RESUMO
AIM: The "2022 ACC/AHA Guideline for the Diagnosis and Management of Aortic Disease" provides recommendations to guide clinicians in the diagnosis, genetic evaluation and family screening, medical therapy, endovascular and surgical treatment, and long-term surveillance of patients with aortic disease across its multiple clinical presentation subsets (ie, asymptomatic, stable symptomatic, and acute aortic syndromes). METHODS: A comprehensive literature search was conducted from January 2021 to April 2021, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, CINHL Complete, and other selected databases relevant to this guideline. Additional relevant studies, published through June 2022 during the guideline writing process, were also considered by the writing committee, where appropriate. Structure: Recommendations from previously published AHA/ACC guidelines on thoracic aortic disease, peripheral artery disease, and bicuspid aortic valve disease have been updated with new evidence to guide clinicians. In addition, new recommendations addressing comprehensive care for patients with aortic disease have been developed. There is added emphasis on the role of shared decision making, especially in the management of patients with aortic disease both before and during pregnancy. The is also an increased emphasis on the importance of institutional interventional volume and multidisciplinary aortic team expertise in the care of patients with aortic disease.

BACKGROUND: Operative mortality for type A aortic dissection is still 10-20% at centers of excellence. Additionally, 10-20% are not considered as viable candidates for open surgical repair and not offered life-saving emergency surgery. ARISE is a multicenter investigation evaluating the novel GORE® Ascending Stent Graft (ASG; Flagstaff, AZ). OBJECTIVE: The purpose of this study is to assess early feasibility of using these investigational devices to treat ascending aortic dissection. METHODS: This a prospective, multicenter, non-randomized, single-arm study that enrolls patients at high surgical risk with appropriate anatomical requirements based on computed tomography imaging at 7 of 9 US sites. Devices are delivered transfemorally under fluoroscopic guidance. Primary endpoint is all-cause mortality at 30 days. Secondary endpoints include major adverse cardiovascular and cerebrovascular events (MACCE) at 30 days, 6 months, and 12 months. RESULTS: Nineteen patients were enrolled with a mean age of 75.7 years (range 47-91) and 11 (57.9%) were female. Ten (52.6%) had DeBakey type I disease, and the rest were type II. Sixteen (84.2%) of the patients were acute. Patients were treated with safe access, (7/19 (36.8%) percutaneous, 10/19 (52.6%) transfemoral, 2/19 (10.5%) iliac conduit), delivery, and deployment completed in all cases. Median procedure time was 154 mins (range 52-392) and median contrast used was 111 mL (range 75-200). MACCE at 30 days occurred in 5 patients including mortality 3/19 (15.8%), disabling stroke in 1/19 (5.3%), and myocardial infarction in 1/19 (5.3%). CONCLUSION: Results from the ARISE early feasibility study of a specific ascending stent graft device to treat ascending aortic dissection are promising.

PURPOSE: Patients with complicated ascending aortic pathology, including patients with acute type A aortic dissection may be at extreme risk for open repair. Thoracic endovascular aortic repair (TEVAR), infrequently used for the ascending aorta, may be considered an alternative in this setting. We describe early results for emergency and compassionate (E&C) use of a novel endograft, specifically designed for use to treat pathology of the ascending aorta. MATERIALS AND METHODS: This case series evaluated 19 patients (mean age, 68.84±13.12 years; 57.9% female) treated with ascending TEVAR for acute and chronic acute (4), subacute (1), or chronic (1) aortic dissection or pseudoaneurysm (13). Six of the 19 patients (31.5%) were treated under compassionate use and 13 patients (68.4%) were treated under the emergency use exemption. Ten patients (52.6%) received additional devices to extend treatment into the arch and descending aorta. RESULTS: Device delivery was achieved in all patients (100%). Thirty-day mortality and stroke occurred in 3 patients (15.8%) and in 1 patient (5.3%), respectively. In 1 patient (5.3%), with an Unanticipated Adverse Device Event, the aorta ruptured when the endograft eroded into the adventitial portion of dissection site at the posterior aspect of the ascending wall. Devices were explanted in 2 patients (10.5%), 353 and 610 days after the index procedure, respectively. Six patients had endoleaks (31.6%), including type I (n=2, 10.5%), type II endoleaks (n=3, 15.8%), and indeterminate endoleak (n=1, 5.3%). CONCLUSIONS: Delivery and deployment of a novel ascending thoracic stent graft with or without an additional branched arch extension is feasible in patients with complex anatomy and pathology, including acute aortic dissection and pseudoaneurysm. Additional experience with this novel device will further refine the patient population most suitable for endovascular ascending aortic repair for these pathologies. CLINICAL IMPACT: This study describes a novel stent graft specifically designed for treatment of ascending aortic pathology, including acute type A dissection. The patients described in this series constituted a group outside the formal US FDA sponsored clinical trial, and were those accepted as part of an emergency and compassionate use basis.
