Abstract
BACKGROUND Venous thromboembolism (VTE) incidence after thoracic and fenestrated endovascular aortic repair (TEVAR/FEVAR) is high (up to 6-7%) relative to other vascular procedures; however, the etiology for this discrepancy remains unknown. Notably, patients undergoing TEVAR/FEVAR commonly receive cerebrospinal fluid drains (CSFDs) for neuroprotection, requiring interruption of perioperative anticoagulation and prolonged immobility. We hypothesized that CSFDs are a risk factor for VTE after TEVAR/FEVAR. METHODS Consecutive TEVAR/FEVAR patients at a single center were reviewed (2011-2020). Cerebrospinal fluid drains (CSFDs) were placed based on surgeon preference preoperatively or for spinal cord ischemia (SCI) rescue therapy postoperatively. The primary end-point was VTE occurrence, defined as any new deep venous thrombosis (DVT) or pulmonary embolism (PE) confirmed on imaging within 30 days postoperatively. Routine postoperative VTE screening was not performed. Patients with and without VTE, and subjects with and without CSFDs were compared. Logistic regression was used to explore associations between VTE incidence and CSFD exposure. RESULTS Eight hundred ninety-seven patients underwent TEVAR/FEVAR and 43% (n = 387) received a CSFD at some point during their care (preoperative: 94% [n = 365/387]; postoperative SCI rescue therapy: 6% [n = 22/387]). CSFD patients were more likely to have previous aortic surgery (44% vs. 37%; P = 0.028) and received more postoperative blood products (780 vs. 405 mL; P = 0.005). The overall VTE incidence was 2.2% (n = 20). 70% (14) patients with VTE had DVT, 50% (10) had PE, and 20% (4) had DVT and PE. Among TEVAR/FEVAR patients with VTE, 65% (n = 13) were symptomatic. Most VTEs (90%, n = 18) were identified inhospital and the median time to diagnosis was 12.5 (interquartile range 7.5-18) days postoperatively. Patients with VTE were more likely to have nonelective surgery (95% vs. 41%; P < 0.001), had higher American Society of Anesthesiologists classification (4.1 vs. 3.7; P < 0.001), required longer intensive care unit admission (24 vs. 12 days; P < 0.001), and received more blood products (1,386 vs. 559 mL; P < 0.001). Venous thromboembolism (VTE) incidence was 1.8% in CSFD patients compared to 3.5% in non-CSFD patients (odds ratio 0.70 [95% confidence interval 0.28-1.78, P = 0.300). However, patients receiving CSFDs postoperatively for SCI rescue therapy had significantly greater VTE incidence (9.1% vs. 1.1%; P = 0.044). CONCLUSIONS CSFD placement was not associated with an increased risk of VTE in patients undergoing TEVAR/FEVAR. Venous thromboembolism (VTE) risk was greater in patients undergoing nonelective surgery and those with complicated perioperative courses. Venous thromboembolism (VTE) risk was greater in patients receiving therapeutic CSFDs compared to prophylactic CSFDs, highlighting the importance of careful patient selection for prophylactic CSFD placement.

Abstract
BACKGROUND The role of ACTA2 mutations in Familial Aortic Disease has been increasingly recognized. We describe a highly penetrant variant (R118Q) in a family with aortic disease. CASE REPORT A patient presented to us for elective repair of an ascending aortic aneurysm with a family history of his mother expiring after aortic dissection. Genetic testing revealed he was a heterozygous carrier of the ACTA2 missense mutation R118Q. Subsequently, all living family members were tested for this variant and a full medical history was obtained to compile a family tree for the variant and penetrance of an aortic event (defined as lifetime occurrence of aortic surgery / dissection). In total 9 family members were identified and underwent genetic testing with 7/9 showing presence of the ACTA2 R118Q mutation or an aortic event. All patients over the age of 50 (n = 4) had an aortic event. Those events occurred at ages 54, 55, 60, and 62 (mean event at 57.8 ± 3.9 years). Three family members with the variant under the age of 40 have not had an aortic event and most are undergoing regular aortic surveillance via CT scan. CONCLUSIONS Existing studies of known ACTA2 mutations describe a 76% aortic event rate by 85 years old. The R118Q missense mutation is a less common ACTA2 variant, estimated to be found in about 5% of patients with known mutations. Prior studies have predicted the R118Q mutation to have a slightly decreased risk of aortic events compared to other ACTA2 mutations. In this family, however, we demonstrate 100% penetrance of aortic disease above age 50. In today's era of excellent outcomes in elective aortic surgery, our team aggressively offers elective repair. We advocate for strict aortic surveillance for patients with this variant and would consider elective aortic replacement at 4.5 cm, or at an even smaller diameter in patients with a strong family history of dissection who are identified with this mutation.

