiac ablation therapy to kill very small areas of heart muscle.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Atrial fibrillation is one of the most common cardiac arrhythmias. In general, it is an irregular, narrow complex rhythm. However, it may show wide QRS complexes on the ECG if a bundle branch block is present. At high rates, the QRS complex may also become wide due to the Ashman phenomenon. It may be difficult to determine the rhythm's ...
Atrial fibrillation is a type of arrhythmia characterized by rapid and irregular heart rhythms due to irregular atrial activation by the atrioventricular (AV) node. [7] In the pathogenesis of atrial fibrillation, there is no effective pumping of blood into either the pulmonary or systemic circulation from the left ventricle of the heart.
In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [50] Atrial fibrillation and atrial flutter resulted in 112,000 deaths in 2013, up from 29,000 in 1990. [26] Sudden cardiac death is the cause of about half of deaths due to cardiovascular disease or about 15% of all deaths globally. [51]
