Familial Associations of Prevalence and Cause-Specific Mortality for Thoracic Aortic Disease and Bicuspid Aortic Valve in a Large-Population Database. Circulation 2023; 148:637-647. [PMID: 37317837 PMCID: PMC10527074 DOI: 10.1161/circulationaha.122.060439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Accepted: 05/23/2023] [Indexed: 06/16/2023]
Abstract
BACKGROUND Thoracic aortic disease and bicuspid aortic valve (BAV) likely have a heritable component, but large population-based studies are lacking. This study characterizes familial associations of thoracic aortic disease and BAV, as well as cardiovascular and aortic-specific mortality, among relatives of these individuals in a large-population database. METHODS In this observational case-control study of the Utah Population Database, we identified probands with a diagnosis of BAV, thoracic aortic aneurysm, or thoracic aortic dissection. Age- and sex-matched controls (10:1 ratio) were identified for each proband. First-degree relatives, second-degree relatives, and first cousins of probands and controls were identified through linked genealogical information. Cox proportional hazard models were used to quantify the familial associations for each diagnosis. We used a competing-risk model to determine the risk of cardiovascular-specific and aortic-specific mortality for relatives of probands. RESULTS The study population included 3 812 588 unique individuals. Familial hazard risk of a concordant diagnosis was elevated in the following populations compared with controls: first-degree relatives of patients with BAV (hazard ratio [HR], 6.88 [95% CI, 5.62-8.43]); first-degree relatives of patients with thoracic aortic aneurysm (HR, 5.09 [95% CI, 3.80-6.82]); and first-degree relatives of patients with thoracic aortic dissection (HR, 4.15 [95% CI, 3.25-5.31]). In addition, the risk of aortic dissection was higher in first-degree relatives of patients with BAV (HR, 3.63 [95% CI, 2.68-4.91]) and in first-degree relatives of patients with thoracic aneurysm (HR, 3.89 [95% CI, 2.93-5.18]) compared with controls. Dissection risk was highest in first-degree relatives of patients who carried a diagnosis of both BAV and aneurysm (HR, 6.13 [95% CI, 2.82-13.33]). First-degree relatives of patients with BAV, thoracic aneurysm, or aortic dissection had a higher risk of aortic-specific mortality (HR, 2.83 [95% CI, 2.44-3.29]) compared with controls. CONCLUSIONS Our results indicate that BAV and thoracic aortic disease carry a significant familial association for concordant disease and aortic dissection. The pattern of familiality is consistent with a genetic cause of disease. Furthermore, we observed higher risk of aortic-specific mortality in relatives of individuals with these diagnoses. This study provides supportive evidence for screening in relatives of patients with BAV, thoracic aneurysm, or dissection.

Bicuspid Aortic Valve in Children and Adolescents: A Comprehensive Review. Diagnostics (Basel) 2022; 12:diagnostics12071751.

Abstract
Bicuspid aortic valve (BAV) is the most common congenital heart defect. Prevalence of isolated BAV in the general pediatric population is about 0.8%, but it has been reported to be as high as 85% in patients with aortic coarctation. A genetic basis has been recognized, with great heterogeneity. Standard BAV terminology, recently proposed on the basis of morpho-functional assessment by transthoracic echocardiography, may be applied also to the pediatric population. Apart from neonatal stenotic BAV, progression of valve dysfunction and/or of the associated aortic dilation seems to be slow during pediatric age and complications are reported to be much rarer in comparison with adults. When required, because of severe BAV dysfunction, surgery is most often the therapeutic choice; however, the ideal initial approach to treat severe aortic stenosis in children or adolescents is not completely defined yet, and a percutaneous approach may be considered in selected cases as a palliative option in order to postpone surgery. A comprehensive and tailored evaluation is needed to define the right intervals for cardiologic evaluation, indications for sport activity and the right timing for intervention.

Abstract
ZusammenfassungAngeborene Herzfehler (AHF) werden teilweise erst im Erwachsenenalter diagnostiziert, entweder weil sie erst dann klinisch auffällig werden oder bei vorausgegangenen Untersuchungen übersehen wurden. Im Rahmen einer routinemäßigen transthorakalen Echokardiografie (TTE) können in der kardiologischen Praxis oder Klinik angeborene kardiale Anomalien leicht fehlgedeutet werden, da der Fokus in der Erwachsenenkardiologie überwiegend bei erworbenen Herzfehlern, einer Kardiomyopathie, Klappenerkrankungen oder einer systolischen oder diastolischen Dysfunktion liegt. Demgegenüber spielt eine thematische Auseinandersetzung mit AHF häufig eine nur untergeordnete Rolle, die Erwartungshaltung hinsichtlich angeborener kardialer Anomalien ist eher gering und die Sinne für mögliche AHF oft nicht geschärft. Dieser Artikel soll dazu beitragen, die Wahrscheinlichkeit des Erkennens eines AHF im Rahmen der TTE-Untersuchung zu erhöhen.

Abstract
Bicuspid aortic valve (BAV) is the most common congenital heart defect, found in up to 2% of the population and associated with a 30% lifetime risk of complications. BAV is inherited as an autosomal dominant trait with incomplete penetrance and variable expressivity due to a complex genetic architecture that involves many interacting genes. In this review, we highlight the current state of knowledge about BAV genetics, principles and methods for BAV gene discovery, clinical applications of BAV genetics, and important future directions.

