Abstract
BackgroundCardiac fibroma is rarely encountered in children, and even more rare in neonates. We herein report a case of a 5-month-old female with severe right ventricular outflow tract obstruction caused by a large right ventricle fibroma that was successfully surgically resected.Case presentationThis report describes the case of a 5-month-old female infant with a large mass measuring 26 × 22 mm in the right ventricle cured successfully with surgery. Physical examination revealed a harsh S1 sound and a grade IV systolic murmur on the left sternal border. Surgical resection was indicated due to severe right ventricular outflow tract obstruction and further follow-up evaluation was uneventful.ConclusionThe surgical procedure to excise such a large cardiac fibroma in a 5-month-old infant is feasible and safe.
Highlights
Cardiac fibroma is rarely encountered in children, and even more rare in neonates
An incision was made on the free wall of right ventricle, exposing a white, tenacious, noncapsulated egg-like neoplastic growth protruding into the right ventricular chamber, with its base arising from interventricular septum
The incidence of primary cardiac tumors in children has been reported to be 0.03–0.32%, with fibromas accounting for 25%
Summary
We report a case of a 5-month-old female with severe right ventricular outflow tract obstruction caused by a large right ventricle fibroma that was successfully surgically resected. A transthoracic echocardiogram was performed, which revealed a homogeneous mass measuring 26 × 22 mm (Fig. 1a), with a broad base from ventricular septum and the body protruding into the right ventricular chamber, causing an accelerated right ventricular outflow (Vmax = 4.0 m/s, PG = 64 mmHg) with an obstruction (Fig. 1b). The cardiac-magnetic resonance imaging confirmed the presence of a solid mass appending to the right side of
