Conservative treatment with an intra-aortic balloon pump to treat acute myocardial infarction due to spontaneous coronary artery dissection

Abstract Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. Treatment for SCAD includes conservative approaches, percutaneous coronary intervention (PCI), and coronary artery bypass graft surgery. Although the success rate of PCI is low, conservative treatment often leads to a good clinical course. Three patients with SCAD who were conservatively treated with intra-aortic balloon pumping without coronary intervention are presented. All three patients continue to do well.