Abstract
There is growing clinical need and interest to implement novel risk prediction tools in bicuspid aortic valve-associated proximal aortic disease, so-called bicuspid aortic valve aortopathy. Inherent limitations of the diameter-based risk stratification for adverse aortic events in bicuspid aortic valve aortopathy patients have recently been recognized. Therefore, alternative diagnostic tools and subsequent adjustments in the treatment guidelines are urgently needed. Herein, we summarize the current evidence on recent diagnostic developments to improve risk stratification in bicuspid aortic valve aortopathy, including circulating microRNAs as biomarkers to predict the progression of aortic disease.

Abstract
Aortic dilation is associated with congenital bicuspid aortic valve (BAV) disease, and its etiology is still not completely understood. The aim of this study is to provide further insight into aortic hemodynamics in a BAV population with different degrees of aortic dilation and regurgitation in comparison with a patient without pathology. A fluid–structure interaction (FSI) numerical approach is implemented regarding patient-specific geometries, where the aortic valves are defined by analytical orifices. Results show that, while the patient without pathology displays a typical hemodynamic behavior of flows in bends, BAV-related aortas present an accelerated flow along the outer aortic wall. Wall shear stress (WSS) overload in the outer curvature is observed, more marked in more dilated aortas. Moreover, helices in the ascending aorta are present in these patients, enhanced with greater dilation. These findings support the fact that hemodynamic factors play an important role in aortic dilation onset and development in BAV patients, caused by a prolonged exposure of the outer ascending aortic curvature to altered WSS. Besides, our results suggest that greater aortic regurgitation may be associated with abnormal WSS distributions in the ascending aorta during diastole, which can facilitate aortic root dilation.

Abstract
Introduction: Dilatation of the proximal aorta is often associated with an aortic valve disease (e.g. bicuspid aortic valve, aortic stenosis), so-called 'valve-related aortopathy.' The definition of optimal timing for surgical intervention in valve-related aortopathy remains incompletely clarified. The limited value of traditional diameter-based intervention criteria has been recognized and more sophisticated diagnostic tools are necessary.Areas covered: This article aims to give an overview on the most recent literature addressing the different forms of valve-related aortopathies and the optimal timing of surgical intervention. It highlights the valve morphotype-dependent (BAV vs TAV) and the valve lesion-dependent aortopathies (stenosis vs regurgitation) and outlines the current treatment options of those pathologies. Further, this review discusses novel serological and rheological markers, potentially helping in the decision-making process in valve-related aortopathy. Systematic literature searches were performed using PubMed and Embase up to July 2019.Expert opinion: The combination of serological biomarkers and quantitative rheological markers for transvalvular flow eccentricity might be an additional useful tool. A possible solution for the future could be a risk score which considers body-surface-adjusted aortic diameters, activity of certain circulating biomarkers, transvalvular flow patterns, possible connective tissue disorders, and the valve morphology to define an individualized treatment strategy.

Abstract
Abstract
Aims
To develop a cost-effectiveness model to address the outcome and economic implications of different thresholds for surgery in the management of aortopathy associated with bicuspid aortic valve disease.
Methods and results
A model was created from the perspective of an Australian healthcare funding agency. The index case was a 65-year-old with bicuspid aortic valve (BAV) and ascending aorta diameter of 5.0 cm. Health states were defined as: pre-operative with dilated aorta, post-operative without complications, post-complication, and death. The mean and variance of risks and transition probabilities were taken from a local surgical database and local costs and utilities of elective and urgent thoracic aortic surgery (AoS) with or without aortic valve replacement, with a sensitivity analysis based on a systematic review. Scenario analyses were provided for other aortic dimensions. Implications for survival, quality-adjusted life years (QALYs), and costs were calculated from healthcare delivery and economic perspectives. After 10 000 simulations for the reference case, the utility of watchful waiting (WW) exceeded that of elective AoS (13 ± 4 vs. 10 ± 5 QALY). The net monetary benefit was A$351 063 ± 304 965 with immediate AoS vs. 534 797 ± 198 570 with WW surveillance. The most important variables affecting effectiveness were utility value of survivors, rate of aortic growth, and probability of acute aortic event during WW.
Conclusions
This decision-analytic model informed by our practice, as well as a systematic analysis, shows that AoS in a BAV patient with aorta <5 cm diameter is costlier and less effective than WW.

Abstract
Bicuspid aortic valve (BAV) aortopathy remains of difficult clinical management due to its heterogeneity and further assessment of related aortic hemodynamics is necessary. The aim of this study was to assess systolic hemodynamic indexes and wall stresses in patients with diverse BAV phenotypes and dilated ascending aortas. The aortic geometry was reconstructed from patient-specific images while the aortic valve was generated based on patient-specific measurements. Physiologic material properties and boundary conditions were applied and fully coupled fluid-structure interaction (FSI) analysis were conducted. Our dilated aortic models were characterized by the presence of abnormal hemodynamics with elevated degrees of flow skewness and eccentricity, regardless of BAV morphotype. Retrograde flow was also present. Both features, predicted by flow angle and flow reversal ratios, were consistently higher than those reported for non-dilated aortas. Right-handed helical flow was present, as well as elevated wall shear stress (WSS) on the outer ascending aortic wall. Our results suggest that the abnormal flow associated with BAV may play a role in aortic enlargement and progress it further on already dilated aortas.

