Pulmonary Artery Hypertension and Related Complications Associated to Left Atrial Myxoma.

Atrial Myxoma (AM) is a primary benign tumour of the heart that may behave in a not so benign manner causing serious cardiac and systemic complications [1 4]. The global annual incidence of AM is 0.5 per million people and may occur in different locations within the heart cavities but primarily affect the left atrium in 75% of the cases [5 7]. There have been reports of myxoma in the right atrium and in the left or right ventricles [8, 9]. The symptoms may widely differ depending on several factor related to the mass itself. AM tends to differ in shape, size, and texture, and originate from the vicinity of the fossa ovalis in the inter-atrial septum. AM occurs in patients between the ages of 30 and 60 years, but it can be seen at any age [7]. Sometimes, AM is discovered incidentally while investigating nonspecific symptoms on a routine echocardiography. Most AM are isolated, and they present in familial cases in less than 10%.
