The learning curve of robotic coronary arterial bypass surgery: A report from the STS database.

BACKGROUND: There is limited data to inform minimum case requirements for training in robotically assisted coronary artery bypass grafting (RA-CABG). Current recommendations rely on nonclinical endpoints and expert opinion. OBJECTIVES: To determine the minimum number of RA-CABG procedures required to achieve stable clinical outcomes. METHODS: We included isolated RA-CABG in the Society of Thoracic Surgeons (STS) registry performed between 2014 and 2019 by surgeons without prior RA-CABG experience. Outcomes were approach conversion, reoperation, major morbidity or mortality, and procedural success. Case sequence number was used as a continuous variable in logistic regression with restricted cubic splines with fixed effects. Outcomes were compared between operations performed earlier versus later in case sequences using unadjusted and adjusted metrics. RESULTS: There were 1195 cases performed by 114 surgeons. A visual inflection point occurs by a surgeon's 10th procedure for approach conversion, major morbidity or mortality, and overall procedural success after which outcomes stabilize. There was a significant decrease in the rate of approach conversion (7.7% and 2.5%), reoperation (18.9% and 10.8%), and major morbidity or mortality (21.7% and 12.9%), as well as an increase in the rate of procedural success (72.9% and 85.3%) with increasing experience between groups. In a multivariable logistic regression model, case sequences of >10 were an independent predictor of decreased approach conversion (odds ratio [OR]: 0.27; 95% confidence interval [CI]: 0.09-0.84) and increased rate procedural success (OR: 1.96; 95% CI: 1.00-3.84). CONCLUSIONS: The learning curve for RA-CABG is initially steep, but stable clinical outcomes are achieved after the 10th procedure.

Wisdom From Past Presidents of The Society of Thoracic Surgeons.

The Society of Thoracic Surgeons is a highly impactful professional organization in cardiothoracic surgery and an important network of mentors for trainees. Annually, presidents of The Society of Thoracic Surgeons deliver an address encapsulating their professional experiences, lessons learned, and future vision for the field. We sought to summarize these lessons into salient points for trainees. Transcriptions from 1964 to 2018 were reviewed by residents and expounded into categories of importance for readers. Six overarching themes were identified: (1) leadership, (2) education, (3) clinical excellence and innovation, (4) humanism and professionalism, (5) diversity and inclusion, and (6) the future of cardiothoracic surgery.

Characteristics and Attitudes of Aspiring Cardiothoracic Surgeons: A Survey Study.

BACKGROUND: Although recruiting highly qualified, diverse applicants into cardiothoracic surgery remains a national priority, their characteristics remain unknown. This study aims to describe current and future applicants in cardiothoracic surgery. METHODS: Aspiring cardiothoracic surgeons (students interested in matriculating in a North American training program) were voluntarily enrolled in the study through Twitter and email outreach. A 33-question survey evaluated their backgrounds, research experiences, attitudes, and interests within cardiothoracic surgery. Standard descriptive statistics were used. RESULTS: There were 111 participants, 40 of whom were female (36.0%) and 27 of whom identified as an underrepresented minority (24.3%). Of the total, 63 belonged to an institution with a cardiothoracic surgery training program (56.8%). A total of 91 students envisioned having a mostly operative career (82.0%) and 75 envisioned pursuing educational roles (67.6%). The most popular surgical specialties were heart transplantation (50.5%) and aortic surgery (47.8%). Participants selected having a high-intensity operative environment (81.2%) and an innovative academic environment (58.8%) as the most attractive qualities. Perceived lack of work-life balance (46%) and toxic training or work environment (28%) were the greatest deterrents. Finances during the application process were perceived as a potential barrier by 41 students (36.9%). Approximately 75% of students (83 of 111) had faculty as mentors; 46.8% (56 of 111) thought that cardiothoracic surgery faculty were approachable but had limited time for mentorship. CONCLUSIONS: This survey study characterized a nationally selected pool of aspiring cardiothoracic surgeons using social media. Future studies involving larger and more diverse cohorts are warranted to find areas for improvement in recruitment, retention, and diversity.
