Poster Abstract
The left atrial ridge or “coumadin ridge” is a cardiac anatomic structure located between the left pulmonary vein and the orfice of the left atrial appendage. Historically, patients were misdiagnosed with intra-atrial thrombus and were incorrectly placed on anticoagulation with warfarin, ultimately acquiring the name of the “coumadin ridge”. Fortunately this anatomical variant is now more commonly recognized, however when improperly identified can lead to unnecessary testing, cost, diagnosis anxiety, and inappropriate treatment for the patient. This purpose of this case is to bring awareness to this common clinical dilemma in an attempt to reduce ambiguity and unnecessary workups surrounding this anatomical variant.