RESUMO
BACKGROUND: The safety and efficacy of leadless pacemakers (LP) in transcatheter aortic valve implant (TAVI) patients is not well known due to paucity of data. Herein, we compared outcomes between leadless pacemakers to traditional dual chamber pacemakers (DCP) following TAVI. METHODS: A single-center retrospective study was conducted, including a total of 27 patients with LP and 33 patients with DCP after TAVI between November 2013 and May 2021. We compared baseline demographics, pacemaker indications, complication rates, percent pacing, and ejection fractions. RESULTS: Leading indications for pacemaker implant were complete heart block (74% LP, 73% DCP) and high degree atrioventricular block (26% LP, 21% DCP). Twenty-two (82%) LP patients had devices implanted in the right ventricular septal-apex. Three (9%) DCP patients required rehospitalization for pocket related complications. Zero pacemaker-related mortality was observed in both groups. Frequency of ventricular pacing and ejection fraction was similar between LP and DCP groups. CONCLUSION: From this single-center retrospective study, LP implant was feasible following TAVI and was found to have comparable performance to DCPs. LPs may be a reasonable alternative in TAVI patients where single ventricular pacing is indicated. Larger studies are required to validate these findings.

Cardiovascular disease remains the leading cause of morbidity and mortality for women in United States and worldwide. One in 3 women dies from cardiovascular disease, and 45% of women >20 years old have some form of CVD. Historically, women have had higher morbidity and mortality after cardiac surgery. Sex influences pathogenesis, pathophysiology, presentation, postoperative complications, surgical outcomes, and survival. This review summarizes current cardiovascular surgery outcomes as they pertain to women. Specifically, this article seeks to address whether sex disparities in research, surgical referral, and outcomes still exist and to provide strategies to close these gaps. In addition, with the growing population of women of reproductive age with cardiovascular disease and cardiovascular risk factors, indications for cardiac surgery arise in pregnant women. The current review will also address the unique issues associated with this special population.

OBJECTIVE: The aim of this study was to determine the sex representation among principal investigators (PIs) in US cardiac surgery clinical trials. SUMMARY BACKGROUND DATA: Being a principal investigator in a US clinical trial confers national recognition among peers. Sex representation among principal investigators (PIs) in US cardiac surgery clinical trials has not been evaluated. METHODS: We evaluated 124 US cardiac surgery trials registered on Clin-icalTrials.gov from 2014 to 2019. Sixty trials included PIs (n = 266) from 128 institutions that had a combined total of 1040 adult cardiac surgeons. We examined sex representation among junior-level (instructor or assistant professor) and senior-level (associate, full, or Emeritus professor) PIs by calculating the participation-to-prevalence ratio (PPR), whereby a PPR range of 0.8 to 1.2 reflects equitable representation. RESULTS: The pool representation percentage was 6.1% (63/1040) for women and 93.9% (977/1040) for men. A total of 266 PI positions were assigned to adult cardiac surgeons: 6 (9.5%; PPR = 0.37) from the female pool and 260 (26.6%; PPR = 1.04) from the male pool ( P = 0.004). The percentage of PIs with studies funded by industry was 9.5% ofthe female pool (PPR = 0.39) and 25.0% of the male pool (PPR = 1.04) ( P = 0.009). No National Institutes of Health-funded or other funded trials had female PIs. An overall trend was observed toward disproportionally more men than women among PIs, especially at the senior level ( P = 0.027). CONCLUSIONS: Equitable opportunities for PI positions are available for junior-level but not senior-level cardiothoracic surgeons. These results suggest a need for active engagement and promotion of equal opportunities in cardiac surgery.

