Correlation of structural defects in the ascending aortic wall to ultrasound parameters: benefits for decision-making process in aortic valve surgery. J Cardiothorac Surg 2018; 13:12. [PMID: 29347958 PMCID: PMC5774106 DOI: 10.1186/s13019-017-0671-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2017] [Accepted: 11/16/2017] [Indexed: 11/22/2022] Open
Abstract
Background Histopathological changes in the ascending aorta wall in patients with severe tricuspid aortic valve (TAV) stenosis were graded and correlated to echocardiographic parameters. Objective was to associate threshold echocardiographic values with structural defects in the ascending aorta providing a tool to improve decision-making process in cases when simultaneous aortic valve replacement (AVR) and ascending aorta replacement is considered. Methods Biopsies from 108 TAV stenosis patients subjected to AVR were graded into three grades according to severity of aortic wall changes. Echocardiographic parameters obtained preoperatively and correlated to grade, age, gender and risk factors, were diameters of ventriculo-aortic junction (AA), sinus Valsalva (SV), sinotubular junction (STJ), the largest diameter of the visualized ascending aorta (AscA) as well as indexes: sinus Valsalva (SVI), sinotubular junction (STJI), AscA/AA and STJ/AA. Results Two echocardiographic parameters portrayed grades with statistical significance: STJ (F = 5.417; p = 0.006 (p < 0.05)) and AscA (F = 3.924; p = 0.023 (p < 0.05)). By using multiple predictors in the setting of Regression analysis, statistically significant differences among grades were reached for AA, SV, STJ, AscA and SVI. With further ROC curves analysis, threshold values for different grades were recognized. Grade 2 is identified in patients with AscA > 3.3 cm, while Grade 3 is identified in patients with values of AscA > 3.5 cm, STJ > 2.9 cm and STJI > 1. Conclusions Hemodynamic stress induced by TAV stenosis leads to elastic lamellae disruption in the aortic wall. Those changes could be graded and correlated with echocardiographic parameters of the aortic root and ascending aorta, providing a tool for decision to replace ascending aorta concomitantly with AVR.

Abstract
Evidence indicates that patients with coarctation of the aorta (COA) suffer from increased cardiovascular morbidity and mortality in later life despite successful repair of COA in childhood. Systolic arterial hypertension is common, presenting in up to one-third of patients, and is regarded as the main driver of premature cardiovascular events in this group of patients. In this review, we discuss the prevalence and pathophysiology of hypertension in children following successful COA repair with no residual arch obstruction. The challenges in accurate blood pressure assessment at this early phase are considered and non-invasive measures of central blood pressure are discussed. Although the pathways for investigations in adults are well defined, we highlight the need to address the issues of cardiovascular surveillance in children and describe techniques which can provide complementary information for cardiovascular assessment in this group of patients such that timely treatment can occur.

Abstract
The number of women with congenital heart disease (CHD) at risk of pregnancy is growing because over 90% of them are grown-up into adulthood. The outcome of pregnancy and delivery is favorable in most of them provided that functional class and systemic ventricular function are good. Women with CHD such as pulmonary hypertension (Eisenmenger syndrome), severe left ventricular outflow stenosis, cyanotic CHD, aortopathy, Fontan procedure and systemic right ventricle (complete transposition of the great arteries [TGA] after atrial switch, congenitally corrected TGA) carry a high-risk. Most frequent complications during pregnancy and delivery are heart failure, arrhythmias, bleeding or thrombosis, and rarely maternal death. Complications of fetus are prematurity, low birth weight, abortion, and stillbirth. Risk stratification of pregnancy and delivery relates to functional status of the patient and is lesion specific. Medication during pregnancy and post-delivery (breast feeding) is a big concern. Especially prescribing medication with teratogenicity should be avoidable. Adequate care during pregnancy, delivery, and the postpartum period requires a multidisciplinary team approach with cardiologists, obstetricians, anesthesiologists, neonatologists, nurses and other related disciplines. Caring for a baby is an important issue due to temporarily pregnancy-induced cardiac dysfunction, and therefore familial support is mandatory especially during peripartum and after delivery. Timely pre-pregnancy counseling should be offered to all women with CHD to prevent avoidable pregnancy-related risks. Successful pregnancy is feasible for most women with CHD at relatively low risk when appropriate counseling and optimal care are provided.

Abstract
Marfan syndrome, bicuspid aortic valve, and/or coarctation of the aorta are associated with medial abnormalities of the ascending aortic or para-coarctation aorta. Medial abnormalities in the ascending aorta are prevalent in other type of patients with a variety of CHDs such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic left heart syndrome, and tetralogy of Fallot, encompassing a wide age range and may predispose to dilatation, aneurysm, and rapture necessitating aortic valve and root surgery. These CHDs exhibit ongoing dilatation of the aortic root and reduced aortic elasticity and increased aortic stiffness that may relate to intrinsic properties of the aortic root. These aortic dilatation and increased stiffness can induce aortic aneurysm, rapture of the aorta, and aortic regurgitation, but also provoke left ventricular hypertrophy, reduced coronary artery flow, and left ventricular failure. Therefore, a new clinical entity can be used to call this association of aortic pathophysiological abnormality, aortic dilation, and aorto-left ventricular interaction - "aortopathy".

