Surgical ablation is a procedure that essentially blocks abnormal areas of heart tissue from conducting electrical impulses. One of the uses for surgical ablation is to prevent cardiac tissue from conducting abnormal heart rhythms, ensuring that the heart will beat more regularly.
With high-intensity focused radio-frequency or microwave energy, physicians create very precise, consistent and effective ablative lesions. By adjusting power and wavelength, the energy is focused to ablate precise areas of cardiac tissue without impacting surrounding tissue or blood vessels.
Surgical ablation is often performed on patients already receiving cardiac valve replacement or repair, or coronary artery bypass, due to the fact that a surgeon already has access to the patient’s heart. In some cases, it can be done minimally invasively as a stand alone procedure.
