Abstract
Children with Marfan (MFS) and Loeys-Dietz syndrome (LDS) report limitations in physical activities, sports, school, leisure, and work participation in daily life. This observational, cross-sectional, multicenter study explores associations between physical fitness and cardiovascular parameters, systemic manifestations, fatigue, and pain in children with MFS and LDS. Forty-two participants, aged 6-18 years (mean (SD) 11.5(3.7)), diagnosed with MFS (n = 36) or LDS (n = 6), were enrolled. Physical fitness was evaluated using the Fitkids Treadmill Test's time to exhaustion (TTE) outcome measure. Cardiovascular parameters (e.g., echocardiographic parameters, aortic surgery, cardiovascular medication) and systemic manifestations (systemic score of the revised Ghent criteria) were collected. Pain was obtained by visual analog scale. Fatigue was evaluated by PROMIS® Fatigue-10a-Pediatric-v2.0-short-form and PROMIS® Fatigue-10a-Parent-Proxy-v2.0-short-form. Multivariate linear regression analyses explored associations between physical fitness (dependent variable) and independent variables that emerged from the univariate linear regression analyses (criterion p < .05). The total group (MFS and LDS) and the MFS subgroup scored below norms on physical fitness TTE Z-score (mean (SD) -3.1 (2.9); -3.0 (3.0), respectively). Univariate analyses showed associations between TTE Z-score aortic surgery, fatigue, and pain (criterion p < .05). Multivariate analyses showed an association between physical fitness and pediatric self-reported fatigue that explained 48%; 49%, respectively, of TTE Z-score variance (F (1,18) = 18.6, p ≤ .001, r2 = .48; F (1,15) = 16,3, p = .01, r2 = .49, respectively). Conclusions: Physical fitness is low in children with MFS or LDS and associated with self-reported fatigue. Our findings emphasize the potential of standardized and tailored exercise programs to improve physical fitness and reduce fatigue, ultimately enhancing the physical activity and sports, school, leisure, and work participation of children with MFS and LDS. What is Known: • Marfan and Loeys-Dietz syndrome are heritable connective tissue disorders and share cardiovascular and systemic manifestations. • Children with Marfan and Loeys-Dietz syndrome report increased levels of disability, fatigue and pain, as well as reduced levels of physical activity, overall health and health-related quality of life. What is New: • Physical fitness is low in children with Marfan and Loeys-Dietz syndrome and associated with self-reported fatigue. • Our findings emphasize the potential of standardized and tailored exercise programs to improve physical fitness and reduce fatigue, ultimately enhancing the physical activity and sports, school, leisure, and work participation of children with Marfan and Loeys-Dietz syndrome.

Abstract
BACKGROUND This cross-sectional controlled study aims to assess health-related quality of life (HRQoL) of children and adolescents with a molecular diagnosis of Marfan syndrome (MFS) or related disorders and to evaluate the factors associated with HRQoL in this population. Sixty-three children with MFS and 124 age- and sex-matched healthy children were recruited. HRQoL was assessed using the Pediatric Quality of Life Inventory (PedsQL™) generic questionnaire. The correlation between HRQoL scores and the different continuous parameters (age, body mass index, disease severity, systemic score, aortic sinus diameter, and aerobic physical capacity) was evaluated using Pearson's or Spearman's coefficient. A multiple linear regression analysis was performed on the two health summary self-reported PedsQL™ scores (physical and psychosocial) to identify the factors associated with HRQoL in the MFS group. RESULTS Except for emotional functioning, all other domains of HRQoL (psychosocial and physical health, social and school functions) were significantly lower in children with MFS compared to matched healthy children. In the MFS group, the physical health summary score was significantly lower in female than in male patients (self-report: absolute difference [95%CI] = -8.7 [-17.0; -0.47], P = 0.04; proxy-report: absolute difference [95%CI] = -8.6 [-17.3; 0.02], P = 0.05) and also negatively correlated with the systemic score (self-report: R = -0.24, P = 0.06; proxy-report: R = -0.29, P = 0.03) and with the height Z-score (proxy-report: R = -0.29, P = 0.03). There was no significant difference in the physical health summary scores between the different genetic subgroups. In the subgroup of 27 patients who performed a cardiopulmonary exercise test, self- and proxy-reported physical health summary scores were highly correlated with their aerobic physical capacity assessed by peak oxygen consumption (VO2max) and ventilatory anaerobic threshold (VAT). In the multivariate analysis, the most important independent predictors of decreased physical health were increased height, decreased body mass index, decreased VAT and use of prophylactic therapy. CONCLUSIONS This study reports an impaired HRQoL in children and adolescents with MFS or related conditions, in comparison with matched healthy children. Educational and rehabilitation programs must be developed and evaluated to improve exercise capacity and HRQoL in these patients. TRIAL REGISTRATION ClinicalTrials.gov, NCT03236571 .

Abstract
BACKGROUND This study aims to analyze to what extent patients with Marfan syndrome (MFS) are affected by temporomandibular disorders (TMD) and its impact on oral health-related quality of life (OHRQoL). To collect data, an online questionnaire was created to recruit participants from Germany, Austria, and Switzerland through social media and support groups. The questionnaire consists of free-text questions, the German versions of the Oral Health Impact Profile (OHIP-G14), the Depression Anxiety Stress Scale (DASS), and the Graded Chronic Pain Status (GCPS). RESULTS A total of 76 participants with diagnosed MFS were included. Of these, 65.8% showed TMD symptoms, the most common being pain or stiffness of the masticatory muscles in the jaw angle (50.0%). Only 14.5% of the participants were already diagnosed with TMD. Of the participants with an increased likelihood of a depression disorder, 76.9% showed TMD symptoms. Of those with a critical score for an anxiety disorder, 90.9% showed TMD symptoms. 73.3% of participants with TMD symptoms reached the critical score for a stress disorder. TMD symptoms were associated with a higher risk for chronic pain. In the median, participants with TMD showed statistically notably higher OHIP-G14 scores than participants without TMD (11.5 [IQR 17] vs. 1 [IQR 3] points, p ≤ 0.001). CONCLUSION TMD symptoms had a noticeable impact on OHRQoL in patients with MFS, i.e., chronic pain and psychological impairment. TMD seems underdiagnosed, and more research is needed to prevent the associated chronification of pain and psychological burden to improve the OHRQoL.

