Safety-net hospitals provide essential services to vulnerable patients with complex medical and socioeconomic circumstances. We hypothesized that matched patients at safety-net hospitals and non-safety-net hospitals would have comparable outcomes, costs, and readmission rates after isolated surgical aortic valve replacement (AVR) or mitral valve replacement (MVR).The National Readmissions Database was queried to identify patients who underwent isolated AVR (n = 109 744) or MVR (n = 31 475) from 2016 to 2018. Safety-net burden was defined as the percentage of patients who were uninsured or insured with Medicaid, with hospitals in the top quartile designated as safety-net hospitals. After propensity score matching, outcomes for AVR and MVR at safety-net hospitals vs non-safety-net hospitals were compared.Overall, 17 925 AVRs (16%) and 5516 MVRs (18%) were performed at safety-net hospitals, and these patients had higher comorbidity rates, had lower socioeconomic status, and more frequently required urgent surgery. Observed inhospital mortality was similar between safety-net hospitals and non-safety-net hospitals (AVR 2.2% vs 2.1%, P = .4; MVR 4.8% vs 4.3%, P = .1). After matching, rates of inhospital mortality, major morbidity, and readmission were similar; however, safety-net hospitals had longer length of stay after AVR (7 vs 6 days, P = .001) and higher total cost after AVR ($49 015 vs $42 473, P.001) and MVR ($59 253 vs $52 392, P.001).Isolated surgical AVR and MVR are both performed at safety-net hospitals with outcomes comparable to those at non-safety-net hospitals, supporting efforts to expand access to these procedures for underserved populations. Investment in care coordination resources to reduce length of stay and curtail cost at safety-net hospitals is warranted.

Background Differences in left ventricular mass regression (LVMR) between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) have not been studied. We present clinical and echocardiographic data from veterans who underwent TAVR and SAVR, evaluating the degree of LVMR and its association with survival. Methods We retrospectively reviewed TAVR (n = 194) and SAVR (n = 365) procedures performed in veterans from 2011 to 2019. After 1:1 propensity matching, we evaluated mortality and secondary outcomes. Echocardiographic data (median follow-up 957 days, interquartile range 483-1652 days) were used to evaluate LVMR, its association with survival, and predictors of LVMR. Results There was no difference between SAVR and TAVR patients in mortality (for up to 8 years), stroke at 30 days, myocardial infarction, renal failure, prolonged ventilation, reoperation, or structural valve deterioration. SAVR patients (67.3% [101/150]) were more likely to have LVMR than TAVR patients (55.7% [44/79], p = 0.11). The magnitude of LVMR was greater for the SAVR patients (median = −23.3%) than for the TAVR patients (median = −17.8%, p = 0.062). SAVR patients with LVMR had a survival advantage over SAVR patients without LVMR (p = 0.016). However, LVMR was not associated with greater survival in TAVR patients (p = 0.248). Conclusions SAVR patients were more likely to have LVMR and had a greater magnitude of LVMR than TAVR patients. LVMR was associated with better survival in SAVR patients, but not in TAVR patients.

Recruiting and promoting women and racial/ethnic minorities could help enhance diversity and inclusion in the academic cardiothoracic (CT) surgery workforce. However, the demographics of trainees and faculty at US training programs have not yet been studied.Traditional, integrated (I-6), and fast-track (4+3) programs listed in the Accreditation Council for Graduate Medical Education (ACGME) public database were analyzed. Demographics of trainees and surgeons, including gender, race/ethnicity, subspecialty, and academic appointment (if applicable), were obtained from ACGME Data Resource Books, institutional websites, and public profiles. Chi-square and Cochran-Armitage trend tests were performed.In July 2020, 78 institutions had at least 1 CT surgery training program; 40 (51%) had only a traditional program, 20 (26%) traditional and I-6, 6 (8%) all 3 types of program, and 4 (5%) only I-6. The proportion of female trainees increased significantly from 2011 to 2019 (19% vs 24%, P.001), with female I-6 trainees outnumbering female traditional trainees since 2018. Significant increases by race/ethnicity were observed overall and by program type, notably for Asian and Hispanic individuals in I-6 programs and Black individuals in traditional programs. Finally, of the 1175 CT surgeons identified, 633 (54%) were adult cardiac surgeons, 360 (37%) assistant professors, 116 (10%) women, and 33 (3%) Black.The demographic landscape of CT surgery trainees and faculty across multiple training pathways reflects increasing representation by gender and race/ethnicity. However, we must continue to work toward equitable representation in the workforce to benefit the diverse patients we treat.

