Warfarin use is associated with higher aortic bioprosthetic 18F-fluoride PET uptake.

BACKGROUND: Prevalence of bioprosthetic valve degeneration (BVD) is rising as the use of bioprosthetic aortic valves increases. Detecting early signs of BVD remains a challenge, with conventional imaging methods often failing to identify early deterioration stages. 18F-fuoride positron emission tomography (PET-CT) is an emerging technique that offers promising prospects to detect subclinical BVD. This study aimed to compare early PET parameters of fluoride uptake with echocardiographic hemodynamic parameters and compare outcomes according to anticoagulation in patients who received bioprosthetic valves. METHODS: This is a sub-study of the ANTIPRO clinical trial, which involved patients undergoing surgical aortic valve replacement (SAVR) with a porcine bioprosthesis and randomized them into anticoagulated and non-anticoagulated groups. Hemodynamic changes were assessed by transthoracic echocardiography (TTE), while 18F-fluoride PET-CT quantified fluoride uptake and divided the patients in two groups: high-uptake and low-uptake. Mean and maximum gradients by TTE at three years were compared between the two uptake groups. Fluoride uptake was also compared between the anticoagulated and control groups. RESULTS: We found no significant differences in transprosthetic gradients between high-uptake(21.4 ± 8.6 mmHg) and low-uptake(17.3 ± 11.2 mmHg.p = 0.244) PET-defined groups in this specific timeframe. Notably, anticoagulated patients exhibited significantly risk of higher fluoride uptake(OR = 4.34;95%CI:1.04-18.21.p = 0.045). CONCLUSIONS: No association was found between fluoride uptake and hemodynamic evaluation. Anticoagulation was associated with higher fluoride uptake. These findings highlight the emerging role of PET-CT in studying bioprosthetic aortic valves and emphasize the need for extended follow-up to evaluate the impact of anticoagulation on valve degeneration.

The Association Between Ascending Aortic and Left Ventricular Dimensions in Patients After Aortic Valve Replacement.

INTRODUCTION: Aortic valve replacement (AVR) is often recommended for patients with severe aortic stenosis or chronic aortic regurgitation. These conditions result in remodeling of the left ventricle, including increased interstitial fibrosis that may persist even after AVR. These structural changes impact left ventricular (LV) mechanics, causing compromised LV diameter to occur earlier than reduced LV ejection fraction (LVEF). The aim of this study was to examine the effect of left ventricular end-diastolic diameter (LVEDD) and its role in aortic expansion one year after AVR. METHODS: Sixty-three patients who underwent AVR were evaluated. All patients underwent standard transthoracic echocardiography, which included measurements of the ascending aorta, aortic root, LVEF, and LVEDD before the surgery and one year postoperatively. Correlations between these variables were calculated. RESULTS: All patients underwent AVR with either a mechanical or biological prosthetic aortic valve. Following AVR, there was a significant decrease in the dimensions of the ascending aorta and aortic root (both P=0.001). However, no significant changes were observed in LVEDD and LVEF. Correlations were found between the preoperative ascending aortic size and the preoperative and one-year postoperative LVEDD (r=0.419, P=0.001 and r=0.320, P=0.314, respectively). Additionally, there was a correlation between the postoperative ascending aortic size and the preoperative and one-year postoperative LVEDD (r=0.320, P=0.003 and r=0.136, P=0.335, respectively). CONCLUSION: The study findings demonstrate a significant correlation between the size of the aortic root and ascending aorta, before and after AVR. Additionally, a notable correlation was observed between postoperative LVEDD and the size of the aortic root.

Low-Flow, Low-Gradient Severe Aortic Stenosis in patients with preserved or reduced ejection fraction: a systematic literature review.

OBJECTIVES: A systematic review of the literature was conducted to analyze the current evidence on low-flow, low-gradient severe aortic stenosis. This analysis aimed to differentiate between subgroups of patients with reduced and preserved left ventricular ejection fraction (LVEF). METHODS: After conducting a systematic literature review, 35 observational studies were included. Out of these, 28 were prospective and 7 retrospective. The studies that included a mortality risk stratification of low-flow, low-gradient aortic stenosis (LF- LG AS) with both preserved and reduced LVEF were reviewed. RESULTS: The importance of considering multiple clinical and echocardiographic variables in diagnostic evaluation and therapeutic decision-making was highlighted. CONCLUSIONS: LF- LG AS, in any of its subgroups, is a common and challenging valve lesion. A careful assessment of severity and, in specific scenarios, a thorough reclassification is important. More high-quality studies are required to more precisely define the classification and prognosis of this entity.

Use of transillumination echocardiography in the assessment and diagnosis of bicuspid aortic valve.

Bicuspid aortic valve is the most common congenital heart defect. Transthoracic echocardiogram is the initial tool to assess and diagnose this condition, however, transesophageal echocardiogram with 3D modalities, including transillumination have a better anatomical and functional evaluation of the valve, allowing to classify the bicuspid aortic valve according to the position of the raphe and assess the main vessels for complications or exclude other cardiovascular diseases.

Ozaki Procedure Plus Aortic Annular Enlargement in an Extremely Narrow Aortic Annulus: A Surgical Challenge.

We report a 19-year-old woman with a history of percutaneous aortic valve (AV) balloon valvuloplasty 3 years ago. She was admitted with severe symptomatic AV stenosis with narrow aortic annulus. We decided to perform AV reconstruction with autologous pericardium. However, surgical findings revealed a very narrow AV annulus with a unicuspid valve; therefore, an AV enlargement was added.