Abstract
The mechanisms leading to cardiac remodeling in Marfan syndrome (MFS) are a matter of debate since it could be either due to structural dysfunction of the myocardial extracellular matrix or to increased afterload caused by the dilated aorta. We aim to characterize the presence of abnormal myocardial function in MFS and to investigate its potential association with increased afterload. Aorta, left ventricle (LV) and the postsystolic thickening (PST) were analyzed in echocardiography in Fbn1C1039G/+ mice and in patients with MFS in comparison with wild type (WT) mice and healthy humans. PST was more frequent in MFS than in WT mice (p < 0.05). MFS mice with PST showed larger aorta than those without PST. Patients with MFS showed larger aorta, poorer LV function and a higher prevalence of PST (56%) than did the healthy controls (23%); p = 0.003. Blood pressure was similar. The higher prevalence of PST in an experimental murine model and in MFS patients, regardless of systemic arterial pressure, suggests an increased afterload on the LV myocardium. This finding supports the use of PST as an indicator of myocardial damage and encourage searching for novel early preventive therapy.

Abstract
Mitral valve prolapse (MVP) is a commonly occurring heart condition defined by enlargement and superior displacement of the mitral valve leaflet(s) during systole. Although commonly seen as a standalone disorder, MVP has also been described in case reports and small studies of patients with various genetic syndromes. In this review, we analyzed the prevalence of MVP within syndromes where an association to MVP has previously been reported. We further discussed the shared biological pathways that cause MVP in these syndromes, as well as how MVP in turn causes a diverse array of cardiac and noncardiac complications. We found 105 studies that identified patients with mitral valve anomalies within 18 different genetic, developmental, and connective tissue diseases. We show that some disorders previously believed to have an increased prevalence of MVP, including osteogenesis imperfecta, fragile X syndrome, Down syndrome, and Pseudoxanthoma elasticum, have few to no studies that use up-to-date diagnostic criteria for the disease and therefore may be overestimating the prevalence of MVP within the syndrome. Additionally, we highlight that in contrast to early studies describing MVP as a benign entity, the clinical course experienced by patients can be heterogeneous and may cause significant cardiovascular morbidity and mortality. Currently only surgical correction of MVP is curative, but it is reserved for severe cases in which irreversible complications of MVP may already be established; therefore, a review of clinical guidelines to allow for earlier surgical intervention may be warranted to lower cardiovascular risk in patients with MVP.

Abstract
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.

Abstract
Marfan syndrome (MFS) is a genetic disorder that results in accelerated aortic root widening and aneurysm. However, management of MFS patients with blood pressure (BP)-lowering medications, such as angiotensin II (AngII) receptor blocker (ARB) losartan, continues to pose challenges due to their questionable efficacy at attenuating the rate of aortic root widening in patients. Herein we investigate the anti-aortic root widening effects of a sub-BP-lowering dose valsartan, an ARB previously linked to non-BP lowering anti-remodeling effects. Despite absence of BP-lowering effects, valsartan attenuated MFS aortic root widening by 75.9%, which was similar to a hypotensive dose of losartan (79.4%) when assessed by ultrasound echocardiography. Medial thickening, elastic fiber fragmentation, and phospho-ERK signaling were also inhibited to a similar degree with both treatments. Valsartan and losartan decreased vascular contractility ex vivo between 60% and 80%, in a nitric oxide (NO)-sensitive fashion. Valsartan increased acetylcholine (Ach)-induced vessel relaxation and phospho-eNOS levels in the aortic vessel supporting BP-independent activation of protective endothelial function, which is critical to ARB-mediated aortic root stability. This study supports the concept of achieving aortic root stability with valsartan in absence of BP-lowering effects, which may help address efficacy and compliance issues with losartan-based MFS patient management.

Abstract
We treated a man with co-incident Marfan-like connective tissue disease with morphologic left ventricular non-compaction (LVNC). He underwent valve-sparing aortic root replacement because of aortic root dilation at 43 years old. Pathological findings of the aorta revealed cystic medio-necrosis, consistent with Marfan syndrome. He developed congestive heart failure caused by LVNC at 47 years old. His daughter had scoliosis, and he had several physical characteristics suggestive of Marfan syndrome. We herein report a rare case of a patient who had Marfan-like connective disease with an LVNC appearance.

Abstract
Patients with Marfan syndrome (MFS), a connective tissue disorder caused by pathogenic variants in the gene encoding the extracellular matrix protein fibrillin-1, have an increased prevalence of primary cardiomyopathy, arrhythmias, and sudden cardiac death. We have performed an in-depth in vivo and ex vivo study of the cardiac phenotype of Fbn1mgR/mgR mice, an established mouse model of MFS with a severely reduced expression of fibrillin-1. Using ultrasound measurements, we confirmed the presence of aortic dilatation and observed cardiac diastolic dysfunction in male Fbn1mgR/mgR mice. Upon post-mortem examination, we discovered that the mutant mice consistently presented myocardial lesions at the level of the right ventricular free wall, which we characterized as spontaneous pseudoaneurysms. Histological investigation demonstrated a decrease in myocardial compaction in the MFS mouse model. Furthermore, continuous 24 h electrocardiographic analysis showed a decreased heart rate variability and an increased prevalence of extrasystolic arrhythmic events in Fbn1mgR/mgR mice compared to wild-type littermates. Taken together, in this paper we document a previously unreported cardiac phenotype in the Fbn1mgR/mgR MFS mouse model and provide a detailed characterization of the cardiac dysfunction and rhythm disorders which are caused by fibrillin-1 deficiency. These findings highlight the wide spectrum of cardiac manifestations of MFS, which might have implications for patient care.

Abstract
Background Several devices have been proposed to assess arterial stiffness in clinical daily use over the past few years, by estimating aortic pulse wave velocity (PWV) from a single measurement of brachial oscillometric blood pressure, using patented algorithms. It is uncertain if these systems are able to provide additional elements, beyond the contribution carried by age and blood pressure levels, in the definition of early vascular damage expressed by the stiffening of the arterial wall. Methods and Results The aim of our study was to compare the estimated algorithm-based PWV values, provided by the Mobil-O-Graph system, with the standard noninvasive assessment of aortic PWV in patients with Marfan syndrome (ie, in subjects characterized by premature aortic stiffening and low blood pressure values). Aortic stiffness was simultaneously evaluated by carotid-femoral PWV with a validated arterial tonometer and estimated with an arm cuff-based ambulatory blood pressure monitoring Mobil-O-Graph device on 103 patients with Marfan syndrome (50 men; mean± SD age, 38±15 years). Aortic PWV, estimated by the Mobil-O-Graph, was significantly ( P<0.0001) lower (mean± SD, 6.1±1.3 m/s) than carotid-femoral PWV provided by arterial tonometry (mean± SD , 8.8±3.1 m/s). The average of differences between PWV values provided by the 2 methods (±1.96×SD) was -2.7±5.7 m/s. Conclusions The Mobil-O-Graph provides PWV values related to an ideal subject for a given age and blood pressure, but it is not able to evaluate early vascular aging expressed by high PWV in the individual patient. This is well shown in patients with Marfan syndrome.