Investigations into readmissions after surgical repair of acute Stanford type A aortic dissection (TAAD) remain scarce. We analyzed potential risk factors for readmission after TAAD.The 2013 to 2014 US Nationwide Readmissions Database was queried for TAAD index hospitalizations and 90-day readmissions indicated by diagnostic and procedural codes. Multivariable analysis was completed to identify risk factors and the most common reasons for readmission.We identified 6975 patients (65% men; mean age, 60.0 ± 0.4 years) who underwent surgical repair for TAAD. Overall 2062 patients (29.6%) were readmitted within 90 days: 634 (30.7%) during the first 30 days and 1428 (69.3%) during days 31 through 90. Readmitted patients had a higher prevalence of chronic kidney disease at index admission (18.0% vs 11.6%, P = .002), greater overall index length of stay (17.8 ± 0.6 vs 15. 5 ± 0.4 days; P = .0003), and greater index hospitalization cost ($90,637 ± $2691 vs $80,082 ± $2091; P = .0003). Mortality during readmission was 3.6% (n = 74). Indications for readmission were most commonly cardiac (26.2%), infectious (17.8%), and pulmonary (11.7%). Multivariate analysis identified 2 independent risk factors for readmission: acute kidney injury (odds ratio, 1.49; 95% confidence interval, 1.24-1.78; P.0001) and an Elixhauser comorbidity index4 (odds ratio, 1.26; 95% confidence interval, 1.06-1.49; P = .009).After surgical repair of TAAD, approximately 30% of patients were readmitted within 90 days, two-thirds of them during the 31- to 90-day period. Targeted improvements in perioperative care and postdischarge follow-up of patients with multiple comorbidities could mitigate readmission rates. Efforts to reduce readmissions should be continued throughout the 90-day period.

Objective The reversed elephant trunk technique permits staged repair of extensive thoracic aortic aneurysm in patients whose distal (ie, descending thoracic and thoracoabdominal) aorta is symptomatic or disproportionately large compared with their proximal aorta (ie, ascending aorta and transverse aortic arch). We present our 23-year experience with the reversed elephant trunk approach. Methods Between 1994 and 2017, 94 patients (median age 62 [46-69] years) underwent stage 1 reversed elephant trunk repair of the distal aorta. Fifty-three patients (56%) had aortic dissection, and 31 patients (33%) had heritable thoracic aortic disease. Eighty-eight operations (94%) were Crawford extent I or II thoracoabdominal aortic repairs. Twenty-seven patients (29%) underwent subsequent stage 2 repair of the proximal aorta; 14 patients (52%) required redo median sternotomy. The median time between the stage 1 and 2 operations was 18.8 (4.8-69.3) months. Results The operative mortality was 10% (9/94) for stage 1 repairs and 4% (1/27) for stage 2 repairs; 1 patient with heritable thoracic aortic disease died after stage 1 repair (1/31, 3%), and 1 patient died after stage 2 repair (1/13, 8%). Two patients (2%) had ruptures after stage 1 repair; 1 resulted in death, and 1 precipitated emergency stage 2 repair. In total, 36 patients (38%) who survived stage 1 repair died before stage 2 reversed elephant trunk completion repair could be performed. Conclusions Managing extensive aortic aneurysm with the 2-stage reversed elephant trunk technique yields acceptable short-term outcomes. This technique is useful for the reversed elephant trunk in patients who require distal aortic repair before proximal repair and is particularly effective in patients with heritable thoracic aortic disease. The low number of patients returning for completion repair is concerning. Rigorous surveillance is needed.

