RESUMEN
PURPOSE OF REVIEW: The no-touch technique is an established method to harvest the saphenous vein (NT-SV), which is the most commonly used conduit in coronary artery bypass grafting. Herein, we summarize the foundational evidence, as well as highlight recent innovations and ongoing clinical trials involving NT-SV. RECENT FINDINGS: Through preservation of perivascular tissue for atraumatic handling and omission of manual distension, the NT-SV maintains endothelial nitrous oxide synthase levels and experiences less vascular smooth muscle cell activation, which translates to slower progression of atherosclerosis and less size mismatch of the graft and target vessel. These biomolecular advantages allow NT-SV to provide superior graft patency compared to conventional skeletonized saphenous vein and approximating that of the radial artery. Nonetheless, the clinical benefits of NT-SV for mortality and reduction in major adverse cardiac and cerebrovascular events are insufficiently studied in the long-term. The drawback of NT-SV is the short-term harvest site complications, which may potentially be addressed by the advent of endoscopic no-touch technique. SUMMARY: NT-SV is a promising conduit, and its role will be further clarified in upcoming clinical trials and as follow-up lengthens. However, conduit selection and harvest technique should ultimately be personalized to the individual patient.

BACKGROUND: Screening programs for abdominal aortic aneurysm (AAA) are not available in Canada. We sought to determine the effectiveness and costutility of AAA screening in Ontario. METHODS: We compared one-time ultrasonography-based AAA screening for people aged 65 years to no screening using a fully probabilistic Markov model with a lifetime horizon. We estimated life-years, quality-adjusted life-years (QALYs), AAA-related deaths, number needed to screen to prevent 1 AAA-related death and costs (in Canadian dollars) from the perspective of the Ontario Ministry of Health. We retrieved model inputs from literature, Statistics Canada, and the Ontario Case Costing Initiative. RESULTS: Screening reduced AAA-related deaths by 84.9% among males and 81.0% among females. Compared with no screening, screening resulted in 0.04 (18.96 v. 18.92) additional life-years and 0.04 (14.95 v. 14.91) additional QALYs at an incremental cost of $80 per person among males. Among females, screening resulted in 0.02 (21.25 v. 21.23) additional life-years and 0.01 (16.20 v. 16.19) additional QALYs at an incremental cost of $11 per person. At a willingness-to-pay of $50 000 per year, screening was cost-effective in 84% (males) and 90% (females) of model iterations. Screening was increasingly cost-effective with higher AAA prevalence. INTERPRETATION: Screening for AAA among people aged 65 years in Ontario was associated with fewer AAA-related deaths and favourable cost-effectiveness. To maximize QALY gains per dollar spent and AAA-related deaths prevented, AAA screening programs should be designed to ensure that populations with high prevalence of AAA participate.

Although cardiovascular diseases are the leading cause of morbidity and mortality worldwide, six billion people lack access to safe, timely and affordable cardiac surgical care when needed. The burden of cardiovascular disease and disparities in access to care vary widely based on sociodemographic characteristics, including but not limited to geography, sex, gender, race, ethnicity, indigeneity, socioeconomic status and age. To date, the majority of cardiovascular, global health and global surgical research has lacked intersectionality lenses and methodologies to better understand access to care at the intersection of multiple identities and traditions. As such, global (cardiac) surgical definitions and health system interventions have been rooted in reductionism, focusing, at most, on singular sociodemographic characteristics. In this article, we evaluate barriers in global access to cardiac surgery based on existing intersectionality themes and literature. We further examine intersectionality methodologies to study access to cardiovascular care and cardiac surgery and seek to redefine the definition of 'global cardiac surgery' through an intersectionality lens.

