Abstract
OBJECTIVE Our goal was to use three dimensional (3D) strain analysis to evaluate myocardial function and ascending aorta elasticity changes in juvenile dermatomyositis (JDM). METHODS Between 2019 and 2021, 23 JDM patients and 20 healthy volunteers participated. Both groups underwent 2D and 3D strain analysis, assessing aortic stiffness using aortic distensibility, stiffness index, strain, and elastic modulus. RESULTS JDM patients had a median age of 13.3 ± 5.2 years, while controls had a median age of 13.8 ± 4.76 years. 3D strain analysis revealed significantly lower global longitudinal (GLS) and circumferential strain (GCS) in JDM patients compared to controls. Specifically, 3D GLS was notably reduced in patients (-28.1% vs. -31%, p = .047) compared to controls, and 3D GCS was also lower in patients (-27.5% vs. -30.5%, p = .019) compared to controls. Aortic strain and elastic modulus were significantly lower in JDM patients, while aortic stiffness index and distensibility showed no significant differences. Correlation analyses within the JDM group revealed a negative correlation between 3D GLS and age at diagnosis (r = -.561, p = .04), as well as a positive correlation between 3D GLS and both aortic strain (r = .514, p = .0001) and elastic modulus (r = .320, p = .03) in JDM patients. CONCLUSION Our study demonstrated a trend towards lower ejection fraction and strain in patients with JDM, along with increased aortic stiffness using 3D echocardiography. These findings suggest potential cardiovascular involvement in juvenile dermatomyositis, emphasizing the importance of comprehensive cardiac assessments in these patients.

J Am Coll Cardiol 2023; 82:448-464. [PMID: 37495282 DOI: 10.1016/j.jacc.2022.10.042] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 10/07/2022] [Accepted: 10/20/2022] [Indexed: 07/28/2023]
Abstract
Bicuspid aortic valve is the most common congenital heart disease and exposes patients to an increased risk of aortic dilation and dissection. Aortic dilation is a slow, silent process, leading to a greater risk of aortic dissection. The prevention of adverse events together with optimization of the frequency of the required lifelong imaging surveillance are important for both clinicians and patients and motivated extensive research to shed light on the physiopathologic processes involved in bicuspid aortic valve aortopathy. Two main research hypotheses have been consolidated in the last decade: one supports a genetic basis for the increased prevalence of dilation, in particular for the aortic root, and the second supports the damaging impact on the aortic wall of altered flow dynamics associated with these structurally abnormal valves, particularly significant in the ascending aorta. Current opinion tends to rule out mutually excluding causative mechanisms, recognizing both as important and potentially clinically relevant.

Abstract
To evaluate the prognostic value of aortic distensibility measured by cardiovascular magnetic resonance (CMR) as predictors of prophylactic aortic valve or aortic surgery in patients with bicuspid aortic valve (BAV). 110 patients with BAV were included. Distensibility of middle ascending aorta (AscAo) and proximal descending aorta (DescAo) at baseline was determined using CMR. The association between aortic distensibility and primary endpoint of aortic valve and/or aortic surgery was investigated with Cox proportional hazard regression analyses. The receiver operating characteristics curves (ROC) of the area under receiver-operator (AUC) and DeLong test were used to evaluate and compare the performance of different models. During a median follow-up of 66.5 months [IQR 13-75 months], 42 patients experienced surgical treatments. After adjusting for traditional risk factors, aortic distensibility (P = 0.003) and severe valve dysfunction (P < 0.001) were found significantly associated with aortic valve and/or aortic surgery. The model 2 (aortic distensibility and severe valve dysfunction) is slightly better in predicting primary endpoint than the model 1 (aortic diameter and severe valve dysfunction) (AUC: 0.893 vs. 0.842, P = 0.106). In BAV patients, aortic distensibility and severe valve dysfunction are valuable predictors for final aortic valve and/or aortic surgery.

