RESUMO
INTRODUCTION: Women continue to be underrepresented in academic anesthesiology. This study assessed guidelines in anesthesia journals over the past 5 years, evaluating differences in woman-led versus man-led guidelines in terms of author gender, quality, and changes over time. We hypothesized that anesthesia guidelines would be predominately man-led, and that there would be differences in quality between woman-led versus man-led guidelines. METHODS: All clinical practice guidelines published in the top 10 anesthesia journals were identified as per Clarivate Analytics Impact Factor between 2016 and 2020. Fifty-one guidelines were included for author, gender, and quality analysis using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Each guideline was assessed across 6 domains and 23 items and given an overall score, overall quality score, and overall rating/recommendation. Stratified and trend analyses were performed for woman-led versus man-led guidelines. RESULTS: Fifty out of 51 guidelines were included: 1 was excluded due to unidentifiable first-author gender. In total, 255 of 1052 (24%) authors were women, and woman-led guidelines (woman-first author) represented 12 of 50 (24%) overall guidelines. Eighteen percent (9 of 50) of guidelines had all-male authors, and a majority (26 of 50, 52%) had less than one-third of female authors. The overall number and percentage of woman-led guidelines did not change over time. There was a significantly higher percentage of female authors in woman-led versus man-led guidelines, median 39% vs 20% (P = .012), as well as a significantly higher number of female coauthors in guidelines that were woman-led median 3.5 vs 1.0, P = .049. For quality, there was no significant difference in the overall rating or objective quality of woman- versus man-led guidelines. However, there was a significant increase in the overall rating of all the guidelines over time (P = .010), driven by the increase in overall rating among man-led guidelines, P = .002. The overall score of guidelines did not increase over time; however, they increased in man-led but not woman-led guidelines. There was no significant correlation between the percentage of female authors per guideline and either overall score or overall rating. CONCLUSIONS: There is a substantial disparity in the number of women leading and contributing to guidelines which has not improved over time. Woman-led guidelines included more women and a higher percentage of women. There was no difference in quality of guidelines by first-author gender or percentage of female authors. Further systematic and quota-driven sponsorship is needed to promote gender equity, diversity, and inclusion in anesthesia guidelines.
RESUMO
BACKGROUND: In the Posterior left pericardiotomy for the prevention of atrial fibrillation after cardiac surgery (PALACS) trial, posterior pericardiotomy was associated with a significant reduction in postoperative atrial fibrillation (POAF) after cardiac surgery. We aimed to investigate the mechanisms underlying this effect. METHODS: We included PALACS patients with available echocardiographic data (n = 387/420, 92%). We tested the hypotheses that the reduction in POAF with the intervention was associated with 1) a reduction in postoperative pericardial effusion and/or 2) an effect on left atrial size and function. Spline and multivariable logistic regression analyses were used. RESULTS: Most patients (n = 307, 79%) had postoperative pericardial effusions (anterior 68%, postero-lateral 51.9%). The incidence of postero-lateral effusion was significantly lower in patients undergoing pericardiotomy (37% vs 67%; P < .001). The median size of anterior effusion was comparable between patients with and without POAF (5.0 [IQR 3.0-7.0] vs 5.0 [IQR 3.0-7.5] mm; P = .42), but there was a nonsignificant trend towards larger postero-lateral effusion in the POAF group (5.0 [IQR 3.0-9.0] vs 4.0 [IQR 3.0-6.4] mm; P = .06). There was a non-linear association between postero-lateral effusion and POAF at a cut-off at 10 mm (OR 2.70; 95% CI 1.13, 6.47; P = .03) that was confirmed in multivariable analysis (OR 3.5, 95% CI 1.17, 10.58; P = 0.02). Left atrial dimension and function did not change significantly after posterior pericardiotomy. CONCLUSIONS: Reduction in postero-lateral pericardial effusion is a plausible mechanism for the effect of posterior pericardiotomy in reducing POAF. Measures to reduce postoperative pericardial effusion are a promising approach to prevent POAF.

