Zhang Z, Driskill E, Chi J, Duensing I, Cui Q. Increased Rate of Complications Following Total Knee Arthroplasty in Patients Who Have Marfan Syndrome. J Arthroplasty 2024; 39:1726-1730. [PMID: 38211728 DOI: 10.1016/j.arth.2024.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 12/16/2023] [Accepted: 01/02/2024] [Indexed: 01/13/2024] Open
Abstract
BACKGROUND Outcomes of Marfan syndrome (MFS) patients after total knee arthroplasty (TKA) are poorly documented in the literature. The purpose of this study was to evaluate MFS as a potential risk factor for complications after TKA. METHODS Using a national private payer insurance database from 2010 to 2022, MFS patients undergoing primary TKA were identified and compared to 10:1 matched controls based on age, sex, obesity, diabetes mellitus, and a comorbidity index. A total of 4,092 patients undergoing primary TKA were analyzed, of which 372 had MFS. Multivariable logistic regression analyses were done for medical complications up to 90 days and surgical complications up to 2 years. 90-day emergency department-visits and inpatient readmissions were also documented. RESULTS Compared to the matched controls, patients who have MFS displayed elevated rates of surgical complications, including prosthetic instability (1-year, odds ratio (OR) 3.88, 95% confidence interval (CI) [1.58 to 8.66]; 2-year, OR 4.39, 95% CI [2.16 to 8.44]), and revision surgery (2 year, OR 1.79, 95% CI [1.05 to 2.91]). Additionally, patients who have MFS demonstrated significant higher rates of medical complications, including aortic dissection (2.15 versus 0%) and transfusion (OR 2.63, 95% CI [1.31 to 4.90]). CONCLUSIONS Patients who have MFS are at higher risks of postoperative complications after TKA, encompassing both medical and surgical complications. Specifically, patients who have MFS have a significantly higher likelihood of experiencing prosthetic instability and requiring revision surgery. Given these results, it is crucial for orthopedic surgeons and patients alike to consider these risks when determining a course of TKA for patients who have MFS.

Challenges in prompt identification and surgical correction of Marfan Syndrome aortic disease in a middle-income country: a case series study. J Cardiothorac Surg 2024; 19:323. [PMID: 38849906 PMCID: PMC11157853 DOI: 10.1186/s13019-024-02793-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Accepted: 05/18/2024] [Indexed: 06/09/2024] Open
Abstract
BACKGROUND Marfan Syndrome is an autosomal dominant disease caused by pathogenetic variants in the FBN1 gene. The progressive dilatation of the aorta and the potential risk of acute aortic syndromes influence the prognosis of these patients. We aim to describe population characteristics, long-term survival, and re-intervention patterns in patients who underwent aortic surgery with a previously confirmed clinical diagnosis of Marfan Syndrome in a middle-income country. METHODS A retrospective single-center case series study was conducted. All Marfan Syndrome patients who underwent aortic procedures from 2004 until 2021 were included. Qualitative variables were frequency-presented, while quantitative ones adopted mean ± standard deviation. A subgroup analysis between elective and emergent procedures was conducted. Kaplan-Meier plots depicted cumulative survival and re-intervention-free. Control appointments and government data tracked out-of-hospital mortality. RESULTS Fifty patients were identified. The mean age was 38.79 ± 14.41 years, with a male-to-female ratio of 2:1. Common comorbidities included aortic valve regurgitation (66%) and hypertension (50%). Aortic aneurysms were observed in 64% without dissection and 36% with dissection. Surgical procedures comprised elective (52%) and emergent cases (48%). The most common surgery performed was the David procedure (64%), and the Bentall procedure (14%). The in-hospital mortality rate was 4%. Complications included stroke (10%), and acute kidney injury (6%). The average follow-up was 8.88 ± 5.78 years. Survival rates at 5, 10, and 15 years were 89%, 73%, and 68%, respectively. Reintervention rates at 1, 2.5, and 5 years were 10%, 14%, and 17%, respectively. The emergent subgroup was younger (37.58 ± 14.49 years), had the largest number of Stanford A aortic dissections, presented hemodynamic instability (41.67%), and had a higher requirement of reinterventions in the first 5 years of follow-up (p = 0.030). CONCLUSION In our study, surveillance programs played a pivotal role in sustaining high survival rates and identifying re-intervention requirements. However, challenges persist, as 48% of the patients required emergent surgery. Despite not affecting survival rates, a greater requirement for reinterventions was observed, emphasizing the necessity of timely diagnosis. Enhanced educational initiatives for healthcare providers and increased patient involvement in follow-up programs are imperative to address these concerns.

Abstract
BACKGROUND Acute Type A aortic dissection (ATAAD) is a life-threatening cardiovascular disease associated with high mortality rates, where surgical intervention remains the primary life-saving treatment. However, the mortality rate for ATAAD operations continues to be alarmingly high. To address this critical issue, our study aimed to assess the correlation between preoperative laboratory examination, clinical imaging data, and postoperative mortality in ATAAD patients. Additionally, we sought to establish a reliable prediction model for evaluating the risk of postoperative death. METHODS In this study, a total of 384 patients with acute type A aortic dissection (ATAAD) who were admitted to the emergency department for surgical treatment were included. Based on preoperative laboratory examination and clinical imaging data of ATAAD patients, logistic analysis was used to obtain independent risk factors for postoperative in-hospital death. The survival prediction model was based on cox regression analysis and displayed as a nomogram. RESULTS Logistic analysis identified several independent risk factors for postoperative in-hospital death, including Marfan syndrome, previous cardiac surgery history, previous renal dialysis history, direct bilirubin, serum phosphorus, D-dimer, white blood cell, multiple aortic ruptures and age. A survival prediction model based on cox regression analysis was established and presented as a nomogram. The model exhibited good discrimination and significantly improved the prediction of death risk in ATAAD patients. CONCLUSIONS In this study, we developed a novel survival prediction model for acute type A aortic dissection based on preoperative clinical features. The model demonstrated good discriminatory power and improved accuracy in predicting the risk of death in ATAAD patients undergoing open surgery.

