Differences in Cardiovascular Manifestation of Marfan Syndrome Between Children and Adults. Pediatr Cardiol 2019; 40:393-403.

Abstract
Marfan syndrome (MFS) is a connective tissue disorder characterized by a broad range of clinical manifestations. Cardiovascular involvement is the most life-threatening aspect of the syndrome. Although abnormalities within the cardiovascular system in adults are well documented, there is still a paucity of data regarding manifestation of MFS in childhood. The aim of the study was to compare cardiovascular manifestation of MFS between children and adults. The study population consisted of 236 patients (144 children and 92 adults), who were referred to our department with suspicion of MFS. All patients underwent complete clinical evaluation in order to confirm the diagnosis of MFS according to the modified Ghent criteria. MFS was diagnosed in 101 (44 children and 57 adults) out of the 236 patients. The other patients were diagnosed with Ehlers-Danlos syndrome, Loeys-Dietz syndrome, MASS phenotype, ectopia lentis syndrome, marfanoid habitus and other rare syndromes. The most common cardiovascular abnormality was aortic root dilatation (81.19% of patients). It was found that both adults and children had similar high rates of aortic root dilatation. Similarly, there was no significant difference with regard to the prevalence of aortic valve regurgitation and mitral valve prolapse among children and adults. These findings equivocally indicate that the aforementioned abnormalities develop in early childhood, therefore, they may be used in the early identification of patients with MFS. Other assessed abnormalities, which included mitral valve regurgitation, pulmonary artery dilation, aneurysms of aortic arch, descending thoracic aorta and abdominal aorta were found mostly in adults, and thus, are of less use in the early detection of MFS.

Abstract
PURPOSE OF REVIEW Numerous studies have begun to unravel the genetic basis of not only aortic disease but also other forms of commonly encountered vascular diseases. The goal of this review is to provide clinicians a reference to help identify and diagnose different types of vascular disease with a genetic underpinning. RECENT FINDINGS Ongoing studies have identified numerous genes involved in the TGF-β signaling pathway that are also associated with thoracic aortic aneurysm and dissection, and it is possible to test for pathogenic variants in these genes in the clinical setting using commercially available genetic testing panels. Additional studies have begun to identify genetic variants associated with an increased risk of bicuspid aortic valve, abdominal aortic aneurysm, and fibromuscular dysplasia. With increased availability of low-cost genetic testing, clinicians are now able to not only definitively diagnose some vascular syndromes but also provide information on the risk of disease in other family members, as well as provide guidance in terms of family planning. As the cost of genetic testing continues to drop with the benefit of increasing insurance coverage, genetic data will increasingly become part of clinical care for many patients with vascular disease.

Abstract
Aortic root dilatation and its complications are known to be the most important and life limiting features in patients with Marfan syndrome (MFS). Since monitoring of patients, preventive medical and surgical treatments are available nowadays, other MFS pathologies are becoming more relevant for the outcome of the disease. Main pulmonary artery (MPA) dilatation is a cardiac finding, which has not been fully investigated in children. Due to the similarities in tissue composition of the aortic and pulmonary root, MPA dilatation may cause complications and require treatment. In addition, it may be a predictor for severe connective tissue involvement. We retrospectively examined 135 pediatric patients with MFS. 8.1% showed MPA dilatation. MPA dilatation was associated with earlier occurrence of aortic dilatation, mitral valve prolapse, and systemic manifestations of MFS compared with patients without MPA dilatation (p < 0.05). The presence of MPA dilatation was also associated with a higher incidence of ectopia lentis (p < 0.05). Medical treatment was started earlier in MPA dilatation patients than in those without (p < 0.05). We conclude that MPA dilatation is a sign of more severe vascular and connective tissue involvement. Regular examination of the pulmonary artery is essential in MFS to avoid complications. As medical treatment of life threatening MFS events has improved, other features of MFS need to be investigated to improve quality of life.