Background We investigated the relationship of sex with clinical outcomes after proximal aortic (ascending and arch) operations, and whether sex-specific preoperative factors are associated with mortality. Methods Of 3745 patients who underwent elective, urgent, and emergency proximal aortic operations over a 20-year period, 1153 pairs of men and women were propensity-matched, and their early and long-term outcomes were compared. Kaplan-Meier survival analysis was used to estimate late survival. Results Women and men had similar operative mortality (9.1% vs 8.8%, P = .8), stroke (5.7% vs 5.6%, P = .9), and renal failure rates (7.0% vs 6.6%, P = .7). Thirty-day mortality was 7.5% vs 5.6% (P = .06), respectively. Results were less favorable for women than for men regarding respiratory failure (34.3% vs 29.2%, P=0.008) and intensive care unit length of stay (9.11 ± 11.9 vs 7.87 ± 12.48 days; P = .023). Long-term survival was not significantly different between women and men: 66.3% (95% confidence interval [CI] 62.8%-69.5%) vs 67.1% (95% CI 63.6%-70.4%) at 5 years, and 45.9% (95% CI 41.76%-50.0%) vs 46.2% (95% CI 41.7%-50.6%) at 10 years (P = .4). Preoperative factors including diabetes, prior stroke, prior renal insufficiency, and peripheral vascular disease were associated with operative mortality in men, whereas chronic obstructive pulmonary disease was the main risk factor in women. Conclusions No differences were seen between the sexes in life-changing adverse outcomes after ascending aortic and arch procedures, although specific preoperative variables were associated with specific adverse events. Recognizing differences in preoperative risk factors for mortality between the sexes may facilitate targeted preoperative assessment, preparation, and counseling.

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.

BACKGROUND: At present, the optimal management strategy for chronic type B aortic dissection (CTBAD) remains unknown, as equipoise remains regarding medical management versus endovascular treatment versus open surgery. However, the results over recent years of thoracic endovascular aortic repair (TEVAR) in CTBAD appear promising. The aim of this systematic review was to provide a comprehensive analysis of the available data reporting outcomes and survival rates for TEVAR in CTBAD. METHODS: Electronic searches of six databases were performed from inception to April 2021. All studies reporting outcomes, specifically 30-day mortality rates, for endovascular repair of CTBAD were identified. Relevant data were extracted, and a random-effects meta-analysis of proportions or means was performed to aggregate the data. Survival data were pooled using data derived from original Kaplan-Meier curves, which allows reconstruction of individual patient data. RESULTS: Forty-eight studies with 2,641 patients were identified. Early (

Approximately one-third of patients with acute Stanford type B or DeBakey type III aortic dissection (TBAD) will develop complications, including persistent symptoms, malperfusion, enlarging aneurysms and impending rupture. In these cases, TBAD becomes a surgical emergency that requires endovascular intervention to complement the medical therapy. The immediate goal of endovascular therapy is to reestablish flow to the true lumen, stabilize the aneurysm and prevent rupture. Long-term goals are the remodeling of the descending thoracic aorta and the prevention of further surgeries in the thoracoabdominal aorta. In this report, we describe our step-by-step endovascular approach to TBAD repair.

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.

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.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.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.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.

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.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.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.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.

Background: Open surgical repair of a failed valve-sparing aortic root replacement (VSARR) or stentless bioroot aortic root replacement (bio-ARR) entails significant operative risks. Whether valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is feasible in patients with a previous VSARR or stentless bio-ARR remains unclear, given lingering concerns about the ill-defined aortic annulus in these patients and the potential for coronary obstruction. We present our experience with patients who had a previous VSARR or stentless bio-ARR and underwent ViV-TAVR to repair a degenerated aortic valve with combined valvular disease, aortic insufficiency and aortic stenosis. Methods: In this retrospective data review, we identified and analyzed consecutive patients with a previous VSARR or stentless bio-ARR who underwent ViV-TAVR between December 1, 2014 and August 31, 2019. Results: ViV-TAVR was performed in twelve high-risk patients with previous VSARR or bio-ARR during the study period. Of these, seven received Medtronic Freestyle porcine stentless bioprosthetic aortic roots, three received homograft aortic roots, one underwent a Ross procedure and one underwent VSARR. ViV-TAVR restored satisfactory valve function in all patients, and technical success was 100%. No patient had more than mild regurgitation after implantation. No thirty-day mortality was seen. One patient had major bleeding after transapical access, one patient had a transient ischemic stroke, and one patient needed permanent pacemaker implantation. At a median last follow-up of 21.5 months (interquartile range, 9.0–69.0 months), all patients remained alive and had satisfactory valve function. Conclusions: In this study, ViV-TAVR was a clinically effective option for treating patients with a failed stentless bio-ARR or previous VSARR. Short-term and intermediate-term results after these procedures were favorable. These findings may have important implications for treating high-risk patients with structural aortic root deterioration and call for better transcatheter heart valves that are suitable for treating aortic insufficiency.

