Coronary artery stent dislodgement and aortic dissection in a patient with a severely calcified lesion in the proximal right coronary artery

Learning objective: During percutaneous coronary intervention (PCI), stent dislodgement and aortic dissection are extremely rare, but life-threatening complications. In this rare case of simultaneous stent dislodgement in the coronary artery and aortic dissection during PCI for a severely calcified lesion in the right coronary artery with shepherd's crook morphology, the situation was successfully rectified by using balloons to retrieve and deploy the stent, as well as by applying an additional stent and minimizing the contrast used to treat aortic dissection.