Abstract
For the first time in 2017 adults with CHD was included in the World Congress of Pediatric Cardiology & Cardiac Surgery. With growing numbers and more complex patients reaching adulthood, there is a growing need for more attention to this subspecialty. Although survival is excellent and now over 90% of patients reach adulthood, many have residual problems and complications. Heart failure and arrhythmias are most commonly encountered. Life-expectancy is nearly normal for mild lesions, but remains reduced in moderate-complex lesions and re-interventions are often needed. As most patients want to live a normal life, sports participation and pregnancy become very important issues. Finally, although innovative treatments are being developed, including for end-stage heart failure, we have to refine strategies for optimal care, including during the end-stage lives of our patients. This article provides an overview of a selection of topics in the field of adults with CHD presented during the 2017 Seventh World Congress of Pediatric Cardiology & Cardiac Surgery (WCPCCS) in Barcelona.

Abstract
BACKGROUND The purposes of this study were to prospectively evaluate the histologic characteristics of the aortic wall of patients undergoing univentricular type of repair and compare the same with the findings observed in patients undergoing intracardiac repair of tetralogy of Fallot (TOF). PATIENTS AND METHODS Operatively excised full-thickness aortic wall tissue from 99 consecutive patients undergoing either intracardiac repair of TOF (group I; n=42) or univentricular repair (group II; n=57) were studied by light microscopy. Age at operation was 13 months to 28 years (mean 99.97±73.21months) for group I and 9 months to 25 years (mean 79.52±60.09) months for group II patients. RESULTS Dilatation of the ascending aorta was present in 85.7% patients with TOF and 91.2% patients with a univentricular heart. Seventeen (17.2%) aortic specimens were histologically normal and were used as normal controls (group I, n=5; group II, n=12). A lamellar count of less than 60 was associated with a sensitivity of 97.2% and a specificity of 66.7% in patients undergoing repair of TOF and a sensitivity of 84.6% and a specificity of 80% in patients undergoing univentricular type of repairs respectively. Patients undergoing intracardiac repair of TOF and those undergoing univentricular repair exhibited 23.67 times (15.91-147.40) and 8.48 times (3.62-15.84) increased risk of aortic dilatation respectively. CONCLUSIONS Our findings indicate the existence of significant elastic fragmentation, muscle disarray, medionecrosis and fibrosis involving the ascending aortic media in patients with a functionally univentricular heart and dilated aorta. These histopathological changes are similar to those encountered in patients with TOF and dilated aorta.

Abstract
BACKGROUND Hypertension following primary coarctation repair affects up to a third of subjects. A number of studies suggest that future hypertension risk is reduced if primary repair is performed at a younger age. OBJECTIVES The objective of this study was to evaluate the risk of future medical treatment for hypertension depending on age of primary coarctation repair. METHODS This study was carried out at a tertiary paediatric cardiology referral centre. Retrospective database evaluation of children aged 28 days and ⩽12 months), and children (>12 months). Main outcome measure is the need for long-term anti-hypertensive medication. The risk for re-coarctation was also evaluated. RESULTS A total of 87 patients were analysed: 60 neonates, 17 infants, 10 children. Among them, 6.7% neonates, 29.4% infants, and 40% children required long-term anti-hypertensive medications. Group differences were statistically significant (p=0.004). After adjustment for type of repair, the risk of long-term anti-hypertensive therapy was 4.5 (95% confidence interval 1.2-16.9, p=0.025) and 10.5 times (95% confidence interval 2.6-42.3, p=0.001) higher if primary repair was carried out in infancy and childhood, respectively, compared with neonates. Among all, 13 patients developed re-coarctation: 21.7% in the neonatal group, 5.9% in the infant group, and 20% in the child group. We could not demonstrate a significant difference between these proportions or calculate a reliable risk for developing re-coarctation. CONCLUSIONS Risk of medical treatment for hypertension was lowest when primary repair was carried out during the neonatal period, rising 10-fold if first operated on as a child. Knowing the likelihood of hypertension development depending on age of primary repair is useful for long-term surveillance and counselling.

Abstract
Objective Central systolic blood pressure (SBP) is a measure of arterial stiffness and strongly associated with atherosclerosis and end-organ damage. It is a stronger predictor of cardiovascular events and all-cause mortality than peripheral SBP. In particular, for children with congenital heart disease, a higher central SBP might impose a greater threat of cardiac damage. The aim of the study was to analyse and compare central SBP in children with congenital heart disease and in healthy counterparts. Patients and methods Central SBP was measured using an oscillometric method in 417 children (38.9% girls, 13.0 ± 3.2 years) with various congenital heart diseases between July 2014 and February 2017. The test results were compared with a recent healthy reference cohort of 1466 children (49.5% girls, 12.9 ± 2.5 years). Results After correction for several covariates in a general linear model, central SBP of children with congenital heart disease was significantly increased (congenital heart disease: 102.1 ± 10.2 vs. healthy reference cohort: 100.4 ± 8.6, p < .001). The analysis of congenital heart disease subgroups revealed higher central SBP in children with left heart obstructions (mean difference: 3.6 mmHg, p < .001), transpositions of the great arteries after arterial switch (mean difference: 2.2 mmHg, p = .017) and univentricular hearts after total cavopulmonary connection (mean difference: 2.1 mmHg, p = .015) compared with the reference. Conclusion Children with congenital heart disease have significantly higher central SBP compared with healthy peers, predisposing them to premature heart failure. Screening and long-term observations of central SBP in children with congenital heart disease seems warranted in order to evaluate the need for treatment.