BACKGROUND: Women have been historically under-represented in vascular surgery and cardiovascular medicine trials. The rate and change in representation of women in trials of common vascular diseases over the last decade is not understood completely. METHODS: We used publicly available data from ClinicalTrials.gov to evaluate trials pertaining to carotid artery stenosis (CAS), peripheral arterial disease (PAD), thoracic and abdominal aortic aneurysms (TAA and AAA), and type B aortic dissections (TBAD) from 2008 to the present. We evaluated representation of women in these trials based on the participation-to-prevalence ratios (PPR), which are calculated by dividing the percentage of women among trial participants by the percentage of women in the disease population. Values of 0.8 to 1.2 reflect similar representation. RESULTS: The sex distribution was reported in all 97 trials, including 11 CAS trials, 68 PAD trials, 16 TAA/AAA trials, and 2 TBAD trials. The total number of participants in these trials was 41,622 and the median number of participants per trial was 150.5 (interquartile range [IQR], 50-252). The percentage of women in the disease population was 51.9% for CAS, 53.1% for PAD, 34.1% for TAA/AAA, and 30.9% for TBAD. Industry sources funded 76 of the trials (77.6%), and the Veterans Affairs Administration (n = 4 [4.1%]), unspecified university (n = 7 [7.1%]), and extramural sources (n = 11 [11.2%]) funded the remainder of the trials. The overall median PPR for all four diseases was 0.65 (IQR, 0.51-0.80). Women were under-represented for all four conditions studied (CAS, 0.73 [IQR, 0.62-0.96]; PAD, 0.65 [IQR, 0.53-0.77]; TAA/AAA, 0.59 [IQR, 0.38-1.20]; and TBAD, 0.74 [IQR, 0.65-0.84]). There was no significant difference in PPR among the diseases (P = .88). From 2008 to the present, there was no significant change in PPR values over time overall (r2 = 0.002; P = .70). When examined individually, PPR did not change significantly over time for any of the diseases studied (for each, r2 < 0.04; P > .45). The PPR did not vary significantly over time for any of the funding sources (for each, r2 < 0.85, P > .08). There was appropriate representation (PPR of 0.8-1.2) in a minority of trials for each disease except TBAD (CAS, 27.3%; PAD, 15.9%; TAA/AAA, 18.8%; and TBAD, 50%). Trials that were primarily funded from university sources had the highest median PPR (1.04; IQR, 0.21-1.27), followed by industry-funded (0.67; IQR, 0.54-0.81), and extramurally funded (0.60; IQR, 0.34-0.73). Studies funded by Veterans Affairs had the lowest PPR (0.02; IQR, 0.00-0.11; P = .004). CONCLUSIONS: Participation of women in US trials of common vascular diseases remains low and has not improved since 2008. Therefore, the generalizability of recent trial results to women with these vascular diseases remains unknown. An improved understanding of the underlying root causes for poor female trial participation, advocacy, and education are required to improve the generalizability of trial results for female vascular patients.

