Abstract
OBJECTIVE Global Registry for Endovascular Aortic Treatment (GREAT) is an international prospective multicenter registry collecting real-world data on performance of W. L. Gore thoracic and abdominal aortic endografts. This analysis evaluated the long-term differences in patient survival and device performance in patients undergoing thoracic endovascular aortic repair (TEVAR) for any thoracic aortic pathology. METHODS From August 2010 to October 2016, 5014 patients were enrolled in GREAT. The population of interest was comprised of only patients treated for thoracic aortic pathologies. Through 5 years, primary outcomes were all-cause and aortic-related mortality, stroke, aortic rupture, endoleaks, migration, fracture, compression, paraplegia, and any reintervention through 5 years, grouped by pathology. Secondary outcomes were reintervention rate and freedom from serious device- and aortic-related events. RESULTS The 578 patients with thoracic aortic pathologies enrolled in GREAT and identified for this analysis were categorized by common pathologies: thoracic aneurysm (n = 239), thoracic dissection (n = 203), arch (n = 26), and other (n = 110). The mean age of this population was 66.1 ± 12.8 years, and 64.7% were male. Procedure survival was 99.7%. In the overall group, at index procedure to 30 days and 31 days to 5 years, Kaplan-Meier estimates of freedom from all-cause mortality were 99.6% and 66.4%, respectively, and for aortic-related mortality were 97.7% and 94.6%, respectively. Aortic rupture rate was 0.5% (n = 3) at 30 days and 1.4% (n = 8) through 5 years. Stroke and spinal cord ischemic events were 1.9% (n = 11) and 1.6% (n = 9) at 30 days and at 5 years were 3.6% (n = 20), 0.5% (n = 3), respectively. Reinterventions were required in 7.3% (n = 42) at 30 days and 12.4% (n = 69) through 5 years. The number of patients with endoleaks at 30 days was 2.1% (n = 12): n = 3 (1.1%) for each of types IA, 1B, and II; n = 2 (0.3%) for type III; and n = 4 (0.7%) for unspecified. Through 5 years, the percentage of patients was 8.3% (n = 40): n = 15 (3.1%) for type IA; n = 10 (2.1%) for type IB; n = 11 (2.3%) for type II; and n = 9 (1.9%) for unspecified. One patient (0.2%) had stent migration at 30 days (aneurysm group); none were reported through 5 years. There were no incidents of stent compression or fracture from index procedure through 5 years. CONCLUSIONS Data herein demonstrates durability and support for treatment of thoracic aortic disease with the GORE TAG conformable thoracic stent graft, including no incidents of stent compression/fracture and high freedom from aortic-related mortality. The planned analysis of follow-up to 10 years in GREAT will be beneficial.

Abstract
INTRODUCTION We undertook a systematic review of the currently published literature on TEVAR for DTAAs and we combined the eligible studies into a meta-analysis with the intention of evaluating the efficacy and the long-term durability of this treatment option. EVIDENCE ACQUISITION A systematic search of the literature from January 2015 up to December 2022 was performed according to the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. For events during follow-up we calculated the incidence rates (IRs) with 95% confidence intervals (95% CIs) per 100 patient-years (p-ys) as the number of patients with outcome events occurring during the specific time period divided by the total number of p-ys. EVIDENCE SYNTHESIS A total of 4127 study titles were identified by the initial search strategy, of which 12 were considered eligible for inclusion in the meta-analysis. A Total of 1976 patients (62% male) were identified among the eligible studies. One-year survival was 90.1% (95% CI 86.3% to 93.0%), 3-year survival was estimated at 80.5% (95% CI 69.2% to 88.4%) and the 5-year survival was estimated at 73.2% (95%CI 64.3% to 80.5%) with significant heterogeneity among studies regarding these outcomes. Regarding freedom from reintervention analysis for 1 year and 5 years was 96.5% (95% CI 94.5% to 97.8%) and 85.4% (95% CI 56.7% to 96.3%) respectively. The pooled late complications IR per 100 p-ys was 55.0 (95% CI 39.1 to 70.9), whereas the pooled IR for late reinterventions per 100 p-ys was 21.2 (95% CI 26.0 to 87.5). Late type I endoleak was reported with a pooled IR of 26.7 per 100 p-ys (95% CI 19.8 to 33.6) and late type III endoleak with a pooled IR of 7.6 per 100 p-ys (95% CI 5.5 to 9.7). CONCLUSIONS TEVAR presents a safe and feasible solution for the treatment of DTAA with sustained long-term effectivity. Current evidence supports a satisfactory 5-year survival with low rates of reinterventions.