Abstract
OBJECTIVE The objective is to compare the characteristics of clinical data, imaging data, and treatment methods of young and old patients with acute type B aortic dissection (ABAD). METHODS ABAD patients admitted to the Department of Vascular Surgery of the First Affiliated Hospital of Anhui Medical University from January 2012 to December 2018 were retrospectively reviewed. Patient demographics, such as gender, age, diabetes, hypertension, presenting symptoms, imaging characteristics, laboratory data on admission, hemodynamics on admission and in-hospital management, and mortality of different age groups were compared and analyzed. Categorical variables were compared using χ2 tests or Fisher's exact test. Continuous variables were compared using Student's t-test or Mann-Whitney U-test. RESULTS A total of 141 ABAD patients were included in this study. Old ABAD patients were more likely to have a prior history of hypertension (88.6% vs 70.4%, p = 0.037) and atherosclerosis (29.8% vs 7.4%, p = 0.016). In the young group, Marfan syndrome was significantly higher (14.8% vs 0.9%; p = 0.005). Compared with the old group, the number of distal tears in the young group was significantly higher (62.3% vs 39.5%, p = 0.027). The proportion of patients with malperfusion of lower limbs in the young group was significantly higher than that in the old group (22.2% vs 6.1%, p = 0.026). There was no significant difference in the treatment methods and in-hospital mortality between the two groups. CONCLUSION Compared with old ABAD patients, young ABAD patients had more distal tears and a higher proportion of lower limbs malperfusion.

Abstract
BACKGROUND Marfan syndrome (MFS) is a genetic disorder caused by mutations in fibrillin-1 and is characterized by thoracic aortic aneurysms and other complications. Previous studies revealed sexual dimorphisms in formation of aortic aneurysm in patients with MFS. The current study aimed to investigate the combined role of a high-fat diet (HFD) and biological sex in aortic disease using the mgR/mgR MFS mouse model. METHODS Male and female mgR/mgR mice, as well as wild-type (WT) littermate mice, were fed a control diet (CD [10% fat]) or HFD (60% fat) from 4 to 12 weeks of age. Key aortic disease parameters analyzed included the diameter of the aortic wall; elastic fibre fragmentation; proteoglycan content; mRNA levels of Mmp12, Col1a1, Col3a1, and Fbn1; and fibrillin-1 deposition in the aortic wall. RESULTS HFD-fed female mgR/mgR mice had significantly reduced aortic diameters (35%), elastic fibre fragmentation (56%), pathologically enhanced proteoglycans (45%), and expression of Mmp12 (64%), Col1a1 (41%), and Col3a1 (43%) compared with male mgR/mgR mice on HFD. Fibrillin-1 deposition and Fbn1 mRNA levels were unaffected. The data reveal a protective effect of HFD in female mice. In contrast, CD did not exert any protective effects. CONCLUSIONS This study demonstrates a specific sexual dimorphism in MFS mice, with HFD exerting an explicit protective effect on severity of aortic disease in female mice. These preclinical data may be useful for developing nutritional recommendations for individuals with MFS in the longer term.

INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2023; 37:ivad128. [PMID: 37584655 PMCID: PMC10438956 DOI: 10.1093/icvts/ivad128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/01/2023] [Accepted: 08/14/2023] [Indexed: 08/17/2023]
Abstract
OBJECTIVES Marfan syndrome is a heritable connective tissue disorder with significant aortopathy and conveys substantial cardiovascular morbidity. This study characterizes the mortality and morbidities of thoracic aortic interventions (TAI) in the Marfan syndrome population in the state of Texas from 2009 to 2019. METHODS A retrospective review of the Texas Inpatient Discharge Dataset from 1 January 2009 to 31 December 2019. Discharges from acute care hospitals with a Marfan syndrome diagnosis by the International Classification of Diseases 9/10 codes and a procedure code for TAI were analysed utilizing descriptive, univariate and multivariable regression statistics. RESULTS There were 4641 Marfan syndrome discharges identified, of whom 644 (13.9%) underwent TAI. Thoracic or thoraco-abdominal aortic dissection or rupture was noted in 223 (34.6%). Thirty-three (5.1%) had a concomitant coronary artery intervention. There were 30 (4.7%) in-hospital mortalities, 126 (19.6%) diagnoses of acute renal failure (ARF), 52 (8.1%) had mechanical ventilation >96 h and the median length of stay was 10 [interquartile range (IQR) 7-16] days. After adjustment, concomitant coronary artery intervention was associated with in-hospital mortality [odds ratio (OR) 3.69 [IQR 1.15-11.90], P = 0.029] and ARF (OR 2.66 [IQR 1.19-5.94], P = 0.017). Aortic dissections/ruptures were associated with ARF (OR 1.73 [IQR 1.14-2.63], P = 0.010), ventilation >96 h (OR 2.19 [IQR 1.21-3.97], P = 0.010), and 15% longer length of stay (95% confidence interval 2.4-29.1%, P = 0.038). CONCLUSIONS TAI are frequent among the hospitalized Marfan Syndrome population. Concomitant coronary intervention is associated with increased risk of death and aortic dissections/ruptures are associated with increased morbidity. The high prevalence of aortic dissections/ruptures points to a potential target for improving imaging surveillance, adherence to treatment guidelines and preventative management of Marfan syndrome aortopathy.

