Ocular Involvement and Treatment Pattern in Korean Patients with Marfan Syndrome: A Population-Based Study.

PURPOSE: This study aimed to investigate the incidence and prevalence of, and treatment patterns for ocular complications in Korean patients with Marfan syndrome. METHODS: Incidence and prevalence of Marfan syndrome was calculated from 2010 to 2018, based on data from the Korean National Health Insurance Service (KNHIS). Diagnosis codes (for cataract, ectopia lentis, retinal detachment, etc.) and surgery reimbursement codes (lensectomy, phacoemulsification, buckling, vitrectomy, etc.) in the patients with Marfan syndrome were retrieved by complete enumeration of the data. RESULTS: The annual prevalence of Marfan syndrome adjusted by age and sex was gradually increased from 2.44 per 100,000 in 2010 to 4.36 per 100,000 in 2018. The age group of 10-19 years showed the highest prevalence. The prevalence of ectopia lentis was 21.7%, of whom 43.0% underwent surgeries. Surgery for RD was performed in 253 (14.1%) of 2044 patients during the study period. CONCLUSION: Although the most prevalent ophthalmologic manifestation was ectopia lentis, total prevalence rate of RD was more than 10% in the study period; thus, regular fundus examination is recommended for the patients with Marfan syndrome.

Prevalence of intracranial aneurysms in Marfan syndrome.

OBJECTIVE: Aneurysmal pathology of the aorta is well-defined in the Marfan syndrome (MFS) population. Owing in part to the rarity of pathologies, the prevalence of intracranial aneurysms (IA) in MFS is poorly defined. There is debate as to whether or not there is an association between the two. The aim of this study was to evaluate the prevalence of IA in a population of patients with MFS who underwent intracranial imaging. METHODS: This was a single-center retrospective review of patients with MFS. Between 1995 and 2021, 983 patients were reviewed. We identified 198 patients with MFS who had intracranial imaging. Imaging consisted of CTA and/or MRA, and was read by an attending radiologist. Details of the aneurysm, patient demographics, and aortic characteristics were collected. RESULTS: The prevalence of IA was 7.1% (14/198). Age of patients with IA (55.0 ± 15.1 years) was not significantly different than those without IA (52.6 ± 16.0 years) (P = .58). The most common location of IA was the internal carotid artery. The mean diameter of the IA was 7 ± 5.8 mm. No ruptures of the internal carotid artery were identified. One patient (0.5%) underwent intervention for the IA. There were no significant differences found in aortic characteristic including dimensions, history of dissection, or aneurysm. CONCLUSIONS: In a large, single-center experience over 20 years, we identified patients with confirmed MFS who underwent intracranial imaging. The prevalence of IA in our experience was 7.1%. There were no patient or aortic characteristics found to be significantly associated with IA; however, this finding may be due to the small number of aneurysms. Although this number is higher than the historically reported prevalence in the general population, a collection of experiences from multiple institutions will likely be required to truly define the risk of IA in MFS and to determine whether screening is warranted.

Ocular morbidity in Marfan syndrome: a nationwide epidemiological study.

BACKGROUND: Ophthalmic complications are profound in Marfan syndrome (MFS). However, the overall burden is not well described. Our purpose was to evaluate the ocular morbidity in a nationwide perspective. METHODS: We identified the ocular morbidity in patients with MFS (n=407) by use of Danish national healthcare registers, using number and timing of hospital contacts related to ophthalmic diagnoses, to ophthalmic surgery and to prescriptions for ophthalmic medication. An age-matched and gender-matched background population (n=40 700) was used as comparator. RESULTS: Among MFS, 56% (226/407) of the patients had at least one registration of an ophthalmic diagnosis as inpatient or outpatient during the study period (HR of 8.0 (95% CI 7.0 to 9.2)). Seven out of 11 main groups of diagnoses were affected, including 'Lens', 'Choroid and retina', 'Ocular muscles, binocular movement, accommodation and refraction', 'Glaucoma', Visual disturbances and blindness', 'Vitreous body and globe', and 'Sclera, cornea, iris and ciliary body'. The number of surgical procedures as well as the use of ophthalmic medication in patients with MFS was significantly increased. CONCLUSION: This nationwide epidemiological study of ocular morbidity in MFS demonstrates a profound burden and emphasises the need for thorough and experienced ophthalmological surveillance.