BACKGROUND: Scientific meetings provide much educational value to participants of all career stages. There is a paucity of literature surrounding the costs of attending scientific meetings and how this may affect participation, especially among trainees. The objective of this study is to assess the accessibility of surgical conferences for attendees by analyzing costs related to surgical society membership and conference registration. METHODS: Societal membership and conference registration fee data were collected according to career stage (i.e., student, resident, fellow, and staff) for the fourteen surgical specialties recognized by the American College of Surgeons (ACS). Fees for participants from low- and middle-income countries (LMICs) and for virtual-only attendance options were also collected when available. RESULTS: Overall, we included data from 46 surgical societies (32 North American, 14 European or global). The median conference fees for students in the member and non-member categories were 191.55 USD (IQR 42.22-320.99) and 452.40 USD (IQR 294.06-555.00), respectively, representing a 136.2% price increase if not a member. Median conference fees for residents, fellows, and staff in the member category were 65.5%, 66.9%, and 230.9% greater than that for students, respectively. Median prices for residents, fellows, and staff in the non-member category were 49.9%, 54.9%, and 49.9% greater than that for member trainees of the same category, respectively. CONCLUSIONS: Our results highlight the substantial costs associated with attending surgical conferences, especially for trainees, representing a significant barrier to already financially burdened trainees, especially those from LMICs, smaller institutions, or less well-off backgrounds.

BACKGROUND: Global data on cardiac surgery centers are outdated and survey-based. In 1995, there were 0.7 centers per million population, ranging from one per 120,000 in North America to one per 33 million in sub-Saharan Africa. This study analyzes the contemporary distribution of cardiac surgery centers and proposes targets relative to countries' cardiovascular disease (CVD) burdens. METHODS: Medical databases, gray literature, and governmental reports were used to identify the most recent post-2010 data that describe the number of centers performing cardiac surgery in each nation. The 2019 Institute for Health Metrics and Evaluation Global Burden of Disease Results Tool provided national CVD burdens. One-third of the CVD burden was assumed to be surgical. Center targets were proposed as the average or half of the average of centers per million surgical CVD patients in high-income countries. RESULTS: 5,111 cardiac surgery centers were identified across 230 nations and territories with available data, equaling 0.73 centers per million population. The median (interquartile range) number of centers ranged from 0 (0-0.06) per million in low-income countries to 0.75 (0-1.44) in high-income countries. Targets were 612.2 (optimistic) or 306.1 (conservative) centers per million surgical CVD incidence. In 2019, low-income, lower-middle-income, and upper-middle-income countries possessed 34.8, 149.0, and 271.9 centers per million surgical CVD incidence. CONCLUSION: Little progress has been made to increase cardiac surgery centers per population despite growing CVD burdens. Today's global cardiac surgical capacity remains insufficient, disproportionately affecting the world's poorest regions.
RESUMEN
PURPOSE OF REVIEW: Coronary artery disease (CAD) is responsible for >50% of heart failures cases. Patients with ischemic left ventricular systolic dysfunction (iLVSD) are known to have poorer outcomes after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) compared to patients with a normal ejection fraction. Nevertheless, <1% of patients in coronary revascularization trials to date had iLVSD. The purpose of this review is to describe coronary revascularization modalities in patients with iLVSD and highlight the need for randomized controlled trial evidence comparing these treatments in this patient population. RECENT FINDINGS: Network meta-analytic findings of observational studies suggest that PCI is associated with higher rates of mortality, cardiac death, myocardial infarction, and repeat revascularization but not stroke compared to CABG in iLVSD. In recent years, outcomes for patients undergoing PCI have improved as a result of advances in technologies and techniques. SUMMARY: The optimal coronary revascularization modality in patients with iLVSD remains unknown. In observational studies, CABG appears superior to PCI; however, direct randomized evidence is absent and developments in PCI techniques have improved post-PCI outcomes in recent years. The Surgical Treatment for Ischemic Heart Failure 3.0 consortium of trials will seek to address the clinical equipoise in coronary revascularization in patients with iLVSD.

