Subacute coronary occlusion with dissection of the sinus of Valsalva after percutaneous coronary intervention in the right coronary artery

SummarySubacute coronary occlusion due to dissection of the right coronary sinus of Valsalva after coronary stenting at the proximal portion of the right coronary artery is described. A bail-out procedure was successfully performed by stent deployment at the ostium of the right coronary artery with its proximal edge protruding into the ascending aorta. However, the patient died of multiple organ failure due to worsened renal failure and cardiogenic shock. An autopsy was performed.