Abstract
Background Recent studies have shown Growth differentiation factor–15 (GDF-15) that is a member of the transforming growth factor β (TGF-β) superfamily might be a potential predictive cytokine for the prognosis of Acute coronary syndrome (ACS). However, there are discrepancies in these studies. Methods Publication searches of the PubMed/Medline and EMBASE databases were performed without any time or ethnicity restrictions. The inclusion and exclusion criteria, when clear, were addressed. Random effects models were used for all analyses. Publication bias was tested using funnel plots and the Egger test. Results We identified eight eligible studies that provided mortality data. Five of these studies provided recurrent myocardial infarction (MI) data. The maximal duration of follow-up ranged from 6 months to 6 years. A significant association was found between the patients with the highest and lowest GDF-15 levels (overall analyses) in terms of mortality (p < 0.00001; RR = 6.08; 95 % CI = 4.79–7.71) and recurrent MI (p < 0.00001; RR = 1.76; 95 % CI = 1.49–2.07). We also found significant associations between the subgroup analyses stratified by ACS types, cutoff points and follow-up durations (p < 0.001). The combined hazard ratio was high for GDF-15 to ACS (HR = 1.656, 95 % CI = 1.467–1.871). Conclusion High plasma GDF-15 levels are associated with an increased risk of mortality and recurrent MI in patients with ACS.

Abstract
Marfan syndrome (MFS) is a disease in which connective tissue becomes weak secondary to fibrillin-1 mutations, resulting in aortic dilatation, aneurysm formation, aortic dissection, aortic regurgitation and mitral valve prolapse. This autosomal dominantly inherited condition, which was first reported in 1895 and was more fully described in 1931, is characterised by abnormal Fibrillin-1 protein (FBN1) (discovered in 1990), which is encoded by the FBN1 gene (reported in 1991). In the 1970s, the life expectancy of people with MFS was 40-50 years, mainly due to increased risk of aortic dissection or heart failure from aortic or mitral regurgitation. However, due to advances in medical and surgical therapy, life expectancy has improved dramatically and is now comparable to that of the general population. We discuss the cardiac manifestations of MFS, the incidence of arrhythmia in this population, the standard of medical care for arrhythmia and valve insufficiency, and a new use of preventive medication to preserve the integrity of the aortic wall in patients with MFS.

Abstract
More than 30 heritable conditions are associated with thoracic aortic aneurysm and dissection (TAAD). Heritable syndromic conditions, such as Marfan syndrome, Loeys-Dietz syndrome, and vascular Ehlers-Danlos syndrome, have somewhat overlapping systemic features, but careful clinical assessment usually enables a diagnosis that can be validated with genetic testing. Nonsyndromic FTAAD can also occur and in 20%-25% of these probands mutations exist in genes that encode elements of the extracellular matrix, signalling pathways (especially involving transforming growth factor-β), and vascular smooth muscle cytoskeletal and contractile processes. Affected individuals with either a syndromic presentation or isolated TAAD can have mutations in the same gene. In this review we focus on the genes currently known to have causal mutations for syndromic and isolated FTAAD and outline the range of associated extracardiovascular and cardiovascular manifestations with each.

Abstract
Three international nosologies have been proposed for the diagnosis of Marfan syndrome (MFS): the Berlin nosology in 1988; the Ghent nosology in 1996 (Ghent-1); and the revised Ghent nosology in 2010 (Ghent-2). We reviewed the literature and discussed the challenges and concepts of diagnosing MFS in adults. Ghent-1 proposed more stringent clinical criteria, which led to the confirmation of MFS in only 32%–53% of patients formerly diagnosed with MFS according to the Berlin nosology. Conversely, both the Ghent-1 and Ghent-2 nosologies diagnosed MFS, and both yielded similar frequencies of MFS in persons with a causative FBN1 mutation (90% for Ghent-1 versus 92% for Ghent-2) and in persons not having a causative FBN1 mutation (15% versus 13%). Quality criteria for diagnostic methods include objectivity, reliability, and validity. However, the nosology-based diagnosis of MFS lacks a diagnostic reference standard and, hence, quality criteria such as sensitivity, specificity, or accuracy cannot be assessed. Medical utility of diagnosis implies congruency with the historical criteria of MFS, as well as with information about the etiology, pathogenesis, diagnostic triggers, prognostic triggers, and potential complications of MFS. In addition, social and psychological utilities of diagnostic criteria include acceptance by patients, patient organizations, clinicians and scientists, practicability, costs, and the reduction of anxiety. Since the utility of a diagnosis or exclusion of MFS is context-dependent, prioritization of utilities is a strategic decision in the process of nosology development. Screening tests for MFS should be used to identify persons with MFS. To confirm the diagnosis of MFS, Ghent-1 and Ghent-2 perform similarly, but Ghent-2 is easier to use. To maximize the utility of the diagnostic criteria of MFS, a fair and transparent process of nosology development is essential.

