Surgical excision of a rare pulmonic valve papillary fibroelastoma resulted in preserved valve function and an uneventful recovery, highlighting the role of TEE for intraoperative guidance.
Case Report (n=1)
This case highlights the role of TEE in defining pulmonic valve mass morphology and providing real-time intraoperative guidance for the surgical excision of a rare pulmonic valve papillary fibroelastoma.
Abstract Papillary fibroelastomas involving the pulmonic valve are rare and may present incidentally or with nonspecific cardiopulmonary symptoms. We report a 75-year-old woman with an incidentally discovered right ventricular outflow tract mass ultimately identified as a papillary fibroelastoma arising from the ventricular aspect of the left pulmonic valve cusp. Multimodality imaging, including transthoracic and transesophageal echocardiography (TEE) and cardiac magnetic resonance imaging, confirmed a mobile, pedunculated lesion without associated valve dysfunction. The mass was excised on cardiopulmonary bypass through a pulmonary arteriotomy without aortic cross-clamping. Post-resection TEE confirmed preserved pulmonic valve morphology and function. Histopathologic analysis confirmed the lesion to be a papillary fibroelastoma. The patient recovered uneventfully and was discharged home on postoperative day 4. This case underscores the pivotal role of TEE in defining pulmonic valve mass morphology and providing real-time intraoperative guidance.
Mirrakhimov et al. (2026) conducted a case report in Papillary fibroelastoma involving the pulmonic valve (n=1). Surgical excision was evaluated. Surgical excision of a rare pulmonic valve papillary fibroelastoma resulted in preserved valve function and an uneventful recovery, highlighting the role of TEE for intraoperative guidance.
