Monitoring of a paediatric cardiac tumour over 14 years

In 1996, a previously well 5 month-old infant presented with ventricular tachycardia requiring cardioversion. Echocardiography revealed a 5 cm myocardial tumour involving the ventricular septum and right ventriclular postero-inferior wall (figure 1A). There was no obstruction to ventricular inflow or outflow, and the patient was managed conservatively (figure 1B, see online supplementary video 1*). Figure 1 Serial multimodality imaging of cardiac fibroma. An echocardiogram take at 1 year of age demonstrates a large interventricular septal mass (A) which did not obstruct the left ventricular outflow tract (B). Three years later a CT scan of the chest demonstrated little change in size of the mass (C). A decade later, at age 14 years, cardiovascular magnetic resonance demonstrates little change in tumour …