Abstract
OBJECTIVE The International Registry of Acute Aortic Dissection (IRAD) celebrated its 25th anniversary in January 2021. This study evaluated IRAD's role in promoting the understanding and management of acute aortic dissection (AD) over these years. METHODS IRAD studies were identified, analyzed, and ranked according to their citations per year (c/y) to determine the most-cited IRAD studies and topics. A systematic search of the literature identified cardiovascular guidelines on the diagnosis and management of acute AD. Consequently, IRAD's presence and impact were quantified using these documents. RESULTS Ninety-seven IRAD studies were identified, of which 82 obtained more than 10 cumulative citations. The median c/y index was 7.33 (25th-75th percentile, 4.01-16.65). Forty-two studies had a greater than median c/y index and were considered most impactful. Of these studies, most investigated both type A and type B AD (n = 17, 40.5%) and short-term outcomes (n = 26, 61.9%). Nineteen guideline documents were identified from 26 cardiovascular societies located in Northern America, Europe, and Japan. Sixty-nine IRAD studies were cited by these guidelines, including 38 of the 42 most-impactful IRAD studies. Among them, partial thrombosis of the false lumen as a predictor of postdischarge mortality and aortic diameters as a predictor of type A occurrence were determined as most-impactful specific IRAD topics by their c/y index. CONCLUSIONS IRAD has had and continues to have an important role in providing observations, credible knowledge, and research questions to improve the outcomes of patients with acute AD.

Abstract
To the best of our knowledge, the present report is the first on the safety and efficacy of complete endovascular aortic reconstruction from zone 0 to 10 using a standardized approach and parallel stent graft configurations in high-risk patients considered unfit for surgery. During a 7-year period, five patients with complex thoracoabdominal aortic aneurysms and dissections involving zone 0-10 presented with rupture (n = 1; 20%), were symptomatic (n = 2; 40%), or had an aortic pseudoaneurysm (n = 2; 40%) and underwent complete endovascular zone 0-10 reconstruction using off-the-shelf stent grafts in parallel configurations that included chimneys, periscopes, and endovascular docking stations. The zone 0-5 complete arch chimney thoracic endovascular repair included chimneys that extended from the ascending thoracic aorta to the innominate, left common carotid, and left subclavian arteries and a thoracic stent graft extending from zone 0 to 5. The zone 5-10 aortic reconstructions were staged. Stage 1 included either thoracic stent graft and antegrade four visceral chimney placement or abdominal aortic stent graft and retrograde four visceral chimney placement. Stage II included completion of the remainder of the aortic reconstruction with cerebrospinal fluid drainage. A total of 15 aortic procedures included 34 chimneys (14 aortic arch and 20 visceral). Two patients (40%) underwent zone 0-5 aortic reconstruction first, and three patients (60%) underwent zone 5-10 aortic reconstruction first. The incidence of 30-day mortality, spinal cord ischemia, myocardial infarction, stroke, and visceral ischemia was 0%. At a mean follow-up of 4.5 ± 3.1 years, the aortic reconstruction-related mortality was 0%. All-cause mortality was 20%; one patient had died of pneumonia at 3 years postoperatively. Two endoleaks each occurred in zone 0-5 and zone 5-10 (40% for both groups). All endoleaks were treated with coil embolization. Complete endovascular zone 0-10 aortic reconstruction using parallel stent grafts with a docking station is a feasible and relatively safe technique that offers the ability to customize off-the-shelf devices for the treatment of high-risk patients with limited morbidity and mortality.

Abstract
Fibrillin-1 microfibrils are essential elements of the extracellular matrix serving as a scaffold for the deposition of elastin and endowing connective tissues with tensile strength and elasticity. Mutations in the fibrillin-1 gene (FBN1) are linked to Marfan syndrome (MFS), a systemic connective tissue disorder that, besides other heterogeneous symptoms, usually manifests in life-threatening aortic complications. The aortic involvement may be explained by a dysregulation of microfibrillar function and, conceivably, alterations in the microfibrils' supramolecular structure. Here, we present a nanoscale structural characterization of fibrillin-1 microfibrils isolated from two human aortic samples with different FBN1 gene mutations by using atomic force microscopy, and their comparison with microfibrillar assemblies purified from four non-MFS human aortic samples. Fibrillin-1 microfibrils displayed a characteristic "beads-on-a-string" appearance. The microfibrillar assemblies were investigated for bead geometry (height, length, and width), interbead region height, and periodicity. MFS fibrillin-1 microfibrils had a slightly higher mean bead height, but the bead length and width, as well as the interbead height, were significantly smaller in the MFS group. The mean periodicity varied around 50-52 nm among samples. The data suggest an overall thinner and presumably more frail structure for the MFS fibrillin-1 microfibrils, which may play a role in the development of MFS-related aortic symptomatology.

Abstract
INTRODUCTION The role of thoracic endovascular aortic repair (TEVAR) in patients with Marfan Syndrome with Stanford type B aortic dissection (TBAD) remains under debate. EVIDENCE ACQUISITION MEDLINE and EMBASE were searched through December 2021 to identify studies that investigated outcomes in MFS patients with TBAD who underwent TEVAR. Data regarding patient characteristics, perioperative and late outcomes were extracted. EVIDENCE SYNTHESIS Twelve studies were identified including 120 patients. The mean age was 40.2 years (95% confidence interval [CI], 36.8-43.6). 40.4% (95% CI: 10.8-70.0) of cases were performed emergently. 76.2% (95% CI: 64.6-87.8) of patients had a history of previous aortic surgery. In-hospital mortality was 3.7% (95% CI: 0.6-6.8). Primary endoleak occurred in 15.2% (95% CI: 8.6-21.8), which was comprised of type 1 (9.3% [95% CI: 3.9-14.6]) and type 2 (7.1% [95% CI: 2.3-12.0]) endoleaks. During mean follow-up period of 37.4 months (95% CI: 24.1-50.7), secondary endoleak was reported in 14.1% (95% CI: 7.1-21.1), which was comprised of type 1 (7.4% [95% CI: 2.4-12.5]) and type 2 (4.0% [95% CI: 0.3-7.7]) endoleak. Repeat TEVAR was performed in 15.5% (95% CI: 9.3-21.8) and open aortic surgery in 18.6% (95% CI: 9.6-27.5). Long-term mortality was 11.9% (95% CI: 6.5-17.3). CONCLUSIONS Our analysis showed that TEVAR for TBAD in patients with MFS has low perioperative morbidity and mortality but was associated with a high rate of late reintervention. This treatment option should be limited to emergent cases and to patients deemed unsuitable for open repair. Lifelong follow-up with imaging is mandatory in this population.

