Justice Ruth Bader Ginsburg underwent a coronary catheterization procedure this morning at MedStar Heart & Vascular Institute at MedStar Washington Hospital Center to place a stent in her right coronary artery. The coronary blockage was discovered after Justice Ginsburg experienced discomfort during routine exercise last night and was taken to the hospital. She is resting comfortably and is expected to be discharged in the next 48 hours.
