A 5-year-old girl with an aortic stenosis correction comes to the office for a follow-up visit for acute lymphoblastic lymphoma. She initiated chemotherapy a week before through a peripherally inserted central line. She reports being ‘tired all the time’ and has been bruising easily. Her vital signs are within normal limits. Physical examination shows several tenders, non-blanching petechiae on the pads of the fingers and toes; several dark, non-tender petechiae on her palms and soles; and small, linear hemorrhages under her fingernails. Fundoscopic examination shows various small areas of hemorrhage on the retinae bilaterally. Cardiac examination is notable for a II/VI systolic ejection murmur that seems to have worsened in comparison to the last visit. Which of the following is the most likely cause?