Background The current representation of female patients and racial and ethnic minorities in cardiovascular trials is unclear. We evaluated these groups’ inclusion in U.S. cardiovascular trials. Methods Using publicly available data from ClinicalTrials.gov , we evaluated cardiovascular trials pertaining to coronary artery bypass grafting (CABG), heart valve disease, aortic aneurysm, ventricular assist devices, and heart transplantation. This yielded 178 U.S. trials (159 completed, 19 active but not recruiting) started between September 1998 and May 2017, with 237,132 participants. To examine female patients’ and racial and ethnic minorities’ representation in these trials, we calculated participation-to-prevalence ratios (PPRs). Values of 0.8 to 1.2 reflect similar representation. Results All 178 trials reported sex distribution, whereas only 76 (42.7%) trials reported racial distribution and 52 (29.2%) trials reported ethnic (Hispanic vs non-Hispanic) distribution. Among all trials, participants were 28.3% female, 11.2% were Hispanic/Latino, 4.0% were African American, 10.4% were Asian, and 2.3% were other. The CABG PPR for female patients was 0.64, for Hispanic patients was 0.72, for African American patients was 0.28, and for Asian patients was 3.20. Between 2008-2012 and 2013-2017, the CABG PPR decreased for female patients (0.67→0.50) and African American patients (0.37→0.17) but increased for Hispanic patients (0.38→1.32) and Asian patients (3.51→4.57). Conclusions Participation in cardiovascular trials by female patients and minorities (except Asian patients) remains low. Given that inherent differences among the previously mentioned groups could affect outcomes, balance is clearly needed. The engagement of our surgical leadership, community, and industry to address these disparities is vitally important.

In this prospective US investigational device exemption trial, we assessed the safety and 1-year clinical outcomes of the Thoraflex Hybrid device (Terumo Aortic) for the frozen elephant trunk technique to repair the ascending aorta, aortic arch, and descending thoracic aorta.For the trial, which involved 12 US sites, 65 patients without rupture were recruited into the primary study group, and 9 patients were recruited into the rupture group. All patients underwent open surgical repair of the ascending aorta, aortic arch, and descending thoracic aorta in cases of aneurysm and/or dissection. The primary end point was freedom from major adverse events (MAE), defined as permanent stroke, permanent paraplegia/paraparesis, unanticipated aortic-related reoperation (excluding reoperation for bleeding), or all-cause mortality.In the primary study group, 2 patients were lost to follow-up at 1 year. Freedom from MAE at 1 year was 81% (51/63). Seven patients (11%) died (including 2 before 30 days or discharge), 3 patients (5%) suffered permanent stroke, and 3 (5%) developed permanent paraplegia/paraparesis. Twenty-six patients (41%) underwent planned extension procedures, including 22 endovascular procedures within a median of 122 (interquartile range, 64-156) days. In the aortic rupture group, 2 patients were lost to follow-up at 1 year. Freedom from MAE at 1 year was 71% (5/7). One patient (14%) died, 2 patients (29%) had permanent stroke, and none had permanent paraplegia/paraparesis. No extension procedures were performed in the rupture group.One-year results with the Thoraflex Hybrid device are acceptable. Long-term data are necessary to assess the durability of these repairs.

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.

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.