BACKGROUND: Minimally invasive surgery is an expanding field of surgery that has replaced many open surgical techniques. Surgery remains a cornerstone in the treatment of esophageal cancer, yet it is still associated with significant morbidity and technical difficulties. Mediastinoscope-assisted esophagectomy is a promising technique that aims to decrease the surgical burden and enhance recovery. METHODS: PubMed, MEDLINE, and EMBASE databases were searched for publications on mediastinoscope-assisted esophagectomies for esophageal cancer. The primary endpoint was a postoperative anastomotic leak, while secondary endpoints were assessment of harvested lymph nodes (LNs), blood loss, chyle leak, hospital length of stay (LOS), operative (OR) time, pneumonia, wound infection, mortality, and microscopic positive margin (R1). The pooled event rate (PER) and pooled mean were calculated for binary and continuous outcomes respectively. RESULTS: Twenty-six out of the 2274 searched studies were included. The pooled event rate (PER) for anastomotic leak was 0.145 (0.1144; 0.1828). The PERs for chyle leak, recurrent laryngeal nerve injury/hoarseness, postoperative pneumonia, wound infection, early mortality, postoperative morbidity, and microscopically positive (R1) resection margins were 0.027, 0.185, 0.09, 0.083, 0.020, 0.378, and 0.037 respectively. The pooled means for blood loss, hospital stay, operative time, number of total harvested LNs, and number of harvested thoracic LNs were 159.209, 15.187, 311.116, 23.379, and 15.458 respectively. CONCLUSIONS: Mediastinoscopic esophagectomy is a promising minimally invasive technique, avoiding thoracotomy, patient repositioning, and lung manipulation; thus allowing for shorter surgery, decreased blood loss, and decreased postoperative morbidity. It can also be reliable in terms of oncological safety and LN dissection.

OBJECTIVE: Open repair of acute complicated type B aortic dissection (ACTBAD), required when endovascular repair is not possible, is historically considered high-risk. We analyze our experience with this high-risk cohort compared with the standard cohort. METHODS: We identified consecutive patients undergoing descending thoracic or thoracoabdominal aortic aneurysm (TAAA) repair from 1997 to 2021. Patients with ACTBAD were compared with those having surgery for other reasons. Logistic regression was used to identify associations with major adverse events (MAEs). Five-year survival and competing risk of reintervention were calculated. RESULTS: Of 926 patients, 75 (8.1%) had ACTBAD. Indications included rupture (25/75), malperfusion (11/75), rapid expansion (26/75), recurrent pain (12/75), large aneurysm (5/75), and uncontrolled hypertension (1/75). The incidence of MAEs was similar (13.3% [10/75] vs 13.7% [117/851], P = .99). Operative mortality was 5.3% (4/75) vs 4.8% (41/851) (P = .99). Complications included tracheostomy (8%, 6/75), spinal cord ischemia (4%, 3/75), and new dialysis (2.7%, 2/75). Renal impairment, urgent/emergent operation, forced expiratory volume in 1 second ≤50%, and malperfusion were associated with MAEs, but not ACTBAD (odds ratio: 0.48, 95% confidence interval [CI]: [0.20-1.16], P = .1). At 5 and 10 years, there was no difference in survival (65.8% [95% CI: 54.6-79.2] vs 71.3% [95% CI: 67.9-74.9], P = .42, and 47.3% [95% CI: 34.5-64.7] vs 53.7% [95% CI: 49.3-58.4], P = .29, respectively) or 10-year reintervention (12.5% [95% CI: 4.3-25.3] vs 7.1% [95% CI: 4.7-10.1], P = .17, respectively). CONCLUSIONS: In an experienced center, open repair of ACTBAD can be performed with low rates of operative mortality and morbidity. Outcomes similar to elective repair are achievable even in high-risk patients with ACTBAD. In patients unsuitable for endovascular repair, transfer to a high-volume center experienced in open repair should be considered.

