When a pacemaker sits on the left chest, the device can obscure left breast tissue on a standard cranio-caudal view. Adding a different angle helps see areas that might be hidden. The left mediolateral oblique projection provides a side-angle view of the left breast, capturing the axillary tail and upper outer quadrant while shifting the breast tissue relative to the device. This reduces overlap with the pacemaker and improves visualization of tissue near the chest wall, making it the best complementary projection to use in this scenario. The other options either image the wrong side or aren’t the targeted oblique projection typically used to enhance evaluation when a left-sided device is present.