Abstract
Patients with a bicuspid aortic valve (BAV) often have proximal aortic dilatation and systemic vascular dysfunction. We hypothesized that BAV patients would have different carotid artery structural and functional characteristics compared to tricuspid aortic valve (TAV) patients. In 28 patients with surgically confirmed BAV and 27 patients with TAV, intima media thickness (IMT), number of plaques, fractional area change (FAC), global circumferential strain (GCS), and standard deviation of CS (SD-CS) in both common carotid arteries were assessed using duplex ultrasound and velocity vector imaging (VVI). Patients with BAV were younger and had less co-morbidity, but showed a significantly larger ascending aorta (43.3 ± 7.5 vs. 37.0 ± 6.2 mm, p < 0.001) and a higher prevalence of aortopathy (61 vs. 30%, p = 0.021) than those with TAV. BAV patients showed a significantly lower IMT and fewer plaques. Although FAC and GCS were not significantly different between the two groups, they tended to be lower in the BAV group when each group was divided into three subgroups according to age. There was a significant age-dependent increase in IMT and decreases in FAC and GCS in the TAV group (p = 0.005, p = 0.001, p = 0.002, respectively), but this phenomenon was not evident in the BAV group (p = 0.074, p = 0.248, p = 0.394, respectively). BAV patients with aortopathy showed a higher SD-CS than those without aortopathy (p = 0.040), reflecting disordered mechanical function. In conclusion, BAV patients have different carotid artery structure and function compared with TAV patients, suggesting intrinsic vascular abnormalities that are less affected by established cardiovascular risk factors and more strongly related to the presence of aortopathy.

Abstract
OBJECTIVE Fontan circulations have obligatory venous hypertension, depressed cardiac output and abnormal arterial elastance. Ventriculovascular coupling is known to be abnormal, but the underlying mechanisms are poorly defined. We aim to describe the histopathological features of vascular remodelling encountered in the central arteries and veins in the Fontan circulation as a possible underlying pathological representation of abnormal ventriculovascular coupling. METHODS Postmortemvasculature (inferior vena cava (IVC), superior vena cava (SVC), pulmonary artery (PA), pulmonary vein (PV) and aorta) of 13 patients with a Fontan circulation (mean age 29.9 years, range 9.0-59.8 years) and 2 biventricular controls (ages 17.9 and 30.2 years) was examined. RESULTS IVC and SVC: Eccentric and variable intimal fibromuscular proliferation occurred in 11 Fontan subjects. There was variable loss of medial smooth muscle bundles with reciprocal replacement with dense collagenous tissue.PA: Similar intimal fibromuscular proliferation was seen; however, these intimal changes were accompanied by medial thinning rather than expansion, medial myxoid degeneration and elastic alteration.PV: The PVs demonstrated intimal fibroproliferation and disorganisation of the muscular media.Aorta: The aortic lamina intima was thickened, with associated fibromuscular proliferation and elasticisation. There was also moderate lymphocytic inflammation in the aortic wall. CONCLUSIONS Vascular architectural remodelling is common in Fontan patients. The central veins demonstrate profound changes of eccentric intimal expansion and smooth muscle replacement with collagen. The pulmonary demonstrated abnormal intimal proliferation, and aortic remodelling was characterised by intima lamina thickening and a moderate degree of aortic wall inflammation.

Abstract
BACKGROUND Aortic root dilatation (ARD) in congenital heart disease is related to aortic aneurysm, rupture, and dissection. This study aimed to investigate the factors associated with ARD in patients with surgically repaired ventricular septal defect (VSD). METHODS This cross-sectional study included 152 patients with surgically repaired VSD. Two definitions of ARD were used: (1) observed Valsalva diameter to body surface area (BSA) ratio >2.1 cm/m2 and (2) absolute value of Valsalva diameter ≥4.0 cm. Odds ratios (ORs) and 95% confidence intervals (CIs) of ARD presence were calculated using multivariate logistic regressions. RESULTS The prevalence of ARD ranged between 8.6% and 32.9%. Using the definition of observed aortic root diameter/BSA >2.1 cm/m2 , patients with nonsubarterial VSD type were more likely to have ARD (OR 5.65, 95% CI; 1.83-17.44, P=.003) than those with subarterial type, and patients with preoperative right- or noncoronary cusp prolapse (R/NCCP) were more likely to have ARD (OR 3.68, 95% CI; 1.20-11.23, P=.022) than patients without preoperative R/NCCP after adjustment for sex, age at repair (ie, shunt duration), VSD size, and postoperative follow-up period. Using the definition of absolute Valsalva diameter ≥4 cm, nonsubarterial VSD type and presence of R/NCCP were also significantly associated with ARD after adjustment for the same covariates. CONCLUSIONS Anatomical and morphological features (nonsubarterial type and presence of preoperative R/NCCP) are independently correlated with ARD in patients with VSD regardless of the different definitions of ARD. Patients with surgically repaired VSD may need careful monitoring for potential ARD development.