BACKGROUND: Nonmetastatic T4b colon cancer has been traditionally treated with upfront surgery, often requiring technically challenging multiorgan resection. Neoadjuvant chemotherapy can potentially downsize these tumors and improve their resectability. OBJECTIVE: This study aimed to explore trends and outcomes of neoadjuvant chemotherapy use compared to upfront surgery in patients with nonmetastatic T4b colon cancer. This study also sought to determine factors associated with increased neoadjuvant chemotherapy use and with overall survival. DESIGN: Retrospective cohort study. SETTINGS: Conducted using the National Cancer Database. PATIENTS: Patients with nonmetastatic T4b colon cancer who underwent colectomy (2006-2016) were included in the study. Patients receiving neoadjuvant chemotherapy were propensity-matched (1:2) to those who underwent upfront surgery in either clinically node-negative or node-positive disease. MAIN OUTCOME MEASURES: Postoperative outcomes (length of stay, 30-d readmission, 30/90-d mortality), oncologic resection adequacy (R0 rate, number of resected/positive nodes), and overall survival were the main outcome measures. RESULTS: Neoadjuvant chemotherapy was used in 7.7% of the patients. Neoadjuvant chemotherapy use increased over the study period from 4% to 16% in the entire cohort, from 3% to 21% in patients with clinically node-positive disease, and from 6% to 12% in patients with clinically node-negative disease. Factors associated with increased use of neoadjuvant chemotherapy included younger age (OR 0.97; 95% CI, 0.96-0.98; p < 0.001), male sex (OR 1.35; 95% CI, 1.11-1.64; p = 0.002), recent diagnosis year (OR 1.16; 95% CI, 1.12-1.20; p < 0.001), academic centers (OR 2.65; 95% CI, 2.19-3.22; p < 0.001), clinically node-positive (OR 1.23; 95% CI, 1.01-1.49; p = 0.037), and tumor located in the sigmoid colon (OR 2.44; 95% CI, 1.97-3.02; p < 0.001). Patients who received neoadjuvant chemotherapy had significantly higher R0 resection compared with upfront surgery (87% vs 77%; p < 0.001). On multivariable analysis, neoadjuvant chemotherapy was associated with higher overall survival (HR 0.76; 95% CI, 0.64-0.91; p = 0.002). On propensity-matched analyses, neoadjuvant chemotherapy was associated with a higher 5-year overall survival compared to upfront surgery in patients with clinically node-positive disease (57% vs 43%; p = 0.003) but not in patients with clinically node-negative disease (61% vs 56%; p = 0.090). LIMITATIONS: Retrospective design. CONCLUSION: Neoadjuvant chemotherapy use for nonmetastatic T4b has increased significantly on the national level, more so in patients with clinically node-positive disease. Patients with node-positive disease treated with neoadjuvant chemotherapy had higher overall survival compared to those who underwent upfront surgery.

AIMS: To evaluate the impact of multiple arterial grafting (MAG) vs. single arterial grafting (SAG) in a post hoc analysis of 10-year outcomes in patients with diabetes mellitus (DM) from the Arterial Revascularization Trial (ART). METHODS AND RESULTS: The primary endpoint was all-cause mortality and the secondary endpoint was a composite of major adverse cardiac events (MACE) at 10-year follow-up. Patients were stratified by diabetes status (non-DM and DM) and grafting strategy (MAG vs. SAG). A total of 3020 patients were included in the analysis; 716 (23.7%) had DM. Overall, 55.8% non-DM patients received MAG and 44.2% received SAG, while 56.6% DM patients received MAG and 43.4% received SAG. The use of MAG compared with SAG was associated with lower 10-year mortality for both non-DM [17.7 vs. 21.0%, adjusted hazard ratio (HR) 0.87, 95% confidence interval (CI) 0.72-1.06] and DM patients (21.5 vs. 29.9%, adjusted HR 0.65, 95% CI 0.48-0.89; P for interaction = 0.12). For both groups, the rate of 10-year MACE was also lower for MAG vs. SAG. Overall, deep sternal wound infections (DSWIs) were uncommon but more frequent in the MAG vs. SAG group in both non-DM (3.3 vs. 2.1%) and DM patients (7.9 vs. 4.8%). The highest rates of DSWI were in insulin-treated patients receiving MAG (9.6 vs. 6.3%, when compared with SAG). CONCLUSION: In this post hoc analysis of the ART, MAG was associated with substantially lower mortality rates at 10 years after coronary artery bypass grafting in patients with DM. Patients with DM receiving MAG had a higher incidence of DSWI, especially if insulin dependent.