Abstract
BACKGROUND Studies have found conflicting results concerning the left ventricular (LV) myocardial deformation properties in patients with normally functioning bicuspid aortic valves (BAVs). Whether the remodeling process of LV occurs independently in patients with BAV is a matter of debate. METHOD We searched PubMed, Embase, Cochrane library, and Web of Science for cohort studies aiming to assess LV function in adults with isolated BAV compared with tricuspid aortic valve (TAV) controls. Standard mean difference (SMD) was calculated from random-effects meta-analyses. RESULTS Eight cohort studies were included. There were significantly lower global longitudinal strain (GLS), global radial strain (GRS), global circumferential strain (GCS) in BAV than in TAV controls (GLS: SMD = 0.64, 95% CI: 0.35 to 0.92, P < .0001; GRS: SMD = -0.71, 95% CI: -1.09 to -0.32, P = .0003; GCS: SMD = 0.70, 95% CI: 0.41 to 0.98, P < .00001) and significantly higher left atrial volume index (LAVI) and E/e' in BAV than in TAV controls (LAVI: SMD = 0.50, 95% Cl: 0.12 to 0.88, P = .01; E/e': SMD = 0.54, 95% CI: 0.30 to 0.77, P < .00001). There was significantly higher Left ventricular mass index(LVMI) in BAV than in TAV controls (SMD = 0.51, 95% CI: 0.24 to 0.79, P = .0003). Left ventricular ejection fraction (LVEF) was not significantly different between BAV patients and TAV controls (SMD = 0.05, 95% CI: -0.16 to 0.26, P = .63). CONCLUSION The impairment of LV myocardial mechanics, including LV systolic, diastolic dysfunction and LV hypertrophy, is present in patients with normally functioning BAV. This might support the hypothesis that BAV is not only a valvular disease but also a myocardial disease.

Abstract
BACKGROUND Hypertension is the most common chronic disease and the most important risk factor for cardiovascular and cerebrovascular diseases. Atheroma and arteriosclerosis plays a key role in the occurrence and development of hypertension. The purpose of this study was to evaluate the elasticity of ascending aorta wall in patients with essential hypertension (EH) using M-mode echocardiography. MATERIALS AND METHODS We prospectively enrolled 54 EH patients and 51 healthy subjects (HS). They all underwent transthoracic echocardiography to measure ascending aorta inner diameters and brachial blood pressure measurement to calculate aortic elastic variables: compliance, distensibility, strain, stiffness index, and Peterson's elastic modulus. All participants also underwent bilateral carotid ultrasonographic examination. RESULTS There were no significant differences in age, sex, body mass index, blood lipids, blood glucose, and ascending aorta inner diameters between the two groups. We found neither intimal thickening nor plaque formation in the left or right carotid arteries in both groups. The aortic elastic properties were significantly impaired in EH patients compared with HS. CONCLUSIONS Echocardiography can be used for the noninvasive evaluation of ascending aorta wall elasticity as an early screening technique. Subclinical arteriosclerosis appeared to occur in the ascending aorta of patients with essential hypertension even though carotid ultrasonography was normal.

Abstract
Bicuspid aortic valve (BAV) is monitored by transthoracic echocardiography and computed tomography (CT) angiography. However, it does not have any early marker of disease progression. This study evaluated speckle-tracking echocardiography (STE) aortic and left ventricular (LV) strain prognostic values, their discriminative power, and their correlation with the degree of valvular regurgitation. We conducted a retrospective analysis of a prospectively enrolled cohort of 45 diagnosed with BAV and 20 gender and age matched controls. We performed 2D-STE aortic and LV strain analysis of the selected population. The cohort was followed-up during a median period of 19.9 months (IQR 12.9-25.2), and outcomes (hospital admission for heart failure (HF), aortic valve replacement (AVR), and death) were determined. The mean patient age was 46.6 ± 15.5 years and 80 % were male. LV indexed volumes and aortic diameter were higher in BAV patients. LV global longitudinal strain (GLS) was impaired (p < 0.001) and aortic GLS was significantly augmented (p = 0.027) in BAV patients. Aortic global circumferential strain (GCS) did not vary between groups. Aortic diameter was the best parameter related to BAV (AUC 0.92) and aortic GLS was best correlated with significant AR (AUC 0.76). AVR was the only outcome observed and its only predictor was indexed LV end-diastolic volume. BAV had impaired LV-GLS values. Aortic GLS was abnormally augmented in BAV patients, which might reflect higher aortic diameters that distorted strain calculations. STE aortic strain is related to AR but does not appear to be a reliable predictor of surgery in BAV patients, at 19 months.