Abstract
Marfan syndrome is one of the most common inherited connective tissue disorders that affects the heart, eyes, blood vessels, and bones. It occurs in approximately 1-2 per 10,000 individuals annually. Many patients with Marfan syndrome eventually develop aortic wall abnormalities, often resulting in aortic dilatation, which increases the risk of acute aortic dissection. Recent studies involving SARS-CoV-2 propose that individuals with connective tissue disorders such as Marfan syndrome can have additional associated conditions that could impose a higher risk for morbidity and mortality from SARS-CoV-2. The purpose of this article is to discuss the interrelationship between Marfan Syndrome, Acute Type A Aortic Dissection in a patient with Sars-CoV-2 infection. Pertinent review of these conditions, diagnostic findings, treatment, and the patient's clinical course will be discussed. There is minimal research focused on the connection between this novel virus, Marfan Syndrome, and compounding risk for aortic dissection.

Abstract
The aorta is the largest artery in the body, delivering oxygenated blood from the left ventricle to all organs. Dissection of the aorta is a lethal condition caused by a tear in the intimal layer of the aorta, followed by blood loss within the aortic wall and separation of the layers to full dissection. The aorta can be affected by a wide range of causes including acute conditions such as trauma and mechanical damage; and genetic conditions such as arterial hypertension, dyslipidaemia, and connective tissue disorders; all increasing the risk of dissection. Both rapid diagnostic recognition and advanced multidisciplinary treatment are critical in managing aortic dissection patients. The treatment depends on the severity and location of the dissection. Open surgical repair is the gold standard of treatment for dissections located to the proximal part of the aorta and the arch, while endovascular interventions are recommended for most distal or type B aortic dissections. In this review article, we examine the epidemiology, pathophysiology, contemporary diagnoses, and management of aortic dissection.

Abstract
INTRODUCTION Connective tissue disorders predispose patients to earlier aortic dissections and aneurysms. However, there is limited large cohort data given its low incidence. METHODS The National Inpatient Sample was searched for all adults with Marfans (MFS) and Ehlers Danlos (EDS) disease between 2010 and 2017. ICD codes were used to select those with a type A aortic dissection or aneurysm. RESULTS There was a total of 19,567 cases, giving the estimated incidence of MFS and EDS of 18 and 22.4 per 100k people, respectively. After inclusion criteria, there were 2553 MF and 180 EDS patients. There was no statistical difference in mortality between the MFS and EDS cohorts (4.6% vs. 2.8%, p = .26). EDS patients were more likely to undergo a TEVAR procedure (2.8% vs. 1.0%, p = .03). MF patients were more likely to have a complication of acute kidney injury (p = .02). EDS patients were more likely older (50 vs. 42, p < .001) and female (47% vs. 33%, p < .001). MFS patients were more likely to have a type A aortic dissection (44% vs. 31%, p < .001). The majority (89%) of patients were treated at urban teaching hospitals. On univariable logistic regression, aortic dissection was a predictor for mortality (odds ratio 7.31, p < .001). The type of connective tissue disease was not a significant predictor. CONCLUSIONS National level estimates show low mortality for patients with MF or ED presenting to the hospital with aortic dissection or aneurysm. The differences in age and gender can guide surveillance for these patient populations, leading to more elective admissions and reduced hospital mortality.

Abstract
Aortopathy is a term most commonly used to describe a group of genetic diseases that predispose patients to an elevated risk of aortic events including aneurysm and acute aortic syndrome. Types of genetic aortopathy are classified as either heritable or congenital, with heritable thoracic aortic disease (HTAD) further subclassified into syndromic HTAD or nonsyndromic HTAD, the former of which is associated with specific phenotypic features. Radiologists may be the first physicians to encounter features of genetic aortopathy, either incidentally or at the time of an acute aortic event. Identifying patients with genetic aortopathy is of substantial importance to clinicians who manage thoracic aortic disease, because aortic diameter thresholds for surgical intervention are often lower than those for nongenetic aortopathy related to aging and hypertension. In addition, when reparative surgery is performed, the approach and extent of the repair may differ in patients with genetic aortopathy. The radiologist should also be familiar with competing diagnoses that can result in acute aortic events, mainly acquired inflammatory and noninflammatory thoracic aortic disease, because these conditions may be associated with increased risks of similar pathologic endpoints. Because many imaging and phenotypic features of various types of genetic aortopathy overlap, diagnosis and determination of appropriate follow-up recommendations can be challenging. A multidisciplinary approach with the use of imaging is often required and, once the diagnosis is made, imaging has additional importance because of the need for lifelong follow-up. ©RSNA, 2022.