Brain protection during open distal aortic arch replacement surgery is of utmost importance. Hypothermia in combination with cerebral perfusion offers optimal results by maintaining the brain's metabolic supply. Both retrograde cerebral perfusion and antegrade cerebral perfusion, used in combination with hypothermia, produce comparable results when the hypothermic circulatory arrest times are short; in contrast, for longer perfusion times, most aortic surgery centers are trending toward the use of antegrade rather than retrograde cerebral perfusion. Our own preference has been to use a bilateral mode of delivering antegrade cerebral perfusion instead of a unilateral approach, as bilateral perfusion appears to be more protective. We maintain that there is no harm in perfusing both brain hemispheres, so long as an appropriate balloon-tipped catheter is used carefully and manipulation of the head vessels is avoided.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact on health care and cardiac surgery. We report cardiac surgeons' concerns, perceptions, and responses during the COVID-19 pandemic. METHODS: A detailed survey was sent to recruit participating adult cardiac surgery centers in North America. Data regarding cardiac surgeons' perceptions and changes in practice were analyzed. RESULTS: Our study comprises 67 institutions with diverse geographic distribution across North America. Nurses were most likely to be redeployed (88%), followed by advanced care practitioners (69%), trainees (28%), and surgeons (25%). Examining surgeon concerns in regard to COVID-19, they were most worried with exposing their family to COVID-19 (81%), followed by contracting COVID-19 (68%), running out of personal protective equipment (PPE) (28%), and hospital resources (28%). In terms of PPE conservation strategies among users of N95 respirators, nearly half were recycling via decontamination with ultraviolet light (49%), followed by sterilization with heat (13%) and at home or with other modalities (13%). Reuse of N95 respirators for 1 day (22%), 1 week (21%) or 1 month (6%) was reported. There were differences in adoption of methods to conserve N95 respirators based on institutional pandemic phase and COVID-19 burden, with higher COVID-19 burden institutions more likely to resort to PPE conservation strategies. CONCLUSIONS: The present study demonstrates the impact of COVID-19 on North American cardiac surgeons. Our study should stimulate further discussions to identify optimal solutions to improve workforce preparedness for subsequent surges, as well as facilitate the navigation of future healthcare crises.

OBJECTIVE: We performed a systematic review and meta-analysis aiming to assess the mortality and morbidity of all published case series on thoracoabdominal aortic aneurysms (TAAAs) in experienced centers treated with open repair. METHODS: A systematic search of the literature published until April 2017 was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Separate meta-analyses were conducted for overall in-hospital mortality for TAAA, mortality according to the type of TAAA, spinal cord ischemia, paraplegia and paraparesis, cardiac events, stroke, acute kidney failure, and bowel ischemia. A metaregression analysis was performed with volume of the center, percentage of ruptured cases among the series, length of in-hospital stay, and publication year as covariates. RESULTS: A total of 30 articles were included in the meta-analysis, corresponding to a total of 9963 patients who underwent open repair for TAAAs (543 ruptured). The pooled mortality rate among all studies was 11.26% (95% confidence interval [CI], 9.56-13.09). Mortality was 6.97% (95% CI, 3.75-10.90), 10.32% (95% CI, 7.39-13.63), 8.02% (95% CI, 6.37-9.81), and 7.20% (95% CI, 4.19-10.84) for Crawford types I, II, III, and IV, respectively. Pooled spinal cord ischemia rate was estimated at 8.26% (95% CI, 6.95-9.67), whereas paraparesis and paraplegia rates were 3.61% (95% CI, 2.25-5.25) and 5% (95% CI, 4.36-5.68), respectively. We estimated a pooled cardiac event rate of 4.41% (95% CI, 1.84-7.95) and a stroke rate of 3.11% (95% CI, 2.36-3.94), whereas the need for permanent dialysis rate was 7.92% (95% CI, 5.34-10.92). Respiratory complications after surgery were as high as 23.01% (95% CI, 14.73-32.49). Metaregression analysis evidenced a statistically significant inverse association between mortality and the volume of cases performed in the vascular center (t = -2.00; P = .005). Interestingly, a more recent year of study publication tended to be associated with decreased in-hospital mortality (t = -1.35; P = .19). CONCLUSIONS: Our study showed that despite the advances in open surgical techniques, the morbidity and mortality of the technique continue to remain considerable. Despite the focus on mortality and spinal cord ischemia, respiratory complications, permanent postoperative renal dialysis, stroke rate, and cardiac events also affect the outcome. The estimated trend of lower mortality in high-volume centers suggests that perhaps this type of service should be provided in a few reference centers that have an established record and experience in the management of these patients.

