14,17 The tumors set out from the endocardium,13 are attached to the argue by a ill-considered broad-based attachment called a shuck, and swing freely inside the cardiac chamber.6,12 The freely despicable tumor may consequently intermittently block the mitral valve obstructing blood go (this mimics mitral stenosis).6,10 When the patients stands up, gravity can overly pull the myxoma into the opening of the mitral valve blocking blood range into the ventricle.6 Mitral regurgitation may occur if the tumor prolapses through and through the valve and prevents...
