Left main coronary artery (LMCA) atresia is a quite rare congenital malformation, which may present with various symptoms. Past literatures were sporadic without recent summary of world-wide cases. We hereby report an adult case of LMCA atresia with concomitant mitral regurgitation and also summarize all cases found in published literatures. Case presentation: A 48-year old female presented with sudden dyspnea. Preliminary impression was acute heart failure caused by mitral regurgitation. Preoperative coronary angiography demonstrated that there was no left coronary ostium and multiple collateral vessels arising from right coronary artery. The diagnosis of left main coronary atresia was made and the patient received successful valvuloplasty and coronary artery bypass grafting with left internal mammary artery anastomosed to the left anterior descending (LAD) artery. She recovered well and 3-month follow-up showed the graft was patent. Conclusion: This case highlights the importance of angiography for diagnosis of LMCA and performance of CABG once diagnosed.
