RESUMO
INTRODUCTION: The Charlson Comorbidity Index (CCI) is widely utilized for risk stratification by providers, payors, and administrative database researchers for non-cardiac surgical patients. CCI scores have not been validated in cardiac surgical patients. We hypothesize that the CCI will predict mid-term mortality and re-admissions, but performance may be different than purpose-built cardiac surgery risk calculators. METHODS: Patients undergoing isolated CABG between 2011 and 2017 were reviewed. Age-adjusted CCI scores were calculated based on clinical status at a time of index operation using prospectively captured data from institutional databases. Primary endpoint was 5-year mortality and 1-year re-admissions. The CCI, STS predicted mortality, and ASCERT 5-year mortality scores were compared in a sub-cohort of 500 patients. Patients underwent analysis using Cox Proportional Hazard ratios, Kaplan-Meier analysis, and ROC comparisons. RESULTS: Average CCI score for the overall population (n = 6064) was 3.40 ± 1.75. Kaplan-Meier analysis revealed significant difference in mortality stratified by CCI. Hazard ratio for 5-year mortality increased with each interval increase in CCI score value (HR 1.38 [1.33-1.43], P < 0.001), as did the risk of 1-year re-admission (HR 1.19 [1.15-1.22], P < 0.001). ROC curves for CCI, STS mortality, and ASCERT 5-year mortality risk demonstrate that all three scores are predictive at 5 y, but the ASCERT score performs best (ROC 0.76 versus 0.69, P = 0.004). CONCLUSIONS: The CCI can serve as a useful mid-term risk stratification tool in patients undergoing CABG when variables for the purpose-built STS and ASCERT scores are unavailable. However, the ASCERT score performs better at 5-year mortality calculation.

INTRODUCTION: Bridge to transplantation (BTT) with a SynCardia Total Artificial Heart (TAH) has been gaining momentum as a therapy for patients with biventricular heart failure. Recent transplant waitlist and posttransplant outcomes with this strategy have not been comprehensively characterized. We reviewed the United Network for Organ Sharing (UNOS) database to examine BTT outcomes for the TAH system since approval. METHODS: Adult patients listed for heart transplantation in the UNOS system between 2004 and 2020 who underwent BTT therapy with a TAH were included in the study. Trends in utilization of TAH compared with other durable mechanical support strategies were examined. The primary outcome was 1-year survival following heart transplantation following BTT with TAH. Secondary outcomes included waitlist deterioration and risk factors for waitlist or posttransplant mortality. RESULTS: During the study 433 total patients underwent TAH implant as BTT therapy; 236 (54.4%) were listed with the TAH, while the remaining patients were upgraded to TAH support while on the waitlist. Waitlist mortality was 7.4%, with 375 patients (86.6%) ultimately being transplanted. Age, cerebrovascular disease, functional status, and ventilator dependence were risk factors for waitlist mortality. One-year survival following successful BTT was 80%. Risk factors for mortality following BTT included age, body mass index, and underlying diagnosis. CONCLUSIONS: Patients undergoing BTT with TAH demonstrate acceptable waitlist survival and good 1-year survival. While utilization initially increased as a BTT therapy, there has been a plateau in relative utilization. Individual patient and transplantation center factors deserve further investigation to determine the ideal population for this therapy.

BACKGROUND: The introduction of integrated thoracic surgery residency programs has led to increased recruitment efforts of medical students to pursue a career in cardiac surgery. With little representation of cardiac surgery in medical school curriculum, we assessed a cardiac surgery mini-elective's efficacy in improving perceived knowledge among medical students. METHODS: Preclinical medical students were offered the opportunity to participate in a cardiac surgery mini-elective, which consisted of five 2-hour sessions. These sessions consisted of didactic and simulation components and covered topics including cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenation (ECMO), aortic disease, aortic valve replacement (AVR), transplant and left ventricular assist devices (LVAD), and coronary artery bypass grafting (CABG). Students completed pre- and post-session surveys describing their perceived knowledge in these topics. RESULTS: Overall, 22 students completed at least one session of the mini-elective. Fourteen (73.7%) of the students were male. Fifteen (68.2%) students completed at least three out of five sessions. The post-session survey responses showed significantly higher perceived knowledge compared with pre-session responses for all survey prompts of all five sessions. The CPB/ECMO and aortic disease sessions showed the greatest increase in post-session familiarity and perceived knowledge after the session (P < 0.001) compared with the CABG, AVR, and transplant/LVAD sessions (P < 0.05). CONCLUSIONS: Beyond developing interest in cardiac surgery, these data indicate that a well-planned didactic and surgical simulation program may build confidence in students' knowledge of various cardiac surgical topics. Further studies will need to address how this increase in perceived ability lasts over time and impacts career selection.