Abstract
It is challenging to evaluate aortopathy in congenital heart disease using conventional investigations such as brachial-ankle pulse wave velocity (baPWV). Therefore, we evaluated the cardio-ankle vascular index (CAVI), a dimension of the ascending aorta and plasma transforming growth factor-β1 (TGF-β1) level, in order to find novel noninvasive parameters of aortopathy in adults with repaired tetralogy of Fallot (TOF). Prospectively, we enrolled 42 consecutive adults with TOF (28 patients with repaired TOF were not on ARB, 8 patients with repaired TOF on ARB, 6 patients with no repair or only palliative repair) and 20 age-matched healthy controls. We measured CAVI, baPWV, plasma TGF-β1 level and a diameter of the ascending aorta using echocardiography. The mean age of repaired TOF without ARB were 31.9 ± 9.1 years. An aortic diameter of the ascending aorta, CAVI, and plasma TGF-β1 level were significantly higher in repaired TOF without ARB than those in controls, whereas baPWV did not differ. On a univariate analysis, CAVI, plasma TGF-β1 level and Rastelli procedure were important factors for an aortic diameter of the ascending aorta (r = 0.56, P < 0.01, r = 0.59, P < 0.01, r = 0.39, P < 0.05, respectively) in this population. There was no significant correlation with age, baPWV, NT-pro brain natriuretic peptide (BNP), repair age, shunt duration, aortic regurgitation or right aortic arch. On the other hand, patients with unrepaired or palliative TOF, who had obvious volume overload, showed no significant correlation with CAVI, baPWV or plasma TGF-β1 level. CAVI and plasma TGF-β1 level, not baPWV, correlate to aortopathy in adults with repaired TOF.

Abstract
Objective: To assess medium-term effects of treatment for mild to moderate recoarctation in an adult population. Design: We identified all patients who had coarctation repair between 1965 and 1985 in our institution. They were all (n = 156) invited to a thorough outpatient examination, which was accepted by 133. Eleven (median age 36 [28-53] years) were identified with isolated mild to moderate recoarctation and received reintervention. They comprise the patient population of the current study. We performed bicycle exercise testing, transthoracic echocardiography, magnetic resonance imaging, and 24-hour blood pressure monitoring before and 14 to 29 months after reintervention. Results: Compared to the values before reintervention, 24-hour blood pressures were reduced, but only significantly so for nighttime values. On echocardiography, wall thickness was reduced (1.2 ± 0.3 vs 1.1 ± 0.2, P > .05), and maximum flow velocity in the distal aortic arch decreased (2.8 ± 0.5 m/s vs 2.1 ± 0.4 m/s, P < .05). The invasive coarctation gradient was significantly reduced (15 ± 7 mm Hg vs 5 ± 9 mm Hg, P < .05), and the diameter at the coarctation site was increased (11 ± 3 mm vs 15 ± 3 mm, P < .05). Maximum achieved workload increased (182 ± 51 W vs 205 ± 65 W, P < .05). Cardiac symptoms were overall reduced. Conclusion: Reintervention was overall beneficial in increasing exercise capacity and reducing symptoms in the medium term, but the effects on established myocardial hypertrophy and blood pressures were less profound. Larger studies are needed in order to establish the definite role of reintervention for patients with milder recoarctation.

Abstract
OBJECTIVES This study examines the outcome and procedural outcomes of percutaneous stent angioplasty for aortic coarctation in patients with Turner syndrome (TS). BACKGROUND TS occurs in 1 in 2,500 live-born females and is associated with aortic coarctation. METHODS In this multicenter, retrospective cohort study, all patients with TS and a coarctation of the aorta, treated with percutaneous stent implantation were included. The procedural strategies were dictated by local protocols. Adverse events at short- and long-term follow-up and qualitative parameters concerning the stent implantation were assessed. RESULTS In the largest study to date of TS patients receiving aortic stents, a total of 19 patients from 10 centers were included. Twelve patients were treated for native and 7 for recurrent coarctation. Age at intervention was 16.9 (7-60) years (median; min-max). The coarctation diameter increased significantly from 8.0 mm (2-12) pre-intervention to 15.0 mm (10-19) post-intervention (P < 0.001). Three (15.8%) adverse events occurred within 30 days of the procedure, including two dissections despite the use of covered stents, one resulting in death. At long-term follow-up (6.5 years, min-max: 1-16), two additional deaths occurred not known to be stent-related. CONCLUSIONS Though percutaneous treatment of aortic coarctation in TS patients is effective, it is associated with serious morbidity and mortality. These risks suggest that alternative treatment options should be carefully weighed against percutaneous stenting strategies. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND The increased cardiovascular morbidity of adults with late repair of aortic coarctation (CoA) has been well documented. In contrast, successful CoA repair in early childhood has a generally good prognosis, though adverse vascular and ventricular characteristics may be abnormal, which could increase long-term risk. This study sought to perform a comprehensive analysis of aortic elasticity and left ventricular (LV) function in patients with aortic coarctation (CoA) using cardiovascular magnetic resonance (CMR). In a subgroup of patients, we assessed structure and function of the common carotid arteries to probe for signs of systemic vascular remodeling. METHODS Fifty-one patients (median age 17.3 years), 13.9 ± 7.5 years after CoA repair, and 54 controls (median age 19.8 years) underwent CMR. We determined distensibility and pulse wave velocity (PWV) at different aortic locations. In a subgroup, common carotid artery distensibility, PWV, wall thickness and wall area were measured. LV ejection fraction (EF), volumes, and mass were measured from short axis views. Left atrial (LA) volumes and functional parameters (LAEFPassive, LAEFContractile, LAEFReservoir) were assessed from axial cine images. RESULTS In patients distensibility of the whole thoracic aorta was reduced (p < 0.05) while PWV was only significantly higher in the aortic arch (p < 0.01). Distensibility of the descending aorta at the level of the pulmonary arteries and PWV in the descending aorta, both correlated negatively with age at CoA repair. LA volume before atrial contraction and minimal LA volume were higher in patients (p < 0.05). LAEFPassive and LAEFReservoir were reduced (p < 0.05), and LAEFReservoir correlated negatively with aortic arch PWV (p < 0.05). LVEF, volumes and mass were not different from controls. Carotid wall thickness and PWV were higher in patients compared to controls (p < 0.05). CONCLUSIONS Patients after CoA repair have impaired bioelastic properties of the thoracic aorta with impact on LV diastolic function. Reduced descending aortic elasticity is associated with older age at time of CoA repair. The remodeling of the common carotid artery in our sub-study suggests systemic vessel wall changes.

