{Abstract}: <B>UNASSIGNED: </B>Atypical myxoma has been reported in various locations in the heart, however, myxoma involving the pulmonary valve is rare. Here we present a case of pulmonic valve myxoma which was resected via a percutaneous approach.<BR><B>UNASSIGNED: </B>A 66-year-old female with known metastatic adenocarcinoma of the lung, and chronic obstructive pulmonary disease presented with acute onset shortness of breath for two days. The patient experienced respiratory arrest en-route to the hospital and required intubation. Computed tomography angiography (CTA) of the chest revealed a new 1.4 × 1.6 cm intracardiac mass along the pulmonary valve. Further evaluation with cardiac magnetic resonance imaging revealed it to be a large vascular tumor on the ventricular side of the pulmonary valve, attached with a narrow stalk. Due to high surgical risk, the patient underwent transesophageal echocardiographic guided percutaneous removal of the mass. Pathology confirmed the mass to be a myxoma.<BR><B>UNASSIGNED: </B>Atypical myxoma should be considered in the differential diagnosis of valvular masses. Percutaneous resection of valvular masses may be feasible in high-risk surgical patients.<BR><B>CONCLUSIONS: </B>Pulmonary valve myxoma is a rare condition and the literature on the characteristics and treatment options for pulmonary valve myxoma is limited.Our patient was treated with a minimally invasive treatment approach: removal of a tumor with intra operative transesophageal echocardiographic guidance using AngioVac and Flow Triever catheters.Percutaneous resection of valvular masses may be feasible in high surgical risk patients.