Simple Death Risk Models to Predict In-hospital Outcomes in Acute Aortic Dissection in Emergency Department. Front Med (Lausanne) 2022; 9:890567. [PMID: 35677829 PMCID: PMC9168913 DOI: 10.3389/fmed.2022.890567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 04/08/2022] [Indexed: 11/24/2022] Open
Abstract
Objective We sought to find a bedside prognosis prediction model based on clinical and image parameters to determine the in-hospital outcomes of acute aortic dissection (AAD) in the emergency department. Methods Patients who presented with AAD from January 2010 to December 2019 were retrospectively recruited in our derivation cohort. Then we prospectively collected patients with AAD from January 2020 to December 2021 as the validation cohort. We collected the demographics, medical history, treatment options, and in-hospital outcomes. All enrolled patients underwent computed tomography angiography. The image data were systematically reviewed for anatomic criteria in a retrospective fashion by three professional radiologists. A series of radiological parameters, including the extent of dissection, the site of the intimal tear, entry tear diameter, aortic diameter at each level, maximum false lumen diameter, and presence of pericardial effusion were collected. Results Of the 449 patients in the derivation cohort, 345 (76.8%) were male, the mean age was 61 years, and 298 (66.4%) had a history of hypertension. Surgical repair was performed in 327 (72.8%) cases in the derivation cohort, and the overall crude in-hospital mortality of AAD was 10.9%. Multivariate logistic regression analysis showed that predictors of in-hospital mortality in AAD included age, Marfan syndrome, type A aortic dissection, surgical repair, and maximum false lumen diameter. A final prognostic model incorporating these five predictors showed good calibration and discrimination in the derivation and validation cohorts. As for type A aortic dissection, 3-level type A aortic dissection clinical prognosis score (3ADPS) including 5 clinical and image variables scored from −2 to 5 was established: (1) moderate risk of death if 3ADPS is <0; (2) high risk of death if 3ADPS is 1–2; (3) very high risk of death if 3ADPS is more than 3. The area under the receiver operator characteristic curves in the validation cohorts was 0.833 (95% CI, 0.700–0.967). Conclusion Age, Marfan syndrome, type A aortic dissection, surgical repair, and maximum false lumen diameter can significantly affect the in-hospital outcomes of AAD. And 3ADPS contributes to the prediction of in-hospital prognosis of type A aortic dissection rapidly and effectively. As multivariable risk prediction tools, the risk models were readily available for emergency doctors to predict in-hospital mortality of patients with AAD in extreme clinical risk.

Abstract
INTRODUCTION Acute-type aortic dissection (AD) during pregnancy is considered a rare and potentially fatal complication for both mother and fetus. Although the definite treatment for an acute-type AD is considered to be open-heart surgery, the decision to perform such a surgery during pregnancy requires a multidisciplinary approach and carries significant risks. METHODS In the present review of the literature, we have discussed various challenges in the management of acute-type AD during pregnancy, including therapeutic approaches, choosing the preferred imaging modalities, surgical techniques, and medication challenges. We have also reported an 8-week pregnant woman with Marfan syndrome who presented with chest pain and was diagnosed with acute AD. RESULTS The patient underwent a Bentall operation and was discharged in good condition with her fetus alive. The medical team's various decisions during preoperative, operative, and postoperative treatments were discussed. CONCLUSIONS Type A AD is considered infrequent in the second and third trimester of pregnancy and rare in the first trimester. Performing a CMR study without contrast in stable patients can help evaluate the extension of the flap. Urgent surgery in the hands of a skilled surgeon may prove lifesaving for the mother while maximizing the likelihood of preserving the fetus.

Abstract
All patients surviving an acute aortic dissection require continued lifelong surveillance of their diseased aorta. Late complications, driven predominantly by chronic false lumen degeneration and aneurysm formation, often require surgical, endovascular, or hybrid interventions to treat or prevent aortic rupture. Imaging plays a central role in the medical decision-making of patients with chronic aortic dissection. Accurate aortic diameter measurements and rigorous, systematic documentation of diameter changes over time with different imaging equipment and modalities pose a range of practical challenges in these complex patients. Currently, no guidelines or recommendations for imaging surveillance in patients with chronic aortic dissection exist. In this document, we present state-of-the-art imaging and measurement techniques for patients with chronic aortic dissection and clarify the need for standardized measurements and reporting for lifelong surveillance. We also examine the emerging role of imaging and computer simulations to predict aortic false lumen degeneration, remodeling, and biomechanical failure from morphological and hemodynamic features. These insights may improve risk stratification, individualize contemporary treatment options, and potentially aid in the conception of novel treatment strategies in the future.

Abstract
Genetic testing plays an increasing diagnostic and prognostic role in the management of patients with heritable thoracic aortic disease (HTAD). The identification of a specific variant can establish or confirm the diagnosis of syndromic HTAD, dictate extensive evaluation of the arterial tree in HTAD with known distal vasculature involvement and justify closer follow-up and earlier surgical intervention in HTAD with high risk of dissection of minimal or normal aortic size. Evolving phenotype–genotype correlations lead us towards more precise and individualized management and treatment of patients with HTAD. In this review, we present the latest evidence regarding the role of genetics in patients with HTAD.

Abstract
Strokes are the main cause of death and long-term disability worldwide. A stroke is a heterogeneous multi-factorial condition, caused by a combination of environmental and genetic factors. Monogenic disorders account for about 1% to 5% of all stroke cases. The most common single-gene diseases connected with strokes are cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) Fabry disease, mitochondrial myopathy, encephalopathy, lactacidosis, and stroke (MELAS) and a lot of single-gene diseases associated particularly with cerebral small-vessel disease, such as COL4A1 syndrome, cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL), and Hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS). In this article the clinical phenotype for the most important single-gene disorders associated with strokes are presented. The monogenic causes of a stroke are rare, but early diagnosis is important in order to provide appropriate therapy when available.

Abstract
Marfan syndrome (MFS) is a systemic connective tissue disorder that is inherited in an autosomal dominant pattern with variable penetrance. While clinically this disease manifests in many different ways, the most life-threatening manifestations are related to cardiovascular complications including mitral valve prolapse, aortic insufficiency, dilatation of the aortic root, and aortic dissection. In the past 30 years, research efforts have not only identified the genetic locus responsible but have begun to elucidate the molecular pathogenesis underlying this disorder, allowing for the development of seemingly rational therapeutic strategies for treating affected individuals. In spite of these advancements, the cardiovascular complications still remain as the most life-threatening clinical manifestations. The present chapter will focus on the pathophysiology and clinical treatment of Marfan syndrome, providing an updated overview of the recent advancements in molecular genetics research and clinical trials, with an emphasis on how this information can focus future efforts toward finding betters ways to detect, diagnose, and treat this devastating condition.