Abstract
BACKGROUND Traditionally, acute uncomplicated type B aortic dissections are managed medically, and acute complicated dissections are managed surgically. Self-pay patients with medically managed acute uncomplicated type B aortic dissections may fare worse than their insured counterparts. METHODS In this single-center, retrospective cohort study, demographics, follow-up, and outcomes of patients with acute type B aortic dissections from 2011 to 2020 were analyzed. RESULTS In total, 159 patients presented with acute type B aortic dissections; 102 were complicated and managed with thoracic endovascular aortic repair, and 57 were uncomplicated and managed medically. A total of 32% (n = 51) were self-pay. Self-pay patients were from areas with worse area deprivation indices (71% vs 63%, P = .024). They more often reported alcohol abuse (28% vs 7%, P < .001), cocaine/methamphetamine use (16% vs 5%, P = .028), and nonadherence to home antihypertensives (35% vs 11%, P < .001). Self-pay patients less often had a primary care physician (65% vs 7%, P < .001) or took antihypertensives before admission (31% vs 58%, P = .003). Self-pay patients frequently required financial assistance at discharge (63%), most often using charity funds (46%). Few patients (7%) qualified for our hospital's financial assistance program, and most (78%) remained uninsured at the first follow-up. Self-pay acute uncomplicated type B aortic dissections patients had the lowest rate of follow-up (31% vs 66%, P < .001) and were more likely to represent emergently (75% vs 0%, P = .033) compared to insured acute uncomplicated type B aortic dissections patients. Self-pay patients were more likely to follow up after thoracic endovascular aortic repair for acute complicated type B aortic dissections (82% vs 31%, P < .001). CONCLUSION Self-pay patients have multiple, interconnected, complex socioeconomic factors that likely influence preadmission risk for dissection and post-discharge adherence to optimal medical management. Further research is needed to clarify treatment strategies in this high-risk group.

Abstract
BACKGROUND Endovascular repair of thoracoabdominal aortic aneurysms (TAAA) and juxtarenal aortic aneurysms (JAA) with fenestrated and/or branched endografts (B/FEVAR) has become common. Physician modified endografts for patients presenting with symptomatic or contained ruptures has made B/FEVAR a feasible option in nonelective settings. The purpose of this study was to describe our 10-year institutional experience with endovascular interventions for TAAA in elective and nonelective cases to evaluate differences in outcomes and the clinical risk factors associated with nonelective presentation. METHODS A prospectively maintained database was retrospectively queried for patients undergoing B/FEVAR for TAAA and JAA at a single tertiary care academic institution between 1/2011 and 12/2020. Data collected included demographics, comorbidities, presenting symptoms, aneurysm characteristics, and clinical outcomes. Nonelective repair was defined as any patient that presented through the Emergency Department, as a hospital transfer, or as a direct admission from clinic and had aortic repair performed during the same admission. Univariate analyses were used to compare patients. The primary outcomes were 30-day and 1-year mortality. Secondary outcomes included perioperative complications and nonhome discharge. RESULTS Between 1/201 and 12/2020, a total of 208 patients underwent B/FEVAR for TAAA (173) and JAA (35). Nonelective repair was performed in 44 (21%) patients with 39 for TAAA (23%) and 5 for JAA (14%). Nonelective patients were younger (71 ± 11 vs. 74 ± 7 years, P = 0.03), more likely to be self-pay or have Medicaid (11% vs. 2%, P = 0.02) and had a different race distribution compared to the elective cohort (P < 0.01). Thirty-day mortality was 4% (n = 6) in elective repairs and 7% (n = 3) in nonelective repairs. One-year mortality was 13% (n = 22) in elective repairs and 18% (n = 8) in nonelective repairs. There were no differences between patients receiving elective versus nonelective repair in 30-day (P = 0.40) or 1-year mortality (P = 0.47). Nonelective patients had longer median duration of stay (11 interquartile range (IQR) 6-15 vs. 5 IQR 4-8, P < 0.01), postoperative length of stay (7 IQR 5-12 vs. 4 IQR 3-7, P < 0.01), and more intensive care unit days (6 IQR 3-8 vs. 3 IQR 2-5, P < 0.01). There were no differences in other secondary outcomes between elective and nonelective patients including inpatient and access-related complications, re-interventions, and nonhome discharge (P > 0.05 for all comparisons). A composite "any complication" occurred more frequently in patients with nonelective repair (50% vs. 35%, P = 0.03). CONCLUSIONS Endovascular repair for TAAA or JAA is a good option in patients undergoing nonelective surgical intervention, with comparable 30-day mortality, 1-year mortality, and perioperative morbidity to that of patients undergoing elective B/FEVAR.