OBJECTIVE: The gadolinium-based MRI contrast agent gadobenate dimeglumine has nearly twice the MR relaxivity of gadopentetate dimeglumine at 1.5 T. The purpose of this study was to determine whether a lower dose (0.1 mmol/kg) of gadobenate dimeglumine can be used to obtain delayed-enhancement MR images comparable to those obtained with a standard dose (0.2 mmol/kg) of gadopentetate dimeglumine. SUBJECTS AND METHODS: In this blinded randomized crossover study, 20 patients with known myocardial infarction underwent two separate delayed-enhancement MRI examinations after receiving 0.1 mmol/kg gadobenate dimeglumine and 0.2 mmol/kg gadopentetate dimeglumine (random administration). The conspicuity of lesion enhancement 5, 10, and 20 minutes after contrast administration was quantified as relative enhancement ratio (RER). RESULTS: With either gadolinium-based contrast agent, damaged myocardium had higher signal intensity than normal remote myocardium (RER > 4) on delayed-enhancement MR images, and the blood RER declined over time after contrast administration. The blood RER was not significantly higher for gadobenate dimeglumine than for gadopentetate dimeglumine at 5 and 10 minutes. Nevertheless, there was a larger reduction in blood RER for gadobenate dimeglumine than for gadopentetate dimeglumine between 5 and 10 minutes and between 10 and 20 minutes. The volumes of enhancement were similar for gadobenate dimeglumine (13.6 ± 8.8 cm(3)) and gadopentetate dimeglumine (13.5 ± 8.9 cm(3)) (p = 0.98). The mean difference in Bland-Altman analysis for delayed-enhancement volume between the agents was 0.1 cm(3). CONCLUSION: Qualitatively and quantitatively, delayed-enhancement MR images of ischemic myocardium obtained with 0.1 mmol/kg gadobenate dimeglumine are comparable to those obtained with 0.2 mmol/kg gadopentetate dimeglumine 5, 10, and 20 minutes after contrast administration.

OBJECTIVE: We evaluated community socioeconomic factors in patients who had unplanned readmission after undergoing proximal aortic surgery (ascending aorta, aortic root, or arch). METHODS: Unplanned readmissions for any reason within 60 days of the index procedure were reviewed by race, acuity at presentation, and gender. We also evaluated 3 community socioeconomic factors: poverty, household income, and education. Kaplan-Meier survival curves were used to assess long-term survival differences by group (race, acuity, and gender). RESULTS: Among 2339 patients who underwent proximal aortic surgery during the 20-year study period and were discharged alive, our team identified 146 (6.2%) unplanned readmissions. Compared with White patients, Black patients lived in areas characterized by more widespread poverty (20.8% vs 11.1%; P = .0003), lower income ($42,776 vs $65,193; P = .0007), and fewer residents with a high school diploma (73.7% vs 90.1%; P < .0001). Compared with patients whose index operation was elective, patients who had urgent or emergency index procedures lived in areas with lower income ($54,425 vs $64,846; P = .01) and fewer residents with a high school diploma (81.1% vs 89.2%; P = .005). Community socioeconomic factors did not differ by gender. Four- and 6-year survival estimates were 63.1% and 63.1% for Black patients versus 89.1% and 83.0% for White patients (P = .0009). No significant differences by acuity or gender were found. CONCLUSIONS: Among readmitted patients, Black patients and patients who had emergency surgery had less favorable community socioeconomic factors and poorer long-term survival. Earlier and more frequent follow-up in these patients should be considered. Developing off-campus clinics and specific postdischarge measures targeting these patients is important.