BACKGROUND: Atrial fibrillation is the most common complication after cardiac surgery and is associated with extended in-hospital stay and increased adverse outcomes, including death and stroke. Pericardial effusion is common after cardiac surgery and can trigger atrial fibrillation. We tested the hypothesis that posterior left pericardiotomy, a surgical manoeuvre that drains the pericardial space into the left pleural cavity, might reduce the incidence of atrial fibrillation after cardiac surgery. METHODS: In this adaptive, randomised, controlled trial, we recruited adult patients (aged ≥18 years) undergoing elective interventions on the coronary arteries, aortic valve, or ascending aorta, or a combination of these, performed by members of the Department of Cardiothoracic Surgery from Weill Cornell Medicine at the New York Presbyterian Hospital in New York, NY, USA. Patients were eligible if they had no history of atrial fibrillation or other arrhythmias or contraindications to the experimental intervention. Eligible patients were randomly assigned (1:1), stratified by CHA2DS2-VASc score and using a mixed-block randomisation approach (block sizes of 4, 6, and 8), to posterior left pericardiotomy or no intervention. Patients and assessors were blinded to treatment assignment. Patients were followed up until 30 days after hospital discharge. The primary outcome was the incidence of atrial fibrillation during postoperative in-hospital stay, which was assessed in the intention-to-treat (ITT) population. Safety was assessed in the as-treated population. This study is registered with ClinicalTrials.gov, NCT02875405, and is now complete. FINDINGS: Between Sept 18, 2017, and Aug 2, 2021, 3601 patients were screened and 420 were included and randomly assigned to the posterior left pericardiotomy group (n=212) or the no intervention group (n=208; ITT population). The median age was 61·0 years (IQR 53·0-70·0), 102 (24%) patients were female, and 318 (76%) were male, with a median CHA2DS2-VASc score of 2·0 (IQR 1·0-3·0). The two groups were balanced with respect to clinical and surgical characteristics. No patients were lost to follow-up and data completeness was 100%. Three patients in the posterior left pericardiotomy group did not receive the intervention. In the ITT population, the incidence of postoperative atrial fibrillation was significantly lower in the posterior left pericardiotomy group than in the no intervention group (37 [17%] of 212 vs 66 [32%] of 208 [p=0·0007]; odds ratio adjusted for the stratification variable 0·44 [95% CI 0·27-0·70; p=0·0005]). Two (1%) of 209 patients in the posterior left pericardiotomy group and one (<1%) of 211 in the no intervention group died within 30 days after hospital discharge. The incidence of postoperative pericardial effusion was lower in the posterior left pericardiotomy group than in the no intervention group (26 [12%] of 209 vs 45 [21%] of 211; relative risk 0·58 [95% CI 0·37-0·91]). Postoperative major adverse events occurred in six (3%) patients in the posterior left pericardiotomy group and in four (2%) in the no intervention group. No posterior left pericardiotomy related complications were seen. INTERPRETATION: Posterior left pericardiotomy is highly effective in reducing the incidence of atrial fibrillation after surgery on the coronary arteries, aortic valve, or ascending aorta, or a combination of these without additional risk of postoperative complications. FUNDING: None.

We conducted this meta-analysis to address the outcomes in cancer patients after oncologic surgery during COVID-19 pandemic. The primary endpoint was the COVID-19-related mortality rate. Higher body mass index was significantly and negatively associated with higher all-cause mortality and in-hospital COVID-19 infection rates. Male sex, preoperative respiratory disease, and smoking history were positively and significantly associated with increased all-cause mortality rates. Furthermore, male sex was positively and significantly associated with the COVID-19 infection rate.