Abstract
Pulmonary autograft replacement (Ross procedure) is used as an alternative to prosthetic aortic valve replacement patients with aortic valve disease. There are limited data on incidence and risk factors for dilatation and dysfunction of the neo-aortic after the Ross procedure. Ross procedure was performed in 100 patients at our institution between 1993 and 2011. In 76 patients, complete follow-up data were available. Their median age at surgery was 16 (0.4-58) years (76 % males; 95 % with congenital aortic valve disease). Median follow-up duration was 5.2 years (0.3-16.0 years). We analyzed their clinical and echocardiographic follow-up to identify possible risk factors for neo-aortic root dilatation and dysfunction. Ross procedure included reduction plasty of the native ascending aorta in 25 % of patients. During follow-up, 21 patients (28 %) developed neo-aortic root dilatation, 38 patients (50 %) dilatation oft the native ascending aorta and 7 patients (9 %) at least moderate neo-aortic regurgitation. Univariate risk factors for neo-aortic root dilatation were preoperative aortic regurgitation (p = 0.04), concomitant reduction plasty of the ascending aorta (p = 0.009) and a longer duration of follow-up (p = 0.005). Younger age at surgery was associated with dilatation of the ascending aorta (p = 0.03). Reoperation on the neo-aortic root because of severe dilatation was necessary in 6 patients (8 %), where 2 patients had at least moderate neo-aortic root regurgitation. Neo-aortic root and aortic dilatation are common after the Ross procedure. This is often combined with neo-aortic valve dysfunction. Close follow-up of these patients is mandatory.

Abstract
OBJECTIVES The aim of this study was to evaluate the effectiveness of balloon angioplasty (BAP) for recurrent aortic coarctation (ReCoA) in infants comparing simple and complex type of aortic arch pathology (Norwood I procedure). BACKGROUND ReCoA is a known complication after cardiovascular surgery for coarctation of the aortic arch. METHODS AND RESULTS In a single center case study, we analyzed 20 infants undergoing BAP for ReCoA comparing simple (n = 10) and complex type of aortic arch pathology (n = 10). At catherization diameter of ReCoA stenosis was 3.2 ± 0.7 mm (mean ± SD) with short localized (11/20) or long hypoplastic stenosis (9/20) before and 4.8 ± 1.2 mm after BAP (P < 0.001). Invasive systolic pressure gradient was reduced from 27.5 ± 16.2 mmHg before to 5.1 ± 6.6 mmHg after BAP (P < 0.001), comparable in simple and complex type of ReCoA. At day 1 after catherization noninvasive systolic arterial blood pressure gradient was reduced from 20.2 ± 23.1 to 6.7 ± 9.9 mmHg (P < 0.001), respectively, calculated continuous wave Doppler echo gradient from 36.3 ± 22 to 16.8 ± 9.6 mmHg (P < 0.01). Complications were aortic arch dissection (1/20), discrete aortic arch aneurysm formation (1/20), pericardial effusion (1/20), and peripheral arterial thrombosis (4/20). At a mid-term follow up of 9.5 months (1-40) after BAP, 3 infants needed early surgical reintervention due to secondary ReCoA, all with long hypoplastic aortic arch segments, but simple type of aortic arch pathology. CONCLUSIONS At mid-term follow up, BAP remains an effective catheter intervention for ReCoA for infants with localized ReCoA, but not with long hypoplastic aortic arch segments, even in simple type of aortic arch pathology.

Abstract
Bicuspid aortic valve is often associated with lesions of the ascending aorta, which differ histologically from those in tricuspid valve patients. We undertook proteomic analyses to assess differences at the proteome level. Aortic samples were collected from 20 patients undergoing aortic valve and/or ascending aortic replacement; 9 had a bicuspid valve: 5 with aortic aneurysm (diameter > 50 mm) and 4 without dilation; 11 had a tricuspid valve: 6 with aortic aneurysm and 5 without dilation. Patients with histologically proven connective tissue disorders were excluded. Samples were dissected, solubilized, and subjected to 2-dimensional gel electrophoresis. Gel patterns showed an average of 580 protein spots in samples from bicuspid valve patients, and 564 spots in those with tricuspid valves. Comparative analysis revealed a correlation coefficient of 0.93 for protein expression in the bicuspid valve group compared to the tricuspid group. Three protein spots were significantly over-expressed and 4 were significantly down-regulated in the bicuspid group compared to the tricuspid group. The lowest correlation in protein expression was between non-dilated aortic tissues. These differences between aortic tissues of bicuspid and tricuspid valve patients suggest that mechanisms of aortic dilation might differ, at least in part, between such patients.

Abstract
Thoracic aortic dilation (AD) has commonly been described in conotruncal defects (CTDs), such as tetralogy of Fallot, double outlet right ventricle and transposition of the great arteries, and truncus arteriosus. Several theories for this have been devised, but fairly recent data indicate that there is likely an underlying histologic abnormality, similar to that seen in Marfan and other connective tissue disease. The majority of aortic dissection in the general population occurs after the age of 45 years, and there have been very few case reports of aortic dissection in CTD. Given advances in cardiac surgery and increasing survival over the past several decades, there has been rising concern that, as patients who have survived surgical correction of these defects age, there may be increased morbidity and mortality due to aortic dissection and aortic regurgitation. This review discusses the most recent developments in research into AD in CTD, including associated genetic mutations.

