A method for ablating tissue is provided that comprises navigating an electrophysiology catheter to the site of the ablation, applying an ablating electrode on the electrophysiology catheter to the tissue to be ablated, applying energy to the electrode to ablate the tissue adjacent the electrode, ultrasonically imaging the site of the ablation, and re-ablating the tissue if the ultrasound imaging does not show a satisfactory ablation. Another embodiment of a method for ablation is provided that comprises forming a line of ablation by applying energy to an electrode to ablate the tissue adjacent the electrode, and ultrasonically imaging the line of ablation to locate points on the line that do not show satisfactory ablation. For points of unsatisfactory ablation, the method provides for navigating an electrophysiology catheter to at least one point on the line that does not show satisfactory ablation, and ablating the tissue at the point.