Abstract
OBJECTIVE Spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) can cause permanent neurologic deficits and poor long-term survival. Targeted treatment of new SCI symptoms after TEVAR (rescue therapy [RT]) might improve/resolve neurologic symptoms but few data characterize the association of specific interventions with SCI outcomes. We evaluated the effectiveness of post-TEVAR RT at our tertiary aortic center. METHODS Our institutional TEVAR database was reviewed for SCI incidence and details of RT. This included cerebrospinal fluid drainage (CSFD), medical therapy, and optimization of spinal cord oxygen delivery. SCI outcomes were categorized at discharge as paralysis/paraparesis and temporary/permanent. RESULTS Nine hundred forty-three TEVAR procedures were performed in 869 patients from 2011 to 2020. Post-TEVAR SCI occurred in 7.8% (n = 74) with permanent paraplegia in 1.5%. Older patient age, chronic obstructive pulmonary disease, and previous abdominal aortic surgery were predictive of SCI. Half (n = 37) of SCI episodes resulted in only temporary paralysis/paraparesis. Rescue postoperative cerebrospinal fluid drains were implanted in 3.7% (n = 35) of procedures and was predicted by higher American Society of Anesthesiologists class, lower serum hemoglobin level, elevated international normalized ratio, bilateral iliac artery occlusion, nonelective procedures, and penetrating atherosclerotic ulcer/intramural hematoma indication. The most commonly used RTs were emergent placement of or increased drainage from an existing cerebrospinal fluid drain (87.8%), induced/permissive hypertension (77.0%), corticosteroid bolus (36.5%), and naloxone infusion (33.8%). Neurologic improvement occurred in 68.9% (n = 51/74). New/increased drainage was associated with improved SCI outcome. CONCLUSIONS Permanent paraplegia from post-TEVAR SCI is rare (1.5%). Older patients with comorbidities carry greater post-TEVAR SCI risk. SCI symptoms improved/resolved with CSFD and multimodal RT in 68.9% of patients, but no intervention was independently associated with improvement. TEVAR centers should have robust protocols for timely and safe CSFD placement to augment RT strategies for SCI.

Abstract
Objective Spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) is associated with permanent neurologic deficit and decreased survival. Prophylactic cerebrospinal fluid (CSF) drainage (CSFD) in TEVAR is controversial. We evaluated the usage of CSFD in TEVAR at our tertiary aortic center. Methods Our institutional TEVAR database was reviewed to determine the frequency of CSFD usage/complications. Complications were categorized as mild (headache/CSF leak not requiring intervention, urinary retention), moderate (headache/CSF leak requiring intervention, drain malfunction requiring replacement), or severe (intrathecal hemorrhage, CSFD-attributable neurologic deficit). The relationships between CSFD complications and patient/procedural characteristics, CSFD placement timing, and survival were analyzed. Results Nine hundred thirty-six TEVAR procedures were performed in 869 patients from 2011 to 2020. Three hundred ninety CSFD drains were placed in 373 (41.7%) TEVAR patients. Most CSFD drains (89.5%) were pre-TEVAR. Most post-TEVAR drains were placed for new SCI symptoms (n = 21). Twenty-five patients (6.4%) suffered 32 CSFD complications. Most (n = 17) were mild in severity. Severe CSFD complications occurred in 5/432 (1.1% CSF drains) patients. No patient/procedural characteristics were predictive of CSFD complications. Post implant CSFD placement for new SCI symptoms conferred an increased risk of CSFD complication (odds ratio, 6.9; 95% CI, 2.42-19.6; P < .01). The long-term survival of the CSFD complication cohort did not differ from the overall population. Conclusions Post-TEVAR CSFD placement for new SCI symptoms was associated with substantially greater risk of CSFD complications. Avoidance of post-implant therapeutic drain placement might be the key to prevention of CSFD complications, favoring a strategy of selective pre-implant drain placement in patients at higher risk for SCI.