PURPOSE OF REVIEW: Decentralized, inconsistent healthcare delivery results in variable outcomes and wastes nearly one trillion dollars annually in the United States (US). Congenital heart surgery (CHS) is not immune due to high, variable costs and inconsistent outcomes across hospitals. Many European countries and Canada have addressed these issues by regionalizing CHS. Centralizing resources lowers costs, reduces in-hospital mortality and improves long-term survival. Although the impact on travel distance for patients is limited, the effect on healthcare disparities requires study. This review summarizes current data and integrates these into paths to regionalization through health policy, research, and academic collaboration. RECENT FINDINGS: There are too many CHS programs in the US with unnecessarily high densities of centers in certain regions. This distribution lowers center and surgeon case volumes, creates redundancy, and increases variation in costs and outcomes. Simultaneously, adhering to suboptimal allocation impedes the understanding of optimal regionalization models to optimize congenital cardiac care delivery. SUMMARY: CHS regionalization models developed for the US increase surgeon and center volume, decrease healthcare spending, and improve patient outcomes without substantially increasing travel distance. Regionalization in countries with few or no existing CHS programs is yet to be explored, but may be associated with more efficient spending and procedural complexity expansion.

Poor glycemic control, regardless of patients' diabetic status, is associated with worse outcomes after coronary artery bypass grafting. As a result, in the perioperative and postoperative setting, the use of insulin is recommended to maintain glucose levels below 180 mg/dl (10.0 mmol/L). However, challenges exist and errors may occur that can prohibit adequate glucose management. In this commentary, we highlight a real-world example of an educational intervention to empower health workers in managing patients' glucose levels after coronary artery bypass grafting in order to improve postoperative outcomes. We discuss the current evidence and guidelines on peri- and postoperative glycemic control for patients undergoing cardiac surgery and present further quality improvement opportunities that may be introduced.

BACKGROUND: This study aimed to evaluate recent trends in utilization, reimbursement, and charges for reconstructive plastic surgery procedures billed to Medicare. METHODS: We queried the Physician/Supplier Procedure Summary from the Centers for Medicare and Medicaid Services for procedures billed by plastic surgeons to Medicare Part B between 2010 and 2019. We collected service counts, charges, and reimbursements. We adjusted utilization by Medicare enrollment and adjusted monetary values for inflation. We calculated the weighted mean charge and reimbursement, which were used to calculate the reimbursement-to-charge ratio (RCR). We examined trends over time by calculating differences and performing correlation analyses of utilization, charges, reimbursement, and RCR for all procedures and for different procedural categories. RESULTS: From 2010 to 2019, the overall enrollment-adjusted utilization for 912 reconstructive procedures decreased by 6.6% (r2 = 0.46). Utilization increased in certain procedural categories such as skin debridement (+36.9%, r2 = 0.48) and procedures of the breast (+114.9%, r2 = 0.48). Charges increased by 32.9% (r2 = 0.99), reimbursement decreased by 5.3% (r2 = 0.84), and RCR decreased by 28.7% (r2 = 0.99). Skin replacement/flaps/grafts procedures underwent the greatest relative decrease in reimbursement (-26.8%, r2 = 0.87). Reimbursement-to-charge ratio decreased for all procedural categories except for procedures of the auditory system. CONCLUSIONS: In the past decade, Medicare utilization and reimbursement for reconstructive plastic surgery procedures decreased, whereas charges increased. This resulted in decreasing reimbursement relative to charged amounts. These findings raise concerns regarding the economic viability of providing plastic surgery services to an aging population and may impact patients' ability to access affordable plastic surgical care.

SummaryGlobal surgery has seen exponential growth over the past few years, and Canadian trainees' interest in the field has followed. Global surgery is defined by a commitment to health equity and community partnership. Engagement with its core principles is relevant for all Canadian surgical trainees and offers a perspective into inequities in surgical access and outcomes for patients and communities, both locally and globally. Several opportunities in academic global surgery for trainees have emerged in Canada, but appear to be underutilized. This article highlights existing Canadian global surgery initiatives, including formal postgraduate curricula, research and policy collaborations, trainee networks, advocacy projects, dedicated fellowships, and conferences. We identify areas in which institutions and departments of surgery can better support trainees in exploring each of these categories during training. Canadian trainees' exposure to global surgery can nurture their roles as future health advocates, communicators, and leaders locally and beyond.