Abstract
Marfan syndrome (MFS) is an autosomal dominant, age-related but highly penetrant condition with substantial intrafamilial and interfamilial variability. MFS is caused by pathogenetic variants in FBN1, which encodes fibrillin-1, a major structural component of the extracellular matrix that provides support to connective tissues, particularly in arteries, the pericondrium and structures in the eye. Up to 25% of individuals with MFS have de novo variants. The most prominent manifestations of MFS are asymptomatic aortic root aneurysms, aortic dissections, dislocation of the ocular lens (ectopia lentis) and skeletal abnormalities that are characterized by overgrowth of the long bones. MFS is diagnosed based on the Ghent II nosology; genetic testing confirming the presence of a FBN1 pathogenetic variant is not always required for diagnosis but can help distinguish MFS from other heritable thoracic aortic disease syndromes that can present with skeletal features similar to those in MFS. Untreated aortic root aneurysms can progress to life-threatening acute aortic dissections. Management of MFS requires medical therapy to slow the rate of growth of aneurysms and decrease the risk of dissection. Routine surveillance with imaging techniques such as transthoracic echocardiography, CT or MRI is necessary to monitor aneurysm growth and determine when to perform prophylactic repair surgery to prevent an acute aortic dissection.

Abstract
BACKGROUND Guidelines for Sinus of Valsalva-thoracic aortic aneurysms (SOV-TAA) in Marfan syndrome recommend size-based criteria for elective surgical repair. Biomechanics may provide a better prediction of dissection risk than diameter. Our aim was to determine magnitudes of wall stress in the aortic root of Marfan patients using finite element analyses. METHODS Forty-six Marfan patients underwent patient-specific 3D SOV-TAA geometry reconstruction using imaging data. Finite element analyses were performed to determine wall stress distributions at SOV, sinotubular junction (STJ), and ascending aorta (AscAo) at systole. RESULTS Peak circumferential stresses were 432.8±111kPa, 408.1±88.3kPa, and 321.9±83.8kPa at the SOV, STJ, and AscAo, respectively with significant differences between SOV and AscAo (p<3.08E-07), and STJ and AscAo (p<2.26E-06). Peak longitudinal wall stresses were 352±73.9kPa, 277.5±89.5kPa, and 200.6±81kPa at SOV, STJ, and AscAo, respectively with significant differences between SOV and STJ (p< 6.01E-06), SOV and AscAo (p< 9.79E-13), and STJ and AscAo (p< 3.34E-07). Diameter was not correlated to wall stresses. Comparison of wall stresses in aneurysm <5cm vs ≥5cm and <4.5cm vs ≥4.5 showed no significant differences in wall stresses in the circumferential or longitudinal direction. CONCLUSIONS Peak wall stresses in Marfan SOV-TAA were greatest in SOV than STJ than AscAo. Diameter was poorly correlated to peak stresses such that current guidelines with 5cm cutoff had significant overlap in peak stresses in patients with <5cm vs ≥5cm. Use of patient-specific Marfan aneurysm models may identify patients with high wall stresses and small aneurysms who could benefit from earlier surgical repair to prevent aortic dissection.

Abstract
Background Due to the malfunction of connective tissue, Marfan patients are at increased risk of aortic dissection. Uncomplicated acute type B dissection is usually managed with medical therapy. Retrograde progression or new type A dissection is a relatively rare but often fatal complication that occur most frequently in the first 6 months after acute type B dissection. Case summary We present a 31-year-old male with Marfan syndrome and a recent uncomplicated type B dissection from the left subclavian to the right common iliac artery who underwent 4D flow magnetic resonance imaging (MRI). The dissection had a large proximal intimal tear just distal to the left subclavian artery (15 mm) and large false lumen (35 mm). Aortic blood flow just distal to the left subclavian artery (3.6 L/min) was split disproportionately into the true (0.8 L/min, 22%) and false lumen (2.8 L/min, 78%). 4D flow streamlines revealed vortical flow in the proximal false lumen. Increased wall shear stress was observed at the sinotubular junction (STJ), inner wall of the ascending aorta and around the subclavian artery. Two weeks after MRI, the patient presented with jaw pain. Computed tomography showed a type A dissection with an entry tear at the STJ for which an acute valve-sparing root, ascending and arch replacement was performed. Discussion Better risk assessment of life-threatening complications in uncomplicated type B dissections could improve treatment strategies in these patients. Our case demonstrates that besides clinical and morphological parameters, flow derived parameters could aid in improved risk assessment for retrograde progression from uncomplicated type B dissection to acute type A dissection.

Abstract
BACKGROUND Marfan syndrome (MFS) is a genetically determined systemic connective tissue disorder, caused by a mutation in the FBN1 gene. In MFS mainly the cardiovascular, musculoskeletal and ocular systems are affected. The most dangerous manifestation of MFS is aortic dissection, which needs to be prevented by a prophylactic aortic root replacement. MAIN BODY The indication criteria for the prophylactic procedure is currently based on aortic diameter, however aortic dissections below the threshold defined in the guidelines have been reported, highlighting the need for a more accurate risk stratification system to predict the occurrence of aortic complications. The aim of this review is to present the current knowledge on the possible predictors of severe cardiovascular manifestations in MFS patients, demonstrating the wide range of molecular and radiological differences between people with MFS and healthy individuals, and more importantly between MFS patients with and without advanced aortic manifestations. These differences originating from the underlying common molecular pathological processes can be assessed by laboratory (e.g. genetic testing) and imaging techniques to serve as biomarkers of severe aortic involvement. In this review we paid special attention to the rapidly expanding field of genotype-phenotype correlations for aortic features as by collecting and presenting the ever growing number of correlations, future perspectives for risk stratification can be outlined. CONCLUSIONS Data on promising biomarkers of severe aortic complications of MFS have been accumulating steadily. However, more unifying studies are required to further evaluate the applicability of the discussed predictors with the aim of improving the risk stratification and therefore the life expectancy and quality of life of MFS patients.

