Cardiovascular complications of mantle field radiation: a case series.

Our case series emphasizes the need for an index of suspicion for radiation-related cardiovascular changes in patients who have a history of mantle radiation, especially in younger patients. This was especially pertinent in the case of our first patient who presented a diagnostic challenge due to certain patient factors. Our second patient is a case of subclavian artery stenosis which is less frequently reported as a complication of mantle radiation in the literature.