RESUMO
OBJECTIVE: We examined the relationship between Black or White race and adverse outcomes in patients who underwent surgery of the ascending aorta, aortic root, or aortic arch at our center. METHODS: We analyzed 2335 consecutive patients who identified as Black (n = 217, 9.3%) or White (n = 2118, 90.7%) and underwent proximal aortic surgery. Patient zip codes were used to determine community socioeconomic (CSE) characteristics. The composite adverse outcome comprised mortality, persistent neurologic injury, and renal failure necessitating dialysis at discharge. We performed multivariable analysis, Kaplan-Meier analysis, and propensity score matching adjusted for CSE factors. RESULTS: Median follow-up time was 3.7 years. Compared with White patients, Black patients lived in areas characterized by a higher percentage living below poverty level, lower income, and lower education level (P < .0001). Black patients had higher rates of emergency presentation (P < .0001) and lower 5- and 10-year survival rates (P = .0002). Short-term outcomes were similar between groups, except for respiratory failure and length of stay (P < .0001), which were higher in the Black population. After propensity score matching adjusted for CSE factors, Black and White patients (n = 204 each) had similar short-term outcomes and 5- and 10-year survival rates (P = .30). Multivariable analysis stratified by race showed that CSE factors independently predicted adverse outcomes in Black but not White patients. CONCLUSIONS: This is among few studies that have analyzed the relationship between race and proximal aortic surgery. Although outcomes were similar between Black and White patients in our cohort after adjusting for CSE factors, unfavorable CSE factors predicted adverse outcomes in Black but not White patients. More patient-specific studies are needed.

BACKGROUND: The utility of operating room extubation (ORE) after cardiac surgery over fast-track extubation (FTE) within 6 hours remains contested. We hypothesized ORE would be associated with equivalent rates of morbidity and mortality, relative to FTE. METHODS: Patients undergoing nonemergent cardiac surgery were identified in The Society of Thoracic Surgeons Adult Cardiac Surgery Database between July 2017 and December 2022. Only procedures with The Society of Thoracic Surgeons risk models were included. Risk-adjusted outcomes of ORE and FTE were compared by observed-to-expected ratios with 95% CIs aggregated over all procedure types, and ORE vs FTE adjusted odds ratios (ORs) specific to each procedure type using multivariable logistic regression. Analyzed outcomes were operative mortality, prolonged length of stay, composite reoperation for bleeding and reintubation, and composite morbidity and mortality. RESULTS: The study population of 669,099 patients across 1069 hospitals included 36,298 ORE patients in 296 hospitals. Risk-adjusted analyses found that ORE was associated with statistically similar or better results across each of the 4 outcomes and procedure subtypes. Notably, rates of postoperative mortality were significantly lower in ORE patients undergoing coronary artery bypass grafting (OR, 0.54; 95% CI, 0.46-0.65), aortic valve replacement (OR, 0.43; 95% CI, 0.24-0.77), and mitral valve replacement (OR, 0.48; 95% CI, 0.26-0.89). CONCLUSIONS: Extubation in the OR was safe and effective in a selected patient population and may be associated with superior outcomes in coronary artery bypass, aortic valve replacement, and mitral valve replacement. These national data appear to confirm institutional experiences regarding the potential benefit of OR extubation. Further refinement of optimal populations may justify randomized investigation.