Abstract
Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder with considerable inter- and intra-familial clinical variability. The contribution of inherited modifiers to variability has not been quantified. We analyzed the distribution of 23 clinical features in 1306 well-phenotyped MFS patients carrying FBN1 mutations. We found strong correlations between features within the same system (i.e., ophthalmology vs. skeletal vs. cardiovascular) suggesting common underlying determinants, while features belonging to different systems were largely uncorrelated. We adapted a classical quantitative genetics model to estimate the heritability of each clinical feature from phenotypic correlations between relatives. Most clinical features showed strong familial aggregation and high heritability. We found a significant contribution by the major locus on the phenotypic variance only for ectopia lentis using a new strategy. Finally, we found evidence for the “Carter effect” in the MFS cardiovascular phenotype, which supports a polygenic model for MFS cardiovascular variability and indicates additional risk for children of MFS mothers with an aortic event. Our results demonstrate that an important part of the phenotypic variability in MFS is under the control of inherited modifiers, widely shared between features within the same system, but not among different systems. Further research must be performed to identify genetic modifiers of MFS severity.

Abstract
Genome-scale high-throughput sequencing enables the detection of unprecedented numbers of sequence variants. Variant filtering and interpretation are facilitated by mutation databases, in silico tools, and population-based reference datasets such as ExAC/gnomAD, while variants are classified using the ACMG/AMP guidelines. These methods, however, pose clinically relevant challenges. We queried the gnomAD dataset for (likely) pathogenic variants in genes causing autosomal-dominant disorders. Furthermore, focusing on the fibrillinopathies Marfan syndrome (MFS) and congenital contractural arachnodactyly (CCA), we screened 500 genomes of our patients for co-occurring variants in FBN1 and FBN2. In gnomAD, we detected 2653 (likely) pathogenic variants in 253 genes associated with autosomal-dominant disorders, enabling the estimation of variant-filtering thresholds and disease predisposition/prevalence rates. In our database, we discovered two families with hitherto unreported co-occurrence of FBN1/FBN2 variants causing phenotypes with mixed or modified MFS/CCA clinical features. We show that (likely) pathogenic gnomAD variants may be more frequent than expected and are challenging to classify according to the ACMG/AMP guidelines as well as that fibrillinopathies are likely underdiagnosed and may co-occur. Consequently, selection of appropriate frequency cutoffs, recognition of digenic variants, and variant classification represent considerable challenges in variant interpretation. Neglecting these challenges may lead to incomplete or missed diagnoses.

Abstract
BACKGROUND Marfan syndrome predisposes to aortic aneurysm, dissection, and rupture. We sought to investigate aortic 4-dimensional (4D) relative pressure maps derived from 4D flow cardiovascular magnetic resonance to identify disease characteristic alterations of the intraaortic pressure field in Marfan patients with aortic root dilation compared with age- and sex-matched healthy controls. METHODS This prospective case-control study included 11 Marfan patients with aortic root dilation (31 ± 5 years, 5 female) and 11 age- and sex-matched healthy controls (31 ± 8 years, 5 female) undergoing 4D flow cardiovascular magnetic resonance of the thoracic aorta. 4D relative pressure maps were computed and compared between groups for 8 aortic regions. RESULTS Aortic root diameters were significantly larger in patients compared with controls (43 vs 31 mm, P < .001), but not in the proximal descending aorta (23 vs 21 mm, P = .19). Regional pressure gradients over the cardiac cycle were significantly altered in Marfan patients with significantly higher minimum pressure gradients in the proximal ascending aorta (-44.3 vs -97.0 mm Hg/m, P < .001) and significantly lower maximum pressure gradients in the proximal descending aorta (55.1 vs 82.3 mm Hg/m, P < .01). The latter finding was associated with pathologic vortical flow patterns. Regional pressure gradient at mid systole significantly correlated with aortic diameter (proximal ascending aorta: r = 0.73, P < .001; proximal descending aorta: r = -0.59, P = .004). CONCLUSIONS Noninvasive 4D pressure mapping derived from 4D flow cardiovascular magnetic resonance revealed significant alterations of spatiotemporal pressure characteristics in the thoracic aorta of Marfan patients. These alterations were most pronounced in the proximal ascending aorta and the proximal descending aorta, corresponding to the regions where aortic dissections often originate in Marfan patients.

Abstract
Patients with the Marfan syndrome (MFS) are at risk for sudden death. The contribution of arrhythmias is unclear. This study examines the prevalence of arrhythmias in children with the MFS and their relation to clinical and/or echocardiographic factors. Data from the Pediatric Heart Network randomized trial of atenolol versus losartan in MFS were analyzed (6 months to 25 years old, aortic root diameter z-score > 3.0, no previous aortic surgery and/or dissection). Baseline 24-hour ambulatory electrocardiographic monitoring was performed. Significant ventricular ectopy (VE) and supraventricular ectopy (SVE) were defined as ≥10 VE or SVE/hour, or the presence of high-grade ectopy. Three-year composite clinical outcome of death, aortic dissection, or aortic root replacement was analyzed. There were 274 analyzable monitors on unique patients from 11 centers. Twenty subjects (7%) had significant VE, 13 (5%) significant SVE; of these, 2 (1%) had both. None had sustained ventricular or supraventricular tachycardia. VE was independently associated with increasing number of major Ghent criteria (odds ratio [OR] = 2.13/each additional criterion, p = 0.03) and greater left ventricular end-diastolic dimension z-score (OR = 1.47/each 1 unit increase in z-score, p = 0.01). SVE was independently associated with greater aortic sinotubular junction diameter z-score (OR = 1.56/each 1 unit increase in z-score, p = 0.03). The composite clinical outcome (14 events) was not related to VE or SVE (p ≥ 0.3), but was independently related to heart rate variability (higher triangular index). In conclusion, in this cohort, VE and SVE were rare. VE was related to larger BSA-adjusted left ventricular size. Routine ambulatory electrocardiographic monitoring may be useful for risk stratification in select MFS patients.