Abstract
Objectives To compare aortic size and stiffness parameters on MRI between bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) patients with aortic stenosis (AS). Methods MRI was performed in 174 patients with asymptomatic moderate-severe AS (mean AVAI 0.57 ± 0.14 cm2/m2) and 23 controls on 3T scanners. Valve morphology was available/analysable in 169 patients: 63 BAV (41 type-I, 22 type-II) and 106 TAV. Aortic cross-sectional areas were measured at the level of the pulmonary artery bifurcation. The ascending and descending aorta (AA, DA) distensibility, and pulse wave velocity (PWV) around the aortic arch were calculated. Results The AA and DA areas were lower in the controls, with no difference in DA distensibility or PWV, but slightly lower AA distensibility than in the patient group. With increasing age, there was a decrease in distensibility and an increase in PWV. After correcting for age, the AA maximum cross-sectional area was higher in bicuspid vs. tricuspid patients (12.97 [11.10, 15.59] vs. 10.06 [8.57, 12.04] cm2, p < 0.001), but there were no significant differences in AA distensibility (p = 0.099), DA distensibility (p = 0.498) or PWV (p = 0.235). Patients with BAV type-II valves demonstrated a significantly higher AA distensibility and lower PWV compared to type-I, despite a trend towards higher AA area. Conclusions In patients with significant AS, BAV patients do not have increased aortic stiffness compared to those with TAV despite increased ascending aortic dimensions. Those with type-II BAV have less aortic stiffness despite greater dimensions. These results demonstrate a dissociation between aortic dilatation and stiffness and suggest that altered flow patterns may play a role. Key Points • Both cellular abnormalities secondary to genetic differences and abnormal flow patterns have been implicated in the pathophysiology of aortic dilatation and increased vascular complications associated with bicuspid aortic valves (BAV). • We demonstrate an increased ascending aortic size in patients with BAV and moderate to severe AS compared to TAV and controls, but no difference in aortic stiffness parameters, therefore suggesting a dissociation between dilatation and stiffness. • Sub-group analysis showed greater aortic size but lower stiffness parameters in those with BAV type-II AS compared to BAV type-I.

Abstract
PURPOSE OF REVIEW The incidence of aortic dilation and acute complications (rupture and dissection) is higher in patients with a bicuspid aortic valve (BAV), the most frequent congenital heart defect.The present review focuses on the current knowledge in the genetics of BAV, emphasizing the clinical implications for early detection and personalized care. RECENT FINDINGS BAV is a highly heritable trait, but the genetic causes remain largely elusive. NOTCH1 is the only proven candidate gene to be associated with both familial and sporadic BAV. Other genes have been reported to be associated with BAV, but some of these associations may result from coexisting disease.The application of modern high-throughput technologies (next generation sequencing, genome-wide copy number and genome-wide methylation arrays) have begun to dissect the genetic heterogeneity underlying BAV as well as the diverse molecular pathways involved in the progression of BAV aortopathy. SUMMARY The clinical variability seen in BAV aortopathy, in terms of phenotype and natural/clinical history, suggests complex interactions between primary genetic defects, other modifier genes, epigenetic factors (DNA methylation or histone modifications, microRNA) and environmental factors (disturbed flow). Integrated, more comprehensive studies are needed for elucidating these connections to develop more individualized and accurate risk assessment methods.

Abstract
BACKGROUND A more aggressive posture toward resection of the dilated aorta has been advocated when associated with bicuspid aortic valve (BAV), based on the notion that aortic material properties are weaker in this setting despite scant data to support or refute this position. The hypothesis that histologic abnormality reflects aortic wall strength was tested by comparing aortas from patients with BAV and trileaflet aortic valve. METHODS Resected aortas associated with BAV (n = 60) and trileaflet aortic valve (n = 24) were compared with normal diameter aortas from patients undergoing cardiac transplantation (n = 16) by five histologic criteria: elastic fiber loss (graded 0-4), smooth muscle cell loss (graded 0-4), medial proteoglycan accumulation (graded 0-3), medial fibrosis (graded 0-3), and atherosclerosis (graded 0-3). Patients with known connective tissue disorders, systemic inflammatory conditions, dissection, or prior heart surgery were excluded. RESULTS Patients with BAV were a decade younger and more often had functional stenosis. The extent of elastic fiber loss, smooth muscle cell loss, medial fibrosis, and atherosclerosis was more severe in trileaflet aortic valve than BAV when considered across all diameters and when stratified to those between 4 and 5 cm. CONCLUSIONS More severe histologic abnormalities associated with trileaflet aortic valve compared with BAV, especially when stratified by diameter, do not support a more aggressive approach to surgical intervention for dilatation associated with BAV. Indeed, if based on histologic diagnosis alone, our findings are suggestive that the converse might be true. Additionally, the lack of correlation between aortic diameter and histologic abnormality in the setting of BAV highlights the inadequacy of diameter alone as a criterion for aortic resection.

Abstract
This paper presents a novel processing method for heart sound signal: the statistical time growing neural network (STGNN). The STGNN performs a robust classification by merging supervised and unsupervised statistical methods to overcome non-stationary behavior of the signal. By combining available preprocessing and segmentation techniques and the STGNN classifier, we build an automatic tool for screening children with isolated BAV, the congenital heart malformation which can lead to serious cardiovascular lesions. Children with BAV (22 individuals) and healthy condition (28 individuals) are subjected to the study. The performance of the STGNN is compared to that of a time growing neural network (CTGNN) and a conventional support vector (CSVM) machine, using balanced repeated random sub sampling. The average of the accuracy/sensitivity is estimated to be 87.4/86.5 for the STGNN, 81.8/83.4 for the CTGNN, and 72.9/66.8 for the CSVM. Results show that the STGNN offers better performance and provides more immunity to the background noise as compared to the CTGNN and CSVM. The method is implementable in a computer system to be employed in primary healthcare centers to improve the screening accuracy.