Abstract
To evaluate the association between aortic morphology and elasticity with aortic regurgitation in surgically corrected of tetralogy of Fallot (TOF) patients. We retrospectively identified 72 consecutive patients with surgically corrected TOF and 27 healthy controls who underwent cardiac MRI evaluation. Velocity-encoded cine MRI was used to quantify degree of aortic regurgitation (AR) in TOF patients. Ascending aorta diameters were measured at standard levels on MRA images. Aortic pulse-wave velocity (PWV) was quantified with MRI. Morphological and functional MRI variables were compared between groups of TOF patients with and without clinically relevant AR and controls. The association between aortic morphology and elasticity with the presence of AR was evaluated using univariate and multivariate logistic regression. The majority of TOF patients had only trace AR. Nine TOF patients (12 %) had an AR fraction higher than 15 %. Indexed aorta diameter at the sinotubular junction (p = 0.007), at the RPA level (p = 0.006), and low left ventricular ejection fraction (LVEF) (p = 0.015) showed the strongest associations with the presence of at least mild AR, which persisted after controlling for age and gender. Increased ascending aorta dimension is associated with AR in patients after repair of TOF. LVEF was also low in the group of patients with relevant AR compared to those without, suggesting even mild to moderate AR may contribute to LV dysfunction in these patients. Enlarged ascending aorta may be an indication for precise quantification of regurgitant fraction with MRI, since symptomatic patients may need aortic valve repair when moderate regurgitation is present.

Abstract
Despite major scientific advances in its prevention, treatment and care, hypertension remains a serious condition that might lead to long-term complications such as heart disease and stroke. The great majority of forms of hypertension eventually result from an increased vasomotor tone activity that is regulated by endothelial NOS (eNOS) in vascular endothelium. Here, we examined the effect of fucoidan on eNOS activation in human umbilical vein endothelial cells (HUVECs). We also examined the effects of functional components of Undaria pinnatifida fucoidan on blood pressure and vascular function in eNOS inhibition-induced hypertensive rats in vivo. Our results suggest that fucoidan increased nitric oxide production by activating eNOS and Akt phosphorylation, which could be impaired by Akt or eNOS inhibitors. In the hypertensive rat model, treatment of fucoidan resulted in potent and persistent reduction of high blood pressure (BP) even after drug withdrawal. Our results showed that the mechanisms might involve protection against vascular structure damage, enhanced endothelium-independent vascular function and inhibition of abnormal proliferation of smooth muscle cells, which are mediated by the Akt-eNOS signaling pathway. Moreover, fucoidan treatment reduced the vascular inflammation and oxidative stress control caused by iNOS expression. Together, these results support a putative role of fucoidan in hypertension prevention and treatment.

Abstract
The aortic root dilation in tetralogy of Fallot (TOF) is a long-term clinical problem, because a severely dilated aorta can lead to aortic regurgitation, dissection, or rupture, which can be fatal, necessitating surgical intervention. The details of the mechanism of aortic root dilation, however, are unclear. We have shown that aortic stiffness is increased in patients with repaired TOF, and may mirror the histological abnormality of elastic fiber disruption and matrix expansion. This aortic stiffness is related closely to the aortic dilation, indicating that aortic stiffness may be a predictor of outcome of aortic dilation. Furthermore, the aortic volume overload is a very important determinant of aortic diameter in TOF patients before corrective surgery. In addition, a chromosomal abnormality and the transforming growth factor-β signaling pathway, a major contributor to aortic dilation in Marfan syndrome, also affect this mechanism. In this way, aortic dilation in TOF patients is suggested to be a multifactorial disorder. The aim of this review was therefore to clarify the mechanism of aortic dilation in TOF, focusing on recent research findings. Studies linking histopathology, mechanical properties, molecular/cellular physiology, and clinical manifestations of aortic dilation facilitate appropriate treatment intervention and improvement of long-term prognosis of TOF.

Abstract
BACKGROUND Uncontrolled arterial hypertension is a frequent problem after successful repair of CoA and has been attributed to increased central sympathetic drive as well as a blunted baroreceptor reflex. RSD is a promising therapy to reduce central sympathetic drive and improve baroreflex sensitivity. METHODS 8 patients (age: 27±6 years) with previous surgical and/or percutaneous repair of CoA, absence of any relevant restenosis (invasive gradient across the site of previous treatment 3±4 mmHg) and resistant arterial hypertension (daytime SBP≥140 mmHg on 24 hour ambulatory blood pressure measurements [ABPM] in spite of the concurrent use of 3 antihypertensive agents of different classes or intolerance to BP medications) were included. Bilateral RSD was performed using the Symplicity Flex™ catheter (Medtronic, MN, USA). RESULTS RSD was successful in all patients with no procedural complications and no evidence for renal artery stenosis 6 months post procedure. From baseline to 6 month follow-up, RSD was followed by a significant reduction in average daytime systolic BP (150.4±7.8 to 143.1±8.0 mmHg; p=0.0117) as well as systolic BP throughout 24 h (146.8±7.3 vs. 140.5±7.8, p=0.04). CONCLUSION The BP reductions observed in these patients justify engaging in a larger clinical trial on the efficacy of RSD in this specific type of secondary hypertension and bares the hope that RSD might extend the currently very limited armory against arterial hypertension in young adults with previous repair of CoA.