Thoracic and Thoracoabdominal Aneurysms: Etiology, Epidemiology, and Natural History.

Thoracic aortic aneurysms and thoracoabdominal aneurysms are often found incidentally. Complications include dissection or rupture. Most of the thoracic aortic aneurysms and thoracoabdominal aneurysms develop in patients with risk factors for atherosclerosis. Younger patients without significant cardiovascular risk factors may have a genetic basis and include syndromes such as Marfan, Ehlers-Danlos, and Loeys-Dietz and bicuspid aortic valve. Most thoracic aneurysms grow slowly over time and factors that accelerate growth rate include dissection, aneurysm size, bicuspid valve disease, and Marfan syndrome. Size cutoffs where complications occur determine when surgery or intervention should be considered.

A cross-sectional study on fatigue, anxiety, and symptoms of depression and their relation with medical status in adult patients with Marfan syndrome. Psychological consequences in Marfan syndrome.

Marfan syndrome (MFS) is a connective tissue disorder affecting the cardiovascular, ocular, and skeletal system, which may be accompanied by psychological features. This study aimed to determine the prevalence of fatigue, anxiety, and symptoms of depression in MFS patients, and to assess the degree to which sociodemographic and clinical variables are associated with fatigue and psychological aspects. The prevalence of fatigue, anxiety, and symptoms of depression were assessed in two cohorts of MFS patients and compared with healthy controls. The checklist individual strength (CIS), and hospital anxiety and depression scale (HADS) questionnaires were utilized. Medical status was assessed (family history of MFS, aortic root dilatation >40 mm, previous aortic surgery, aortic dissection, chronic pain, skeletal involvement, and scoliosis). Severe fatigue was experienced by 37% of the total MFS cohort (n = 155). MFS patients scored significantly higher on the CIS questionnaire, concerning severe fatigue, as compared with the general Dutch population (p < 0.0001). There were no differences in HADS anxiety or depression scores. In older MFS patients, with a more severe cardiovascular phenotype, chronic pain, and a higher unemployment rate, significantly more symptoms of depression were observed, when compared with the general population (p = 0.027) or compared with younger MFS patients (p = 0.026). Multivariate analysis, showed that anxiety was associated with chronic pain (p = 0.022) and symptoms of depression with unemployment (p = 0.024). MFS patients report significantly more severe fatigue as compared with the general population. Since the cause of fatigue is unclear, more research may be needed. Psychological intervention, for example, cognitive behavioral therapy, may contribute to a reduction in psychological symptoms.

Extrathoracic Aneurysms in Marfan Syndrome: A Systematic Review of the Literature.

BACKGROUND: Marfan syndrome (MS) most often shows as thoracic aortic aneurysm (TAA) or aortic dissection, but it may also involve other vascular territories. This study aimed to identify those extrathoracic vascular manifestations most frequently associated with MS. METHODS: A systematic review of the literature with Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria was carried out. The following databases were included: MEDLINE, Embase, Web of Science, Cumulative Index of Nursing and Health Sciences Literature (CINHAL); Spanish database MEDESY Cochrane Central Register of Controlled Trials (CENTRAL). RESULTS: A total of 10,008 articles were identified, leaving 155 for the first stage of data analysis (total incidence of aneurysms) and 83 for the second (descriptive data analysis). Overall, 518 aneurysms were identified: 149 in the head and neck, 94 in the extremities, and 275 in the aortic, iliac, and visceral sectors. Mostly, they were simultaneously discovered during studies of the TAA. In the abdominal aorta, the presentation with rupture in 11 of 32 patients stands out. Resection and bypass were the most frequently used methods for repair in the treated cases. CONCLUSIONS: Although its frequency in the general population is unknown, this systematic review suggests that extrathoracic aneurysmal arterial involvement in the MS may be more frequent than expected. We believe screening for aneurysms in other vascular sectors may be advisable, especially in patients with MS and TAA.

Prevalence of Periodontitis among Patients Diagnosed with Marfan Syndrome: A Cross-Sectional Study Comparing Samples of Healthy Patients.