Abstract
BACKGROUND/OBJECTIVES Bicuspid aortic valve (BAV) is the most common congenital heart disorder, affecting up to 2% of the population. Involvement of aortic root and ascending aorta (aneurysm or, eventually, dissection) is frequent in patients with pathologic or normal functioning BAV. Unfortunately, there are no well-known correlations between valvular and vascular diseases. In VAR protocol, with a new strategy of research, we analysemultiple aspects of BAV disease through correlation between surgical, echo, histologic and genetic findings in phenotypically homogeneous outlier cases. METHODS VAR protocol is a prospective, longitudinal, multicenter study. It observes 4 homogeneous small groups of BAV surgical patients (15 patients each): isolated aortic regurgitation, isolated ascending aortic aneurysm, aortic regurgitation associated with aortic aneurysm, isolated aortic stenosis in older patients (>60years). Echo analysis is extended to first-degree relatives and, in case of BAV, genetic test is performed. Patients and relatives are enrolled in 10 cardiac surgery/cardiologic centers throughout Italy. CONCLUSIONS The aim of the study is to identify predictors of favorable or unfavorable evolution of BAV in terms of valvular dysfunction and/or aortic aneurysm. Correlations between different features could help in identification of various BAV risk groups, rationalizing follow-up and treatment.

Differing relationship between hypercholesterolemia and a bicuspid aortic valve according to the presence of aortic valve stenosis or aortic valve regurgitation. Gen Thorac Cardiovasc Surg 2015; 63:502-6. [PMID: 26033769 DOI: 10.1007/s11748-015-0561-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2013] [Accepted: 05/16/2015] [Indexed: 12/12/2022]
Abstract
OBJECTIVES To assess the difference in hyperlipidemia between patients with bicuspid aortic valve (BAV) and those with a normal aortic valve (NAV), and to compare aortic valve stenosis (AS), with aortic valve regurgitation (AR). METHODS Among 32 patients with BAV and 142 patients with NAV who underwent aortic valve replacement, 81 patients had AR and 91 patients had AS. The preoperative clinical characteristics were compared between the BAV and NAV patients. Patients with replacement of the ascending aorta were included, and those who underwent combined valvular surgery, coronary artery bypass grafting, or statin treatment were excluded. RESULTS The proportions of females patients (p = 0.42), patients with diabetes (p = 0.26) and patients on dialysis (p = 0.69) were similar in the two groups. Mean age was significantly lower, the mean diameter of the ascending aorta was significantly larger, and the rate of surgical intervention for the ascending aorta was significantly higher in the BAV group than in the NAV group (all p < 0.0001). The mean levels of low-density lipoprotein cholesterol (LDL) (p < 0.0001) and total cholesterol (TC) (p = 0.0003) were significantly higher in the BAV group than in the NAV group, in the analysis of only patients with AS, whereas these levels did not differ significantly between the groups, when only patients with AR were considered. CONCLUSION BAV with AS is associated with hypercholesterolemia. However, BAV with AR was not associated with hypercholesterolemia.

Abstract
BACKGROUND Bicuspid aortic valves are associated with aortic dilation and dissection. There is a paucity of prospective studies evaluating changes in aortic size over time in adult subjects with bicuspid aortic valves. METHODS A total of 115 subjects with asymptomatic bicuspid aortic valves were enrolled from 2003 to 2008 and followed prospectively over 5 years. Clinical and family histories, as well as transthoracic echocardiograms, were obtained at baseline, and echocardiograms were performed annually thereafter. RESULTS The mean age of subjects was 41.8 ± 12.8 years, and 61% were male. Ascending aortic size at baseline averaged 35.5 ± 5.6 mm and increased in 71.1% of subjects (mean, 0.66 ± 0.05 mm/y; range, 0.2-2.3 mm/y) over an average of 4.8 years. In 15.6% of subjects, the rate of change exceeded 1 mm/y. The average rate of ascending aortic dilation for all subjects was 0.47 ± 0.05 mm/y (P < .001). A family history of aortic valve disease was associated with progression in both unadjusted (P = .029) and logistic regression analyses adjusted for age, gender, and body surface area (odds ratio, 13.7; P = .021). Multivariate analysis did not find leaflet orientation or moderate to severe aortic valve dysfunction as independent predictors of aortic dilation. CONCLUSIONS We found that in subjects with bicuspid aortic valve, studied prospectively, there was an annual rate of ascending aortic dilation of 0.47 mm/y. In contrast to previous reports, leaflet orientation and aortic valve dysfunction were not independent predictors of aortic dilation. A family history of aortic valve disease was associated with a significantly increased risk of increasing ascending aortic size.

Abstract
The present study evaluated the value of black-blood high-resolution magnetic resonance imaging (HRMRI) for the visualization of intracranial atherosclerosis (ICAS) plaques. A total of 110 patients with cerebral artery or vertebrobasilar stenosis, vessel occlusion or a significantly weakened signal in black-blood magnetic resonance angiography (MRA; three-dimensional time-of-flight) were examined. Black-blood MRA was used to observe whether plaques were present in the abnormal vascular walls. Among the 110 patients with cerebral infarction, 16 cases presented with no significant abnormality of the lumen and walls, while plaques were observed in 94 cases. The plaques were categorized according to their signal characteristics, which resulted in the identification of four cases of type I and II plaques, 15 cases of type III, 26 cases of type IV and V, 23 cases of type VI, 11 cases of type VII, 14 cases of type VIII and one case of a mixed plaque. In summary, 3.0 T black-blood HRMRI was demonstrated to objectively exhibit characteristics of various types of ICAS plaques. Therefore, this imaging technique may be applied as a key method for the clinical non-invasive determination of ICAS plaques.