Background and Objectives: Post-infarct ventricular septal rupture (PIVSR) continues to have significant morbidity and mortality, despite decreased prevalence. Impella and venoarterial extracorporeal membranous oxygenation (VA-ECMO) have been proposed as strategies to correct hemodynamic derangements and bridge patients to delayed operative repair when success rates are higher. This review places VA-ECMO and Impella support strategies in the context of bridging patients to successful PIVSR repair, with an additional case report of successful bridging with the Impella device. Materials and Methods: We report a case of PIVSR repair utilizing 14 days of Impella support. We additionally conducted a systematic review of contemporary literature to describe the application of VA-ECMO and Impella devices in the pre-operative period prior to surgical PIVSR correction. Expert commentary on the advantages and disadvantages of each of these techniques is provided. Results: We identified 19 studies with 72 patients undergoing VA-ECMO as a bridge to PIVSR repair and 6 studies with 11 patients utilizing an Impella device as a bridge to PIVSR repair. Overall, outcomes in both groups were better than expected from patients who were historically managed with medicine and balloon pump therapy, however there was a significant heterogeneity between studies. Impella provided for excellent left ventricular unloading, but did result in some concerns for reversal of shunting. VA-ECMO resulted in improved end-organ perfusion, but carried increased risks of device-related complications and requirement for additional ventricular unloading. Conclusions: Patients presenting with PIVSR in cardiogenic shock requiring a MCS bridge to definitive surgical repair continue to pose a challenge to the multidisciplinary cardiovascular team as the diverse presentation and management issues require individualized care plans. Both VA-ECMO and the Impella family of devices play a role in the contemporary management of PIVSR and offer distinct advantages and disadvantages depending on the clinical scenario. The limited case numbers reported demonstrate feasibility, safety, and recommendations for optimal management.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) has altered how the current generation of thoracic surgery residents are being trained. The aim of this survey was to determine how thoracic surgery program directors (PDs) are adapting to educating residents during the COVID-19 pandemic. METHODS: Thoracic surgery PDs of integrated, traditional (2 or 3 year), and combined 4 + 3 general/thoracic surgery training programs in the United States were surveyed between 17th April and 1st May 2020 during the peak of the COVID-19 pandemic in much of the United States. The 15-question electronic survey queried program status, changes to the baseline surgical practice, changes to didactic education, deployment/scheduling of residents, and effect of the pandemic on case logs and preparedness for resident graduation. RESULTS: All 23 institutions responding had ceased elective procedures, and most had switched to telemedicine clinic visits. Online virtual didactic sessions were implemented by 91% of programs, with most (69.6%) observing same or increased attendance. PDs reported that 82.7% of residents were on a non-standard schedule, with most being deployed in a 1 to 2 week on, 1 to 2 week off block schedule. Case volumes were affected for both junior and graduating trainees, but a majority of PDs report that graduating residents will graduate on time without perceived negative effect on first career/fellowship position. CONCLUSIONS: The COVID-19 pandemic has radically changed the educational approach of thoracic surgery programs. PDs are adapting educational delivery to optimize training and safety during the pandemic. Long-term effects remain uncertain and require additional study.

SET and MYND domain-containing protein 1 (SMYD1) has been shown to be responsible for the development of fast twitch and cardiac muscle. Mutations in SMYD1 have been shown to be uniformly fatal in laboratory studies, and not previously described in living humans. We describe here the care of an infant suffering from cardiac failure due to an SMYD1 mutation requiring biventricular assist devices as a bridge to successful heart transplantation. The patient is now doing well 2 years post-transplant and represents a known survivor of a suspected uniformly fatal genetic mutation.

