Atrial Fibrillation

This channel includes news and new technology innovations for the treatment of atrial fibrillation, also referred to as AF or afib. AF is a cardiac arrhythmia caused by irregular and often rapid heart rate. It is caused by the upper chambers (the atria) beating irregularly and uncoordinated with the lower  ventricle chambers of of the heart. Symptoms include weakness with heart palpitations and shortness of breath. The conditional can lead to an increased risk of stroke and heart failure. AF episodes can cause the blood in the atria to stagnate and form clots, usually within the left atrial appendage (LAA). The clots can flow to the brain and cause a stroke. Treatments include anticoagulation therapy to dissolve clots, catheter or surgical ablation and LAA occlusion

Medtronic announced clinical trial results from the STROKE AF trial demonstrating the superiority of the Reveal Linq Insertable Cardiac Monitor (ICM) to detect abnormal heartbeats, otherwise known as atrial fibrillation (AF), in both large and small vessel stroke patients compared to standard of care.

The U.S. Food and Drug Administration (FDA) expanded approval for Medtronic's Arctic Front Family of cardiac cryoablation catheters for the treatment of recurrent symptomatic paroxysmal atrial fibrillation (AFib). The indication is for episodes that last less than seven continuous days and the therapy can be used as an alternative to antiarrhythmic drug (AAD) therapy as an initial rhythm control strategy.