Abstract
Bicuspid aortic valve (BAV) is the most common adult congenital heart defect and is found in 0.5% to 2.0% of the general population. The term "BAV" refers to a heterogeneous group of disorders characterized by diverse aortic valve malformations with associated aortopathy, congenital heart defects, and genetic syndromes. Even after decades of investigation, the genetic determinants of BAV and its complications remain largely undefined. Just as BAV phenotypes are highly variable, the genetic etiologies of BAV are equally diverse and vary from complex inheritance in families to sporadic cases without any evidence of inheritance. In this paper, the authors discuss current concepts in BAV genetics and propose a roadmap for unraveling unanswered questions about BAV through the integrated analysis of genetic and clinical data.

Abstract
Bicuspid aortic valve (BAV) exhibits a clinical incline toward aortopathy, in which aberrant tensile and shear stress generated by BAV can induce differential expression of matrix metalloproteinases (MMPs) and their endogenous tissue inhibitors (TIMPs). Whether stenotic BAV, which exhibits additional eccentric high-velocity flow jet upon ascending aorta and further worsens circumferential systolic wall shear stress than BAV with echocardiographically normal aortic valve, can lead to unique plasma MMP/TIMP patterns is still unknown. According to their valvulopathy and aortic dilatation status, 93 BAV patients were included in the present study. Group A (n = 37) and B (n = 28) comprised severely stenotic patients with or without ascending aorta dilatation; Group C (n = 12) and D (n = 16) comprised echocardiographically normal BAV patients with or without ascending aorta dilatation. Plasma MMP/TIMP levels (MMP-1, -2, -3, -8, -9, -10, -13 and TIMP-1, -2, -4) were determined via a multiplex ELISA detection system in a single procedure. Among patients with isolated severe aortic stenosis, plasma levels of MMP-2 and -9 were significantly elevated when ascending aortic dilatation was present (p = 0.001 and p = 0.002, respectively). MMP-2, however, remained as the single elevated plasma component among echocardiographically normal BAV patients with dilated ascending aorta (p = 0.027). Multivariate analysis revealed that MMP-2 and MMP-9 could both serve as independent risk factor for aortic dilatation in the case of isolated severe stenosis (p = 0.003 and p = 0.001, respectively), and MMP-2 in echocardiographically normal patients (p = 0.002). In conclusion, BAV patients with isolated severe aortic stenosis demonstrated a distinct plasma MMP/TIMP pattern, which might be utilized as circulating biomarkers for early detection of aortic dilatation.

Clinical outcome, valve dysfunction, and progressive aortic dilation in a pediatric population with isolated bicuspid aortic valve. Pediatr Cardiol 2014; 35:803-9. [PMID: 24362596 DOI: 10.1007/s00246-013-0856-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2013] [Accepted: 12/03/2013] [Indexed: 12/01/2022]
Abstract
The aim of this study was to explore the medium-term clinical outcome and the risk of progression of aortic valve disease and aortic dilation in pediatric patients with isolated bicuspid aortic valve (BAV). 179 pediatric patients with isolated BAV were prospectively followed from January 1995 to December 2010. Patients with severe valve dysfunction at baseline were excluded. Clinical outcome included cardiac death, infective endocarditis, aortic complications, cardiac surgery and percutaneous valvuloplasty. Echocardiographic endpoints were: progression of aortic stenosis (AS) or regurgitation (AR) and progressive aortic enlargement at different levels of the aortic root, evaluated as z-score. The median age at diagnosis was 7.8 [2.7-12.0] years. After a median followup of 5.4 [2.3-9.2] years, all patients were alive. The clinical endpoint occurred in 4 (2.2 %) patients (0.41 events per 100 patient-years). A progression of AS and AR was observed in 9 (5.0 %) and 29 (16.2 %) patients, respectively. The z-scores at the end of follow-up were not significantly different from baseline at the annulus, Valsalva sinuses and sinotubular junction, whereas a slight increase was observed at the level of the ascending aorta (1.9 vs 1.5, p = 0.046). Significant progressive aortic dilation occurred in a minority of patients (10.6, 5.6, 9.5, and 19.0 % respectively). The clinical outcome in pediatric patients with isolated BAV is favourable and the progression of aortic valve dysfunction and aortic dilation is relatively slow. These findings may be taken into account to better guide risk assessment and clinical follow-up in these patients.

