The Coumadin Ridge: Why Do We Need To Know About It?

Main Article Content

Lertlak Chaothawee, MD


Coumadin or Warfarin ridge is so named for its band-like structure that originates in the left atrium and is almost always misdiagnosed as a cardiac tumor or a cardiac thrombus. This article will detail the important information of the coumadin ridge and demonstrate its structure and location with the use of Magnetic Resonance Imaging (MRI) .