Abstract
Heart disease has always been one of the important diseases that endanger health and cause death. Therefore, it is particularly important to understand left atrium reconstruction and atrial fibrillation before heart image processing. The purpose of this paper is to provide an important review of the mechanisms of left atrial remodeling (LAR) associated with atrial fibrillation (AF). LAR refers to the spectrum of pathophysiological changes in (i) atrial structure and physiological function, and (ii) electric, ionic, and molecular milieu of the LA, in response to stresses imposed by conditions such as hypertension, myocardial ischemia, autonomic denervation and congestive heart failure. The main mechanisms of LAR include electrical remodeling, structural remodeling, metabolic remodeling, autonomic remodeling, neurohormones and inflammation, and other influencing factors. LAR is not only the basic mechanism of AF and heart failure, but also the pathophysiological basis of its progression. In clinical practice, AF is the most common persistent arrhythmia, and is believed to be the result of a combination of mechanisms that have triggers and maintenance mechanisms, including spontaneous ectopic pacing and multiple wavelet reentry. While LA electrophysiological, structural, and ultra-structural changes trigger AF, in turn, AF alters the LA electrical and structural properties that promote its maintenance and recurrence. Chronic AF leads to extensive changes in atrial cellular substructures, including loss of myofibrils, accumulation of glycogen, changes in mitochondrial shape and size, fragmentation of sarcoplasmic reticulum, and dispersion of nuclear chromatin. Electrical remodeling and structural remodeling of the atria during AF, involving structural changes and functional impairment of the left atrium, can lead to serious decline in left ventricular function and severe heart failure. Therefore, LAR and AF are inter-activating phenomena, and the resulting complications can cause serious disabling and fatal events. In this paper, we present (i) the mechanisms of LAR, in the form of structural, electrical, metabolic, and neurohormonal changes, and (ii) their interactive roles in initiating and maintaining AF. These in-depth understanding of the atrial remodeling mechanisms can in turn provide useful insights into the treatment of AF and heart failure.

Abstract
Bicuspid aortic valve (BAV) patients are at increased risk of valve dysfunction and ascending aorta aneurysm. Imaging techniques are essential to establish diagnosis, identify complications and indicate surgical treatment. Transthoracic echocardiography (TTE) is the imaging technique of choice to diagnose BAV, valve morphotype and valvular dysfunction in clinical practice. However, it can be less precise in assessing the aortic root and proximal ascending aorta, and visualization of the mid-distal ascending aorta and the arch may be difficult in some adults where cardiac magnetic resonance (CMR) and computed tomography, using multiplanar reconstructions, are better at assessing aortic diameters. Although valvular dysfunction is very variable, almost half of the patients have more than mild aortic valve disease. TTE is the most effective and accurate test for evaluating the severity of valvular dysfunction and guiding appropriate management decisions. Aorta dilation is a common finding in patients with BAV. The pattern of aortic dimensions has been categorized in three aortic phenotypes: no-dilation phenotype, ascending aorta phenotype and root phenotype. Controversial data exist regarding the relationship between BAV morphology and aorta dilation phenotype. The assessment of aortic stiffness (measuring distensibility or the velocity of propagation of flow) has raised special interest in order to predict progressive aorta dilation. However, current data indicates that BAV aortas do not show altered stiffness compared to those associated with a tricuspid valve with a similar aorta size. Moreover, novel 4D-flow CMR sequences have been crucial in the evaluation of abnormal ascending aorta flow, showing that flow in the aorta of BAV patients is asymmetric and includes the formation of large vortices. Such flow abnormalities are thought to produce changes in wall shear stress which has been associated with extracellular matrix dysregulation. The key points to understand familial screening and the recommendations for establishing the follow-up and therapeutic management of BAV patients are exposed in the review. The main objective of this article is to review the advantages and limitations of the imaging techniques in the diagnosis and management of BAV and the best strategies in the use of multimodality imaging.

Abstract
Both essential hypertension (EH) and type 2 diabetes mellitus (T2DM) can impair the elasticity of the ascending aorta. We prospectively enrolled 42 patients with T2DM, 44 patients with EH, 45 patients with T2DM and EH (T2DM + EH), and 41 healthy subjects (HS). They all underwent transthoracic echocardiography to measure ascending aorta inner diameters and a brachial blood pressure measurement to calculate aortic elastic parameters (ie, compliance, distensibility, strain, stiffness index, and Peterson elastic modulus). We found that there were no significant differences as regard with age, sex, body mass index, blood lipids and glucose, carotid atherosclerosis, and ascending aorta inner diameters among the 4 groups. The aortic elastic properties were significantly impaired in T2DM, EH, and T2DM + EH patients compared with the HS, and more impaired in EH and T2DM + EH patients than T2DM patients; there were no significant differences between EH and T2DM + EH patients. Our findings suggest that both T2DM and EH can impair aortic elastic properties. Essential hypertension may play a more important role in the process of ascending aorta sclerosis in patients with T2DM + EH.

