Recently reported in Europe and United States, disseminated Mycobacterium chimaera infection is a novel clinical entity linked to point contamination of Stockert 3T heater-cooler units used for cardiopulmonary bypass. We present here the first two cases in Canada. ⋯ One patient is currently improving, and the other needed mitral valve repair despite aggressive treatment. Because of the nonspecific mode and timing of presentation, a high index of suspicion is necessary for the diagnosis of M. chimaera infection.

Important Non-Technical Skills in Video-Assisted Thoracoscopic Surgery Lobectomy: Team Perspectives.
Safety in the operating room is dependent on the team's non-technical skills. The importance of non-technical skills appears to be different for minimally invasive surgery as compared with open surgery. The aim of this study was to identify which non-technical skills are perceived by team members to be most important for patient safety, in the setting of video-assisted thoracoscopic surgery (VATS) lobectomy. ⋯ This study identified six non-technical skills that serve as the foundation for shared mental models of the patient, the current situation, and team resources. These findings contribute three important additions to the shared mental model construct: planning and preparation, risk assessment, and leadership. Shared mental models are crucial for patient safety because they enable VATS teams to anticipate problems through adaptive patterns of both implicit and explicit coordination.

Vasoplegic syndrome, defined by hypotension despite normal or increased cardiac output, is associated with high mortality rate after cardiopulmonary bypass. Methylene blue (MB) is reported to ameliorate vasoplegic syndrome through the nitric oxide pathway. We hypothesized that early administration of MB would improve outcomes in patients with vasoplegic syndrome after cardiopulmonary bypass. ⋯ Operative mortality rate is high in patients receiving MB for the treatment of vasoplegia after cardiopulmonary bypass. Early administration of MB improves survival and reduces the risk-adjusted rate of major adverse events in these patients.

Understanding Children's Heart Surgery Data: A Cross-Disciplinary Approach to Codevelop a Website.
Risk-adjusted survival statistics after children's heart surgery are published annually in the United Kingdom. Interpreting these statistics is difficult, and better resources about how to interpret survival data are needed. ⋯ Early and ongoing involvement of users was crucial and considerably changed the content, scope, and look of the website, and the formal psychology experiments provided deeper insight. The website http://childrensheartsurgery.info/ was launched in June 2016 to very positive reviews.