PURPOSE OF REVIEW: Rheumatic heart disease (RHD) affects over 30 million people worldwide. Substantial variation exists in the surgical treatment of patients with RHD. Here, we aim to review the surgical techniques to treat RHD with a focus on rheumatic mitral valve (MV) repair. We introduce novel educational paradigms to embrace repair-oriented techniques in cardiac centers. RECENT FINDINGS: Due to the low prevalence of RHD in high-income countries, limited expertise in MV surgery for RHD, technical complexity of MV repair for RHD and concerns about durability, most surgeons elect for MV replacement. However, in some series, MV repair is associated with improved outcomes, fewer reinterventions, and avoidance of anticoagulation-related complications. In low- and middle-income countries, the RHD burden is large and MV repair is more commonly performed due to high rates of loss-to-follow-up and barriers associated with anticoagulation, international normalized ratio monitoring, and risk of reintervention. SUMMARY: Increased consideration for MV repair in the setting of RHD may be warranted, particularly in low- and middle-income countries. We suggest some avenues for increased exposure and training in rheumatic valve surgery through international bilateral partnership models in endemic regions, visiting surgeons from endemic regions, simulation training, and courses by professional societies.

BACKGROUND: There are substantial racial and socioeconomic disparities underlying endovascular abdominal aortic aneurysm repair (EVAR) in the United States. To date, race-based variations in reinterventions following elective EVAR have not been studied. Here, we aim to examine racial disparities associated with reinterventions following elective EVAR in a real-world cohort. MATERIALS AND METHODS: We used the Vascular Quality Initiative EVAR dataset to identify all patients undergoing elective EVAR between January 2009 and December 2018 in the United States. We compared the association of race with reinterventions after EVAR and all-cause mortality using Welch two-sample t-tests, multivariate logistic regression, and Cox proportional hazards analyses adjusting for baseline differences between groups. RESULTS: At median follow-up of 1.1 ± 1.1 y (1.3 ± 1.4 y Black, 1.1 ± 1.1 y White; P = 0.02), a total of 1,164 of 42,481 patients (2.7%) underwent reintervention after elective EVAR, including 2.7% (n = 1,096) White versus 3.2% (n = 68) Black (P = 0.21). Black patients requiring reintervention were more frequently female, more frequently current or former smokers, and less frequently insured by Medicare/Medicaid (P < 0.05). After adjusting for baseline differences, the risk of reintervention after elective EVAR was significantly lower for Black versus White patients (HR 0.74, 95% CI 0.55-0.99; P = 0.04). All-cause mortality was comparable between groups (HR 0.81, 95% CI 0.33-2.00, P = 0.65). CONCLUSIONS: There are significant differences between Black and White patients in the risk of reintervention after elective EVAR in the United States. The etiology of this difference deserves investigation.

BACKGROUND: In addition to systemic gender disparities, women in surgery encounter interpersonal microaggressions. The objective of this study is to describe the most common forms of microaggressions reported by women in surgery. METHODS: We conducted a scoping review using PubMed/MEDLINE, Ovid, and Web of Science to describe the international, indexed English-language literature on gender-based microaggressions experienced by female surgeons, surgical trainees, and medical students in surgery. After screening by title, abstract, and full-text, 37 articles were retained for data extraction and analysis. Microaggressions were analyzed using the Sexist Microaggression Experience and Stress Scale (MESS) framework and stratified by country of origin. RESULTS: Gender-based microaggression publications most commonly originated from the United States (n = 27 articles), Canada (n = 3), and India (n = 2). Gender-based microaggressions were classified into environmental invalidations (n = 20), being treated like a second-class citizen (n = 18), assumptions of traditional gender roles (n = 12), sexual objectification (n = 11), assumptions of inferiority (n = 10), being forced to leave gender at the door (n = 8), and experiencing sexist language (n = 6). Additionally, attendings were more frequently reported to experience microaggressions than surgical trainees and medical students, but more articles reported data on attendings (n = 16) than surgical trainees (n = 10) or students (n = 4). CONCLUSION: While recent advancements have opened the field of surgery to women, there is still a lack of female representation, and persistent microaggressions may perpetuate this gender disparity. Addressing microaggressions against female surgeons is essential to achieving gender equity in surgical practice.

