Abstract:
Coumadin ridge is a normal anatomic variant that is occasionally found in the left atrium. It can present as a linear or nodular mass which can undulate with cardiac motion and if particularly prominent, can easily be mistaken for a tumor or thrombus. Careful evaluation and consideration of the common variants discussed in this review can help limit misdiagnosis, as well as unnecessary workup and treatment. We present a case of coumadin ridge that was found on a patient using two-dimensional transthoracic echocardiography.
