Resection of a Large Left Ventricular Fibroma in a Young Adult

A 20-year-old woman, weighing 50 kg, presented with exertional shortness of breath and palpitations. An echocardiogram showed a left ventricular tumor that distorted the left ventricular cavity. Cardiac computed tomography (CT) and magnetic resonance imaging (MRI) showed a well-circumscribed mass in the lateral wall of the left ventricle that had a density similar to fibroma, appearing benign in nature. 

Through median sternotomy and after aortic and bicaval cannulation, cardioplegic arrest was achieved, and the mass was completely resected. The remaining large cavity was obliterated, and its capsule was closed with two layers of running polypropylene sutures supported with Teflon felt strips. The patient was subsequently weaned off cardiopulmonary bypass without difficulty, and a postoperative echocardiogram showed good biventricular function. She was extubated a few hours after surgery, and the remainder of her postoperative course was uneventful. 

Histopathology confirmed this was a benign fibroma with no signs of atypia or malignancy. The patient continued to do well during her follow-up, with resolution of her symptoms.