Clinical profiles and outcomes of acute type A aortic dissection and intramural hematoma in the current era: lessons from the first registry of aortic dissection in China. Chin Med J (Engl) 2021; 134:927-934.

Abstract
BACKGROUND Acute type A aortic dissection (ATAAD) and acute type A intramural hematoma (ATAIMH) are life-threatening diseases with high mortality. To better understand their clinical features in the Chinese population, we analyzed the data from the first Registry of Aortic Dissection in China (Sino-RAD) to promote the understanding and management of the diseases. METHODS All patients with ATAAD and ATAIMH enrolled in Sino-RAD from January 1, 2012 to December 31, 2016 were involved. The data of patients' selection, history, symptoms, management, outcomes, and postoperation complications were analyzed in the study. The continuous variables were compared using the Student's t test for normal distributions and the Mann-Whitney U test for non-normal distributions. Categorical variables were compared using the Chi-square test or Fisher exact test. RESULTS A total of 1582 patients with ATAAD and 130 patients with ATAIMH were included. The mean age of all patients was 48.4 years. Patients with ATAAD were significantly younger than patients with ATAIMH (48.9 years vs. 55.6 years, P < 0.001). For the total cohort, males were dominant, but the male ratio of patients with ATAAD was significantly higher compared to those with ATAIMH (P = 0.01). The time range from the onset of symptom to hospitalization was 2.0 days. More patients of ATAIMH had hypertension than that of ATAAD (82.3% vs. 67.6%, P < 0.05). Chest and back pain were the most common clinical symptoms. Computerized tomography (CT) was the most common initial diagnostic imaging modality. 84.7% received surgical treatment and in-hospital mortality was 5.3%. Patients with ATAAD mainly received surgical treatment (89.6%), while most patients with ATAIMH received medical treatment (39.2%) or endovascular repair (35.4%). CONCLUSIONS Our study suggests that doctors should comprehensively use clinical examination and genetic background screening for patients with ATAAD and ATAIMH and further shorten the time range from symptoms onset to intervention, achieving early diagnosis and treatment, thereby reducing the mortality rate of patients with aortic dissection in China. We should standardize the procedures of aortic dissection treatment and improve people's understanding. Meanwhile, the curing and transferring efficiency should also be improved.

Abstract
Patients with syndromic and nonsyndromic heritable aortopathies (also known as genetic aortic disease) are a heterogeneous group of patients who present at younger ages with more rapid growth of aortic aneurysms and/or increased frequency of dissections compared with patients with atherosclerotic aortopathies. In this review, we describe the etiology, epidemiology, and appropriate care delivery for these conditions at each stage of management. Within each section, we discuss sex, gender, and race differences and highlight disparities in care and knowledge. We then discuss the role of the vascular team throughout the cycle of care and the evolving inclusion of patient input in research. This understanding is essential to the creation of effective health care policies that support equitable, appropriate, and patient-centered clinical practices.

Abstract
The aorta is the 'greatest artery', through which oxygenated blood is delivered from the left ventricle to end organs with each cardiac cycle (200 million litres of blood transported in an average lifetime). The aorta can be affected by a wide spectrum of acute factors (such as cocaine use, weight lifting and trauma) and chronic acquired and/or genetic conditions (such as systemic arterial hypertension and phaeochromocytoma), which variously lead to increased aortic wall stress. The medial layer of the aorta can also be subject to abnormalities (such as Marfan syndrome, bicuspid aortic valve, inflammatory vasculitis, atherosclerosis and infections). Despite important advances in diagnostic and therapeutic interventions, data derived from registries and population-based studies highlight that the burden of aortic diseases remains high. Therefore, specific resources need to be allocated to design and implement preventive strategies (healthy lifestyles, modifications to cardiovascular risk factors, and educational and screening programmes) at individual and community levels. In this Review, we discuss the epidemiology, management and outcomes of the most common aortic diseases, namely, aortic aneurysms and acute aortic syndromes.

Abstract
Background Stanford type B aortic dissection is a rare, life-threatening complex phenotype associated with several modifiable and genetic risk factors. In the current study of a hospital-based, consecutive series of aortic dissection patients we propose a selection based on age and family history of aortic disease for genetic testing and detection of causative gene variants. Methods In this single center cohort study from 2013 to 2018 patients with acute Stanford type B aortic dissections were consecutively treated and analyzed by next generation sequencing based on selection criteria (age of disease onset ≤45 years and/or positive familial history for aortic disease) to detect genome-wide pathogenic variants in protein-coding sequences and to identify large copy number variants (CNV). Variants in a predefined panel of 30 genes associated with the familial thoracic aortic aneurysm and dissection (TAAD) syndrome were evaluated. Results From 105 patients nine matched selection criteria for genetic testing. Next-generation sequencing analysis revealed causal variants in FBN1 (fibrillin-1) in three patients: a pathogenic missense variant [c.6661T>C, p.(Cys2221Arg)] and two truncating variants [c.4786C>T, p.(Arg1596Ter)] and [c.6366C>CA, p.(Asp2123GlufsTer5)]. A fourth patient carried a large (>1,000,000 bp) CNV in the long arm of chromosome 10, deleting eleven genes, including the whole ACTA2 (actin alpha 2) gene. The latter two genetic findings have not been reported before. Conclusions Selection of patients on the basis of young age and familial inheritance of aortic disease favors the identification of disease-causing genetic variants in a clinical cohort of patients with Stanford type B aortic dissection.