Effect of aortic aneurysm replacement on outcomes after bicuspid aortic valve surgery: validation of contemporary guidelines. J Thorac Cardiovasc Surg 2014; 148:2060-9. [PMID: 24755330 DOI: 10.1016/j.jtcvs.2014.03.027] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2013] [Revised: 02/27/2014] [Accepted: 03/17/2014] [Indexed: 01/28/2023]
Abstract
OBJECTIVE Bicuspid aortic valve (BAV) disease is associated with aortic dilatation and aneurysm (AN) formation. The American College of Cardiology/American Heart Association (ACC/AHA) 2006 guidelines recommend replacement of the ascending aorta for an aortic diameter (AD)> 45 mm in patients undergoing aortic valve replacement (AVR). We evaluated the outcomes of AVR and AVR with aortic replacement (AVR/AN). METHODS We retrospectively reviewed (2004-2011) the data from 456 patients with BAV and compared the morbidity and mortality between the AVR and AVR/AN groups and 3 subgroups: AVR with an AD<45 mm; AVR/AN with an AD of 45 to 49 mm; and AVR/AN with an AD of ≥50 mm. Propensity score matching was used to reduce bias. RESULTS Of the 456 patients, 250 (55%) underwent AVR and 206 (45%) AVR/AN, with 98% compliance with the current guidelines. The overall 30-day mortality was 0.9%. The AVR AD<45-mm group had adjusted short- and medium-term survival similar to that of the AVR/AN AD 45- to 49-mm and AVR/AN AD≥50-mm groups, with a 30-day mortality of 0.8%, 0%, and 1.9%, respectively (P=.41). The propensity score-matched AVR/AN AD≥50-mm group had significantly greater rates of reintubation than either the AVR AD<45-mm (P=.012) or AVR/AN AD 45- to 49-mm (P=.04) group and greater rates of prolonged ventilation (P=.022) than the AVR AD<45-mm group. No significant differences were found in reoperation or myocardial infarction among the subgroups. CONCLUSIONS In patients with undergoing AVR, no increase was seen in morbidity or mortality when adding aortic replacement with an AD of 45 to 49 mm, in accordance with the 2006 ACC/AHA guidelines, although the AVR/AN AD≥50-mm group had a greater risk of respiratory complications. Our findings indicate that compliance with the ACC/AHA guidelines is safe in select centers.

Ann Thorac Surg 2014; 97:1242-6. [PMID: 24518573 DOI: 10.1016/j.athoracsur.2013.12.022] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2013] [Revised: 12/02/2013] [Accepted: 12/18/2013] [Indexed: 10/25/2022]
Abstract
BACKGROUND Aortopathy associated with bicuspid aortic valve commonly involves the ascending aorta above the sinotubular ridge, but it may also affect sinus portions of the aorta. In some persons, the enlarged portion of the aortic root is limited to the noncoronary sinus. In such patients, we have spared the remaining portions of the aortic root by replacing the ascending aorta with a polyethylene terephthalate fiber (Dacron) graft and a tongue-shaped extension of the graft, thereby replacing the noncoronary sinus. In the present study, we evaluated late outcomes of this procedure, with specific attention to the fate of aortic tissue in the remaining sinuses. METHODS We reviewed the medical records of 1,756 patients with repair of ascending aortic aneurysms at Mayo Clinic from 1993 through 2012. Among the patients, 631 (35.9%) had bicuspid aortic valve, and in 79 (4.5%) of the patients, the noncoronary sinus was replaced along with the ascending aorta. RESULTS Associated aortic valve operations were performed in 70 patients; 15 had repair and 55 had aortic valve replacement. No early death occurred, but 3 patients died late after operation (5-year survival, 99%). There were 3 late reoperations, all because of native or prosthetic valve problems. Importantly, no instances occurred of aneurysm formation or aortic dissection related to the remaining aorta in the left and right aortic sinuses. CONCLUSIONS In patients with bicuspid aortic valve and aortic root enlargement related mainly to enlargement of the noncoronary sinus, limited replacement of the noncoronary sinus and ascending aorta is a safe and simple procedure that is durable in midterm follow-up.

Abstract
PURPOSE Aortic dissection is an infrequent but serious condition that often requires immediate operative intervention. We explore recent developments in the classification of aortic dissection and perioperative transesophageal echocardiography that assist with quantifying the severity of disease and facilitate its management. PRINCIPAL FINDINGS We describe the pivotal role of echocardiography in relation to key surgical considerations such as cannulation, aortic root surgery, perfusion in the aortic arch vessels, stenting in hybrid arch repair, and timing of preventative surgery. CONCLUSION Developments in the classification of aortic dissection have improved our perspective and understanding of the key presenting features that affect mortality. Improvements in patient outcome may be achieved in part by appropriately timed echocardiography-guided surgery.

Abstract
The risk of acute aortic events in patients with bicuspid aortic valve (BAV) disease is a controversial issue. The real risk of aortic dissection in patients with BAV disease is unknown. An indirect assessment of this risk, however, could be gained with a more detailed understanding of the pathogenesis of BAV aortopathy. There are two major issues that should be clarified before one addresses the question of aortic dissection risk in BAV patients. The first issue, when analysing the data from previous BAV cohorts, is to determine what stage of BAV disease was present in the described patient population. In particular, was the risk of aortic dissection in BAV patients determined before or after aortic valve replacement (AVR) surgery? The second issue to consider is the functional state of the pathological valve within the observed population. In particular, did patients predominantly suffer from BAV stenosis or BAV insufficiency? Unfortunately, the vast majority of published reports do not separate between the different BAV phenotypes, thereby complicating interpretation of the results. Considering these two important clinical variables (i.e. the stage of BAV disease and the functional phenotype), we herein aim to explain the inconsistency of the published data with regard to the risk of aortic dissection in patients with BAV disease.

Abstract
Recently, mutations in the SMAD3 gene were found to cause a new autosomal dominant aneurysm condition similar to Loeys-Dietz syndrome (LDS), mostly with osteoarthritis, called aneurysms-osteoarthritis syndrome (AOS). Our 3-year-old propositus underwent correction of an inguinal hernia at 3 months and substitution of the ascending aorta for pathologic dilation at 12 months of age. Family history reveals aortic dilation in his mother at 30 years, death due to aortic dissection of an 18-year-old maternal aunt, surgical replacement of the ascending aorta because of aneurysm in a maternal uncle at 19 years, postpartum death of the maternal grandmother at 24 years and surgical intervention because of thoracic aortic aneurysm in a brother of the propositus' grandmother at 54 years. The affected individuals present with several other signs of connective tissue disease, but the two adult patients evaluated revealed no radiologic evidence of osteoarthritis. Molecular testing of the TGFBR1 and TGFBR2 genes, involved in LDS, resulted negative, but analysis of SMAD3 disclosed the novel heterozygous loss-of-function mutation c.1170_1179del (p.Ser391AlafsX7) in exon 9 in all affected family members, confirming the diagnosis of AOS. SMAD3 mutations should be considered in patients of all ages with LDS-like phenotypes and negative TGFBR1/2 molecular tests, especially in the presence of aortic root or ascending aortic aneurysms, even though signs of early onset osteoarthritis are absent.

