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

## TL;DR

A young adult was diagnosed with a heart tumor during a routine school check-up in Japan and successfully treated to prevent recurrence.

## Contribution

This case highlights the effectiveness of cryoablation after tumor resection in preventing cardiac tumor recurrence.

## Key findings

- A heart murmur detected during a routine school check-up led to the diagnosis of a cardiac myxoma.
- Cryoablation following tumor resection may reduce the risk of tumor recurrence.
- Regular medical check-ups can prevent sudden death from undetected cardiac tumors.

## Abstract

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.