Background Chest radiation therapy (CRT) for malignant thoracic neoplasms is associated with development of valvular heart disease years later. As previous radiation exposure can complicate surgical treatment, transcatheter aortic valve replacement (TAVR) has emerged as an alternative. However, outcomes data are lacking for TAVR patients with a history of CRT. Methods We conducted a retrospective study of all patients who underwent a TAVR procedure at a single institution between September 2012 and November 2018. Among 1341 total patients, 50 had previous CRT. These were propensity-matched in a 1:2 ratio to 100 patients without history of CRT. Thirty-day adverse events were analyzed with generalized estimating equation models. Overall mortality was analyzed with stratified Cox regression modelling. Results Median clinical follow-up was 24 months (interquartile range [IQR], 12–44 months). There was no difference between CRT and non-CRT patients in overall mortality (hazard ratio [HR] 0.84 [0.37–1.90], P = 0.67), 30-day mortality (HR 3.1 [0.49–20.03], P = 0.23), or 30-day readmission rate (HR 1.0 [0.43–2.31], P = 1). There were no differences in the rates of most adverse events, but patients with CRT history had higher rates of postprocedural respiratory failure (HR 3.63 [1.32–10.02], P = 0.01) and permanent pacemaker implantation (HR 2.84 [1.15–7.01], P = 0.02). Conclusions For patients with aortic valve stenosis and previous CRT, TAVR is safe and effective, with outcomes similar to those in the general aortic stenosis population. Patients with history of CRT are more likely to have postprocedural respiratory failure and to require permanent pacemaker implantation.

- Abstract
BackgroundThe 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.MethodsA single-center retrospective study was conducted, including a total of 27 patients with LP and 33 patients with DCP after TAVI between November 2013 to May 2021. We compared baseline demographics, pacemaker indications, percent pacing, ejection fractions, and pacemaker related complication rates.ResultsLeading indications for pacemaker implant were complete heart block (74% LP, 73% DCP) and high degree atrioventricular block (26% LP, 21% DCP). No significant differences were observed between LP and DCP in device usage and ejection fraction at 1, 6, and 12 months. Within each pacemaker group, we did not observe a significant reduction in percent ventricular pacing or ejection fraction at follow up. Three DCP patients required rehospitalization for pocket related complications.ConclusionFrom this single-center study, TAVI patients appear to have comparable pacemaker usage and ejection fraction between LP and DCP groups, suggesting that LP may be a reasonable alternative where single ventricular pacing is indicated. Larger studies are required to validate these findings.

Mycotic aortic aneurysm and its associated complications are often catastrophic. In this study, we examined the early and late outcomes of surgical repair of mycotic aortic aneurysm at our center over the last 3 decades.We retrospectively reviewed our prospectively maintained aortic surgery database with supplemental adjudication of medical records. Aortic infection was confirmed through clinical, radiological, intraoperative, pathological, and treatment evidence.Seventy-five patients (median age, 68 years; interquartile range, 62-74) who underwent surgical repair of a mycotic aortic aneurysm between 1992 and 2021 were included. Almost all patients (n = 72; 96%) presented with symptoms, including 26 patients (35%) with rupture, and many underwent urgent or emergency repair (n = 64; 85%). Sixty-one patients underwent open repair, and 14 patients underwent hybrid or endovascular repair. Infection-specific adjunct techniques included rifampin-soaked grafts (n = 16), omental pedicle flaps (n = 21), and antibiotic irrigation catheters (n = 8). There were 15 early deaths (20%), including 10 of the 26 patients (38%) who presented with rupture; however, persistent stroke, paraplegia or paraparesis, and renal failure necessitating dialysis were uncommon (each5%). Almost all early survivors (52/60; 87%) were discharged with long-term antibiotic therapy. Estimated survival at 2, 6, and 10 years was 55.7% ± 5.8%, 39.0% ± 5.7%, and 26.9% ± 5.5%, respectively.A substantial proportion of patients with mycotic aortic aneurysm present with rupture and generally require urgent or emergency repair. Operative mortality and complications are common, especially for patients who present with rupture, and late survival is poor.