Cryopreserved pulmonary homografts (PH) are the current gold standard for right ventricular outflow tract (RVOT) reconstruction in the Ross procedure. Unfortunately, their use is limited by a relatively scarce availability and high cost. Porcine stentless xenografts (SX) such as the Medtronic Freestyle SX are increasingly being used, although it is unclear whether the hemodynamic performance and the long-term durability are satisfactory. The present systematic review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement. The pooled treatment effects were calculated using a weighted DerSimonian-Laird random-effects model. We also evaluated the effect of time after RVOT reconstruction on valve gradients using meta-regression. Six studies with a total of 156 patients met the inclusion criteria. The pooled estimates for the pooled follow-up of 37 months were: 1.3% operative mortality, 94.8% overall survival, 7.5% structural valve deterioration, 5.2% reintervention, 73.3% asymptomatic, and 1.5% moderate or severe pulmonary insufficiency. Peak valve gradients were significantly correlated with time after RVOT, increasing during follow-up. Three studies compared PH with SX, one concluded that the SX is an acceptable alternative for RVOT reconstruction, whereas two concluded that this valvular substitute had inferior performance. The Freestyle SX can be considered as an alternative to PH, although it might be associated with more reinterventions, higher peak valve pressure gradients, and pulmonary valve dysfunction.

Six billion people worldwide lack access to safe, timely, and affordable cardiac surgical care when needed, despite cardiovascular diseases remaining the world's leading cause of mortality. The large surgical backlog of rheumatic heart disease, stable and high incidence of congenital heart disease, and growing burden of ischemic heart disease around the world calls for urgent scaling of cardiovascular services beyond mere prevention. National Surgical, Obstetric, and Anesthesia Plans are being developed by countries as holistic health systems interventions to increase access to surgical care, but to date, limited to no attention has been given to the inclusion of cardiovascular care.

Cardiovascular diseases are the leading cause of mortality worldwide, responsible for nearly 18 million deaths each year. More than 80% of these take place in low- and middle-income countries (LMICs), where access to cardiac surgical services is scarce. Approximately 93% of the LMIC population, or six billion people worldwide, are estimated to lack access to safe, timely, and affordable cardiac surgical care as a result of workforce, infrastructure, financial, and quality barriers. Various models have been proposed and attempted to establish cardiac surgery centers in LMICs; however, only some have been successful in achieving sustainable local services. Here, we describe the workforce, infrastructure, financial, and political needs and considerations from a health systems perspective to establish a cardiac surgery center.

Coronavirus disease 2019 has, in the span of weeks, immobilized entire countries and mobilized leading institutions worldwide in a race towards treatments and preventions. Although several solutions such as telemedicine and online education platforms have been implemented to reduce human contact and further transmission, countries need to favour collectivism both within and beyond their borders. Inspired by experiences of previous outbreaks such as SARS in 2003 and Ebola in 2014-2015, global solidarity is a must in order to prevent further morbidity and mortality. Examples in leadership and collaborations ranging from research funds from the Bill and Melinda Gates Foundation to mask donations by the Jack Ma Foundation should be celebrated as examples to follow. Open communication and transparency will be crucial in monitoring the evolution of the disease in the global effort of flattening the curve. This crisis will challenge the integrity and fuel innovation of health systems worldwide, whilst posing a new quality chasm that warrants increased recognition.

