title: A case of percutaneous coronary intervention for treatment of iatrogenic chronic total occlusion of the left circumflex artery after mitral valve repair.
abstract: A 55-year-old man had undergone mitral annuloplasty for mitral regurgitation with posterior mitral prolapse 3 years prior. He was examined at our hospital for dyspnea and fatigue. A coronary angiogram revealed iatrogenic chronic total occlusion (CTO) in the left circumflex coronary artery. We performed percutaneous coronary intervention (PCI) and successfully placed an everolimus-eluting stent. An intravascular ultrasound (IVUS) showed an impaired coronary artery at the occlusion site. To our knowledge, this is the first reported successful PCI for iatrogenic CTO after mitral valve repair. IVUS-guided PCI may help prevent complications in unusual CTO cases, such as coronary rupture.