BACKGROUND: Guidance documents are a valuable resource to clinicians to guide evidenced-based decision making. The quality of guidelines in anaesthesia and across other specialties has been demonstrated to be poor. COVID-19 presented an urgent need for immediate guidance for anaesthetists as frontline clinicians. The aim of this study was to evaluate the quality of COVID-19 guidance documents using the internationally validated Appraisal of Guidelines for Research & Evaluation (AGREE) II tool. METHODS: A search was conducted in Ovid EMBASE and Ovid MEDLINE to identify all COVID-19 anaesthesia guidance documents from 2020-2021. Thirty-eight guidance documents were selected for analysis by 4 independent appraisers using the AGREE II instrument, across its 6 domains and 23 items. A scoring threshold for high quality was agreed by the working group via consensus. RESULTS: Overall, the body of COVID-19 guidance documents achieved poor scores using AGREE II. Only 5% of documents met the high-quality criteria. Markers of quality included international and multi-institutional collaboration. Document title ('guideline' vs 'consensus statement'/ 'recommendations') did not yield any differences in domain scores and overall quality ratings. Compared with recent general anaesthesia guidelines, COVID-19 guidelines performed significantly worse. CONCLUSIONS: COVID-19 guidance documents published during the first two years of the pandemic lacked rigour and appropriate quality. This raises concern about their trustworthiness for use in clinical practice. Enhanced systems are required to ensure the integrity of rapidly formulated guidance.

Clinical practice guidelines are a valuable resource aiding medical decision-making based on scientific evidence. In anaesthesia, guidelines are increasing in both number and scope, influencing individual practice and shaping local departmental policy. The aim of this review is to assess the quality of clinical practice guidelines published in high impact anaesthesia journals over the past 5 yr using the internationally validated Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. A literature search was conducted in Scopus to identify all guidelines published in the top 10 anaesthesia journals as per Clarivate Analytics Impact Factor from 2016 and 2020. Fifty-one guidelines were included for analysis by five independent appraisers using AGREE II. Each guideline was assessed across six domains and 23 items. Individual domain scores were calculated with a threshold agreed via consensus to represent high-quality guidelines. There was a significant increase in overall score over time (P=0.041), driven by Domain 3 (Rigour of Development, P=0.046). The raw overall score for Domain 3, however, was low. The other domains performed as expected based on previous studies, with Domains 1, 4, and 6 achieving high scores and Domains 2 and 5 incurring poor ratings. Most guidelines studied involved international collaboration but emerged from a single professional society. Use of an appraisal tool was stated as high but poorly detailed. The improvement in the overall score of guidelines and rigour of development is promising; however, only seven guidelines met high-quality criteria, suggesting room for improvement for the overall integrity of guidelines in anaesthesia.

OBJECTIVES: No systematic studies on retractions in cardiothoracic and vascular anesthesia exist. The aim of this analysis was to identify characteristics and trends of retractions in this field over the past three decades. DESIGN: A search of the Retraction Watch Database for retracted articles published between 1990 and 2020 in the field of cardiothoracic and vascular anesthesia was performed. SETTING: A bibliometric study. PARTICIPANTS: Five thousand three hundred forty-four retractions with the term "medicine" in the subject code were selected. Retractions of full-length English articles reporting findings in cardiothoracic and vascular anesthesia were included. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 63 articles published in 31 journals from January 1990 to August 2020 were retracted. The majority were original articles (n = 60, 95.2%) and retracted for scientific misconduct (n = 50, 79.4%). The percentage of retractions due to misconduct increased from 2010, with a spike in 2011 (n = 26/50, 52.0%), and reached a plateau in 2014. The three most common reasons for retraction were misconduct by the author (n = 31, 49.2%), duplication (n = 12, 19.0%), and errors within the manuscript (n = 11, 17.5%). The median time from publication to retraction was 4.3 years (IQR: 1.7-9.4) and decreased significantly over time (p < 0.001). The median impact factor (IF) of the journals that published retracted articles was 3.5 (IQR 2.0-4.5) and decreased significantly over the study period (p < 0.001). CONCLUSION: Scientific misconduct represents the most common reason for retraction in cardiothoracic and vascular anesthesia. The median time to retraction and journal IF decreased significantly over time. While this is promising, future efforts should be made to screen for falsified data and standardize the processes after retraction to highlight problematic manuscripts.