Periodontitis is an inflammatory condition caused by a bacterial plaque and characterized by progressive destruction of the tooth-supporting apparatus. Patients with Marfan syndrome (MFS) exhibit a connective tissue disorder, which can also affect oral soft and hard tissue. Thus, the aims of this cross-sectional study were to assess the association between periodontitis and MFS and secondly, to compare periodontal parameters and prevalence of disease with a control group (CG) without MFS. 152 patients (MFS = 76, CG = 76) were recruited to evaluate the following periodontal parameters: probing depth, gingival margin, clinical attachment level, plaque index, and bleeding on probing. The 2017 World Workshop guideline was followed for the diagnosis of the periodontal status. A multivariate analysis was performed using a multinomial logistic regression adjusted for age, gender, and smoking. The level of significance required was p < 0.05. Patients with MFS did not show a higher prevalence of periodontitis compared to the CG. However, patients with MFS did have higher values in probing depth, gingival recession, clinical attachment level, and plaque index compared to the CG patients (p < 0.05). In conclusion, although similar prevalence of periodontitis was found among the studied groups, MFS patients showed worse periodontal parameters.

Prevalence and Outcomes of Primary Left Ventricular Dysfunction in Marfan Syndrome.

Even in the absence of significant valvular disease, patients with Marfan syndrome (MFS) have evidence of impaired left ventricular (LV) performance, suggestive of a primary cardiomyopathy. However, the true prevalence and long-term outcomes of this disease process remain largely unknown. We performed a retrospective analysis of all adult patients with confirmed MFS followed at Stanford Health Care. Those with significant valvular regurgitation, coronary artery disease, or previous cardiac surgery were excluded. LV systolic dysfunction was defined as a LV ejection fraction (LVEF) <55% on transthoracic echocardiography. A total of 753 patients with confirmed MFS were followed up over a median duration of 8 years (interquartile range 4 to 13). Of those, 241 patients (53% women, 71% White) met inclusion criteria and comprised the study cohort. LV systolic dysfunction was present in 30 patients (12%), with a median age of onset of 25 years (interquartile range 19 to 37), median EF of 52% (interquartile range 48 to 54), and evidence of clinical heart failure (New York Heart Association functional class ≥II) in 10% of patients. LV systolic dysfunction was more common in patients with larger aortic root diameters (≥4.0 cm: Odds ratio = 4.5, 95% confidence interval = 1.2 to 17.1) but was not associated with other cardiovascular manifestations of MFS or traditional atherosclerotic risk factors. In conclusion, apart from significant valvular pathology, LV systolic dysfunction was prevalent in MFS from a young age, suggestive of a primary cardiomyopathy. LV dysfunction was typically mild and subclinical and occurred more commonly in patients with more pronounced aortopathies.

The impact of sex and gender on aortic events in patients with Marfan syndrome.

OBJECTIVES: The aim of this study was to explore sex and gender differences regarding aortic events in Marfan patients. METHODS: We analysed all data from our connective tissue disorder database. Only patients with Marfan syndrome were included. For analysis, patients were divided by sex. Female patients were further divided into 2 subgroups: with versus without children. Aortic events were defined as Stanford type A aortic dissection (TAAD) or type B aortic dissection (TBAD) or any aortic intervention. RESULTS: A population of 183 Marfan patients was analysed for the purpose of this study. One hundred four (57%) were male and 79 (43%) were female patients. Thirty-seven (47%) of the 79 female patients had at least 1 child. Male patients had a significantly higher probability of experiencing an aortic event (P = 0.015) compared to female patients. However, there was no increased probability for recurrent events in male patients compared to female patients (P = 0.063). Follow-up revealed no sex and gender differences in the occurrence of Stanford TAAD or TBAD between male and female patients (P = 0.324/P = 0.534). While 11% of women with children suffered from peripartum aortic events, 24% experienced Stanford TAAD unrelated to pregnancy. CONCLUSIONS: Male patients have a higher risk of aortic events than female patients. The majority of women were not aware of their Marfan syndrome diagnosis before conceiving. One out of 10 women suffered from peripartum Stanford TAAD or TBAD. Twice as many female patients with children suffered from aortic dissection unrelated to childbirth. There were no sex and gender differences affecting mortality in Marfan patients.

Optimizing evaluation in pediatric and young adult patients with Marfan syndrome: Novel longitudinal metrics to track growth of aortic structures.