Executive Summary While the United States (US) population at large is rapidly diversifying, cardiothoracic surgery is among the least diverse specialties in terms of racial and gender diversity. Lack of diversity is detrimental to patient care, physician well-being, and the relevance of cardiothoracic surgery on our nation’s health. Recent events, including the coronavirus disease 2019 pandemic and the Black Lives Matter protests, have further accentuated the gross inequities that underrepresented minorities face in our country and have reignited conversations on how to address bias and systemic racism within our institutions. The field of cardiothoracic surgery has a responsibility to adopt a culture of diversity and inclusion. This kind of systemic change is daunting and overwhelming. With bias ubiquitously entangled with everyday experiences, it can be difficult to know where to start. The Society of Thoracic Surgeons Workforce on Diversity and Inclusion presents this approach for addressing diversity and inclusion in cardiothoracic surgery. This framework was adapted from a model developed by the National Institute on Minority Health and Health Disparities and includes information and recommendations generated from our literature review on diversity and inclusion. A MEDLINE search was conducted using keywords “diversity,” “inclusion,” and “surgery,” and approaches to diversity and inclusion were drawn from publications in medicine as well as non-healthcare fields. Recommendations were generated and approved by The Society of Thoracic Surgeons Executive Committee. We present an overarching framework that conceptualizes diversity and inclusion efforts in a series of concentric spheres of influence, from the global environment to the cardiothoracic community, institution, and the individual surgeon. This framework organizes the approach to diversity and inclusion, grouping interventions by level while maintaining a broader perspective of how each sphere is interconnected. We include the following key recommendations within the spheres of influence: 1. In the global environment, it is important to understand how cardiothoracic surgery compares to fields outside of surgery and medicine overall in diversity and inclusion, and cardiothoracic surgeons should look to and learn from advances in other professions. 2. Professional societies that represent the cardiothoracic community share a responsibility to prioritize specialty-wide action to improve diversity in membership, mentorship, leadership, and representation at annual meetings. 3. Each institution (including health systems, medical schools, and clinical departments/sections) must perform a self-assessment of diversity and implement program-specific strategies to achieve diversity goals. 4. Individual surgeons can create cultures of inclusion by assessing personal implicit biases and advocating for diversity and inclusion. It is important to note that each of the spheres of influence is interconnected. Interventions to improve diversity must be coordinated across spheres for concerted change. Altogether, this multilevel framework (global environment, cardiothoracic community, institution, and individual) offers an organized approach for cardiothoracic surgery to assess, improve, and sustain progress in diversity and inclusion.

Without surgical repair, acute type A aortic dissection (TAAD) is usually fatal. However, some patients survive without 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.During 1990-2021, 205 patients underwent repair of TAAD in the chronic phase (60 days after onset). The two 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 [IQR], 3-25 months). Kaplan-Meier and competing-risk analyses provided time-dependent outcomes.At the time of intervention, most patients had chronic symptoms (40%). 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 (7%) operative deaths, and 7 (3%) strokes persisted to the time of death or discharge. No patient had persistent paraplegia. Median follow-up was 5 years (IQR: 2-11). Five-year survival was 62% (95% CI: 55-69%), and the incidence of reoperation was 3% (95% CI: 0.4-5.2%). Patients with type I and type II dissection did not differ significantly in survival (P=.2).Durable repair can be achieved with reasonable operative risk. Treatment is individualized and is associated with low rates of persistent neurological complications. Despite differing operative approaches by DeBakey type, early and late outcomes were similar.