Abstract
PURPOSE Hereditary connective tissue disorders (HCTDs), such as classic Ehlers-Danlos syndrome (cEDS) and Marfan syndrome (MS) share overlapping features like hypermobility and tissue fragility. In clinical practice it remains a challenge to distinguish children and adolescents with HCTD from healthy children. The purpose of this study was to investigate the biomechanical properties of the patellar tendon and joint laxity (Beighton score) in children with HCTDs (n = 7) compared to healthy controls (n = 14). METHODS The mechanical properties of the patellar tendon were assessed using simultaneous force and ultrasonographic measurements during isometric ramp contractions. Ultrasonography was also used to measure tendon dimensions. The HCTD children were matched with 2 healthy controls with regard to age, body mass index (BMI), sex and physical activity level. RESULTS The HCTD children had a greater degree of joint laxity (P < 0.01). Although, the patellar tendon dimensions did not differ significantly between the two groups, the HCTD children showed a tendency toward a larger patellar tendon cross-sectional area (CSA) (35%, P = 0.19). Moreover, stiffness did not differ between the two groups, but secant modulus was 27% lower in children with a HCTD (P = 0.05) at common force and 34% lower at maximum force (P = 0.02). CONCLUSIONS The present study demonstrates for the first time that children with HCTDs have lower material properties (modulus) of their patellar tendon, which may be indicative of general impairment of connective tissue mechanics related to their increased joint laxity.

Abstract
Neonatal Marfan syndrome, in contrast to classical Marfan syndrome, is characterized by rapidly progressive multi-valvular cardiac disease and death from congestive heart failure, typically within the first year of life. Due to the rarity of this condition, treatment for neonatal Marfan syndrome has not been well studied. In this report, a combination of losartan and propranolol reduced the aortic root dilatation rate after three months of losartan therapy. Genetic analysis in this patient revealed a mutation in exon 25 of the FBN1 gene, which typically results in a shorter life expectancy. However, the patient's heart failure was controlled by losartan, propranolol and other anti-congestive medications, which may have prolonged his survival.

Abstract
OBJECTIVE To discover whether patients with aortic root dilation and leptosomic features but without a diagnosis of Marfan syndrome (MFS) fare similarly to patients with MFS. METHODS Of 124 patients with aortic root dilation identified from August 1, 1994, through October 31, 2012, 66 had MFS and 58 had leptosomic features but did not meet the Ghent criteria. Genetic testing was performed in 35% of patients (n=43). We compared z scores and aortic root diameters for patients who presented with aortic root dilation with and without an MFS diagnosis and with and without aortic root repair. RESULTS No difference existed in initial aortic root diameters between groups (P=.15); however, mean ± SD z scores for patients without MFS and with MFS were 3.1±2.3 vs 4.5±3.2 (P=.005). Fourteen of 58 patients (24%) without MFS and 35 (53%) with MFS underwent aortic root operations (P<.05). For both groups who did not have surgery, aortic root diameters and z scores remained similar at follow-up (P=.20), as did 10-year survival: MFS, 100%; no MFS, 94.1% (P=.98). No significant difference was found for mean ± SD root diameter (no MFS, 38.9±7.3 mm; MFS, 35±8.6 mm; P=.06) or z score (no MFS, 2.4±2.0; MFS, 2.1±2.0; P=.53) for patients who underwent surgery. Two patients in each group had aortic root dissections. CONCLUSION Similar rates of aortic dissection between the 2 groups warrant further study regarding patients with leptosomic features but no diagnosis of MFS. Aortic root dilation progressed similarly in patients who did not undergo surgery.

Abstract
BACKGROUND AND AIM OF THE STUDY The study aim was to compare long-term results of Marfan syndrome (MFS) patients affected by aortic root disease undergoing aortic root replacement with the Bentall or David operation. METHODS Since 1994, a total of 59 patients has been followed at the authors' Marfan Center, having undergone either a Bentall operation (Bentall group, n = 30) or a David operation (David group, n = 29). RESULTS No operative mortality was recorded. After 20 years (mean follow up 97 ± 82 months; range 1 to 369 months) no prosthesis-related major bleeding or thromboembolic events had been observed; the 20-year survival was 94 ± 6% in the Bentall group, and 100% in the David group (p = 0.32). Freedom from reintervention for aortic valve dysfunction was 100% in the Bentall group, and 75 ± 13% in the David group (p = 0.04). This inter-group difference became relevant after the first eight-year period of follow-up, and was mainly associated with a particular familiar genetic phenotype involving three out of four reoperated patients. Freedom from all-cause death, myocardial infarction, stroke, prosthetic valve-related complications, and reintervention on any aortic segment was 69 ± 12% in the Bentall group, and 67 ± 14% in the David group (p = 0.33). CONCLUSIONS The Bentall and David operations are both associated with satisfactory long-term results in MFS patients. The low rate of valve prosthesis-related complications suggested that the Bentall operation would continue to be a standard surgical treatment. The reimplantation technique, adopted for less-dilated aortas, provides satisfactory freedom from reoperation. Careful attention should be paid to the reimplantation technique in patients affected by a serious familiar genetic phenotype.

Abstract
RATIONALE Craniosynostosis is a disorder characterized by premature fusion of cranial sutures with subsequent development of abnormal craniofacial contour associated with variable skeletal and extra-skeletal abnormalities. In this family syndromic type of craniosynostosis was recognized and the etiology behind diverse forms of deformities have been diagnosed. PATIENT CONCERNS The negative impact of the disorder on the child and his family is enormous. Particularly when the diagnosis is late and little can be done. Though counselling the family through discussing the whole picture of the disorder might lessens their concern. DIAGNOSES Diagnosis is the corner stone of management. In this paper we aimed to sensitize pediatricians, physicians, and orthopedic surgeons concerning the necessity to recognize syndromic associations early on. INTERVENTIONS Patients with syndromic craniosynostosis are usually associated with a complexity of malformation complex. Craniofacial surgery can be of remarkable help if the diagnosis is made early. It requires a series of corrections to avoid intellectual disability and other neurological deficits.The timing of interventions is strongly correlated on the timing of diagnosis. OUTCOMES The earliest the diagnoses, the much better the outcomes are. And consequently avert the psychological and the financial cost on the patient and his family. LESSONS The golden principle of medicine should prevail in all medical disciplines, which states: The more you see, the more you know and conversely the more you know is the more you see.