OBJECTIVE: Surveillance metrics in pediatric and young adult Marfan syndrome (pMFS) are challenging. We evaluated the utility of aortic root cross-sectional area/height index (CSA/Ht) on echocardiogram among pMFS patients as a risk stratification and surgical triage metric. METHODS: Genotype or phenotype positive pMFS patients aged 25 years or younger seen at our center from 2001 to 2020 were identified. Time-related transition to surgery was modeled using parametric methods. Predictive utility of CSA/Ht compared with aortic root diameter (ARd) and root Z score (ARz) were modeled using nonlinear multivariable parametric and nonparametric longitudinal regression models. RESULTS: Seventy-nine patients (43% female) presented at median age of 5.8 years (15th-85th percentile, 0.75-17 years) with median follow-up of 4.4 years (range, 0-18.5 years). Baseline echocardiography data were: CSA/Ht, 3.9 ± 1.4 cm2/m; ARd, 2.4 ± 0.89 cm; and ARz, 2.4 ± 1.7. CSA/Ht tracked ARd better compared with ARz (r = 0.91 vs 0.24). Eighteen patients underwent surgery. Surgical procedures included at least 2 components in 17 (aortic, mitral, tricuspid, aortic root, and arch procedures) and isolated mitral valve procedures in 1 patient. Time-related transition to surgery showed a prominent early phase to 1 year post presentation, followed by a slowly increasing late phase. CSA/Ht had a more linear correlation versus ARz during periods of rapid somatic growth in surgical patients. Surgical repair occurred at CSA/Ht between 5 and 7 cm2/m. CONCLUSIONS: CSA/Ht tracked ARd well over time. CSA/Ht between 5 and 7 cm2/m might be a promising metric for surgical triage in pMFS patients. CSA/Ht surgical threshold values in pMFS patients occurred at lower than current accepted "surgical" threshold values for CSA/Ht in adult Marfan syndrome patients.

Musculoskeletal diseases in Marfan syndrome: a nationwide registry study.

BACKGROUND: Marfan syndrome is associated with abnormalities in the musculoskeletal system including scoliosis, pectus deformities, protrusio acetabuli, and foot deformities. Over a life span, many patients with Marfan syndrome will need treatment; however, the musculoskeletal morbidity over a life span is not well described. The aim of the present study was to assess the overall burden of musculoskeletal disease in patients with Marfan syndrome. MATERIALS AND METHODS: A registry-based, nationwide epidemiological study of patients with a Ghent II verified Marfan syndrome diagnosis from 1977 to 2014. Each patient was matched on age, and sex with up to 100 controls from the background population. RESULTS: We identified 407 patients with Marfan syndrome and 40,700 controls and compared their musculoskeletal diagnoses and surgical treatments using Cox proportional hazards ratio (HR). The risk of a registration of a musculoskeletal diagnosis in patients with Marfan syndrome was significantly increased compared to controls (HR: 1.94 (1.69-2.24). One out of six with Marfan syndrome was registered with scoliosis (HR: 36.7 (27.5-48.9). Scoliosis was more common in women with Marfan syndrome compared to men (HR: 4.30 (1.73-1.08)). One out of 11 were registered with a pectus deformity HR: 40.8 (28.1-59.3), and one out of six with a deformity of the foot. Primarily pes planus (HR: 26.0 (15.2-44.3). The proportion of patients with Marfan syndrome (94/407) that underwent musculoskeletal surgery was also significantly higher (HR: 1.76 (1.43-2.16)). The major areas of surgery were the spine, pectups correction, and surgery of the foot/ankle. Ten patients with Marfan syndrome had elective orthopedic surgery without being recognized and diagnosed with Marfan syndrome until later in life. None of these had scoliosis, pectus deformity or a foot deformity. Among patients with an aortic dissection, the age at dissection was 34.3 years in those with at least one major musculoskeletal abnormality. In patients without a major abnormality the age at dissection was 45.1 years (p < 0.01). CONCLUSIONS: The extent of musculoskeletal disease is quite significant in Marfan syndrome, and many will need corrective surgery during their life span. Surgeons should be aware of undiagnosed patients with Marfan syndrome when treating patients with a Marfan syndrome like-phenotype.

