Overview
Papillary fibroelastoma (PFE) is a rare, benign endocardial tumor with uncertain origins, potentially arising as a reactive lesion or true neoplasm. It is occasionally associated with prior cardiac interventions such as surgery or thoracic irradiation 1.Diagnosis
Clinical Presentation: Often asymptomatic but can present with embolic events, valvular dysfunction, or heart murmurs 1.
Echocardiography: Essential for diagnosis, often revealing multiple tumors 1.
Pathological Confirmation: Required for definitive diagnosis, often showing multiple lesions 1.
Correlation with Previous Events: Presence near sites of previous cardiac surgery or radiation therapy 1.Management
Surgical Excision: First-line treatment for symptomatic or large lesions to prevent complications like embolism 1.
Anticoagulation: Considered preoperatively and postoperatively to reduce embolic risk, specific drug classes not detailed 1.
Follow-Up: Regular echocardiographic monitoring recommended post-surgery to detect recurrence or new lesions 1.Special Populations
Postoperative Patients: Higher incidence noted in patients with prior cardiac surgery, tumors often located near surgical sites 1.
Radiation Therapy Recipients: Increased risk of PFE development post-thoracic irradiation 1.Key Recommendations
Surgical excision is recommended for symptomatic papillary fibroelastomas or those posing hemodynamic risk (Evidence: Moderate 1).
Echocardiography should be utilized for both diagnosis and follow-up monitoring (Evidence: Moderate 1).
Consider perioperative anticoagulation to mitigate embolic risk (Evidence: Weak 1).References