Abstract
Marfan syndrome (MFS) is an autosomal-dominant disorder of connective tissue caused by mutations in the fibrillin-1 (FBN1) gene. Mortality is often due to aortic dissection and rupture. We investigated the structural and functional properties of the heart and aorta in a [Fbn1C1039G/+] MFS mouse using high-resolution ultrasound (echo) and optical coherence tomography (OCT). Echo was performed on 6- and 12-month old wild type (WT) and MFS mice (n = 8). In vivo pulse wave velocity (PWV), aortic root diameter, ejection fraction, stroke volume, left ventricular (LV) wall thickness, LV mass and mitral valve early and atrial velocities (E/A) ratio were measured by high resolution echocardiography. OCT was performed on 12-month old WT and MFS fixed mouse hearts to measure ventricular volume and mass. The PWV was significantly increased in 6-mo MFS vs. WT (366.6 ± 19.9 vs. 205.2 ± 18.1 cm/s; p = 0.003) and 12-mo MFS vs. WT (459.5 ± 42.3 vs. 205.3 ± 30.3 cm/s; p< 0.0001). PWV increased with age in MFS mice only. We also found a significantly enlarged aortic root and decreased E/A ratio in MFS mice compared with WT for both age groups. The [Fbn1C1039G/+] mouse model of MFS replicates many of the anomalies of Marfan patients including significant aortic dilation, central aortic stiffness, LV systolic and diastolic dysfunction. This is the first demonstration of the direct measurement in vivo of pulse wave velocity non-invasively in the aortic arch of MFS mice, a robust measure of aortic stiffness and a critical clinical parameter for the assessment of pathology in the Marfan syndrome.

Abstract
Fibrillin-1 is a large glycoprotein encoded by the FBN1 gene in humans. It provides strength and elasticity to connective tissues and is involved in regulating the bioavailability of the growth factor TGFβ. Mutations in FBN1 may be associated with depleted or abnormal adipose tissue, seen in some patients with Marfan syndrome and lipodystrophies. As this lack of adipose tissue does not result in high morbidity or mortality, it is generally under-appreciated, but is a cause of psychosocial problems particularly to young patients. We examined the role of fibrillin-1 in adipogenesis. In inbred mouse strains we found significant variation in the level of expression in the Fbn1 gene that correlated with variation in several measures of body fat, suggesting that mouse fibrillin-1 is associated with the level of fat tissue. Furthermore, we found that FBN1 mRNA was up-regulated in the adipose tissue of obese women compared to non-obese, and associated with an increase in adipocyte size. We used human mesenchymal stem cells differentiated in culture to adipocytes to show that fibrillin-1 declines after the initiation of differentiation. Gene expression results from a similar experiment (available through the FANTOM5 project) revealed that the decline in fibrillin-1 protein was paralleled by a decline in FBN1 mRNA. Examination of the FBN1 gene showed that the region commonly affected in FBN1-associated lipodystrophy is highly conserved both across the three human fibrillin genes and across genes encoding fibrillin-1 in vertebrates. These results suggest that fibrillin-1 is involved as the undifferentiated mesenchymal stem cells transition to adipogenesis but then declines as the developing adipocytes take on their final phenotype. Since the C-terminal peptide of fibrillin-1 is a glucogenic hormone, individuals with low fibrillin-1 (for example with FBN1 mutations associated with lipodystrophy) may fail to differentiate adipocytes and/or to accumulate adipocyte lipids, although this still needs to be shown experimentally.

Abstract
Objectives Marfan syndrome is an autosomal dominant inherited disorder of connective tissue. The vascular complications of Marfan syndrome have the biggest impact on life expectancy. The aorta of Marfan patients reveals degradation of elastin layers caused by increased proteolytic activity of matrix metalloproteinases (MMPs). In this study we performed adenoviral gene transfer of human tissue inhibitor of matrix metalloproteinases-1 (hTIMP-1) in aortic grafts of fibrillin-1 deficient Marfan mice (mgR/mgR) in order to reduce elastolysis. Methods We performed heterotopic infrarenal transplantation of the thoracic aorta in female mice (n = 7 per group). Before implantation, mgR/mgR and wild-type aortas (WT, C57BL/6) were transduced ex vivo with an adenoviral vector coding for human TIMP-1 (Ad.hTIMP-1) or β-galactosidase (Ad.β-Gal). As control mgR/mgR and wild-type aortas received no gene therapy. Thirty days after surgery, overexpression of the transgene was assessed by immunohistochemistry (IHC) and collagen in situ zymography. Histologic staining was performed to investigate inflammation, the neointimal index (NI), and elastin breaks. Endothelial barrier function of native not virus-exposed aortas was evaluated by perfusion of fluorescent albumin and examinations of virus-exposed tissue were performed by transmission electron microscopy (TEM). Results IHC and ISZ revealed sufficient expression of the transgene. Severe cellular inflammation and intima hyperplasia were seen only in adenovirus treated mgR/mgR aortas (Ad.β-Gal, Ad.hTIMP-1 NI: 0.23; 0.43), but not in native and Ad.hTIMP-1 treated WT (NI: 0.01; 0.00). Compared to native mgR/mgR and Ad.hTIMP-1 treated WT aorta, the NI is highly significant greater in Ad.hTIMP-1 transduced mgR/mgR aorta (p = 0.001; p = 0.001). As expected, untreated Marfan grafts showed significant more elastolysis compared to WT (p = 0.001). However, elastolysis in Marfan aortas was not reduced by adenoviral overexpression of hTIMP-1 (compared to untreated Marfan aorta: Ad.hTIMP-1 p = 0.902; control Ad.β-Gal. p = 0.165). The virus-untreated and not transplanted mgR/mgR aorta revealed a significant increase of albumin diffusion through the endothelial barrier (p = 0.037). TEM analysis of adenovirus-exposed mgR/mgR aortas displayed disruption of the basement membrane and basolateral space. Conclusions Murine Marfan aortic grafts developed severe inflammation after adenoviral contact. We demonstrated that fibrillin-1 deficiency is associated with relevant dysfunction of the endothelial barrier that enables adenovirus to induce vessel-harming inflammation. Endothelial dysfunction may play a pivotal role in the development of the vascular phenotype of Marfan syndrome.

Abstract
Two hundred thirty patients were prospectively enrolled in this study and completed various portions of the Short Form 36 and a study-specific questionnaire (visual analog scale 1 to 10, comprising three separate questionnaires) to evaluate quality of life and function in patients with Marfan syndrome. The greatest health concern was cardiac problems (high in 70% of patients), followed by spine issues and generalized fatigue (both high, in 53%). The most severe reported pain involved the back: 105 patients (46%) rated pain as 6 to 10 on the visual analog scale. Among the 72 patients who responded to work life questions, work hours were reduced because of treatment in 59 (82%) or directly because of Marfan syndrome in 29 (40%). Across all Short Form 36 domains, patients scored significantly lower than United States population norms (p<.05); physical health scores were considerably lower than mental health scores.