Abstract
Background The COVID‐19 pandemic has disrupted all aspects of healthcare, including cardiothoracic surgery (CTS). We sought to determine the pandemic's impact on CTS trainees' educational experiences. Methods A survey was developed and distributed to members of the Thoracic Surgery Residents Association and other international CTS trainees. Trainees were asked to evaluate their cumulative experiences and share their overall perceptions of how CTS training had been impacted during the earliest months of the COVID‐19 pandemic (i.e., since March 01, 2020). Surveys were distributed and responses were recorded June 25–August 05, 2020. In total, 748 surveys were distributed and 166 responses were received (overall response rate 22.2%). Of these, 126 of 166 responses (75.9%) met inclusion criteria for final analysis. Results Final responses analyzed included 45 of 126 (35.7%) United States (US) and 81 of 126 (64.3%) international trainees, including 101 of 126 (80.2%) senior and 25 of 126 (19.8%) junior trainees. Most respondents (76/126, 43.2%) lost over 1 week in the hospital due to the pandemic. Juniors (12/25, 48.0%) were more likely than seniors (20/101, 19.8%) to be reassigned to COVID‐19‐specific units (p < .01). Half of trainees (63/126) reported their case volumes were reduced by over 50%. US trainees (42/45, 93.3%) were more likely than international trainees (58/81, 71.6%) to report reduced operative case volumes (p < .01). Most trainees (104/126, 83%) believed their overall clinical acumen was not adversely impacted by the pandemic. Conclusions CTS trainees in the United States and abroad have been significantly impacted by the COVID‐19 pandemic, with time lost in the hospital, decreased operative experiences, less time on CTS services, and frequent reassignment to COVID‐19‐specific care settings.

Abstract
Coronary revascularization for multivessel disease remains a common and costly source of hospitalizations in the United States. Surgical techniques influence outcomes for coronary bypass and also affect the need for percutaneous coronary intervention in the future. As more radial access has been used for coronary angiography, consideration for use of the radial artery as a surgical conduit remains unclear. Saphenous vein grafts are commonly used for coronary bypass, however long-term patency remains suboptimal, and is also associated with a higher risk of adverse events with percutaneous coronary intervention. Thus, understanding the interplay between coronary bypass techniques and percutaneous coronary intervention has become increasingly important.

Abstract
OBJECTIVE We sought to examine the feasibility of a home practice curriculum of vascular anastomosis in cardiovascular surgery using a low-fidelity simulation platform and to examine its effectiveness in skill acquisition in senior surgical trainees. DESIGN We organized a multicenter prospective randomized study of senior residents and fellows, who were oriented to a low-fidelity cardiac simulator and an 8-week curriculum of independent practice of aortic and coronary anastomosis. "Treatment" trainees received a simulator and the curriculum. Control trainees received only their usual operative experience. The groups then crossed over; all were studied for 16 weeks in total. Video skill assessments were captured at 0, 8, and 16 weeks and were scored by one blinded investigator using the Joint Council on Thoracic Surgery Education Assessment tool. A post-hoc survey was distributed to invited participants following study completion. SETTING University of Minnesota Department of Surgery, Mayo Clinic Department of Cardiovascular Surgery, and the University of Texas Health Science Center at Houston. Participants used the simulator in offices, call rooms, and their homes. PARTICIPANTS Program participation in the study was solicited through the Thoracic Education Cooperative Group. Four institutions expressed interest and a total of 29 trainees were invited to the study and randomized. Of these, 12 (38%) completed the curriculum and submitted the requisite 3 sets of videos (6 treatment, 6 control). All were senior residents and fellows in general and cardiothoracic surgery. RESULTS No significant differences were detected in assessment scores before and after the curriculum nor before or after the control period in the overall or postgraduate year-stratified populations. Participant case numbers during the study did not have a significant effect on assessment scores. Randomized participants reported strong interest in deliberate practice of technical skills but identified competing clinical and personal obligations and significant barriers to simulation. CONCLUSIONS Considerable variability in performance existed among participants who completed the study, but overall, the curriculum alone was insufficient to improve simulator Joint Council on Thoracic Surgery Education scores compared to those not undergoing the curriculum. Among senior residents and fellows, provision of a practice curriculum and simulator for repeated practice is feasible but clinical and personal responsibilities were barriers to repetitive practice.