Abstract
The aim of our study was to compare the results of the TTE (transthoracic echocardiography) with the results obtained by the ECG-gated 64 slices CT during the followup of patients with bicuspid aortic valve (BAV), after aortic valve replacement; in particular we evaluated the aortic root and the ascending aorta looking for a new algorithm in the followup of these patients. From January 1999 to December 2009 our attention was focused on 67 patients with isolated surgical substitution of aortic valve; after dismissal they were strictly observed. During the period between May and September 2010, these patients underwent their last evaluation, and clinical exams, ECG, TTE, and an ECG-gated-MDCT were performed. At followup TTE results showed an aortic root of 36.7 ± 4 mm and an ascending aorta of 39.6 ± 4.8 mm. ECG- gated CT showed an aortic root of 37.9 ± 5.5 mm and an ascending aorta of 43.1 ± 5.2. The comparison between preoperative and postoperative TTE shows a significant long-term dilatation of the ascending aorta while the aortic root diameter seems to be stable. ECG-gated CT confirms the stability of the aortic root diameter (38.2 ± 5.3 mm versus 37.9 ± 5.5 mm; <0.0001) and the increasing diameter value of the ascending aorta (40.2 ± 3.9 mm versus 43.1 ± 5.2 mm; P = 0.0156). Due to the different findings between CT and TTE studies, ECG-gated CT should no longer be considered as a complementary exam in the followup of patients with BAV, but as a fundamental role since it is a real necessity.

Abstract
AIMS We compared flow and wall shear stress (WSS) patterns in the ascending aorta of individuals with either bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) using four-dimensional cardiovascular magnetic resonance (4D-CMR). BAV are known to be associated with dilation and dissection of the ascending aorta. However, the cause of vessel disease in patients with BAVs is unknown. Inborn connective tissue disease and also dilation secondary to increased WSS because of altered blood flow patterns in the ascending aorta are discussed as causes for dilation of the aorta. WSS can be estimated non-invasively by 4D-CMR. METHODS AND RESULTS Eighteen, otherwise, healthy individuals with functionally normal BAVs were compared prospectively with an age- and sex-matched control group of healthy individuals with TAV. Blood flow data were obtained by 4D-CMR visualization and WSS was calculated with specific software tools. Eighty-five per cent of the individuals with BAVs showed a high-grade helical flow pattern in the ascending aorta compared with 6% of the individuals with TAV. WSS in the ascending aorta was significantly altered in individuals with BAVs compared with TAV. CONCLUSION WSS and flow patterns in the ascending aorta in patients with BAVs without concomitant valve or vessel disease are significantly different compared with TAV. The significantly higher shear forces may have an impact on the development of aortic dilation in patients with BAVs.

Abstract
OBJECTIVES The scientific understanding of aortic dilation associated with bicuspid aortic valve (BAV) has evolved during the past 2 decades, along with improvements in diagnostic technology and surgical management. We aimed to evaluate secular trends and predictors of thoracic aortic surgery among patients with BAV in the United States. METHODS We used the 1998-2009 Nationwide Inpatient Sample, an administrative dataset representative of US hospital admissions, to identify hospitalizations for adults aged 18 years or more with BAV and aortic valve or thoracic aortic surgery. Covariates included age, gender, year, aortic dissection, endocarditis, thoracic aortic aneurysm, number of comorbidities, hospital teaching status and region, primary insurance, and concomitant coronary artery bypass surgery. RESULTS Between 1998 and 2009, 48,736 ± 3555 patients with BAV underwent aortic valve repair or replacement and 1679 ± 120 patients with BAV underwent isolated thoracic aortic surgery. The overall number of surgeries increased more than 3-fold, from 4556 ± 571 in 1998/1999 to 14,960 ± 2107 in 2008/2009 (P < .0001). The proportion of aortic valve repair or replacement including concomitant thoracic aortic surgery increased from 12.8% ± 1.4% in 1998/1999 to 28.5% ± 1.6% in 2008/2009, which mirrored an increasing proportion of patients with a diagnosis of thoracic aortic aneurysm. Mortality was equivalent for patients undergoing aortic valve repair or replacement with thoracic aortic surgery and those undergoing isolated aortic valve repair or replacement (1.8% ± 0.3% vs 1.5% ± 0.2%; multivariable odds ratio, 1.02; 95% confidence interval, 0.67-1.57), with decreasing mortality over the study period (from 2.5% ± 0.6% in 1998/1999 to 1.5% ± 0.2% in 2008/2009; multivariable odds ratio per 2-year increment, 0.89; 95% confidence interval, 0.81-0.99; P = .03). Total charges for BAV surgical hospitalizations increased more than 7.5-fold from approximately $156 million in 1998 to $1.2 billion in 2009 (inflation-adjusted 2009 dollars). CONCLUSIONS There was a marked increase in the use of thoracic aortic surgery among patients with BAV.