Long-term durability of a reimplantation valve-sparing aortic root replacement can be expected in both Marfan syndrome and Loeys-Dietz syndrome.

OBJECTIVES: The goal of this study was to evaluate the surgical outcomes of a valve-sparing root replacement using the reimplantation technique for annuloaortic ectasia in patients with Marfan syndrome (MFS) and in those with Loeys-Dietz syndrome (LDS). METHODS: We reviewed 103 patients with MSF with mutations in the fibrillin-1 gene and 28 patients with LDS with mutations in the transforming growth factor-beta receptor and 2, SMAD3 and transforming growth factor beta-2 from 1988 to 2020. RESULTS: Forty-four (42.7%) patients with MFS [26 men, 31 (7.6) years] and 10 (35.7%) patients with Loeys-Dietz syndrome (LDS) [7 men, 22 (standard deviation: 8.6) years] who had no aortic dissection and underwent valve-sparing root replacement were included. The preoperative sinus diameter [46 (45-50.5) mm in those with MFS vs 48 (47-50) mm in those with LDS, p = 0.420] and the percentage of aortic insufficiency > grade 2+ [31.8% (10/44) in patients with MFS vs 10.0% (1/10) in those with LDS, p = 0.667] revealed no significant differences between the 2 groups. The cumulative incidences of aortic insufficiency greater than grade 1 (p = 0.588) and aortic valve reoperation (p = 0.310) were comparable between the 2 groups. Patients with LDS had a higher tendency towards aortic dissection after the initial operation (p = 0.061) and a significantly higher cumulative incidence of aortic reoperation (p = 0.003) versus those with MFS. CONCLUSIONS: Patients with MFS and those with LDS showed similar cumulative incidences of recurrent aortic valve insufficiency and aortic valve reoperation. Those with LDS revealed a higher cumulative incidence of aortic reoperation and a greater tendency towards aortic dissection after the initial operation compared with those with MFS.

Aortic events in pregnant patients with Marfan syndrome. Lessons from a multicenter study.

INTRODUCTION AND OBJECTIVES: Pregnancy in women with Marfan syndrome (MS) is associated with an increased risk of aortic events. The clinical evidence on pregnant patients with MS is limited and there is no specific consensus on their optimal management. We report our multicenter experience. METHODS: From January 2004 to January 2020, 632 patients with MS underwent periodic monitoring in Marfan units. During this period, we identified all pregnant women with MS and analyzed the incidence of aortic events during pregnancy and puerperium. RESULTS: There were 133 pregnancies in 89 women with MS (8 women with prior aortic surgery). There were no maternal deaths, but 5 women had aortic events during the third trimester and puerperium (type A dissections in 2, type B dissection in 1, and significant [≥ 3mm] aortic growth in 2). The aortic event rate was 3.7%. Pregestational aortic diameter≥ 40mm showed a nonsignificant association with aortic events (P=.058). Fetal mortality was 3% and 37.6% of births were cesarean deliveries. CONCLUSIONS: Women with MS have an increased risk of aortic events during pregnancy, especially in the third trimester and postpartum period. Patients with MS and aortic diameters ≥40mm should be assessed in experienced centers for prophylactic aortic surgery before pregnancy. It is important to provide early diagnosis, prepregnancy study of the aorta, beta-blocker administration, and close monitoring during pregnancy, especially during the last trimester and postpartum.

Intracranial Aneurysms in Patients with Marfan Syndrome: A Multicenter Propensity-Matched Analysis.