Abstract
Background Alpha-1-antitrypsin (A1AT) deficiency (A1ATD) is characterized by accelerated degradation of lung function. We examined our experience with lung transplantation for chronic obstructive pulmonary disease (COPD) with and without A1ATD to compare survival and rates of postoperative surgical complications. Methods Patients with A1ATD and non-A1ATD COPD undergoing lung transplantation from 1988-2015 at our institution were analyzed. Complications were categorized into non-gastroenteritis gastrointestinal (GI), wound, airway, and reoperation for bleeding. Overall and complication-free survival were evaluated using Kaplan-Meier curves and Cox proportional hazards models. Results Three hundred and eighty-five patients underwent lung transplant for COPD (98 A1ATD). For A1ATD, 56.1% underwent single lung transplantation (80.6% for COPD). Early overall and complication-free survival was worse for A1ATD, but this trend reversed at longer follow up. Unadjusted estimated survival showed advantage for COPD at 90 days and 1 year, which attenuated by 5 years and reversed at 10 years (P<0.001). On adjusted analysis, A1ATD was associated with a trend toward lower complication-free survival at 90 days and 1 year, due partly to increased rates of post-transplant GI pathology, particularly in the era of the lung allocation score (LAS). Conclusions A1ATD lung recipients had worse short-term complication-free survival but improved long-term survival compared to COPD patients. A1ATD was associated with greater risk of new GI pathology after transplant. Close monitoring of A1ATD patients with timely evaluation of GI complaints after transplant is warranted.

Abstract
BACKGROUND Donor organs are often procured by junior staff in stressful, unfamiliar environments where a single adverse event can be catastrophic. A formalized checklist focused on preprocedural processes related to thoracic donor organ procurement could improve detection and prevention of near miss events. METHODS A checklist was developed centered on patient identifiers, organ compatibility and quality, and team readiness. It went through five cycles of feedback and revision using a panel of expert procurement surgeons. Educational in-service sessions were held on the use of the checklist as well as best organ assessment practices. Near miss events before the survey were tallied by retrospective review of 20 procurements, and near misses after checklist implementation were prospectively recorded. We implemented the checklist for 40 donor lung and heart procurements: 20 from Cleveland Clinic and 20 from the University of Minnesota. A final survey assessment was used to determine ease of use. RESULTS Nine near miss events were reported in 20 procurements before use of the checklist. Thirty-one near miss events of 40 organ procurements were identified and potentially prevented by the checklist. Eighty-seven percent of fellows found the checklist to be unobtrusive to work flow, and 100% believed its use should be mandatory. Mortality was the same before and after implementation of the checklist despite increased patient volumes. CONCLUSIONS Implementation of a simple checklist for use during thoracic organ procurement uncovered a substantial number of near miss events. A preprocedural checklist for all thoracic organ transplants in the United States and abroad is feasible and would likely reduce adverse events.

Abstract
BACKGROUND AND AIM OF THE STUDY While mattress sutures are commonly used to secure annuloplasty rings during mitral valve repair, the use of a flexible ring secured with a running polypropylene suture has recently been advocated. The study aim was to assess the separation tensions of semi-rigid and flexible rings using mattress and running suture techniques in an in-vitro static load model. METHODS Semi-rigid and flexible annuloplasty rings were sutured with either mattress or running sutures (RM, RR, FM, FR) in four groups, of eight hearts each. Twelve additional sutures were passed through the surfaces of each ring to fix the preparation to a testing machine. In a fifth (control) group the mattress sutures securing a flexible ring (FMS) were connected directly to the machine. Each preparation was subjected to progressive axially directed (base-apex) tension until ring-tissue separation occurred. RESULTS The first major decrease in tension (defined as > or = 10 N in < or = 1.5 s) typically occurred with the separation of at least three adjacent sutures. These starting tensions (N) were: FMS 117 +/- 32.6, RR 131.7 +/- 30.5, RM 137.4 +/- 35.3, FM 152.1 +/- 32.3, and FR 213.2 +/- 30.5. The magnitudes of tension decrease with separation (and percentage of starting tensions) were: FMS 25.4 (21.2%), RR 26.8 (17.6%), RM 28.9 (21.6%), FM 24.6 (17.6%), and FR 22.5 (10.8%). The FR group required more tension to separate than the other groups (p < 0.001), but had a lower magnitude of force drop at dehiscence. CONCLUSION Flexible rings secured with a running suture required more force to separate than other ring-suture combinations. The lower magnitude of force drop in this group indicated a better tension distribution than in the other groups. Semi-rigid rings separated with a lower force, and had larger drops in tension, regardless of the suture technique used.
