The non-tuberculous mycobacteria (NTM) Mycobacterium wolinskyi caused bacteraemia and massive colonization of an aortic prosthesis in a patient 16 days after cardiac surgery, necessitating repeat surgery and targeted antimicrobial chemotherapy. The infection control team investigated the source and conditions of infection. Peri-operative management of the patient complied with recommendations. The environmental investigation showed that although M. wolinskyi was not recovered, diverse NTM species were present in water from point-of-use taps and heater-cooler units for extracorporeal circulation. This case and increasing evidence of emerging NTM infections in cardiac surgery led to the implementation of infection control procedures in cardiac surgery wards.
非结核分枝杆菌（NTM）沃林斯基分枝杆菌在一名患者心脏手术后16天引起菌血症，并在主动脉假体大量定植，需要再次手术和针对性抗菌化疗。感染控制团队对感染源和感染条件进行了调查。患者围手术期管理符合建议。环境调查显示，虽然未检出沃林斯基分枝杆菌，但在体外循环使用点水龙头和加热器-冷却器单元的水中存在多种NTM菌种。该病例以及心脏手术中NTM感染不断增加的证据导致在心脏手术病房实施感染控制程序。