OBJECTIVE: We sought to identify risk factors for intracranial aneurysms (IAs) in Marfan syndrome (MFS) patients and to describe their characteristics. METHODS: Patients with confirmed MFS and vessel-dedicated brain imaging from January 1, 1980-December 1, 2020 were categorized according to the presence (IA) or absence (NIA) of IAs. Unmatched logistic regression analysis and propensity score matching were used for comparison. RESULTS: We included 159 patients, of whom 18 (11.3%) patients had radiographic diagnosis of IAs. Three patients (16.7%) had multiple lesions for a total of 24 IAs. One patient (5.5%) had de novo IA formation. Four patients (22.2%) underwent treatment: Two (11.1%) had open surgical clipping for ruptured aneurysms, and two (11.1%) patients had endovascular embolization for growth. In the unmatched analysis, current tobacco smoker status (odds ratio [OR]: 4.20; confidence interval [CI]: 1.11-15.6; P = 0.027) and history of coronary artery disease (CAD) (OR: 5.79; CI 1.76-20.2; P = 0.004) increased the odds for IA. Propensity score matching yielded 18 IA and 18 NIA patients matched for age, gender, race, prior stroke, and family history of aneurysms. History of CAD (IA = 11 [61.1%] vs. NIA = 4 (22.2%), P = 0.043) and current smoker status (IA = 6 [33.3%] vs. NIA = 0 (0%), P < 0.01) were significantly higher in the IA cohort. Body mass index (P = 0.622), diabetes (P = 0.180), hypertension (P = 0.732), prior stroke (P = 1.00), family history (P = 0.732), alcohol (P = 0.314), recreational drugs (P = 1.00), and other aneurysms (P = 0.585) were not statistically significant. CONCLUSIONS: Prevalence of IAs in our series of MFS patients was 11.3%, and de novo formation was 5.5%. MFS patients with a history of CAD and current smoker status had an increased risk of IA. Neurovascular radiographic screening should be considered in all patients with MFS, particularly in patients who smoke or have a history of heart disease.

Anesthesia in Parturients Presenting with Marfan Syndrome.

BACKGROUND: Pregnant women with Marfan syndrome (MS) have a high risk of aortic dissection around delivery and their optimal management requires a multi-disciplinary approach, including proper cardio-obstetric care and adequate pain management during labor, which may be difficult due to the high prevalence of dural ectasia (DE) in these patients. OBJECTIVES: To evaluate the multidisciplinary management of MS patients during labor. METHODS: Nineteen pregnant women (31 pregnancies) with MS were followed by a multi-disciplinary team (cardiologist, obstetrician, anesthesiologist) prior to delivery. RESULTS: Two patients had kyphoscoliosis; none had previous spine surgery nor complaints compatible with DE. In eight pregnancies (7 patients), aortic root diameter (ARd) before pregnancy was 40 to 46 mm. In this high-risk group, one patient underwent elective termination, two underwent an urgent cesarean section (CS) under general anesthesia, and five had elective CS; two under general anesthesia (GA), and three under spinal anesthesia. In 23 pregnancies (12 patients), ARd was < 40 mm. In this non-high-risk group three pregnancies (1 patient) were electively terminated. Of the remaining 20 deliveries (11 patients), 14 were vaginal deliveries, 9 with epidural analgesia and 5 without. Six patients had a CS; four under GA and two2 under spinal anesthesia. There were no epidural placement failures and no failed responses. There were 2 cases of aortic dissection, unrelated to the anesthetic management. CONCLUSIONS: The optimal anesthetic strategy during labor in MS patients should be decided by a multi-disciplinary team. Anesthetic complications due to DE were not encountered during neuraxial block.

Predictive Physical Manifestations for Progression of Scoliosis in Marfan Syndrome.

STUDY DESIGN: A retrospective study of the prospective cohort. OBJECTIVE: To demonstrate the accurate distribution of the severity of scoliosis in patients with Marfan syndrome, and to identify the predictive physical features for progression of scoliosis in Marfan syndrome. SUMMARY OF BACKGROUND DATA: To date, no study has unveiled the risk factors for the progression of scoliosis in Marfan syndrome. METHODS: We retrospectively obtained data from a prospective cohort of the Marfan syndrome clinic at our institute. We enrolled patients whose whole spine radiographs in the standing position were evaluated at the age of 15 or above, from January 2014 to March 2020. The collected variables were physical manifestations defined as in the systemic score of the revised Ghent nosology. We classified the degree of scoliosis into four categories: "not apparent," "mild" (10° ≤ Cobb < 25°), "moderate" (25° ≤ Cobb < 40°), and "severe" (40° ≤ Cobb or surgery conducted). To identify the risk factors for progression of scoliosis in Marfan syndrome, we conducted univariate and multivariate association analyses between severe scoliosis and each physical manifestation. RESULTS: We identified 131 eligible patients (61 men and 70 women) with a mean age of 31.2 years. Scoliosis with a Cobb angle of ≥10° was identified in 116 patients (88.5%). Moderate scoliosis was identified in 33 patients (25.2%) and severe scoliosis in 53 patients (40.5%). The prevalence of each physical manifestation was equivalent to that reported in previous studies. Multivariate logistic regression analysis revealed that female sex (odds ratio, 3.27) and positive wrist sign (4.45) were predictive factors for progression of scoliosis into severe state in patients with Marfan syndrome. CONCLUSIONS: The present study demonstrated the accurate distribution of the severity of scoliosis and identified the predictive factors for progression of scoliosis in patients with Marfan syndrome.Level of Evidence: 3.