Abstract
PURPOSE To explore endothelial function and plasma matrix metalloproteinase-2 levels and their association with the size and elastic properties of the ascending aorta in the first-degree relatives (FDRs) with tricuspid aortic valve (TAV) of individuals with bicuspid aortic valve (BAV). METHODS Twenty-six patients with BAV without significant valvular dysfunction, 35 FDRs with TAV, and 29 matched healthy controls were analyzed. Two-dimensional echocardiography and high-resolution ultrasound were applied to evaluate the size and elasticity of the ascending aorta and the flow-mediated vasodilation (FMD) of the brachial artery in response to hyperemia. RESULTS The aortic diameter was larger in the BAV patients than in the FDRs and controls, and the aortic elastic properties showed larger decreases in the BAV patients. The FDRs had a larger aortic diameter and more impaired elastic properties than the controls. The BAV patients had a significantly lower FMD than the FDRs and controls (P < .001), while the FMD was lower in the FDRs than in the controls (P < .001). The plasma MMP-2 levels were significantly higher in the BAV patients than in the FDRs (P = .001) and controls (P < .001). Additionally, the FDRs had higher plasma MMP-2 levels than the controls (P < .001). Pearson correlation analysis revealed that the aortic diameter, distensibility, stiffness index, and strain were significantly associated with FMD and plasma MMP-2 levels. CONCLUSION Aortic enlargement and impaired elasticity in the FDRs with TAV were associated with impaired endothelial function and increased plasma MMP-2 concentrations.

Abstract
AIMS To compare the carotid stiffness and flow parameters by ultrafast ultrasound imaging (UF), in bicuspid aortic valve (BAV) patients to first-degree relatives (controls). METHODS BAV patients (n = 92) and controls (n = 48) were consecutively included at a reference center for BAV. Aortic valve and ascending aorta were evaluated by echocardiography. Common carotid arteries were evaluated by UF with a linear probe. A high frame rate (2,000 frames/s) was used to measure the pulse wave velocity (PWV). The arterial diameter change over the cardiac cycle was obtained by UF-Doppler imaging. This allowed us to measure the distensibility and the maximal rate of systolic distension (MRSD). The wall shear stress (WSS) was measured based on the same acquisitions, by analyzing blood flow velocities close to the carotid walls. RESULTS BAV patients had significantly larger aortic diameters (p < 0.001) at the Valsalva sinus and at the tubular ascending aorta but no larger carotid diameters. No significant differences were found in carotid stiffness parameters (distensibility, MRSD, and PWV), even though these patients had a higher aortic stiffness. Carotid stiffness correlated linearly with age and similar slopes were obtained for BAV patients and controls. No difference in carotid WSS was found between BAV patients and controls. CONCLUSION Our results clearly show that the carotid stiffness and flow parameters are not altered in case of BAV compared with controls.

Abstract
Aneurysms of the ascending aorta are frequently found in patients with a bicuspid aortic valve (BAV). This study assessed the risk factors of ascending aortic aneurysms and aortic elasticity in children with BAV. The study included 66 patients with no history of transcatheter intervention or surgical procedure who had been diagnosed with isolated BAV. Echocardiographic, blood pressure, and pulse measurements were obtained for all patients. The BAVs were classified as described by Sievers et al. (J Thorac Cardiovasc Surg 133:1226-1233, 2007), and aortic elasticity parameters were calculated using various formulas. The patients were divided into groups with and without cusp fusion, aortic stenosis (AS), aortic regurgitation (AR), or mixed lesions; the groups were then compared. The mean patient age was 10.43 ± 3.91 years; 15%he patients had no AS or AR, 33% had both AS and AR, 17% had AS alone, and 35% had AR alone. The most common type of BAV was type 5, and the ascending aorta z-scores were higher in children with mixed lesions and without a cusp fusion. Aortic distensibility (AD) was significantly higher, and the stiffness index was significantly lower, in patients with an ascending aorta z-score > 4. The ascending aortic z-scores were higher in the no-fusion and mixed lesion (AS + AR) groups, especially those originating from post-stenotic dilation due to AS. The AD was increased in patients with an ascending aorta z-score > 4. Patients should thus be monitored closely for dissection risk, and preventive medical treatment should be started early in those with AS without cusp fusion.