Abstract
BACKGROUND Percutaneous closure of atrial septal defect (ASD) has become the preferred method in treatment of the majority of cases. The aim of this study was to evaluate the echocardiographic effects of percutaneous closure of secundum ASD in adults and assess which parameters predict good response to closure. DESIGN We prospectively included 42 patients with secundum ASD treated successfully with percutaneous device closure. All patients underwent transthoracic echocardiography examination with tissue Doppler imaging before, 24 hours after and within 3 months of intervention. Measurements of arterial stiffness were carried out using a Mobil-O-Graph arteriography system. RESULTS Remodeling of heart chambers occurred immediately and persisted at 3 months after ASD closure. Significant decreases were observed in right ventricle (RV) end-diastolic diameter, right atrium volume index, and tricuspid annular plane systolic excursion both after the procedure and at 3 months (P < .01 for all). The RV and left ventricle (LV) tissue Doppler-myocardial performance index demonstrated to decline during follow up (P = .0001). Significant correlations were found between pulse-wave velocity, augmentation index, pulmonary artery stiffness, and LV-RV tissue Doppler-myocardial performance index at third month. Linear regression analyses showed that pulse-wave velocity is the most effective parameter of LV and pulmonary artery stiffness is the most effective parameter of RV functional recovery, respectively, assessed by tissue Doppler-myocardial performance index. CONCLUSIONS Percutaneous closure of secundum ASD in adults has various sustained benefits on multiple echocardiographic parameters within 3 months. The changes in RV and LV function after device closure were significantly correlated with the degree of pulmonary artery stiffness and pulse-wave velocity, respectively.

Abstract
The aim of cardiovascular regeneration is to mimic the biological and mechanical functioning of tissues. For this it is crucial to recapitulate the in vivo cellular organization, which is the result of controlled cellular orientation. Cellular orientation response stems from the interaction between the cell and its complex biophysical environment. Environmental
biophysical cues are continuously detected and transduced to the nucleus through entwined mechanotransduction pathways. Next to the biochemical cascades invoked by the mechanical stimuli, the structural mechanotransduction pathway made of focal adhesions and the actin cytoskeleton can quickly transduce the biophysical signals directly to the nucleus. Observations linking cellular orientation response to biophysical cues have pointed out that the anisotropy and cyclic straining of the substrate influence cellular orientation. Yet, little is known about the mechanisms governing cellular orientation responses in case of cues applied separately and in combination. This review provides the state-of-the-art knowledge on the structural mechanotransduction pathway of adhesive cells, followed by an overview of the current understanding of cellular orientation responses to substrate anisotropy and uniaxial cyclic strain. Finally, we argue that comprehensive understanding of cellular orientation in complex biophysical environments requires systematic approaches based on the dissection of (sub)cellular responses to the individual cues composing the biophysical niche.

Abstract
Background Patients with hypoplastic left heart syndrome after a Norwood operation show dilatation and reduced distensibility of the reconstructed proximal aorta. Cardiac magnetic resonance imaging (CMR) and angiographic examinations indicate that the native descending aorta (DAo) is also dilated, but this has not been studied in detail. Methods and Results Seventy‐nine children with hypoplastic left heart syndrome in Fontan circulation (aged 6.3±3.2 years) and 18 control participants (aged 6.8±2.4 years) underwent 3.0‐tesla CMR. Gradient‐echo cine and phase‐contrast imaging was applied to measure cross‐sectional areas (CSAs), distensibility, pulse wave velocity, and the incremental elastic modulus of the thoracic aorta. CSA of the DAo in patients was also compared with published percentiles for aortic CSA. Patients had significantly larger CSA of the DAo at the level of pulmonary artery bifurcation (229.1±97.2 versus 175.7±24.3 mm/m2, P=0.04) and the diaphragm (196.2±66.0 versus 142.6±16.7 mm/m2, P<0.01). In 41 patients (52%), CSA of the DAo was >95th percentile level for control participants, and the incremental elastic modulus of the aortic arch and the DAo was higher than in patients with normal CSAs (arch: 90.1±64.3 versus 45.6±38.9 m/s; DAo: 86.3±53.7 versus 47.1±47.6 m/s; P<0.01). Incremental elastic modulus of the aortic arch and the DAo correlated with the CSA of the DAo (arch: r=0.5; DAo: r=0.49; P<0.01). Conclusions Children with hypoplastic left heart syndrome frequently show dilatation of their DAo associated with increased stiffness of the aortic arch. Higher aortic impedance increases the afterload of the systemic circulation and likely contributes to the burden of the systemic right ventricle.

