A 62-year-old woman referred to the cardiology clinic for the evaluation of fatigue and dyspnea for 4 months. She also has loose stools (2–4 per day), palpitations, and non-pitting edema up to her mid-calf. On examination, vital signs are unremarkable, but she appears to be flushed with mild bilateral wheezes can be heard on chest auscultation. Cardiovascular examination reveals a grade 2/6 holosystolic murmur at the left mid-sternal area, which is louder during inspiration. Basic laboratory investigations are unremarkable. Echocardiography reveals moderate to severe right ventricular dilatation with severe right ventricular systolic dysfunction. A CT of the chest and abdomen reveals a solid, non-obstructing 2 cm mass in the small intestine and a solid 1.5 cm mass in the liver. What is the most likely cause of her symptoms?
