Multimodality imaging enables accurate tissue characterization and guides timely surgical management of pulmonary valve papillary fibroelastomas that do not regress with anticoagulation.
Multimodality imaging is essential for accurately diagnosing and guiding the surgical management of pulmonary valve papillary fibroelastomas that mimic persistent pulmonary embolism.
Persistent pulmonary artery filling defects that do not regress with anticoagulation should prompt reconsideration of the diagnosis and multimodality imaging to exclude other causes. Integrated use of echocardiography, CT, CMR, and PET/CT enables accurate tissue characterization and guides timely surgical management of PFE.
Tejada et al. (2026) studied this question. Multimodality imaging enables accurate tissue characterization and guides timely surgical management of pulmonary valve papillary fibroelastomas that do not regress with anticoagulation.
