Detection, Prevention, and Treatment of Asymptomatic Myxoma in a Young Adult Patient: A Case Report.

We present a case of myxoma originating from the right ventricular outflow tract. The patient was referred to our clinic after detecting a heart murmur at a routine school medical check-up, which is unique to Japan. He was treated with tumor resection and cryoablation to prevent recurrence. Cryoablation after tumor removal has the potential to prevent the recurrence of cardiac tumors. This case further emphasized the importance of regular school medical check-ups because it prevented sudden death.
