Papillary fibroelastoma: clinical and echocardiographic features and initial approach in 54 cases

Abstract

Papillary fibroelastoma (PFE) is a benign cardiac tumor that is currently detected more often due to the technological improvements in echocardiography. To describe the echocardiographic features of PFE and correlate them with the clinical presentation and initial treatment. A prospective analysis of patients with a diagnosis of PFE was conducted between 2000 and 2015. We assessed the clinical history, symptoms at the time of diagnosis, echocardiographic features, and initial treatment. Fifty-four patients with a diagnosis of PFE by echocardiography were included. The incidence was 0.038%. Mean age was 62±16years; 50% were male. Forty-six percent of patients had symptoms at the time of diagnosis, the most frequent of which was transient ischemic accident (TIA). Embolic episodes occurred in 31% of patients, mainly to the brain. PFEs were valvular in 70.4% of cases and multiple in 13%. Mean maximum length was 1.18±0.58cm, and 44% were mobile. PFEs >1.5cm were most often found in the heart valves (56.8% vs 10.8%; P=.045). There was no significant relation between size, mobility, location and number of tumors, and the presence of embolism or symptoms. Most frequent treatment was oral anticoagulation in 48.6%, followed by simple tumor resection in 42.8% of cases. PFE is a small tumor, predominantly valvular and benign, but entails a high incidence of cerebral embolism. The initial approach should be individualized according to clinical manifestations, comorbidities, and the experience of the surgical center.