BACKGROUND: Integrated cardiothoracic (CT) surgery training programs are an increasingly popular pathway to train CT surgeons. Identifying and engaging medical students early is important to generate interest and ensure highly qualified applicants are aware of opportunities provided by a career in CT surgery. METHODS: An optional CT surgery "mini-elective" was developed for preclinical medical students consisting of five 2-hour sessions covering major procedures in cardiac surgery. Each session had an inital 1 hour lecture immediatly followed by a hands on simulation component. Sessions were taught by CT surgery faculty and residents. A precourse and postcourse survey was administered to identify interest in and awareness of the field of CT surgery. RESULTS: There were 22 students enrolled in the course who provided precourse surveys, while 21 provided postcourse surveys. CT surgery was a career consideration for 95.4% of students who took the mini-elective. nine percent of the students who had either scrubbed or observed a CT case precourse, increased to 33.3% postcourse (P = .11). With regards to mentorship, 23.8% felt they could easily find a mentor in CT surgery precourse, increasing to 66.7% postcourse (P = .01). Eighty-one percent of students reported that the mini-elective significantly increased their CT knowledge over the standard cardiovascular curriculum, and 100% of those completing the course were "extremely satisfied" with the experience. CONCLUSIONS: A CT surgery mini-elective increased awareness and interest in the field among preclinical medical students. Longitudinal exposure and mentorship provided in programs such as this will be key to the continued recruitment of high-quality medical students to the field.

BACKGROUND: This study evaluates outcomes of mitral valve surgery (MVS), replacement (MVR), and repair (MVr), during concomitant aortic valve replacement (AVR). METHODS: Patients undergoing MVS with concomitant AVR between 2011 and 2017 at a single center were reviewed. Patients were stratified into MVR versus MVr with concomitant AVR. Outcomes included early and midterm mortality, hospital re-admissions, re-operations, and complications. Multivariable Cox regression analysis was used for risk-adjustment. RESULTS: Four hundred twenty-four patients underwent MVS with concomitant AVR: 247 (58.3%) MVr and 177 (41.7%) MVR. In unadjusted analysis, there was a non-significant increase in 30-day mortality with MVR, with no differences in 1- and 5-year mortality (30-day: 5.6% vs 10.1%, P = 0.081; 1-year: 14% vs 18.2%, P = 0.181; 5-year: 35.1% vs 37.8%, P = 0.232). Freedom from re-admission and mitral reoperation were comparable. Freedom from at least moderate mitral regurgitation at 5 years was 78% in MVr patients. Those undergoing MVR had increased postoperative blood transfusions, acute renal failure, and pleural effusions requiring drainage (P each <0.05). CONCLUSIONS: MVr can be performed during concomitant AVR without an adverse impact on longer-term outcomes, including mortality, re-admissions, and mitral reoperations. The majority of patients have durable repairs at 5 years although durability is less than that reported in isolated MVS.

A supernumerary intrathoracic rib is a very rare congenital thoracic abnormality that is typically a benign incidental finding. However, in rare cases, they may cause pain, pneumothorax, and injury to surrounding viscus. We report a case of a supernumerary intrathoracic rib causing increasing chest pain diagnosed by computed tomography using three-dimensional reconstructions. The patient underwent robotic-assisted video-assisted thoracoscopic resection of the intrathoracic rib located in her left thorax. The rib was resected without complication, and the patient was discharged from the telemetry unit on post-operative day two. Upon discharge, there was complete resolution of her preoperative symptoms.

