A 70‐year‐old man underwent the frozen elephant trunk (FET) procedure with zone 0 debranching following a failed endovascular repair for type B aortic dissection and a stent‐graft deployment in zone 1 for a retrograde type A aortic dissection. Zone 0 deployment is a novel approach that is valuable as a bailout strategy in urgent cases and it can potentially improve the technical feasibility of the FET while minimizing its ischemic complications.

Introduction The state of cognitive flow, colloquially known as being ‘in the zone’, has been linked with enhanced performance, happiness, career satisfaction and decreased burnout. However, the concept has not been adopted strongly in health care training, continuing professional development, or daily practice. A systematic review with a narrative synthesis was undertaken to map the evidence for flow in health care. Methods A search was conducted in MEDLINE, PsycInfo, and EMBASE in July 2019 and updated in October 2020 for manuscripts discussing flow in all health care disciplines. Articles published between 1806 and 13 October 2020 were included. Two authors independently reviewed titles and abstracts (and subsequently full texts where necessary) for inclusion. Disagreements were resolved by consensus. Data were extracted on location, manuscript type, population and context, measures, and key findings. Results A total of 4923 unique abstracts were initially retrieved, and 15 articles were included in the final review. We report on the experience, benefits and strategies to support flow in health care. Flow may benefit providers by enhancing career enjoyment, wellness and performance, while mitigating exhaustion, burnout, and stress. Although research from other domains has focused on supporting flow through individualised training, our results highlight the importance of system and environmental factors. Conclusions Supporting professional and trainee flow in health care requires a holistic approach, including individual training and system‐level interventions.

Background: Lung transplantation is an effective treatment option for end-stage lung diseases. In some cases, these patients may also have underlying cardiac disease which may require surgical intervention before or during transplantation. Concomitant cardiac surgery may often be preferred, as reduced lung function precludes these patients from pre-transplant surgery. Our meta-analysis sought to examine the impact of lung transplantation paired with concomitant cardiac surgery on long-term mortality.Methods: We conducted a systematic review of the MEDLINE, Embase, and Cochrane databases. Our primary outcome was overall mortality. Secondary outcomes included length of stay (LOS) in hospital and serious postoperative complication rates. We used a meta-analytic model to determine the differences in the above outcomes between patients who underwent lung transplantation with or without concomitant cardiac surgery.Results: Out of the 1876 articles screened, 7 met our pre-determined inclusion criteria. Lung transplantation with concomitant cardiac surgery was not associated with increased mortality compared to lung transplantation alone (hazard ratio = 1.02; 95% confidence interval [CI] = 0.80-1.31; I 2 = 0%; p = .99). LOS in hospital was not significantly different between groups (standardized mean difference = 0.32; 95% CI = −0.91 to 1.55). Postoperative complication rates were also reported but not analyzed due to missing data.Conclusions: There was no significant difference in mortality rates in patients undergoing lung transplantation with or without concomitant cardiac surgery at 1, 3, and 5 years. However, postoperative complication rates were higher in the concomitant group. The decision to perform concomitant procedures should be tailored to each patient's clinical condition.