Aortic Branch Aneurysms and Vascular Risk in Patients With Marfan Syndrome.

BACKGROUND: Aortic branch aneurysms are not included in the diagnostic criteria for Marfan syndrome (MFS); however, their prevalence and eventual prognostic significance are unknown. OBJECTIVES: The goal of this study was to assess the prevalence of aortic branch aneurysms in MFS and their relationship with aortic prognosis. METHODS: MFS patients with a pathogenic FBN1 genetic variant and at least one magnetic resonance or computed tomography angiography study assessing aortic branches were included. Aortic events and those related to aneurysm complications were recorded during follow-up. RESULTS: A total of 104 aneurysms were detected in 50 (26.7%) of the 187 patients with MFS (mean age 37.9 ± 14.4 years; 54% male) included in this study, with the iliac artery being the most common location (45 aneurysms). Thirty-one patients (62%) had >1 peripheral aneurysm, and surgery was performed in 5 (4.8%). Patients with aneurysms were older (41.9 ± 12.7 years vs. 36.7 ± 14.8 years; p = 0.040) and had more dilated aortic root (42.2 ± 6.4 mm vs. 38.8 ± 8.0 mm; p = 0.044) and dyslipidemia (31.0% vs. 9.7%; p = 0.001). In a subgroup of 95 patients with no previous aortic surgery or dissection followed up for 3.3 ± 2.6 years, the presence of arterial aneurysms was associated with a greater need for aortic surgery (hazard ratio: 3.4; 95% confidence interval: 1.1 to 10.3; p = 0.028) in a multivariable Cox analysis adjusted for age and aortic diameter. CONCLUSIONS: Aortic branch aneurysms are present in one-quarter of patients with MFS and are related to age and aortic dilation, and they independently predict the need for aortic surgery. The systematic use of whole-body vascular assessment is recommended to identify other sites of vascular involvement at risk for complications and to define the subgroup of patients with more aggressive aortic disease.

Non-aortic cardiovascular disease in Marfan syndrome: a nationwide epidemiological study.

OBJECTIVES: Studies indicate that other cardiovascular problems than aortic disease are a burden for patients with Marfan syndrome (MFS). The aim of the study was to assess the extent of this issue. METHODS: A registry-based population study of patients with a Ghent II verified MFS diagnosis. Each patient was matched with up to 100 controls on age and sex. From the Danish healthcare system, we identified 407 MFS patients (from 1977 to 2014) and their cardiovascular events and compared them with those in 40,700 controls. Total follow-up time was 16,439 person years. RESULTS: Mitral valve disease was significantly more common in MFS [HR: 58.9 (CI 38.1-91.1)] and happened earlier and more often in women than men with MFS [age at first registration: 22 vs. 38 years, HR: 2.1 (CI 1.0-4.4)]. Heart failure/cardiomyopathy was also more common in MFS [HR: 8.7 (CI 5.7-13.4)] and men were more affected than women, and at younger age [39 vs. 64 years, HR: 0.18 (CI 0.06-0.55)]. In all cases, atrioventricular block [HR: 4.9 (1.5-15.6)] was related to heart surgery. Supraventricular [HR: 9.7 (CI 7.5-12.7)] and ventricular tachycardia [HR: 7.7 (CI 4.2-14.3)] also occurred more often than in the control group. The risk of sudden cardiac death was increased [HR: 8.3 (CI 3.8-18.0)] but the etiology was unclear due to lack of autopsies. CONCLUSION: Non-aortic cardiovascular disease in patients with MFS is exceptionally prevalent and the range of diseases varies between women and men. Physicians caring for MFS patients must be aware of this large spectrum of cardiovascular diseases.
