A papillary fibroelastoma of the tricuspid valve

Minimally invasive resection of heart valve papillary fibroelastoma: two case reports and review of the literature

BACKGROUND

Cardiac papillary fibroelastomas are rare, accounting for approximately 10% of all cardiac tumors, with 44% of cases located on the aortic valve and only 15% of cases located on the tricuspid valve. However, the optimal management of papillary fibroelastomas remains varied.

CASE PRESENTATION

We present two successful instances of treating heart valve papillary fibroelastomas through minimally invasive surgery. These cases involved heart valve papillary fibroelastomas located in two common sites: the aortic valve on the left heart, which was accessed via an upper hemi-sternotomy, and the tricuspid valve on the right heart, which was accessed via beating heart total thoracoscopy.

CONCLUSION

The article consistently demonstrates the effectiveness of a minimally invasive surgical approach in managing heart valve papillary fibroelastomas. This study provides further evidence by presenting two cases of heart valve papillary fibroelastomas - one on the aortic valve and the other on the tricuspid valve - that were successfully treated using this approach, resulting in favorable outcomes.

Papillary fibroelastoma of tricuspid valve in a pediatric patient

We are reporting a rare case of papillary fibroelastoma of the tricuspid valve in an 8-year-old child who presented with pulmonary embolism. Echocardiography was instrumental in determining the source of the pulmonary embolism, but not in delineating between tumor and thrombus. Successful surgical resection of the mass was accomplished and good outcome was attained despite the delay in diagnosis and failure of medical management. A high index of suspicion for tumor involving the tricuspid valve is emphasized despite its rarity in children.

Cardiac papillary fibroelastoma presenting as chorea in childhood

A 5-year-old boy presented with acute onset of chorea and dysarthria. During his workup, a heart murmur was noted. Echocardiography revealed multiple mobile masses in the left ventricular outflow tract related to the mitral valve. Brain magnetic resonance imaging and magnetic resonance angiography did not detect any abnormalities. He underwent a subtotal resection of the mass to preserve valvular function. The anatomic pathology was papillary fibroelastoma.