OBJECTIVE: Whereas left atrial (LA) strain has been well-validated using transthoracic echocardiography (TTE), its detection using transesophageal echocardiography (TEE) has not been studied. Conventional transesophageal views are known to be limited due to the posterior location of the LA. Here, the feasibility and accuracy of the deep transgastric long-axis LA focused view for peak atrial longitudinal strain (PALS) quantification was tested. DESIGN: This was a retrospective study of patients who underwent elective cardiac surgery between 2018 and 2020. TEE deep transgastric long-axis view was compared to TTE 4-chamber atrial focused view as the reference standard. LA area, volume, and PALS were quantified independently. SETTING: At Weill Cornell Medicine, a single, large academic medical center. PARTICIPANTS: The population comprised 42 patients undergoing cardiac surgery who had a TTE and TEE within 14.9 ± 20.8 days. INTERVENTIONS: TTE, TEE, and cardiac surgery. MEASUREMENTS AND MAIN RESULTS: TEE-derived PALS strongly correlated with TTE- derived PALS (r = 0.92, p < 0.001), though absolute PALS were lower (20.7 ± 6.0% v 25.7 ± 6.8%; p < 0.001). Mean TEE-derived atrial length was similar to TTE-derived length (5.18 ± 0.61 cm v 5.24 ± 0.61 cm; p = 0.38), but mean LA area was significantly smaller (16.7 ± 3.5 cm2v 18.9 ± 3.7 cm2; p < 0.001), with significant correlations between the 2 modalities for both (r = 0.74, 0.74, respectively; all p < 0.001). CONCLUSION: This exploratory study supported the feasibility of TEE for assessing LA longitudinal strain. There was an excellent correlation between atrial strain derived via TEE versus TTE, although values tended to be smaller on TEE, and bias between values was highly variable, suggesting that the values were not interchangeable.

Achondroplasia is a rare genetic disorder with multiple anatomic abnormalities making surgery, and anesthesia more challenging. The reported cases of cardiac interventions in this population are few, and to the best of our knowledge, only 16 cases are documented. Herein, we represent the first case of mitral and tricuspid repair in one of these patients, which performed without the need for specific equipment with a smooth postoperative course.

INTRODUCTION: Despite the significant clinical importance of sex among factors affecting cancer progression and survival, it remains one of the least studied factors. Therefore, we sought to examine these differences in relation to primary malignant cardiac tumors (PMCTs) using a national data set. METHODS: The 2004-2017 National Cancer Database was queried for patients with PMCTs. Annual trend of females' percent was assessed. Overall survival predictors were evaluated with Kaplan-Meier and Cox-regression. Subgroup analysis was done based on histology, comorbidity index, race, insurance, and surgical treatment. RESULTS: PMCTs were identified in 736 patients (median age 52, female [47.8%]). Most of them were high-grade (49.2%). About 60% underwent surgery. Angiosarcoma (43%), fibrosarcoma (5.2%), and leiomyosarcoma (5.2%) were the most common pathologies. Based on multivariate Cox-regression, higher income, higher comorbidity index, angiosarcoma, and Stage III/IV were associated with higher late mortality, while year of diagnosis and use of surgery or chemotherapy were associated with lower mortality. Among the surgical group, age, higher income, higher comorbidity index, angiosarcoma, and Stage III/IV were independent predictors of higher late mortality, while private insurance and year of diagnosis were associated with lower late mortality. No difference was seen between males and females in 30-day and late mortality (p = .71). Subgroup analysis based on Cox-regression showed no differences in late mortality between males and females. CONCLUSION: PMCTs have poor overall survival. Surgery and chemotherapy were associated with longer survival benefits. On the contrary, the associated risk factors for mortality were advanced age, higher comorbidity index, angiosarcoma histology, and Stage III/IV.

BACKGROUND: Saphenous vein grafts (SVG) are the most commonly used conduits in coronary artery bypass grafting (CABG). Graft failure is observed in up to 50% of SVG at 10 years after surgery. Whether a difference in SVG patency rates exists between men and women remains unclear. METHODS: We performed a study-level meta-analysis to evaluate sex-related differences in follow-up patency rates of SVG after CABG. A systematic literature search was conducted to identify studies on CABG that reported follow-up SVG patency rates in men and women. The primary outcome was SVG patency rates by sex at follow-up. RESULTS: Seventeen studies totaling 8235 patients and 14,781 SVG grafts were included. There was no significant difference in follow-up SVG patency rates between men and women (incidence rate ratio 0.96, 95% confidence interval 0.90-1.03, p = .24), with mean angiographic follow-up of 33.5 months (standard deviation 29.2). Leave-one-out and cumulative analysis were consistent with the main analysis. We concluded that follow-up SVG patency rate is similar between men and women undergoing CABG.

