Atrial Fibrillation

Atrial fibrillation, which can also be referred to as AF or Afib, is a common condition in which the upper chambers of the heart beat rapidly in an uncontrolled manner. The irregular beating affects blood flow and may result in a fluttering feeling in the patient's chest. Doctors may elect to treat the patient's symptoms with antiarrhythmic drugs or prescribe anticoagulant medications due to the heightened risk of stroke.


If medications are not effective in controlling atrial fibrillation, a physician may recommend catheter ablation. Ablation is a non-surgical technique that uses several imaging and monitoring systems to deploy catheters in the heart via an artery or vein. The physician is then able to locate the electrical abnormality, deliver various forms of energy to the affected area, and check to determine if the arrhythmia has been isolated. Many patients who receive ablation are converted into a normal rhythm or experience a reduction in the number of atrial fibrillation episodes and severity of symptoms. VytronUS is developing a next generation imaging and catheter system using ultrasound energy to treat electrical abnormalities, which may improve the safety and efficacy profile of the ablation procedure as compared to current techniques.