RESUMO
BACKGROUND: Without surgical repair, acute type A aortic dissection (TAAD) is usually fatal. However, some patients survive without an early operation and progress to the chronic phase. Contemporary outcomes of primary surgical repair of chronic TAAD are unclear, so we evaluated them at our single-practice service. METHODS: During 1990 to 2021, 205 patients underwent repair of TAAD in the chronic phase (>60 days after onset). The 2 relevant DeBakey classifications were nearly equally represented: type I, 52% (n = 107), and type II, 48% (n = 98). The median interval between dissection onset and repair was 7 months (interquartile range, 3-25 months). Kaplan-Meier and competing-risk analyses provided time-dependent outcomes. RESULTS: At the time of intervention, most patients (40%) had chronic symptoms. Type I patients were younger than type II patients; however, comorbidities were similar. Most patients (n = 183 [87%]) underwent hemiarch or total arch repair, although total arch replacement was more common in type I dissection (P < .001). There were 15 operative deaths (7%), and 7 strokes (3%) persisted to the time of death or discharge. No patient had persistent paraplegia. Median follow-up was 5 years (interquartile range, 2-11 years). The 5-year reoperation-free survival was 61% (95% CI, 54%-68%), and the incidence of reoperation was 3% (95% CI, 0.4%-5%). Patients with type I and type II dissection did not differ significantly in survival (P = .2). CONCLUSIONS: Durable repair can be achieved with reasonable operative risk. Treatment is individualized and is associated with low rates of persistent neurologic complications. Despite differing operative approaches by DeBakey type, early and late outcomes were similar.

OBJECTIVE: We evaluated the relationship among community socioeconomic factors (poverty, income, and education), gender, and outcomes in patients who underwent ascending aortic, root, and arch surgery. METHODS: For 2634 consecutive patients, we associated patients' ZIP codes with community socioeconomic factors. The composite adverse outcome comprised death, persistent neurological injury, and renal failure necessitating dialysis at discharge. Multivariable analysis and Kaplan-Meier survival curves were used. Men and women from the full cohort and from the elective patients were propensity matched. RESULTS: Median follow-up was 3.6 years (interquartile range, 1.2-9.3). Men lived in areas characterized by less poverty (P = .03), higher household income (P = .01), and more education (P = .02) than women; likewise, in the elective cohort, all community socioeconomic factors favored men (P ≤ .009). Female gender predicted composite adverse outcome (P = .006). In the propensity-matched women and men (820 pairs), the composite adverse outcome rates were 14.2% and 11%, respectively (P = .06). In 583 propensity-matched pairs of elective patients, men had less composite adverse outcome (P = .02), operative mortality (P = .04), and renal (P = .02) and respiratory failure (P = .0006). The 5- and 10-year survivals for these men and women were 74.2% versus 71.4% and 50.2% versus 48.2%, respectively (P = .06). All community socioeconomic factors in both propensity-matched groups nonsignificantly favored men. CONCLUSIONS: This study is among the first to examine the association among community socioeconomic factors, gender, and outcomes in patients who undergo proximal aortic surgery. Female gender predicted a composite adverse outcome. In the elective patients, most adverse outcomes were significantly less in men. In the propensity-matched patients, all community socioeconomic factors favored men, although not significantly. Larger studies with patient-level socioeconomic information are needed.

Every effort must be made by the leaders in our field, as well as by every individual cardiothoracic surgeon, to assure equal opportunity for all cardiothoracic surgeons, regardless of race, gender or any other sociodemographic source of bias. Every effort must be made by every surgeon, not just those in particular leadership roles. Opportunities for advancement must be equal in multiple domains, including clinical practice, patient referral, clinical leadership, academic leadership, institutional leadership and leadership in professional medical and surgical societies. Such actions to minimize bias and promote inclusivity will also ensure that cardiothoracic surgical care is provided by a workforce that represents the diversity of patients whom we serve. In the final analysis, it is an absolute fact that gender differences in payments to cardiothoracic surgeons are absolutely unacceptable and cannot be tolerated.

Spinal cord deficit (SCD) is a feared complication after thoracoabdominal aortic aneurysm repair. Vigilant management throughout the perioperative period is necessary to reduce the risk of SCD. Measures for preventing SCD during the intraoperative period include preoperative optimization and recognizing patients at a higher risk of SCD. In this manuscript, we discuss intraoperative adjuncts including utilization of cerebrospinal fluid drainage, left heart bypass, mild hypothermia, selective reimplantation of intercostal and lumbar arteries, and renal and visceral vessel perfusion. From the operative to the postoperative period, careful attention to avoiding hypotension and anemia is important. If SCD is recognized early, therapeutic intervention may be implemented to mitigate injury.