Abstract
Purpose of the Review Bicuspid aortic valve (BAV) is associated with a significant risk of development of aneurysm and dissection of the ascending thoracic aorta. Development of what is called BAV associated aortopathy is particularly heterogeneous with an uncertain prognosis and with no prognostic biomarkers except for the aortic diameter. This situation leads to an important variability of the therapeutic strategy of this aortopathy. By reviewing the literature on aortic stiffness in the case of BAV, we aimed at evaluating its potential prognostic role in the development of aortic dilatation. Recent Findings Studies evaluating aortic stiffness, with ultrasound or magnetic resonance imaging, converge toward the description of an increased segmental aortic stiffness in BAV patients regardless of age, diameter or aortic level, from the root to the arch. Even though there is a lack of longitudinal studies evaluating the progression of aortic dilatation, new data have recently shown the potential prognostic role of the maximal rate of systolic distension of the aortic wall with magnetic resonance imaging. Summary Although the use of aortic distensibility calculation is a simple evaluation of stiffness that could be easily transposed in daily practice, its interpretation remains uncertain. New arterial stiffening indicators seem more promising but need a stronger validation.

Abstract
Bicuspid aortic valve (BAV) disease is the most common congenital cardiac malformation associated with an increased lifetime risk and a high rate of surgically-relevant valve deterioration and aortic dilatation. Genomic data revealed that different genes are associated with BAV. A dominant genetic factor for the recent past was the basis to the recommendation for a more extensive aortic intervention. However very recent evidence that hemodynamic stressors and alterations of wall shear stress play an important role independent from the genetic trait led to more conservative treatment recommendations. Therefore, there is a current need to improve the ability to risk stratify BAV patients in order to obtain an early detection of valvulopathy and aortopathy while also to predict valve dysfunction and/or aortic disease development. Imaging studies based on new cutting-edge technologies, such us 4-dimensional (4D) flow magnetic resonance imaging (MRI), two-dimensional (2D) or three-dimensional (3D) speckle-tracking imaging (STI) and computation fluid dynamics, combined with studies demonstrating new gene mutations, specific signal pathways alterations, hemodynamic influences, circulating biomarkers modifications, endothelial progenitor cell impairment and immune/inflammatory response, all detected BAV valvulopathy progression and aortic wall abnormality. Overall, the main purpose of this review article is to merge the evidences of imaging and basic science studies in a coherent hypothesis that underlies and thus projects the development of both BAV during embryogenesis and BAV-associated aortopathy and its complications in the adult life, with the final goal to identifying aneurysm formation/rupture susceptibility to improve diagnosis and management of patients with BAV-related aortopathy.

Abstract
AimsTo compare the stiffness index in patients with bicuspid aortic valve (BAV) with first-degree relatives at each segment of the thoracic ascending aorta and to compare segmental analysis of aortic stiffness in association with BAV morphotype and function.Methods219 patients with BAV and 148 first-degree relatives (without BAV) were consecutively included at a reference centre for BAV. Ultrasound assessment of aortic and carotid stiffness was based on the variation of the segmental arterial diameters during the cardiac cycle and on blood pressure.ResultsWithout adjustment, the ascending aorta of patients with BAV seemed stiffer at each segment compared with controls (stiffness index at the sinus of Valsalva: 17.0±10.9 vs 8.9±6.1, p<0.001; tubular aorta: 20.4±31.3 vs 12.7±4.8, p=0.04). However, after adjustment on aortic diameter and age, only the sinus of Valsalva remained stiffer (p<0.001), whereas the tubular aorta no longer differed (p=0.610). In patients with BAV, aortic diameters were not influenced by the valve morphotype, except for the arch, which was more dilated in the case of 1- Non coronary sinus-Right subtype of BAV : 36.1 vs 27.6 mm, p<0.001. Aortic regurgitation was associated with an increase in aortic diameters at the sinus of Valsalva (p<0.001) and the tubular aortic levels (p=0.04).ConclusionStiffness increase at the sinus of Valsalva level is independent of aortic dilatation in patients with BAV, contrary to the classic relationship between stiffness and dilatation found on the other segments. The relationship between stiffness and clinical impact needs to be assessed at each aortic segment.