BACKGROUND: Racial minorities account for 39.9% of the population in the United States, but are often underrepresented in clinical research. Results from studies predominantly enrolling White patients may not apply to racial minorities. The aim of this analysis is to assess the representation of racial minorities in cardiac surgery randomized clinical trials (RCTs). METHODS: A systematic search of the literature was performed. All RCTs published from 2000 to 2020 including at least 100 patients and comparing two or more adult cardiac surgery procedures were included. Meta-analytic estimates were calculated. RESULTS: Among 51 cardiac surgery RCTs published between 2000 and 2020, only 9 (17.6%) reported the race of patients and were included in the final analysis. All of them were multicentric, with a mean of 33 centers included. Six RCTs enrolled patients undergoing coronary artery bypass grafting (66.7%), while the remaining three were on valve surgery (33.3%). Overall, 9193 patients were included; of them, 8034 (87.4%) were White and 1026 (11.2%) nonWhite (386 [4.2%] Black, 191 [2.1%] Hispanic, 274 [3.0%] from other races, and 175 [1.9%] nonWhite patients of unspecified race). The proportion of nonWhite patients did not change over time. CONCLUSIONS: Only 9 (17.6%) of the 51 cardiac surgery RCTs published between 2000 and 2020 reported the race of the patients enrolled and only 11.2% of them were nonWhite patients. Given the association between race and clinical outcomes, future RCTs should either guarantee a balanced inclusion of racial minorities or be designed to specifically enroll them.

BACKGROUND AND AIM: An open two-stage elephant trunk (ET) technique may aid in the technical ease of subsequent thoracoabdominal aortic aneurysm (TAAA) repair. We analyze whether the presence of an ET improves outcomes for patients undergoing extent I and II TAAA repair. METHODS: From September 1997 to October 2020, 469 patients underwent extent I or II TAAA repair. We compared those with prior ET to those without. Primary outcome was composite major adverse events (MAE) including operative mortality, myocardial infarction, permanent spinal cord injury, cerebrovascular accident, need for tracheostomy, and new need for dialysis. RESULTS: Thirty-eight (8.1%) patients had prior ET and 431 (91.9%) did not. There were no differences in baseline characteristics. The no ET group was more likely to undergo urgent or emergent procedures. Composite MAE occurred in 82 (19%) of the no ET group and 5 (15.8%) of the ET group (p = .785). Operative mortality was 5.5% and not significantly different between the groups (p = 1.00). No patients in the ET group experienced stroke or recurrent laryngeal nerve injury. Median partial bypass and cross-clamp times were significantly greater in the no ET group (28 [24-32] versus 19 [16-22] min; p ≤ .001 and 42 [32-53] versus 30 [25-39] min; p ≤ .001). CONCLUSIONS: Extent I and II TAAA repair after ET can be safely performed in a tertiary referral center with shorter bypass and cross-clamp times. ET eliminates the need for circulatory arrest or clamping a hostile arch.

