1. A method, comprising:
receiving multiple tags along an ablation curve that covers a partial circumference over an inner wall of a cardiac chamber of a heart of a patient; and
using the tags, completing the ablation curve to a full circumference over the inner wall to eliminate a conduction gap in the ablation curve,
wherein completing the ablation curve comprises computing, for an existing tag on an anterior wall of the cardiac chamber, a new tag location on a posterior wall of the cardiac chamber by:
defining a plane on an anatomical map of the cardiac chamber associated with the anterior wall; and
projecting the existing tag along an axis orthogonal to the plane to the posterior wall.