Abstract
Appreciation of the frequency of the congenitally malformed aortic valve has come about during the last 50 years, a period during which aortic valve replacement became a predictably successful operation. Study of patients at necropsy with either a congenitally unicuspid (1 true commissure) or bicuspid (2 true commissures) valve in whom no aortic valve operation has been performed has not been conducted during these 50 years, to our knowledge. We studied 218 patients at necropsy with congenitally malformed aortic valves: 28 (13%) had a unicuspid valve and 190 (87%), a bicuspid valve. Their ages at death ranged from 21 to 89 years (mean, 55 yr), and 80% were men. Of the 218 adults, the aortic valve functioned normally during life in 54 (25%) and abnormally in 164 (75%): aortic stenosis in 142 (65%), pure aortic regurgitation without superimposed infective endocarditis (IE) in 2 (1%), and IE superimposed on a previously normally functioning aortic valve in 20 (9%). IE occurred in a total of 31 (14%) of the 218 patients: involving a previously normally functioning valve in 20 (65%) and a previously stenotic valve in 11 (35%). Of the 218 patients, at least 141 (65%) died as a consequence of aortic valve disease (124 patients) or ascending aortic tears with or without dissection (17 patients). An estimated 1% of the population, maybe higher in men, has a congenitally malformed aortic valve. Data from this study suggest that about 75% of them will develop a major complication. Conversely, and encouragingly, about 25% will go through life without a complication.

Abstract
Dilation of the ascending aorta (AA) is common in patients with a bicuspid aortic valve. The natural history of the aortic root and AA and the risk factors for dilation have not been characterized in patients with congenital aortic stenosis (AS) treated with balloon valvuloplasty during childhood. The present study was performed to determine the prevalence of aortic dilation in patients with congenital AS before and up to 20 years after balloon valvuloplasty performed during childhood. In patients who underwent balloon valvuloplasty for AS at age ≤ 18 years from 1984 to 2005, the aortic diameter measurements before intervention and at 5-year intervals afterward were recorded and the Z scores calculated. Among 156 patients (median age 1.5 years at valvuloplasty), the AA Z scores were significantly larger than normal before intervention (median Z score 1.5) and at all follow-up points (all p <0.001). Using mixed modeling, with time as a categorical variable (before intervention, 5-year window, 10-year window, and so forth), the mean AA Z score was greater at all postvalvuloplasty points than before the intervention, with mean Z score increases of 1.20 at 5 years and 2.11 at 20 years (p <0.001). Moderate or greater aortic regurgitation early after valvuloplasty was associated with greater AA Z scores than mild or less aortic regurgitation, with a progressive difference over time. More significant residual AS after valvuloplasty was associated with lower AA Z scores over time. In conclusion, AA dilation is common in children with congenital AS and continues to progress over many years after balloon valvuloplasty.

Abstract
The mechanical properties of aortic wall, both healthy and pathological, are needed in order to develop and improve diagnostic and interventional criteria, and for the development of mechanical models to assess arterial integrity. This study focuses on the mechanical behaviour and rupture conditions of the human ascending aorta and its relationship with age and pathologies. Fresh ascending aortic specimens harvested from 23 healthy donors, 12 patients with bicuspid aortic valve (BAV) and 14 with aneurysm were tensile-tested in vitro under physiological conditions. Tensile strength, stretch at failure and elbow stress were measured. The obtained results showed that age causes a major reduction in the mechanical parameters of healthy ascending aortic tissue, and that no significant differences are found between the mechanical strength of aneurysmal or BAV aortic specimens and the corresponding age-matched control group. The physiological level of the stress in the circumferential direction was also computed to assess the physiological operation range of healthy and diseased ascending aortas. The mean physiological wall stress acting on pathologic aortas was found to be far from rupture, with factors of safety (defined as the ratio of tensile strength to the mean wall stress) larger than six. In contrast, the physiological operation of pathologic vessels lays in the stiff part of the response curve, losing part of its function of damping the pressure waves from the heart.

Abstract
OBJECTIVES Aneurysm diameter and growing rate does not represent a definite parameter for operation in bicuspid aortic valve (BAV), ascending aortic aneurysm and normal root patients. Thus, we investigated histological and immunohistochemical aspects of different segments of ascending aorta (precisely, aortic root without dilatation, aneurysmatic tubular portion, dissected ascending aorta) and genetic features of patients with BAV and ascending aorta complication (aneurysm or dissection). METHODS Aorta tissue samples of 24 BAV patients were examined. The patients comprised of 18 men and 6 women; the mean age was 54.2 ± 14.3 years. All patients underwent composite aortic root replacement (button Bentall operation). Multiple histological sections were prepared from each aortic specimen. The evaluated features included elastic fibre fragmentation, cystic medial change, smooth muscle cell necrosis, medial fibrosis, and the markers of medial apoptosis and the metalloproteinases. Furthermore, genetic risk factors were also investigated. RESULTS The same medial degenerative lesions in tissue samples of different aorta segments (precisely of aortic root without dilatation, and aneurysmatic ascending aorta portion) were observed. More significant associations between single nucleotide polymorphisms (-786T/C endothelial nitric oxide synthase enzyme, D/I angiotensin-converting enzyme, -1562C/T metalloproteinase-9 and -735C/T metalloproteinase-2) and aneurysm risk were detected in BAV patients than in controls. CONCLUSIONS Based on our histological and genetic data, we underline that a surgical approach in patients with BAV, ascending aortic aneurysm and normal root, should consider not only the diameter of the aneurysmatic aortic portion but also the histological features of the whole ascending aorta and the genetic risk profile.