OBJECTIVE: To investigate the impact of concomitant mitral valve repair (MVr) or replacement (MVR) at the time of aortic root replacement (ARR). METHODS: We queried our aortic database for consecutive patients undergoing ARR in combination with MVr or MVR from 1997 to 2021. Patients undergoing valve sparing root replacement (VSRR) were excluded. We compared operative mortality (OM) and a composite of major adverse events (MAE) in those undergoing CVG both with (Group 2) and without a concomitant MV procedure (Group 1). We also analyzed outcomes between patients undergoing MV repair versus MV replacement. RESULTS: Sixty-one patients underwent ARR with concomitant MVr (29/47.5%) or MVR (32/52.5%). Compared to patients in Group 2 (n = 955), those in Group 1 presented with worse NYHA class, lower ejection fraction, higher rate of connective tissue disease, and underwent more frequently urgent/emergent procedures. Group 1 had higher incidence of postoperative MAE (8/61(13%) vs 51/955(5%), p = .03). There was no difference in operative mortality between the two groups (0/61(0%) vs. 3/955(0.3%), p = 1). Compared to the ARR + MVR subgroup, the ARR + MVr subgroup had higher incidence of postoperative MAE (5/29(17.2%) vs. 3/32(9.4%), p = 0.02). Multivariate analysis identified MVr (OR 2.78, 95% confidence interval [CI] [1.03;7.48], p = 0.04) as an independent predictor of MAE. CONCLUSIONS: Operative mortality remained low in both groups. The addition of MVR/MVr to composite valve-graft replacement of the aortic root does not increase OM in experienced hands. The incidence of MAEs was higher in those undergoing MVr but may be a reflection of greater preoperative comorbidity rather than issues related to a more complex operation.

AIMS: Data suggest that women have worse outcomes than men after coronary artery bypass grafting (CABG), but results have been inconsistent across studies. Due to the large differences in baseline characteristics between sexes, suboptimal risk adjustment due to low-quality data may be the reason for the observed differences. To overcome this limitation, we undertook a systematic review and pooled analysis of high-quality individual patient data from large CABG trials to compare the adjusted outcomes of women and men. METHODS AND RESULTS: The primary outcome was a composite of all-cause mortality, myocardial infarction (MI), stroke, and repeat revascularization (major adverse cardiac and cerebrovascular events, MACCE). The secondary outcome was all-cause mortality. Multivariable mixed-effect Cox regression was used. Four trials involving 13 193 patients (10 479 males; 2714 females) were included. Over 5 years of follow-up, women had a significantly higher risk of MACCE [adjusted hazard ratio (HR) 1.12, 95% confidence interval (CI) 1.04-1.21; P = 0.004] but similar mortality (adjusted HR 1.03, 95% CI 0.94-1.14; P = 0.51) compared to men. Women had higher incidence of MI (adjusted HR 1.30, 95% CI 1.11-1.52) and repeat revascularization (adjusted HR 1.22, 95% CI 1.04-1.43) but not stroke (adjusted HR 1.17, 95% CI 0.90-1.52). The difference in MACCE between sexes was not significant in patients 75 years and older. The use of off-pump surgery and multiple arterial grafting did not modify the difference between sexes. CONCLUSIONS: Women have worse outcomes than men in the first 5 years after CABG. This difference is not significant in patients aged over 75 years and is not affected by the surgical technique.

BACKGROUND AND AIM: Aortic branch malperfusion complicates up to one-third of acute type A aortic dissection (ATAAD), and it is a strong predictor of poor outcomes. We analyzed our results for the surgical management of this high-risk cohort. METHODS: We queried our aortic database for consecutive patients undergoing ATAAD repair. Those presenting with malperfusion were compared with those without. Outcomes were compared using univariate and multivariate analysis. RESULTS: From 1997 to 2019, a total of 336 patients underwent ATAAD repair. A total of 97 ATAAD patients presented with malperfusion. Malperfusion patients were more likely to be male (54.8% vs. 75.3%; p = .001), have had a prior myocardial infarction (11.9% vs. 26.8%; p = .001), to present with preoperative renal dysfunction (22.2% vs. 54.6%; p < .001), and to present with shock (12.6% vs. 28.9%; p = .001). The malperfusion group more often underwent coronary artery bypass grafting (5.4% vs. 24.7%; p < .001), and required additional noncardiac procedures 10.3% of the time. Operative mortality (0.8% vs. 15.5%; p < .001) and major adverse events (MAEs) (7.6% vs. 20.6%; p = .001) were both greater for the malperfusion patients. Ejection fraction, diabetes, and malperfusion were predictors of MAEs. Cerebral, coronary, mesenteric, and multiple vascular bed malperfusion were predictors of MAEs, while extremity, renal, and spinal were not. CONCLUSION: Improving outcomes for this high-risk cohort requires rapid diagnosis and reversal of ischemia while minimizing the risk of aortic rupture, irrespective of the strategic approach.
