Conclusion:

The use of VMAT and TFiF techniques is feasible for the treatment of the left breast in patients with CIED. The minimum distance of 2.5 cm found between the CIED and the target is a discriminating factor for proceeding with treatment; however, for shorter distances, the feasibility of treatment must be investigated because some patients may still meet clinical requirements.
