Tumor Plop (Left Atrial Myxoma)

Texas Heart Institute Heart Sounds Series - Ein Podcast von Texas Heart Institute at St. Luke's

A large left atrial myxoma produces a diastolic sound that is referred to as a tumor plop. This sound arises from obstruction to ventricular in-flow that occurs as the tumor comes to rest over the mitral annulus. It is the functional equivalent of mitral valve stenosis and may be associated with a low frequency diastolic murmur. Copyright 2011 by the Texas Heart Institute at St. Luke's Episcopal Hospital.