Abstract
PURPOSE The objective of this systematic review was to report the cumulative incidence of endograft migration (EM), as well as the morbidity, reintervention rates, and mortality related to EM. This study aimed to provide evidence-based data on patient-relevant sequelae of EM after thoracic endovascular aortic repair (TEVAR) performed using contemporary aortic endografts. MATERIALS AND METHODS A systematic electronic search of literature in MEDLINE (via PubMed), Web of Science, and Cochrane Central Register of Controlled Trials was performed. The pooled synthesis of outcomes was performed using the inverse variance method. RESULTS Seven prospective non-randomized and 4 retrospective studies, including a total of 1783 patients presenting 70 EMs, were considered for the quantitative analysis. The pooled rate of EM was 4% (95% CI, 2%-7%; range, 0.2%-11%; I2=82%); pooled morbidity rate was 31% (95% CI, 12%-59%; range, 0%-100%; I2=64%) and pooled reintervention rate was 32% (95% CI, 15%-56%; range, 0%-100%; I2=55%). The pooled mortality rate due to EM was 5% (95% CI, 1%-21%; range, 0%-40%; I2=24%). CONCLUSION For the first time, this meta-analysis provides pooled reference estimates of EM after TEVAR. Thus, the results hold the potential to further characterize EM after TEVAR. The clinical relevance of EM is underlined by its association with high rates of endoleak-related morbidity, reintervention, and mortality. Close standardized surveillance after TEVAR for early detection of EM and prophylaxis of its sequelae is essential.

Abstract
PURPOSE In situ laser fenestration (ISLF) is a recently introduced technology that offers the potential to perform total endovascular treatment of aortic arch and thoracoabdominal aortic pathologies in the acute setting. This experiment's aim was to assess ISLF in some currently common aortic endografts and bridging stent-grafts. MATERIALS AND METHODS Three different aortic endografts were evaluated: (1) Zenith Alpha, (2) Zenith TX2, and (3) Conformable GORE TAG. Each endograft was submerged in 37°C saline to create fenestrations using the 308 nm CVX-300 Excimer Laser System fitted with a 2.3 mm diameter Turbo-Elite laser atherectomy catheter compatible with a 0.018″ guidewire. Three different 8 mm bridging stent-grafts were evaluated: (1) BeGraft peripheral, (2) BeGraft peripheral plus, and (3) GORE VIABAHN VBX Balloon Expandable. All bridging stent-grafts were deployed and exposed to different balloon sizes and pressures. The ISLFs and bridging stent-grafts were then evaluated for any tears, stenoses, and seal. RESULTS A laser fenestration was consistently rapidly obtained in the Zenith Alpha and the Zenith TX2 endografts while it proved difficult to achieve a timely fenestration in the C-TAG. No fabric tears were noted in the Zenith Alpha and Zenith TX2 when inflating Armada (Abbott) 8 mm balloon in the fenestrations with pressures up to 15 atmospheres (rated burst pressure) nor when flaring bridging stent-grafts with balloons up to 12 mm in diameter at 10 atmospheres, while major tears were frequently noted in the C-TAG when the Armada 8 mm balloons were inflated. BeGraft Peripheral and BeGraft Peripheral Plus were all firmly attached to the fenestrations showing good seal on manual testing, while every sixth VBX bridging stent-graft displayed poorer attachment to the fenestration before dilatation at high pressure. Commonly, significant stenoses remained in the bridging stent-grafts after dilatation at nominal pressure, which could only be eradicated with high-pressure balloons. CONCLUSION In this limited bench-test, Dacron endografts responded well to the ISLF technology. Satisfactory deployment of the bridging stent was noted only after inflation and/or flaring with high-pressure balloons. Further work with different types of commercially-available bridging stent-grafts and endografts to assess the durability of in situ fenestration (ISF) and bridging stents in ISF is recommended. CLINICAL IMPACT This report on experimental in situ laser fenestration provide important insights for clinicians considering using in situ laser fenestration of aortic stentgrafts in vivo. In particular, different laser settings were tested together with a selection of aortic stentgrafts. Also, the target pressure needed in PTA balloons to dilate the fenestrations and any subsequent tears in the fabric were noted. This was followed by deployment of assorted balloon-expandable stentgrafts with estimation of residual stenosis and seal.

Abstract
BACKGROUND Work relative value unit (wRVU) is a tool for assessing surgeons' performance, compensation, and productivity. It appears that wRVU for cardiovascular procedures does not consider complexity and its value for lengthy operations is low. The aim of the study is to determine wRVU for cardiovascular procedures in Iran according to the proposed approach. MATTERIALS AND METHODS This study was conducted as a mixed method in teaching hospitals in Tabriz in the period of September 2020 to December 2021. According to Hospital Information System and expert opinions, six procedures in cardiovascular surgery were included in the study. They were compared with 18 procedures in neurosurgery, orthopedics, and otorhinolaryngology in terms of the operation time and wRVU/min. Then, we calculated new wRVUs for the selected procedures based on surgeons' opinions, time measurements, and anesthetists' points of view by content analysis in qualitative and statistical analysis in quantitative parts. RESULTS Among the six cardiac procedures, the wRVU for five was under-estimated. The wRVU/min value ranged from 0/28 to 1/15 in the studied procedures. Findings demonstrate no significant relationship between the length of operations and the wRVU announced by the Ministry of Health and Medical Education (P value >0/05). Compared to studied procedures in four specialties, thoracoabdominal aortic aneurysm repair has the longest surgery time at 417 minutes. According to anesthesiologists, cardiovascular; orthopedics; ear, nose, and tongue; and neurosurgery specialties obtained 4/2, 2/9, 2/8, and 4, respectively, in terms of surgery duration, complexity, risk, and physical effort. CONCLUSION Despite policymakers' attempts to bring justice to payments, it seems that there has been little progress in paying cardiovascular surgeons. Improper payment to cardiovascular surgeons will affect the future of the workforce in this specialty. Today, the need to reconsider the wRVUs in heart specialty is felt more than before.

