MYXOMA

Cardiac myxomas be r ar, benign, slow growing primary cardiac tumors demonstrate most commonly in the septum of the left atrium, although they can find in any chamber of the emotional state.1,2,3,4 Myxomas account for about 50% of all benign intercardiac tumors making them the most common.14,15,16,17,18 Approximately 70-85% of myxomas guide in the left atrium and the remainder in the right atrium.1,2,5,7,9,10,11,12,13,14,16,17 very(prenominal) rarely one will occur in any ventricle.1,2,9,12,13,14,16 A very small percentage (10% or less) of myxomas are considered hereditary.1,6,7,9,10,17 Hereditary myxomas typically occur in men in their 20s.1,6 Non-hereditary myxomas most often occur in women between the ages of 30 and 60.6,10,15 Myxomas can appear white, gray, yellow, brown, or green and can plod from 1 cm to 15 cm in size13,16 with the amount size being 5-6 cm.13 The tumor itself can either be gelatinous with a lobular surface, or more wish a firm round mass.7,32 The tumor is quite vascular and may be coated with thrombi.15 About 30-50% of patients experience embolization to the brain, kidneys, eyes, or extremities.4,7,17 The left atrial myxomas often arise from the upper helping of the septum and may prolapse by means of the mitral valve during diastole.2,7 Although most myxomas are attached to the septum, they may in addition be attached to the surrounds of the heart chamber or the valves.



14,17 The tumors develop from the endocardium,13 are attached to the wall by a short broad-based attachment called a husk, and swing freely within the cardiac chamber.6,12 The freely mournful tumor may then intermittently block the mitral valve obstructing blood go (this mimics mitral stenosis).6,10 When the patients stands up, gravity can also pull the myxoma into the opening of the mitral valve blocking blood flow into the ventricle.6 Mitral regurgitation may occur if the tumor prolapses through the valve and prevents...