RESUMO
BACKGROUND: The integrated 6-year thoracic surgery (I-6) residency model was developed in part to promote early interest in cardiothoracic surgery in diverse trainees. To determine gaps in and opportunities for recruitment of women and minority groups in the pipeline for I-6 residency, we quantified rates of progression at each training level and trends over time. METHODS: We obtained 2015 to 2019 medical student, I-6 applicant, and I-6 resident gender and race/ethnicity demographic data from the American Association of Medical Colleges and Electronic Residency Application Service public databases and Accreditation Council for Graduate Medical Education Data Resource Books. We performed χ2, Fisher exact, and Cochran-Armitage tests for trend to compare 2015 and 2019. RESULTS: Our cross-sectional analysis found increased representation of women and all non-White races/ethnicities, except Native American, at each training level from 2015 to 2019 (P < .001 for all). The greatest trends in increases were seen in the proportions of women (28% vs 22%, P = .46) and Asian/Pacific Islander (25% vs 15%, P = .08) applicants. There was also an increase in the proportions of women (28% vs 24%, P = .024) and White (61% vs 58%, P = .007) I-6 residents, with a trend for Asian/Pacific Islanders (20% vs 17%, P = .08). The proportions of Hispanic (5%) and Black/African American (2%) I-6 residents in 2019 remained low. CONCLUSIONS: I-6 residency matriculation is not representative of medical student demographics and spotlights a need to foster early interest in cardiothoracic surgery among all groups underrepresented in medicine while ensuring that we mitigate bias in residency recruitment.

OBJECTIVE: Sarcopenia (core muscle loss) has been used as a surrogate marker of frailty. We investigated whether sarcopenia would adversely affect survival after thoracoabdominal aortic aneurysm repair. METHODS: We retrospectively reviewed prospectively collected data from patients aged 60 years or older who underwent thoracoabdominal aortic aneurysm repairs from 2006 to 2016. Imaging was reviewed by 2 radiologists blinded to clinical outcomes. The total psoas index was derived from total psoas muscle cross-sectional area (cm2) at the mid-L4 level, normalized for height (m2). Patients were divided by sex-specific total psoas index values into sarcopenia (lower third) and nonsarcopenia (upper two-thirds) groups. Multivariable modeling identified operative mortality and spinal cord injury predictors. Unadjusted and adjusted survival curves were analyzed. RESULTS: Of 392 patients identified, those with sarcopenia (n = 131) were older than nonsarcopenic patients (n = 261) (70.0 years vs 68.0 years; P = .02) and more frequently presented with aortic rupture or required urgent/emergency operations. Operative mortality was comparable (sarcopenia 13.7% vs nonsarcopenia 10.0%; P = .3); sarcopenia was not associated with operative mortality in the multivariable model (odds ratio, 1.40; 95% confidence interval, 0.73-2.77; P = .3). Sarcopenic patients experienced more frequent delayed (13.0% vs 4.6%; P = .005) and persistent (10.7% vs 3.4%; P = .008) paraplegia. Sarcopenia independently predicted delayed paraplegia (odds ratio, 3.17; 95% confidence interval, 1.42-7.08; P = .005) and persistent paraplegia (odds ratio, 3.29; 95% confidence interval, 1.33-8.13; P = .01) in the multivariable model. Adjusted for preoperative/operative covariates, midterm survival was similar for sarcopenic and nonsarcopenic patients (P = .3). CONCLUSIONS: Sarcopenia did not influence early mortality or midterm survival after thoracoabdominal aortic aneurysm repair but was associated with greater risk for delayed and persistent paraplegia.
