Treatment involves surgical resection and continued monitoring with echocardiography thereafter. There are no guidelines on the frequency and duration of monitoring. Presented here is the case of a 46-year-old man who underwent resection of four-chamber cardiac myxoma 15 years previously. He had stopped surveillance 3.5 years previously because the annual echocardiogram for the past 10 years did not show any evidence of recurrence. However, routine echocardiography revealed a right ventricular mass consistent with myxoma on pathology. This case not only highlights the rarity of four-chamber myxoma and its recurrence but also teaches an important lesson to continue surveillance in asymptomatic patients even after many normal echocardiograms.