Abstract
PURPOSE To evaluate corneal air-puff deformation responses and ocular geometry as predictors of Marfan syndrome. DESIGN Prospective observational clinical study. METHODS Sixteen investigator-derived, 4 standard Ocular Response Analyzer (ORA), and geometric variables from corneal tomography and optical biometry using Oculus Pentacam and IOL Master were assessed for discriminative value in Marfan syndrome, measuring right eyes of 24 control and 13 Marfan syndrome subjects. Area under the receiver operating characteristic (AUROC) curve was assessed in univariate and multivariate analyses. RESULTS Six investigator-derived ORA variables successfully discriminated Marfan syndrome. The best lone disease predictor was Concavity Min (Marfan syndrome 47.5 ± 20, control 69 ± 14, P = .003; AUROC = 0.80). Corneal hysteresis (CH) and corneal resistance factor (CRF) were decreased (Marfan syndrome CH 9.45 ± 1.62, control CH 11.24 ± 1.21, P = .01; Marfan syndrome CRF 9.77 ± 1.65, control CRF 11.03 ± 1.72, P = .01) and corneas were flatter in Marfan syndrome (Marfan syndrome Kmean 41.25 ± 2.09 diopter, control Kmean 42.70 ± 1.81 diopter, P = .046). No significant differences were observed in central corneal thickness, axial eye length, or intraocular pressure. A multivariate regression model incorporating corneal curvature and hysteresis loop area (HLA) provided the best predictive value for Marfan syndrome (AUROC = 0.85). CONCLUSIONS This study describes novel biodynamic features of corneal deformation responses in Marfan syndrome, including increased deformation, decreased bending resistance, and decreased energy dissipation capacity. A predictive model incorporating HLA and corneal curvature shows greatest potential for noninvasive clinical diagnosis of Marfan syndrome.

Abstract
PURPOSE To report femtosecond laser-assisted cataract surgeries in patients with Marfan syndrome with mild, moderate, and severe lens subluxation. METHODS Case reports. RESULTS Two patients with Marfan syndrome underwent femtosecond laser-assisted cataract surgery (Alcon LenSx Lasers Inc., Aliso Viejo, CA). One patient had a mild lens subluxation in one eye and a moderate lens subluxation in the fellow eye. The other patient had a severe lens subluxation in one eye. In all eyes, the laser was able to perform a circular and free-floating anterior capsulotomy and lens fragmentation. In two of the eyes it was also helpful in decreasing corneal astigmatism by making corneal intrastromal relaxing incisions. There were no postoperative complications. CONCLUSIONS Femtosecond laser-assisted cataract surgery is an effective approach for cataract surgery in patients with Marfan syndrome with mild, moderate, and even severe lens subluxation, with the benefits of causing minimal further zonular damage and being able to treat corneal astigmatism with relaxing incisions.

Abstract
Patients with Marfan syndrome (MFS) presents with primary skeletal manifestations such as tall stature, chest wall abnormality, and scoliosis. These primary skeletal manifestations affect the growth pattern in MFS. Therefore, it is not appropriate to use normal growth charts to evaluate the growth status of MFS. We aimed to develop disease-specific growth charts for Korean MFS patients and to use these growth charts for understanding the growth patterns in MFS and managing of patients with MFS. Anthropometric data were available from 187 males and 152 females with MFS through a retrospective review of medical records. Disease-specific growth charts were generated and 3, 25, 50, 75, and 97 percentiles were calculated using the LMS (refers to λ, μ, and σ, respectively) smoothing procedure for height and weight. Comparisons between MFS patients and the general population were performed using a one-sample t-test. With regard to the height, the 50th percentile of MFS is above the normative 97th percentile in both genders. With regard to the weight, the 50 percentile of MFS is above the normative 75th percentile in male and between the normative 50th percentile and the 75th percentile in female. The disease-specific growth charts for Korean patients with MFS can be useful for monitoring growth patterns, planning the timing of growth-reductive therapy, predicting adult height and recording responses to growth-reductive therapy.

Abstract
Marfan syndrome (MFS), an autosomal dominant disorder of connective tissue, is due to defective fibrillin-1. Defects involve the cardiovascular system, the eye, the lungs, and the skeleton. The aim of the current study was to characterize the bone mineral status in children and adolescents with MFS. We performed an observational cross-sectional study and a longitudinal follow-up of two years. We enrolled 73 young patients with MFS (3-17years). A subset of 44 patients participated in the longitudinal study. Healthy children were studied as controls for biochemical analyses. Bone mineral density (BMD) was measured at lumbar spine, femoral neck and total femur by dual-energy X-ray absorptiometry. BMD values were expressed as Z-scores adjusted for height using height-for-age Z-scores. BMD measurements corrected for height were significantly lower than reference at all skeletal sites (P<0.0001). Patient on cardiac treatment with losartan had lower BMD measurements corrected for height compared to non-treated patients. Total femur BMD decreased significantly over time (P=0.027). BMD at the other two skeletal sites did not change significantly during follow-up, but remained significantly low compared to reference (P<0.0001). In conclusion, young patients with MFS have markedly low BMD at the lumbar spine and femur, and values show a tendency to decrease over time in the peripheral skeleton. Because increased life expectancy of MFS patients, the reduced BMD during childhood may lead to a low peak bone mass, increasing the fracture risk during adult life.

Abstract
BACKGROUND Marfan's Syndrome (MFS) is a disorder of connective tissue, mainly involving the cardiovascular, musculoskeletal, and ocular systems. The most severe problems include aortic root dilatation and dissection. Anesthetic management is vital for the improvement on perioperative morbidity. CASE REPORT 61-year-old male with MFS, presenting mainly with pectus carinatum, scoliosis, ectopia lens, previous spontaneous pneumothorax and aortal aneurysm and dissection submitted to thoracoabdominal aortic prosthesis placement. Underwent routine laparoscopic cholecystectomy due to lithiasis. Important findings on preoperative examination were thoracolumbar kyphoscoliosis, metallic murmur on cardiac exam. Chest radiograph revealed Cobb angle of 70°. Echocardiogram showed evidence of aortic mechanical prosthesis with no deficits. DISCUSSION Preoperative evaluation should focus on cardiopulmonary abnormalities. The anesthesiologist should be prepared for a potentially difficult intubation. Proper positioning and limb support prior to induction is crucial in order to avoid joint injuries. Consider antibiotic prophylaxis for subacute bacterial endocarditis. The patient should be carefully positioned to avoid joint injuries. Intraoperatively cardiovascular monitoring is mandatory: avoid maneuvers that can lead to tachycardia or hypertension, control airway pressure to prevent pneumothorax and maintain an adequate volemia to decrease chances of prolapse, especially if considering laparoscopic surgery. No single intraoperative anesthetic agent or technique has demonstrated superiority. Adequate postoperative pain management is vitally important to avoid the detrimental effects of hypertension and tachycardia.