Rheumatic heart disease (RHD) remains a neglected disease of poverty. While nearly eradicated in high-income countries due to timely detection and treatment of acute rheumatic fever, RHD remains highly prevalent in low- and middle-income countries (LMICs) and among indigenous and disenfranchised populations in high-income countries. As a result, over 30 million people in the world have RHD, of which approximately 300,000 die each year despite this being a preventable and treatable disease. In LMICs, such as in Latin America, sub-Saharan Africa, and Southeast Asia, access to cardiac surgical care for RHD remains limited, impacting countries' population health and resulting economic growth. Humanitarian missions play a role in this context but can only make a difference in the long term if they succeed in training and establishing autonomous local surgical teams. This is particularly difficult because these populations are typically young and largely noncompliant to therapy, especially anticoagulation required by mechanical valve prostheses, while bioprostheses have unacceptably high degeneration rates, and valve repair requires considerable experience. Devoted and sustained leadership and local government and public health cooperation and support with the clinical medical and surgical sectors are absolutely essential. In this review, we describe historical developments in the global response to RHD with a focus on regional, international, and political commitments to address the global burden of RHD. We discuss the surgical and clinical considerations to properly manage surgical RHD patients and describe the logistical needs to strengthen cardiac centers caring for RHD patients worldwide.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has been a worldwide challenge, and efforts to "flatten the curve," including restrictions imposed by policymakers and medical societies, have forced a reduction in the number of procedures performed in the Brazilian Health Care System. The aim of this study is to evaluate the outcomes of coronary artery bypass graft (CABG) from 2008 to 2020 in the SUS and to assess the impacts of the COVID-19 pandemic in the number of procedures and death rate of CABG performed in 2020 through the database DATASUS. METHODS: This study is based on publicly available material obtained from DATASUS, the Brazilian Ministry of Health's data processing system, on numbers of surgical procedures and death rates. Only isolated CABG procedures were included in our study. We used the TabNet software from the DATASUS website to generate reports. RESULTS: We identified 281,760 CABG procedures performed from January 2008 to December 2020. The average number of procedures until the end of 2019 was of 22,104. During 2020 there was a 25% reduction CABG procedures, to 16,501. There was an increase in the national death rate caused by a statistical significant increase in death rates in Brazil's Southeast and Central-west regions. CONCLUSION: The COVID-19 pandemic remains a global challenge for Brazil's health care system. During the year of 2020 there was a reduction in access to CABG related to an increase in the number of COVID-19 cases. There was also an increase in the national CABG death rate.

BACKGROUND: Brazil is an upper middle-income country in South America with the world's sixth largest population. Despite great advances in health-care services and cardiac surgical care in both its public and private health systems, little is known on the volume, outcomes, and trends of coronary artery bypass grafting (CABG) in Brazil's public health system. OBJECTIVE: The aim of this study was to evaluate the outcome of CABG on the public health system from January 2008 to December 2017 through the database DATASUS. METHODS: This study is based on publicly available material obtained from DATASUS, the Brazilian Ministry of Health's data processing system, on numbers of surgical procedures, death rates, length of stay, and costs. Only isolated CABG procedures were included in our study. We used the TabNet software from the DATASUS website to generate reports. The χ2 test was used to compare death rates. A p < .05 was considered statistically significant. RESULTS: We identified 226,697 CABG procedures performed from January 2008 to December 2017. The overall in-hospital mortality over the 10-year period was 5.7%. We observed statistically significant differences in death rates between the five Brazilian macro-regions. Death rates by state ranged from 2.6% to 13.1%. The national average mortality rate remained stable over the course of time. CONCLUSION: Over 10 years, a high volume of CABG was performed in the Brazilian Public Health System, with significant differences in mortality, number of procedures, and distribution of surgeries by region. Future databases involving all centers that perform CABG and carry out risk-adjusted analysis will help improve Brazilian results and enable policymakers to adopt appropriate health-care policies for greater transparency and accountability.