Abstract
Aortic valve dysfunction and aortic wall changes are well-known complications of bicuspid aortic valve (BAV) disease. The aim of the present study was to investigate whether a remodeling process of the left ventricle (LV) is present in patients with isolated BAV. Twenty-two consecutive patients (39 ± 15 years, 9 males) with clinically normal BAV and 18 age- and gender-matched control subjects (37 ± 10 years, 9 males) were included. Cardiovascular magnetic resonance (CMR) imaging was performed to evaluate LV function, aortic valve morphology, aortic orifice area, and ascending aorta (AA) dimensions. Tissue-tracking analysis was applied to assess LV systolic and diastolic myocardial mechanics in the longitudinal, circumferential, and radial direction and AA circumferential strain (CS). No significant difference was observed between BAV and controls regarding LV ejection fraction and LV mass index. Tissue-tracking analysis demonstrated that BAV patients had significantly impaired LV systolic and diastolic myocardial mechanics. BAV patients had also significantly lower AA CS compared with controls. At multivariate analysis, the presence of BAV was the only variable significantly and independently related to the impaired AA and LV systolic myocardial mechanics. In conclusion, LV myocardial deformation properties are impaired among BAV patients. The impairment of LV systolic mechanics observed in BAV patients appears to be related only to the congenital abnormality of the aortic valve itself.

Abstract
Arterial stiffness is a marker of cardiovascular damage and an independent predictor of major cardiovascular events, usually assessed via Carotid-Femoral Pulse Wave Velocity (cfPWV). The aim of this study was to test the feasibility and usefulness of aortic strain analysis using a simplified transthoracic echocardiography (TTE) speckle-tracking (ST) based method. 60 consecutive patients with normal blood pressure and aortic dimensions underwent TTE and cfPWV evaluation. Strain analysis was performed on the largest section of the ascending aorta (aA) with a dedicated software; three couples of speckles were identified within the anterior and posterior aortic wall and transverse segments connecting each couple traced. Peak ascending Aorta Strain (PaAS) was defined as the averaged peak percentage deformation of these segments during the cardiac cycle; aortic stiffness index β2 was defined as 100 × Ln(SBP/DBP)/PaAS. 17 patients were excluded for suboptimal TTE images. In the 43 analyzed individuals (male 58%, age 63 years) PaAS was 5.5 [3.7-8.6] % with excellent inter and intra observer reproducibility (ICC 95% for both). PaAS showed significant correlation with age (r = - 0.64), aA diameter (r = - 0.45), cfPWV (r = - 0.41), stroke volume (r = - 0.41) and heart rate (r = - 0.49). Age remained the only independent determinant of PaAS in a multivariate analysis. β2 (10.8 [5.9-15.0]) showed significant direct correlation with age, Pulse pressure, aA diameter and cfPWV. A simplified strain analysis of the ascending aorta is technically feasible with good reproducibility; PaAS and β2 index correlate well with established parameters of arterial stiffness and might represent a new index in evaluating vascular biomechanics.

Abstract
The aim of this study was to test whether enlarged size and impaired elastic properties of the ascending aorta are associated with impaired endothelial function and increases in plasma matrix metalloproteinase (MMP)-2 concentrations in patients with bicuspid aortic valve (BAV) without significant valvular dysfunction. The size and the elasticity of the ascending aorta and the flow-mediated vasodilation (FMD) in the brachial artery in response to hyperemia were evaluated with 2-D echocardiography and high-frequency linear ultrasound in 42 patients with BAV without significant valvular dysfunction and 30 age- and sex-matched healthy controls. In the BAV group, diastolic ascending aortic diameter (AoD) (32.1 ± 8.1 mm vs. 25.3 ± 3.6 mm, p <0.001) and aortic stiffness index (8.0 ± 5.3 vs. 4.0 ± 1.8, p <0.001) were significantly higher, and aortic strain (7.4 ± 3.6% vs. 11.1 ± 3.0%, p <0.001) and aortic distensibility (7.4 ± 4.1 × 10-6cm2/dyn vs. 11.1 ± 4.3 × 10-6cm2/dyn, p <0.001) were significantly lower than those in the control group. The BAV group also had lower FMD (6.5 ± 2.2% vs. 11.9 ± 2.7%, p <0.001) and higher plasma MMP-2 levels (226.7 ± 55.0 ng/mL vs. 177.0 ± 45.3 ng/mL, p <0.001) compared with the control group. In the BAV group, AoD, aortic strain, aortic stiffness index and aortic distensibility significantly correlated with FMD and MMP-2 (all p <0.05). The multivariable linear regression analysis further indicated that FMD and MMP-2 were independently associated with AoD (β = -1.1, p = 0.005, and β = 0.09, p <0.001, respectively). These findings suggest that enlarged size and impaired elastic properties of the ascending aorta are associated with endothelial dysfunction and elevated plasma MMP-2 level in patients with BAV without significant valvular dysfunction. FMD and plasma MMP-2 level are the significant and independent predictors of dilation of the ascending aorta in patients with BAV.

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.