Abstract
The most important descending thoracic aortic (DTA) pathologies are aneurysms, dissections, and traumatic injuries. In acute settings, these conditions can constitute a significant risk of bleeding or ischemia of vital organs, resulting in a fatal outcome. Morbidity and mortality associated with aortic pathologies remain significant, despite improvements in medical therapy and endovascular techniques. In this narrative review, we present an overview of the transitions in the management of these pathologies and discuss current challenges and future perspectives. Diagnostic challenges include differentiating between thoracic aortic pathologies and cardiac diseases. Efforts have been made to identify a blood test that can rapidly differentiate these pathologies. Computed tomography is the cornerstone of diagnosing thoracic aortic emergencies. Our understanding of DTA pathologies has improved substantially due to the significant advancement in imaging modalities in the last 2 decades. On the basis of this understanding, the treatment of these pathologies has been revolutionized. Unfortunately, robust evidence from prospective and randomized studies is still lacking for the management of most DTA diseases. Medical management plays a crucial role in achieving early stability during these life-threatening emergencies. This includes intensive care monitoring, heart rate and blood pressure control, and considering permissive hypotension for patients presenting with ruptured aneurysms. Over the years, surgical management of DTA pathologies changed from open repair to endovascular repair with dedicated stent-grafts. Techniques in both spectrums have improved substantially.

Abstract
Although the management of traumatic injuries to the thoracic aorta has shifted toward endovascular management, the historical standard of care is open reconstruction. Choosing to reoperate when faced with a complication from a prior open repair can be challenging; endovascular management can be a reasonable option in this situation. This report describes a 54-year-old man with a remote history of open surgery for a traumatic injury to the descending thoracic aorta who underwent endovascular aortic stent graft placement for coverage of extrathoracic graft extension with pseudoaneurysm formation and distal embolization. He returned a year later with a type IIIb endoleak with rupture into the posterolateral chest wall. A sec ond endovascular approach was used to successfully reline the graft and exclude the rupture.

Outcomes of Endovascular Repair of Aortic Aneurysms with the GORE® Thoracic Branch Endoprosthesis for Left Subclavian Artery Preservation. J Vasc Surg 2022; 76:1141-1149.e3. [PMID: 35709864 DOI: 10.1016/j.jvs.2022.05.014] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 05/10/2022] [Accepted: 05/23/2022] [Indexed: 01/16/2023]
Abstract
OBJECTIVE OR BACKGROUND Thoracic endovascular aortic repair has emerged as the dominant paradigm for treatment of patients with descending thoracic aortic aneurysms. For aneurysms involving the aortic arch in the region of the left subclavian artery (LSA), branch vessel preservation to maintain blood flow to the LSA is recommended. Branched aortic endografts are an alternative to surgical revascularization of the LSA. METHODS Across 34 investigative sites, 84 patients with Zone 2 aneurysm were enrolled in a nonrandomized, prospective study of a single branched aortic endograft. The thoracic branch endoprosthesis device allows for graft placement proximal to the LSA and incorporates a single side branch for left subclavian perfusion. RESULTS Over half of the patients were male (63%). Their average age was 70 (±11) years. The aneurysm morphology was fusiform in 43 and saccular in 41 patients. The mean aneurysm diameter at screening was 56.2 mm. The mean follow up was 30 months (range 2.6 to 50.7 months). Reported here are the patient outcomes at 1 and 12 months. Pre-defined technical success with implantation of the device in landing Zone 2 was achieved in 92% (n=77) of patients. There were no cases of aortic rupture, lesion-related mortality, or new onset renal failure. There was no peri-operative (30-day) mortality. A single case each of permanent paraplegia and paraparesis occurred. Three patients experienced a procedure-related stroke. Through 12 months, four patients died; none of the deaths were adjudicated as related to the device or procedure. One aortic reintervention was required. A single case of aortic enlargement (core laboratory) was reported at 6 months. Type 1 (n=3) and III (n=5) endoleaks occurred in 9.8% of patients of which one (Type III) required reintervention. CONCLUSIONS Results from this device study in patients with Zone 2 aneurysm demonstrate that early safety and efficacy outcomes are maintained up to 12 months after the endovascular procedure with low mortality and reintervention rates and an acceptable frequency of procedural complications, including neurologic complications.