Coronary artery bypass graft (CABG) surgery has been used for the treatment of coronary artery disease (CAD) for approximately 50 years, and has been performed on millions of people globally. However, little is known about the impact of diet and exercise on long-term outcomes of patients who have undergone CABG surgery. Although clinical practice guidelines on the management of this patient population have been available for approximately 2 decades, evidence regarding secondary prevention behavioral interventions, lifestyle modifications and self-management to slow the progressive decline of CAD, reduce cardiac hospitalizations, and prevent reoperation remains virtually absent from the literature. Diet and exercise are modifiable factors that affect secondary CAD risk. This article reviews the relevant current literature on long-term diet and exercise outcomes in patients who underwent CABG. The limited available literature shows the positive impacts of exercise on psychosocial well-being and physical fitness. Current evidence indicates diet and exercise interventions are effective in the short-term, but effects fade over time. Potential age and sex differences were found across the reviewed studies; however, further research is needed with more rigorous designs to replicate and confirm findings, and to define optimal management regimens and cost-effective prevention strategies.

Many cardiothoracic surgeons have become less involved in the process of developing therapies and diagnostic tools. There is renewed interest in innovation as a discipline among early career cardiothoracic surgeons and trainees. We describe the role and the essential skillsets that cardiothoracic surgeons must be adopt in order to successfully contribute to medical product innovation.
RESUMO
Interest and core training in congenital heart surgery (CHS) has not been characterized among current cardiothoracic surgical trainees. This study aimed to evaluate perceptions, interest, exposure, and experience among current trainees. A 22 question survey was distributed to all cardiothoracic surgical trainees in ACGME-accredited thoracic surgery residencies. Questions included demographics, exposure to CHS during, perceptions of, participation in and quality assessment of CHS training. There were 106 responses (20.1% response rate) of which 31 (29.0%) were female and 87 (81.3%) were cardiothoracic track. While 69 (64.5%) reported having an interest in CHS at some point during training, only 24 (22.4%) were actively pursuing CHS. All but 7 (6.5%) residents reported having easy access to congenital mentorship, with 35 (32.7%) actively participating in CHS research. Three months was the median duration of congenital rotations. Residents reported less operative participation on CHS compared to adult cardiac surgery. Several residents noted the need for earlier exposure and increased technical/operative experience as areas in need of improvement. The most cited primary influences to pursue CHS included: mentorship, breadth of pathology, and technical nature of the specialty. Lack of consistent job availability and length of additional training were reported as negative influences. Cardiothoracic residents report adequate exposure to obtain case requirements and knowledge for board examinations in CHS but highly variable operative involvement. Mentorship and early exposure remain important for those interested in CHS, while additional training time and limited job availability remain hurdles to CHS.

We aimed to investigate whether there are differences in outcome for pediatric patients when extracorporeal life support (ECLS) is initiated on-hours compared with off-hours. DESIGN: Retrospective cohort study. SETTING: Ten-year period (2009-2018) in United States centers, from the Extracorporeal Life Support Organization registry. PATIENTS: Pediatric (>30 d and <18 yr old) patients undergoing venovenous and venoarterial ECLS. INTERVENTIONS: The primary predictor was on versus off-hours cannulation. On-hours were defined as 0700-1859 from Monday to Friday. Off-hours were defined as 1900-0659 from Monday to Thursday or 1900 Friday to 0659 Monday or any time during a United States national holiday. The primary outcome was inhospital mortality. The secondary outcomes were complications related to ECLS and length of hospital stay. MEASUREMENTS AND MAIN RESULTS: In a cohort of 9,400 patients, 4,331 (46.1%) were cannulated on-hours and 5,069 (53.9%) off-hours. In the off-hours group, 2,220/5,069 patients died (44.0%) versus 1,894/4,331 (44.1%) in the on-hours group (p = 0.93). Hemorrhagic complications were lower in the off-hours group versus the on-hours group (hemorrhagic 18.4% vs 21.0%; p = 0.002). After adjusting for patient complexity and other confounders, there were no differences between the groups in mortality (odds ratio [OR], 0.95; 95% CI, 0.85-1.07; p = 0.41) or any complications (OR, 1.02; 95% CI, 0.89-1.17; p = 0.75). CONCLUSIONS: Survival and complication rates are similar for pediatric patients when ECLS is initiated on-hours compared with off-hours. This finding suggests that, in aggregate, the current pediatric ECLS infrastructure in the United States provides adequate capabilities for the initiation of ECLS across all hours of the day.
RESUMO
BACKGROUND: High risk (HR) factors have been shown to have increased rates of mortality after stage 1 palliation (S1P) for single ventricle physiology. It remains unclear how initial HR status affects longitudinal outcomes after subsequent stage 2 palliation (S2P) and stage 3 palliation (S3P). METHODS: Single ventricle patients undergoing S1P between July 2004 and October 2018 at a single institution were included. Patients having one or more HR factors were considered to have HR status, with all others classified as low risk (LR). Longitudinal survival stratified by risk status was compared after each palliative stage, in addition to readmission and length of stay. Proportional hazards modeling was used to determine risk factors for longitudinal mortality. RESULTS: Of 132 patients presenting during the study for S1P, 57 (43.2%) were classified as HR. Overall 10-year survival was decreased in the HR cohort (P = .001). The HR patients were at significantly increased risk of death during interstage I (P = .01) and interstage II (P = .01), but survival was similar to that of LR patients after S3P (P = .31). Readmission rates after S2P were higher among HR patients (41.9% vs 22.5%, P = .029), but were similar after S3P. Length of stay was increased in the HR cohort after S2P (median 11 vs 9 days, P = .024) but similar to the LR group after S3P. Prematurity was the risk factor most consistently associated with increased mortality after all stages. CONCLUSIONS: A high risk status of patients undergoing S1P portends a higher risk of mortality, length of stay, and readmission after S2P. High-risk patients have survival similar to that of low-risk patients after S3P.