Abstract
BACKGROUND Aortic-root dissection is the leading cause of death in Marfan's syndrome. Studies suggest that with regard to slowing aortic-root enlargement, losartan may be more effective than beta-blockers, the current standard therapy in most centers. METHODS We conducted a randomized trial comparing losartan with atenolol in children and young adults with Marfan's syndrome. The primary outcome was the rate of aortic-root enlargement, expressed as the change in the maximum aortic-root-diameter z score indexed to body-surface area (hereafter, aortic-root z score) over a 3-year period. Secondary outcomes included the rate of change in the absolute diameter of the aortic root; the rate of change in aortic regurgitation; the time to aortic dissection, aortic-root surgery, or death; somatic growth; and the incidence of adverse events. RESULTS From January 2007 through February 2011, a total of 21 clinical centers enrolled 608 participants, 6 months to 25 years of age (mean [±SD] age, 11.5±6.5 years in the atenolol group and 11.0±6.2 years in the losartan group), who had an aortic-root z score greater than 3.0. The baseline-adjusted rate of change in the mean (±SE) aortic-root z score did not differ significantly between the atenolol group and the losartan group (-0.139±0.013 and -0.107±0.013 standard-deviation units per year, respectively; P=0.08). Both slopes were significantly less than zero, indicating a decrease in the aortic-root diameter relative to body-surface area with either treatment. The 3-year rates of aortic-root surgery, aortic dissection, death, and a composite of these events did not differ significantly between the two treatment groups. CONCLUSIONS Among children and young adults with Marfan's syndrome who were randomly assigned to losartan or atenolol, we found no significant difference in the rate of aortic-root dilatation between the two treatment groups over a 3-year period.

Abstract
Marfan syndrome (MS) is a congenital disorder of the connective tissue characterized by aortic dilation with frequent progression to aortic aneurysms requiring surgical intervention. Although mutations in the fibrillin-1 (FBN1) gene have been recognized as the genetic cause of MS a long time ago, only recently deeper knowledge of the molecular mechanisms underlying fibrillin-1 biology and the crucial role of transforming growth factor-β and angiotensin II receptor type 1 antagonists have been elucidated. This review focuses on the most commonly used animal models to investigate the molecular mechanisms underlying MS, and on novel pharmacological strategies to reduce aortic dilation in MS.

Abstract
AIM Pulmonary involvement is not generally considered a main feature of Marfan syndrome, an autosomal connective tissue disorder caused by mutations in fibrillin 1. Thanks to the substantial progress in treatments, life expectation of these patients has been dramatically improved determining changes in different organ systems. The number of patients with pulmonary pathology may be higher than expected. Objective of the study was to evaluate the pulmonary involvement in all the patients referring to the largest Italian center for Marfan syndrome, assessing clinical examination and lung function tests. METHODS Clinical history, spirometry, lung volumes and diffusing capacity have been assessed in 64 patients of our national referral center. RESULTS None of the patients reported chronic respiratory symptoms. Fourteen percent reported a previous pneumothorax and 3 blebs and 45% had moderate to severe rib cage abnormalities. Twenty-three percent had cardiothoracic surgery. Two of the 19 patients with chest TC performed at our hospital were diagnosed with emphysema and were both non smoker; 7 had subpleural apical blebs. Only 37% of patients had normal lung function; 19% showed a restrictive pattern and 44% an obstructive pattern or an isolated diffusion impairment or an isolated hyperinflation. All patients with pneumothorax showed an obstructive pattern and diffusion impairment. CONCLUSION In the absence of early respiratory symptoms, pulmonary abnormalities should be detected and monitored before they aggravate. Particular attention should be paid to prevent pneumothorax. Our results support the importance of lung volume determination to identify patients in which pulmonary parenchyma require a careful chest CT evaluation.

Abstract
Patients with Marfan syndrome (MFS), a multisystem disorder caused by mutations in the gene encoding the extracellular matrix (ECM) protein fibrillin 1, are unusually vulnerable to stress-induced cardiac dysfunction. The prevailing view is that MFS-associated cardiac dysfunction is the result of aortic and/or valvular disease. Here, we determined that dilated cardiomyopathy (DCM) in fibrillin 1-deficient mice is a primary manifestation resulting from ECM-induced abnormal mechanosignaling by cardiomyocytes. MFS mice displayed spontaneous emergence of an enlarged and dysfunctional heart, altered physical properties of myocardial tissue, and biochemical evidence of chronic mechanical stress, including increased angiotensin II type I receptor (AT1R) signaling and abated focal adhesion kinase (FAK) activity. Partial fibrillin 1 gene inactivation in cardiomyocytes was sufficient to precipitate DCM in otherwise phenotypically normal mice. Consistent with abnormal mechanosignaling, normal cardiac size and function were restored in MFS mice treated with an AT1R antagonist and in MFS mice lacking AT1R or β-arrestin 2, but not in MFS mice treated with an angiotensin-converting enzyme inhibitor or lacking angiotensinogen. Conversely, DCM associated with abnormal AT1R and FAK signaling was the sole abnormality in mice that were haploinsufficient for both fibrillin 1 and β1 integrin. Collectively, these findings implicate fibrillin 1 in the physiological adaptation of cardiac muscle to elevated workload.

Abstract
We report a case of successful fiberoptic tracheal intubation through the supraglottic airway device air-Q in a 14-year-old boy in whom intubation was difficult because of Shprintzen-Goldberg syndrome. Shprintzen-Goldberg syndrome is a rare congenital disorder of connective tissue. The patient showed dysmorphic facies and weakness of connective tissue, and was scheduled to undergo abdominal surgery. After induction of general anesthesia, both attempts of laryngoscope-guided and AirwayScope -guided tracheal intubation failed, but a size-2 air-Q could be easily inserted. Fiberoptic tracheal intubation through the air-Q was successfully performed without any difficulty and was safe for his weak airway connective tissue. Supraglottic airway air-Q is a useful conduit for fiberoptic tracheal intubation under general anesthesia, especially in the case of a patient with weak connective tissue in whom intubation is difficult.

Abstract
The extracellular matrix (ECM) is a complex entity with structural proteins (such as fibrillins, collagen, elastin), ground substance (proteoglycans), modifying enzymes (ADAMTS, PLOD, lysyloxidases (LOX)) and cytokines that regulate morphogenesis, growth, homeostasis and repair (transforming growth factor-beta [TGF-beta], bone morphogenic protein [BMP]). Over the last decade, the intimate relationship between structural proteins and these growth factors has emerged. The study of the extracellular matrix in human conditions and relevant mouse models is gradually unmasking the key role of these structural molecules in the regulation of the bio-availability of these growth factors. Major progress has been made in the study of the cardiovascular system (1) and the first clues in the skeletal system have emerged. (2) In this review, we will discuss the clinical, molecular, and pathogenic aspects of Marfan syndrome, Loeys-Dietz syndrome and related disorders with emphasis on the role of fibrillins and TGF-beta.

