Background:
Papillary fibroelastoma (PFE) is the most common benign cardiac tumor. Because PFEs have the potential to embolize, they typically are surgically excised. Prior studies have suggested that postoperative recurrence of PFE is rare or does not occur.
Objectives:
To determine the rate at which PFEs recurred after surgical removal and to identify any risk factors associated with recurrence.
Methods:
Patients with pathologically proven PFE were retrospectively identified from a single center. Patients were included in the study if they had an echocardiographic examination at least 1 year after surgery. Echocardiographic images obtained intraoperatively (after excision) and at dismissal were compared with those of the most recent examination to assess the possibility of PFE recurrence.
Results:
Ninety eight patients were identified. The mean (SD) duration of follow-up was 5.4 (3.7) years (range, 1-17 years). Twelve patients (12.2%) had echocardiographically proven PFE recurrence. Three patients had the recurrent lesion surgically re-excised, and pathologic analysis showed that 2 were recurrent PFEs and 1 was a Lambl excrescence. Clinical presentation of stroke or TIA was more common for the recurrence patients (for the first PFE) than for the nonrecurrence patients (83% vs 26%;

Conclusions:
Contrary to published data, PFEs do recur after surgical excision. This emphasizes the importance of postoperative follow-up with transesophageal echocardiography for identifying recurrent masses.