Abstract
BACKGROUND Echocardiographic upper normal limits of both main pulmonary artery (MPA) diameters (MPA-d) and ratio of MPA to aortic root diameter (MPA-r) are not defined in healthy adults. Accordingly, frequency of MPA dilatation based on echocardiography remains to be assessed in adults with Marfan syndrome (MFS). METHODS We enrolled 123 normal adults (72 men, 52 women aged 42 ± 14 years) and 98 patients with MFS (42 men, 56 women aged 39 ± 14 years) in a retrospective cross-sectional observational controlled study in four tertiary care centers. We defined outcome measures including upper normal limits of MPA-d and MPA-r as 95 quantile of normal persons, MPA dilatation as diameters > upper normal limits, MPA aneurysm as diameters >4 cm, and indication for surgery as MPA diameters >6 cm. RESULTS MPA diameters revealed normal distribution without correlation to age, sex, body weight, body height, body mass index and body surface area. The upper normal limit was 2.6 cm (95% confidence interval (CI) =2.44-2.76 cm) for MPA-d, and 1.05 (95% CI = .86-1.24) for MPA-r. MPA dilatation presented in 6 normal persons (4.9%) and in 68 MFS patients (69.4%; P < .001), MPA aneurysm presented only in MFS (15 patients; 15.3%; P < .001), and no patient required surgery. Mean MPA-r were increased in MFS (P < .001), but ratios >1.05 were equally frequent in 7 normal persons (5%) and in 8 MFS patients (10.5%; P = .161). MPA-r related to aortic root diameters (P = .042), reduced left ventricular ejection fraction (P = .006), and increased pulmonary artery systolic pressures (P = .040). No clinical manifestations of MFS and no FBN1 mutation characteristics related to MPA diameters. CONCLUSIONS We established 2.6 cm for MPA-d and 1.05 for MPA-r as upper normal limits. MFS exhibits a high prevalence of MPA dilatation and aneurysm. However, patients may require MPA surgery only in scarce circumstances, most likely because formation of marked MPA aneurysm may require LV dysfunction and increased PASP.

Abstract
Marfan's syndrome is a rare genetic disorder caused by a mutation of the gene FBN1, coding for the protein fibrillin-1. Cardiovascular, musculoskeletal and ophthalmic manifestations are the most commonly observed, but minor diagnostic criteria also include pulmonary manifestations. Pneumothorax, frequently relapsing, affects 5 to 11% of patients. Rib cage abnormalities (pectus excavatum or pectus carinatum) and apical blebs may contribute to their occurrence. Treatment does not require any specific procedure but there is an increased risk of recurrence. Pectus excavatum affects up to 60% of the patients, without any functional impairment in most cases. Surgery may be required (using the Nuss procedure) in case of cardiovascular or psychological symptoms. Marfan's syndrome is frequently associated with obstructive sleep apnoea, which may itself contribute to aortic dilatation. Some studies suggest a potential role of craniofacial abnormalities in the pathogenesis of sleep apnea in these patients. Pulmonologists should consider Marfan's syndrome when treating patients for recurrent spontaneous pneumothorax or rib cage abnormalities, since early detection of cardiac abnormalities improves the prognosis significantly.

Abstract
Background Marfan syndrome (MFS) is a rare autosomal dominantly inherited connective tissue disorder with an estimated prevalence of 1:5,000. More than 1000 variants have been previously reported to be associated with MFS. However, the disease-causing effect of these variants may be questionable as many of the original studies used low number of controls. To study whether there are possible false-positive variants associated with MFS, four in silico prediction tools (SIFT, Polyphen-2, Grantham score, and conservation across species) were used to predict the pathogenicity of these variant. Results Twenty-three out of 891 previously MFS-associated variants were identified in the ESP. These variants were distributed on 100 heterozygote carriers in 6494 screened individuals. This corresponds to a genotype prevalence of 1:65 for MFS. Using a more conservative approach (cutoff value of >2 carriers in the EPS), 10 variants affected a total of 82 individuals. This gives a genotype prevalence of 1:79 (82:6494) in the ESP. A significantly higher frequency of MFS-associated variants not present in the ESP were predicted to be pathogenic with the agreement of ≥3 prediction tools, compared to the variants present in the ESP (p = 3.5 × 10−15). Conclusions This study showed a higher genotype prevalence of MFS than expected from the phenotype prevalence in the general population. The high genotype prevalence suggests that these variants are not the monogenic cause of MFS. Therefore, caution should be taken with regard to disease stratification based on these previously reported MFS-associated variants.