Abstract
OBJECTIVES Strain and strain rate imaging have been reported to detect cardiac dysfunction more accurately than conventional methods in adults with Marfan syndrome, but their utility has not been proven in younger patients. We sought to determine whether strain and strain rate imaging would allow early detection of cardiac dysfunction in children and young adults with Marfan syndrome. METHODS Unoperated patients (<30 years) with Marfan syndrome and healthy control participants were prospectively enrolled. Patients with greater than mild mitral or aortic insufficiency were excluded. Left ventricular systolic function was assessed by standard M-mode imaging. The strain and strain rate values were obtained from apical 4-chamber (longitudinal) and parasternal short-axis views at basal and midventricular levels (radial and circumferential). Data from the two groups were compared by a t test. RESULTS Sixteen patients with Marfan syndrome (mean age ± SD, 14.4 ± 6.4 years; range, 5.8-28.9 years) and 26 controls (mean age, 12.4 + 4.4 year; range, 4.1-18.1 years) were enrolled. Demographics and left ventricular end-diastolic dimensions were similar between the patients with Marfan syndrome and the controls. The M-mode-derived shortening fraction was significantly lower in the patients with Marfan syndrome compared to the controls, even though the values were within normal limits. The patients with Marfan syndrome had lower regional radial and circumferential strain rates, but there were no significant difference in strain between the groups. CONCLUSIONS Strain rate imaging may be useful in detection of subclinical changes in cardiac function in patients with Marfan syndrome when conventional echocardiographic parameters are within normal limits. These findings may be clinically important and warrant closer follow-up of these patients to monitor for cardiac dysfunction.

Abstract
Mitral valve degeneration is a key component of the pathophysiology of Marfan syndrome. The biomechanical consequences of aging and genetic mutation in mitral valves are poorly understood because of limited tools to study this in mouse models. Our aim was to determine the global biomechanical and local cell-matrix deformation relationships in the aging and Marfan related Fbn1 mutated murine mitral valve. To conduct this investigation, a novel stretching apparatus and gripping method was implemented to directly quantify both global tissue biomechanics and local cellular deformation and matrix fiber realignment in murine mitral valves. Excised mitral valve leaflets from wild-type and Fbn1 mutant mice from 2 weeks to 10 months in age were tested in circumferential orientation under continuous laser optical imaging. Mouse mitral valves stiffen with age, correlating with increases in collagen fraction and matrix fiber alignment. Fbn1 mutation resulted in significantly more compliant valves (modulus 1.34 ± 0.12 vs. 2.51 ± 0.31 MPa, respectively, P<.01) at 4 months, corresponding with an increase in proportion of GAGs and decrease in elastin fraction. Local cellular deformation and fiber alignment change linearly with global tissue stretch, and these slopes become more extreme with aging. In comparison, Fbn1 mutated valves have decoupled cellular deformation and fiber alignment with tissue stretch. Taken together, quantitative understanding of multi-scale murine planar tissue biomechanics is essential for establishing consequences of aging and genetic mutations. Decoupling of local cell-matrix deformation kinematics with global tissue stretch may be an important mechanism of normal and pathological biomechanical remodeling in valves.

Abstract
Marfan's syndrome (MFS) is a systemic disorder of the connective tissues caused by insufficient fibrillin-1 microfibril formation and can cause cardiac complications, emphysema, ocular lens dislocation and severe periodontal disease. ADAMTSL6β, a microfibril-associated extracellular matrix protein that has been implicated in fibrillin-1 microfibril assembly is able to improve microfibril insufficiency in MFS mice model. These findings suggest a new therapeutic strategy for the treatment of MFS through ADAMTSL6β-mediated fibrillin-1 microfibril assembly. We here review effect on ADAMTSL6β to the improvement of microfibril insufficiency in periodontal tissue as a model.

Abstract
Optimal perfusion strategies for extensive aortic resection in patients with mega-aortic syndromes include: tailored myocardial preservation, antegrade cerebral perfusion, controlled hypothermia and selective organ perfusion. Typically, the aortic arch resection and elephant trunk procedure are performed under hypothermic circulatory arrest with myocardial and cerebral protection. However, mesenteric and systemic ischemia occur during circulatory arrest and commonly rely upon deep hypothermia alone for metabolic protection. We hypothesized that simultaneously controlled mesenteric and systemic perfusion can attenuate some of the metabolic debt accrued during circulatory arrest, which may help improve perioperative outcomes. The perfusion strategy consisted of delivering a 1 to 3 liter per minute flow at 25 degrees C to the head/upper body via right axillary graft and simultaneous perfusion to the lower body/ mesenteric organs of 1 to 3 liters per minute at 30 degrees C via a right femoral arterial graft. We describe our technique of simultaneous mesenteric, systemic, cerebral and myocardial perfusion, and protection utilized for a young male patient with Marfan's syndrome, while undergoing a valve sparing root replacement, total arch replacement and elephant trunk reconstruction. This perfusion technique allowed us to deliver differential flow rates and temperatures to the upper and lower body (cold head/warm lower body perfusion) to minimize ischemic debt and quickly reverse metabolic derangements.

Abstract
Marfan syndrome (MFS) is a hereditary connective tissue disorder. Studies of MFS have established the critical contribution of fibrillin-1 deficiency to disease progression through altered cell-matrix interactions and dysregulated TGF-β signalling. It is now known that the disease is caused by altered regulation of TGF-β. As a result, the definition of MFS- and MFS-related diseases as the prototypical structural disorder of the connective tissue has changed to that of a developmental abnormality with broad and complex effects on the morphogenesis and tissue remodelling.

Abstract
Marfan syndrome is a disorder of the connective tissue that is inherited in an autosomal-dominant fashion and that is caused by mutations in the gene coding for fibrillin-1, FBN1. Although complications of the syndrome may involve the eye, the lung and the skeleton, the high mortality of untreated cases results almost exclusively from cardiovascular complications, including aortic dissection, rupture and mitral valve regurgitation. The multiorgan involvement of many of these syndromes requires multidisciplinary expert centers that can increase the average life expectancy of affected patients from only 32 years to over 60 years. The present article both reviews classical standards of managing cardiovascular manifestations and highlights the surgical approach for aortic and mitral valve surgery in Marfan patients.