Abstract
Patients with coarctation of the aorta (CoA) may develop hypertension and cerebrovascular accident (CVA) late after intervention, but the risk is still unclear. Therefore, we studied the epidemiologic profile from a general population aged <60 years to assess the relative risk. Our study population consisted of 126,943 patients with congenital heart disease (CHD) derived from Taiwan's National Health Insurance database from 2000 to 2010 (population 22,765,535). There were 2,295 patients with CoA (50.3% men) (prevalence: 0.116/1000). Associated cardiac lesions in 44% of the patients with CoA included ventricular septal defect (VSD; 23.3%), patent ductus arteriosus (7.5%), atrial septal defect (9.0%), and so forth. Hypertension occurred in 190 patients (8.3%) and was related to age, without associated VSD (odds ratio [OR] 5.90, 95% confidence interval [CI] 2.12 to 16.39, p = 0.001) and male gender (OR 1.59, 95% CI 1.09 to 2.30, p = 0.015). The incidence of hypertension increased rapidly in the young adulthood and was 1.36% in pediatric age group and 28.9% and 45.7% in age group 20 to 29 and 30 to 39, respectively. CVA occurred in 29 patients (1.67%), and the coexisting hypertension was the single predictor (OR 3.19, 95% CI 1.13 to 9.00, p = 0.029). Furthermore, in all patients with CHD, CoA was an independent risk factor for hypertension (OR 15.65, 95% CI 12.44 to 19.68, p <0.001) and CVA (OR 6.55, 95% CI 4.41 to 9.74, p <0.001). Comparing with non-CoA CHD patients, patients with CoA, particularly men, adult, and patients without VSD, have high risk of hypertension, which would further increase the risk of CVA. Early recognition and timely intervention for the hypertension in patients with CoA is mandatory.

Histopathology of aortic complications in bicuspid aortic valve versus Marfan syndrome: relevance for therapy? Heart Vessels 2015; 31:795-806. [PMID: 26129868 PMCID: PMC4850207 DOI: 10.1007/s00380-015-0703-z] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Accepted: 06/12/2015] [Indexed: 11/11/2022]
Abstract
Patients with bicuspid aortic valve (BAV) and patients with Marfan syndrome (MFS) are more prone to develop aortic dilation and dissection compared to persons with a tricuspid aortic valve (TAV). To elucidate potential common and distinct pathways of clinical relevance, we compared the histopathological substrates of aortopathy. Ascending aortic wall biopsies were divided in five groups: BAV (n = 36) and TAV (n = 23) without and with dilation and non-dilated MFS (n = 8). General histologic features, apoptosis, the expression of markers for vascular smooth muscle cell (VSMC) maturation, markers predictive for ascending aortic dilation in BAV, and expression of fibrillin-1 were investigated. Both MFS and BAV showed an altered distribution and decreased fibrillin-1 expression in the aorta and a significantly lower level of differentiated VSMC markers. Interestingly, markers predictive for aortic dilation in BAV were not expressed in the MFS aorta. The aorta in MFS was similar to the aorta in dilated TAV with regard to the presence of medial degeneration and apoptosis, while other markers for degeneration and aging like inflammation and progerin expression were low in MFS, comparable to BAV. Both MFS and BAV aortas have immature VSMCs, while MFS and TAV patients have a similar increased rate of medial degeneration. However, the mechanism leading to apoptosis is expected to be different, being fibrillin-1 mutation induced increased angiotensin-receptor-pathway signaling in MFS and cardiovascular aging and increased progerin in TAV. Our findings could explain why angiotensin inhibition is successful in MFS and less effective in TAV and BAV patients.

Abstract
Outlining specific protocols for the management of pediatric patients with Marfan syndrome has been challenging. This is mostly due to a dearth of clinical studies performed in pediatric patients. In Marfan syndrome, the major sources of morbidity and mortality relate to the cardiovascular system. In this review, we focus on aortic involvement seen in pediatric patients with Marfan syndrome, ranging from aortic dilatation to aortic rupture and heart failure. We discuss the histological, morphological, and pathogenetic basis of the cardiac manifestations seen in pediatric Marfan syndrome and use a specific case to depict our experienced range of cardiovascular manifestations. The survival for patients with Marfan syndrome may approach the expected survival for non-affected patients, with optimal management. With this potentiality in mind, we explore possible and actual management considerations for pediatric Marfan syndrome, examining both medical and surgical therapy modalities that can make the possibility of improved survival a reality.

Abstract
OBJECTIVE The aim of this study was to analyze the mid- and long-term outcome of single cusp replacement in patients with ventricular septal defect and aortic insufficiency. METHODS From September 2005 through March 2014, 172 patients underwent single cusp replacement and ventricular septal defect (VSD) closure. The median age was 19.5 years (range, 9 months to 67 years). Additional techniques were used to repair associated anomalies including sinus of Valsalva aneurysm, patent ductus arteriosus, patent foramen ovale, subaortic membrane, and intramural coronary artery. RESULTS One patient with large left ventricle (preoperative end-diastolic diameter: 9.8 cm) died after the procedure from incurable heart failure. Four patients required a second pump run for residual aortic insufficiency (AI) (two patients, 1.16%) and residual VSD (two patients, 1.16%). Four patients required re-exploration for postoperative bleeding or cardiac tamponade. Mean follow-up was 53.27 ± 25.37 months (median, 56.5 months; range, 3 to 104 months). Redo aortic valve surgery was performed in three patients. Three patients had moderate-severe AI during the following period without reoperation. There was no post-operative endocarditis. CONCLUSION Single cusp replacement can be safely used in patients with VSD-AI.

Abstract
Congenital diseases of the aorta tend to be obstructive when they present early in life, and aneurysmal when they present later in life. The latter group also tends to be associated with connective tissue disorders and with repaired conotruncal lesions. The indications for intervention in the aneurysm group are still in evolution but are clearly age- and lesion-dependant. Disorders such as Loeys-Dietz syndrome and Turner syndrome may deserve aggressive prophylactic surgery, as well as Marfan syndrome to a lesser extent. The natural history of the dilated aorta after repair of congenital heart lesions is probably more benign than de novo aneurysms and therefore should be treated conservatively.
