HIFU for Arrhythmia

A racing heart is a hallmark symptom of atrial fibrillation. Radiofrequency ablation can break the misfiring electrical connections but often needs to be re-done.

Now a new type of ablation procedure is under review at the hospital of the University of Pennsylvania, using high intensity ultrasound to make a complete break all at once. The prorhythm system uses a balloon-tipped catheter to direct high intensity focused ultrasound at the opening of pulmonary veins. The directed ultrasound scars the tissue and breaks the irregular electrical connections.