Abstract
Background Marfan syndrome (MFS) is a systemic connective tissue disorder with life-threatening manifestations affecting the ascending aorta. MFS is caused by dominant negative (DN) and haploinsufficient (HI) mutations of the FBN1 gene. Our aim was to identify mutations of MFS patients with high detection rate and to investigate the use of a gene panel for patients with Marfanoid habitus. We also aimed to examine correlations between genotype and cardiovascular manifestations to predict “malignant” mutations.
Methods 136 individuals were enrolled. In the first phase, next-generation sequencing (NGS) and Sanger sequencing were performed for 57 patients to screen the FBN1 gene, followed by multiplex ligation-dependent probe amplification (MLPA) in negative cases. For repeated negative results, NGS gene panel involving 9 genes was used. In the second phase, 79 patients were tested primarily with the same gene panel, negative samples were tested by MLPA. Results 84 pathogenic mutations were detected, out of which 78 affected FBN1, 6 non-FBN1 mutations (2 TGFB2, 1 TGFBR2, 2 TGFBR1, 1 SMAD3) are associated with Loeys-Dietz syndrome (LDS). LDS patients had lower systemic score and they were younger, but their aortic involvement did not differ. MLPA detected 4 multi-exon deletions of FBN1 gene, which could not be identified by our first-step screening method. Aortic involvement (aortic dissection and/or dilation) did not differ significantly among HI and DN mutations (p = 0.061). Combined group of HI and DN mutations eliminating a disulphide-bonding cysteine (DN Cys) had significantly higher aortic involvement rate than DN mutations not eliminating a disulphide-bonding cysteine (DN non-Cys) (p < 0.001). Patients with DN Cys required significantly more aortic surgeries than HI and DN non-Cys mutations (p = 0.042 and p = 0.015, respectively). Conclusions Due to the relevant number of mutations affecting genes other than FBN1, preferred approach for testing individuals with Marfanoid habitus is using a gene panel rather than single-gene analysis, followed by MLPA for negative samples. DN Cys and HI mutations should be considered as risk factors for aortic involvement. Genetic testing for patients with Marfanoid features and a systemic score under 7 is recommended, as LDS patients may have lower scores, but they may have severe cardiovascular manifestations.

Abstract
Bicuspid aortic valve (BAV) is one of the most common congenital heart defects in children, adolescents and adults. BAV can occur as an isolated lesion or in association with other congenital heart defects, such as coarctation of the aorta or genetic syndromes like Turner syndrome. Although the majority of long term complications associated with BAV manifest later in life, children and adolescents may present with early onset valvular dysfunction or dilation of the aorta. BAV is a heterogeneous disease with a wide array of presentations at various ages, depending on the degree of aortic valve dysfunction, aortic dilation and presence of associated lesions. Aortic valve stenosis and/or regurgitation are the primary indications for intervention in children and adolescents with BAV. Although a majority of young patients with BAV also have some aortic dilation, interventions on the aorta are very rare during this time frame. Children and adolescents with BAV benefit from comprehensive assessment of their risk profile to determine follow-up surveillance intervals, sports recommendations, and timing of surgical intervention. The morphologic phenotype of BAV is important to identify, as it may predict future complications and prognosis.

Abstract
Background Marfan syndrome (MFS) is a genetically transmitted connective tissue disorder characterized by aortic root dilatation, dissection, and rupture. Molecularly, MFS pathological features have been shown to be driven by increased angiotensin II in the aortic wall. Using an angiotensin II-driven aneurysm mouse model, we have recently demonstrated that local inhibition of leptin activity restricts aneurysm formation in the ascending and abdominal aorta. As we observed de novo leptin synthesis in the ascending aortic aneurysm wall of patients with MFS, we hypothesized that local counteracting of leptin activity in MFS may also prevent aortic cardiovascular complications in this context. Methods and Results Fbn1C1039G/+ mice underwent periaortic application of low-dose leptin antagonist at the aortic root. Treatment abolished medial degeneration and prevented increase in aortic root diameter (P<0.001). High levels of leptin, transforming growth factor β1, Phosphorylated Small mothers against decapentaplegic 2, and angiotensin-converting enzyme 1 observed in saline-treated MFS mice were downregulated in leptin antagonist-treated animals (P<0.01, P<0.05, P<0.001, and P<0.001, respectively). Leptin and angiotensin-converting enzyme 1 expression levels in left ventricular cardiomyocytes were also decreased (P<0.001) and coincided with prevention of left ventricular hypertrophy and aortic and mitral valve leaflet thickening (P<0.01 and P<0.05, respectively) and systolic function preservation. Conclusions Local, periaortic application of leptin antagonist prevented aortic root dilatation and left ventricular valve remodeling, preserving left ventricular systolic function in an MFS mouse model. Our results suggest that local inhibition of leptin may constitute a novel, stand-alone approach to prevent MFS aortic root aneurysms and potentially other similar angiotensin II-driven aortic pathological features.

Abstract
This Society for Vascular Surgery/Society of Thoracic Surgeons (SVS/STS) document illustrates and defines the overall nomenclature associated with type B aortic dissection. The contents describe a new classification system for practical use and reporting that includes the aortic arch. Chronicity of aortic dissection is also defined along with nomenclature in patients with prior aortic repair and other aortic pathologic processes, such as intramural hematoma and penetrating atherosclerotic ulcer. Complicated vs uncomplicated dissections are clearly defined with a new high-risk grouping that will undoubtedly grow in reporting and controversy. Follow-up criteria are also discussed with nomenclature for false lumen status in addition to measurement criteria and definitions of aortic remodeling. Overall, the document provides a facile framework of language that will allow more granular discussions and reporting of aortic dissection in the future.