BACKGROUND: While robotic-assisted lung resection has seen a significant rise in adoption, concerns remain regarding initial programmatic outcomes and potential increased costs. We present our initial outcomes and cost analysis since initiation of a robotic lung resection program. METHODS: Patients undergoing either video-assisted thoracoscopic lobectomy or segmentectomy (VATS) or robotic-assisted lobectomy or segmentectomy (RALS) between August of 2014 and January of 2017 underwent retrospective review. Patients underwent 1:1 propensity matching based on preoperative characteristics. Perioperative and 30-day outcomes were compared between groups. Detailed activity-based costing analysis was performed on individual patient encounters taking into effect direct and indirect controllable costs, including robotic operative supplies. RESULTS: There were no differences in 30-day mortality between RALS (n = 74) and VATS (n = 74) groups (0% vs 1.4%; P = 1). RALS patients had a decreased median length of stay (4 days vs 7 days; P < .001) and decreased median chest tube duration (3 days vs 5 days, P < .001). Total direct costs, including direct supply costs, were not significantly different between RALS and VATS ($6621 vs $6483; P = .784). Median total operating costs and total unit support costs, which are closely correlated to length of stay, were lower in the RALS group. Overall median controllable costs were significantly different between RALS and VATS ($16,352 vs $21,154; P = .025). CONCLUSIONS: A potentially cost-advantageous robotic-assisted pulmonary resection program can be initiated within the context of an existing minimally invasive thoracic surgery program while maintaining good clinical outcomes when compared with traditional VATS. Process-of-care changes associated with RALS may account for decreased costs in this setting.

OBJECTIVE: Academic productivity during cardiothoracic surgery residency training is an important program metric, but is highly variable due to multiple factors. This study evaluated the influence of implementing a protocol to increase resident physicians' academic productivity in cardiac surgery. METHODS: A comprehensive protocol for cardiac surgery was implemented at our institution that included active pairing of residents with academically productive faculty, regular research meetings, centralized data storage and analysis with a core team of biostatisticians, a formal peer-review protocol for analytic requests, and project prioritization and feedback. We compared cardiothoracic surgery residents' academic productivity before implementation (July 2015-June 2017) versus after implementation (July 2017-June 2019). Academic productivity was measured by peer-reviewed articles, abstract presentations (oral or poster) at national cardiothoracic surgery meetings, and textbook chapters. RESULTS: Thirty-four resident physicians (from traditional and integrated programs) trained at our institution during the study. A total of 122 peer-reviewed articles were produced over the course of the study: 74 (60.7%) cardiac- and 48 (39.3%) thoracic-focused. The number of cardiac-focused resident-produced articles increased from 10 preimplementation to 64 postimplementation (0.61 vs 2.03 articles per resident; P < .01). Abstract oral or poster presentations also increased, from 11 to 40 (0.61 vs 1.33 abstracts per resident; P = .01). Textbook chapters increased from 4 to 15 following the intervention (0.22 vs 0.5 chapters per resident; P = .01). CONCLUSIONS: Implementation of a dedicated protocol to facilitate faculty mentoring of resident research and streamline the data access, analysis, and publication process substantially improved cardiothoracic surgery residents' academic productivity.