Crawford extent II repairs are the most extensive thoracoabdominal aortic aneurysm operations and pose the greatest risk of postoperative spinal cord deficit. We sought to examine spinal cord deficit after open extent II thoracoabdominal aortic aneurysm repair to identify predictors of the most serious type: persistent paraplegia or paraparesis.We included 1114 extent II thoracoabdominal aortic aneurysm repairs performed from 1991 to 2017. Intercostal/lumbar artery reattachment (n = 959, 86.1%) and cerebrospinal fluid drainage (n = 698, 62.7%) were used to mitigate the risk of postoperative spinal cord deficit. We used univariate and multivariable analyses to examine spinal cord deficit and identify predictors of persistent paraplegia or paraparesis, defined as paraplegia or paraparesis present at the time of early death or hospital discharge.Spinal cord deficit developed after 151 (13.6%) repairs: 86 (7.7%) cases of persistent paraplegia or paraparesis (51 paraplegia; 35 paraparesis) and 65 (6.1%) cases of transient paraplegia or paraparesis. Patients with spinal cord deficit were older (median 68 vs 65 years, P .001) and had more rupture (6.6% vs 2.2%, P = .002) and urgent/emergency repair (25.2% vs 16.9%, P = .01) than those without. Persistent paraplegia or paraparesis developed immediately in 47 patients (4.2%) and was delayed in 39 patients (3.5%). Urgent/emergency repair (relative risk ratio, 2.31; P = .002), coronary artery disease (relative risk ratio, 1.80, P = .01), and chronic symptoms (relative risk ratio, 1.76, P = .02) independently predicted persistent paraplegia or paraparesis. Reattaching intercostal/lumbar arteries (relative risk ratio, 0.38, P .001) and heritable disease (relative risk ratio, 0.36, P = .01) were protective. Early and late survival were poorer in those with persistent paraplegia or paraparesis than in those without.Spinal cord deficit after extent II thoracoabdominal aortic aneurysm repairs remains concerning; survival is worse in patients with persistent paraplegia or paraparesis. The complexity of spinal cord deficit and persistent paraplegia or paraparesis warrant further study.

Diversity within health care organizations has many proven benefits, yet women and other groups remain underrepresented in cardiothoracic surgery. We sought to explore responses from a Society of Thoracic Surgeons (STS) survey to identify myths and barriers for informing organizational strategies in the STS and cardiothoracic surgery. We performed a qualitative review of narrative survey responses within three domains surrounding diversity in cardiothoracic surgery: myths, barriers, and strategies for improvement. Common diversity myths included diversity as a pipeline problem (24%), diversity equated to exclusivity (21%), and diversity not supporting meritocracy (18%). The most frequent barrier code was perceived prejudice (22%). Suggested strategies toward improvement were culture change prioritizing diversity (22%) and training the leaders (14%). Notably, 15% of response codes reflected the belief that disparities do not exist; thus, the issue should not be prioritized by the organization. The results do not necessarily reflect the beliefs of most of the STS membership; nonetheless, they provide important insight critical to guide any efforts toward eliminating disparities within cardiothoracic surgery and improving the care of our patients.

Objective We determined the effect of antegrade stent delivery in the descending thoracic aorta on short- and mid-term clinical and imaging outcomes for patients who underwent repair of acute DeBakey type I aortic dissection. Methods Outcomes were evaluated for 178 patients who underwent acute type I aortic dissection between 2005 and 2016 (standard repair, n = 115 [64.6%]; antegrade stent delivery, n = 63 [35.4%]). Propensity score match and multivariable analyses were performed to assess outcomes. Results The stent and standard repair groups had similar rates of operative mortality (30-day or in-hospital) (12.7% vs 17.4%, P = .41), persistent stroke (6.3% vs 5.3%, P = .75), and persistent paraplegia/paraparesis (1.6% vs 0.9%, P = 1.0). Propensity score match analysis indicated that the operative mortality rate was higher in the standard repair group (P = .059), which the multivariable analysis confirmed. The persistent stroke rate was nonsignificantly higher in the stent group (P = .66). Persistent paraplegia/paraparesis rates were similar in both groups (P = 1.0), and the overall rates of spinal cord ischemia were nonsignificantly higher in the stent group (P = .18). During follow-up (mean duration, 4.6 ± 3.6 y), computed tomography showed that stented patients more often had remodeling of the descending thoracic aorta (P = .0002) and somewhat more often had remodeling of the thoracoabdominal aorta (P = .13). Stented patients also had fewer subsequent procedures (P = .25). The 3- and 5-year survivals were 73.3% ± 6.9% and 49.9% ± 7.6% in the matched stented group and 66.3% ± 9.4% and 41.6% ± 7.7% in the matched standard group, respectively (P = .015 for overall survival). Conclusions In the short term, antegrade stent delivery was associated with less operative mortality. In the mid-term, promising remodeling of the false lumen was seen in stented patients, as were (nonsignificantly) lower rates of subsequent procedures in the thoracoabdominal aorta. Mid-term survival was also greater in the stented patients.