Objective: The Thoracic Surgery Residents Association (TSRA) is a trainee-led cardiothoracic surgery organization in North America that has published a multitude of educational resources. However, the utilization of these resources remains unknown. Methods: Surveys were constructed, pilot-tested, and emailed to 527 current cardiothoracic trainees (12 questions) and 780 former trainees who graduated between 2012 and 2019 (16 questions). The surveys assessed the utilization of TSRA educational resources in preparing for clinical practice as well as in-training and American Board of Thoracic Surgery (ABTS) certification examinations. Results: A total of 143 (27%) current trainees and 180 (23%) recent graduates responded. A higher proportion of recent graduates compared with current trainees identified as male (84% vs 66%; P = .001) and graduated from 2- or 3-year traditional training programs (81% vs 41%; P < .001), compared with integrated 6-year (8% vs 49%; P < .001) or 4 + 3 (11% vs 10%; P = .82) pathways. Current trainees most commonly used TSRA resources to prepare for the in-training exam (75%) and operations (73%). Recent graduates most commonly used them to prepare for Oral and/or Written Board Exams (92%) and the in-training exam (89%). Among recent graduates who passed the ABTS Oral Board Exam on the first attempt, 82% (97/118) used TSRA resources to prepare, versus only 48% (25/52) of recent graduates who passed after multiple attempts, failed, have not taken the exam, or preferred not to answer (P < .001). Conclusions: Current cardiothoracic trainees and recent graduates have utilized TSRA educational resources extensively, including to prepare for in-training and ABTS Board examinations.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) has had a widespread impact on graduate medical education. This survey aims to assess how general surgery residency programs adapted to the initial wave of the COVID-19 pandemic in the United States (US). MATERIALS AND METHODS: General surgery program directors (PDs) in the US were invited to partake in a 16-question survey between April 17 and May 1, 2020. The survey included questions about basic program information, clinical practice changes, changes to education structure, surgery resident clinical duties, and perceived impact on resident operative experience and future career choices. RESULTS: Forty-eight PDs completed the survey in the designated two-week period. Almost all (44/48, 91.7%) programs changed their didactic education to an online video conference-based format. Thirteen programs (27.1%) decreased the amount/frequency of formal education, and 13 (27.1%) reported canceling didactic education for some period of time. The majority of PDs (26/48, 54.2%) felt these changes had no impact on resident didactic participation, 14 (29.2%) reported an increase in participation, and 8 (16.7%) reported decreased participation. Ten programs (20.8%) redeployed residents to non-surgical services at the time of this survey, 30 (62.5%) have not redeployed residents but plan to if needed, and 8 (16.7%) did not have any plans to redeploy residents. CONCLUSIONS: The outbreak of COVID-19 has required general surgery residency PDs to change numerous aspects of resident education and clinical roles. Future inquiry is needed to assess if these changes lead to appreciable differences in resident preparedness and career selection.
RESUMO
A biohybrid patch without cellular components was implanted over large infarcted areas in severely dilated hearts. Nonpatched animals were assigned to control or losartan therapy. Patch-implanted animals responded with better morphological and functional echocardiographic endpoints, which were more evident in a subgroup of animals with very low pre-treatment ejection fraction (<35%). Patched animals also had smaller infarcts than both nonpatched groups. This simple approach could hold promise for clinical translation and be applied using minimally invasive procedures over the epicardium in a large set of patients to induce better ventricular remodeling, especially among those who are especially frail.