Zero-contrast imaging for the assessment of transcatheter aortic valve implantation in candidates with renal dysfunction.

BACKGROUND: Candidates for transcatheter aortic valve implantation (TAVI) are currently evaluated using computed tomography angiography and invasive cardiac catheterization as an essential part of case selection and pre-procedure interventional planning. However, both imaging methods utilize iodinated agents, which may cause contrast-induced nephropathy, particularly in patients with baseline renal dysfunction. This study aimed to describe a zero-contrast imaging protocol for pre-TAVI evaluation in patients with advanced renal impairment. METHODS: The pre-TAVI zero-contrast scheme consisted of the following multi-modality combinations: (1) gadolinium-free magnetic resonance imaging (three-dimensional navigator-echo with electrocardiogram-gated steady-state free-precession series); (2) iodinated-free multislice computed tomography electrocardiogram-gated; (3) lower limb arterial duplex scan ultrasound; and (4) transesophageal echocardiography. Ultimately, TAVI was performed for those deemed good candidates, and contrast was allowed during the intervention; however, operators were strongly advised to utilize the least volume possible of iodinated agents. This pilot survey included ten patients with symptomatic aortic stenosis and renal dysfunction who underwent zero-contrast multi-modality imaging. RESULTS: All the patients ultimately underwent TAVI. The intervention was successful in all cases, without ≥ moderate residual aortic regurgitation, prosthesis embolization, annulus rupture, major vascular complications, stroke, or death during index hospitalization. The creatinine clearance remained stable throughout the observation period (baseline: 26.85 ± 12.55 mL/min; after multi-modality imaging: 26.76 ± 11.51 mL/min; post-TAVI at discharge: 29.84 ± 13.98 mL/min; p = 0.3 all). CONCLUSION: The proposed contrast-free imaging protocol appears to be a promising clinical tool for pre-TAVI evaluation in patients with severe renal dysfunction.

[Endovascular aortic replacement in a patient with bicuspid aortic valve disease]. / Reemplazo endovascular aórtico en un paciente con enfermedad de válvula aórtica bicúspide.

A 49-year-old male with a history of left ventricular systolic function dilated cardiomyopathy and severe symptomatic bicuspid aortic stenosis recently diagnosed (syncope, chest pain and dyspnea) was admitted to the coronary care unit. During hospitalization, he developed cardiogenic shock requiring double inotropic support. High surgical risk and an elevated chance of graft rejection contraindicated surgical replacement or heart transplant. We performed a transcatheter aortic valve replacement with a favorable evolution.

Un varón de 49 años ingresó en la unidad de cuidados coronarios, con antecedentes de miocardiopatía dilatada, con función sistólica del ventrículo izquierdo gravemente deteriorada y estenosis aórtica grave de origen bicúspide, sintomático para síncope, ángor y disnea de reciente diagnóstico. Durante la internación evolucionó con shock cardiogénico que requirió doble soporte inotrópico. Por presentar alto riesgo quirúrgico y elevada probabilidad de rechazo ante un eventual trasplante cardiaco, según sus estudios de histocompatibilidad, se procedió al reemplazo transcatéter de la válvula aortica, con evolución favorable.

Outcomes of reoperative aortic root surgery.

OBJECTIVE: The study objective was to determine the impact of reoperative aortic root replacement on short-term outcomes and survival. METHODS: This was a retrospective study of aortic root operations from 2010 to 2018. All patients with a complete aortic root replacement were included, and patients undergoing valve-sparing root replacements were excluded. Patients were dichotomized by first-time sternotomy versus redo sternotomy, which was defined as having had a prior sternotomy for whatever reason. Within the redo sternotomy group, reoperative aortic root replacements were identified, being defined as a complete aortic root replacement in patients with a prior aortic root replacement; 1:1 nearest neighbor propensity matching was used to compare outcomes across groups. Kaplan-Meier survival estimates were generated and compared using log-rank statistics. RESULTS: A total of 893 patients undergoing complete ARR were identified, of whom 595 (67%) underwent first-time sternotomy and 298 (33%) underwent redo sternotomy. After matching, postoperative outcomes were similar for the first-time and redo sternotomy groups, including operative mortality. Redo sternotomy was not associated with reduced survival after aortic root replacement compared with first-time sternotomy (P = .084), with 5-year survival of 73.7% for first-time sternotomy and 72.9% for redo sternotomy. In the redo sternotomy group (n = 298), 69 (23%) were reoperative aortic root replacements and 229 (77%) were first-time aortic root replacements. After matching, postoperative outcomes were similar for the first-time and reoperative aortic root replacement groups, including operative mortality. Reoperative aortic root replacement was not associated with reduced survival, compared with first-time aortic root replacement (P = .870), with 5-year survival of 67.9% for first-time aortic root replacement and 72.1% for reoperative aortic root replacement. CONCLUSIONS: Reoperative aortic root replacement can be performed safely and provides similar survival to first-time aortic root replacement.

Quadricuspid Aortic Valve with Ruptured Sinus of Valsalva Aneurysm: a Case Report.

Quadricuspid aortic valve (QAV) and sinus of Valsalva aneurysm (SVA) are rare congenital anomalies. We report an elderly patient with QAV associated with a ruptured SVA to the right atrium. Transthoracic echocardiographic and computed tomographic images are presented. We emphasize the important role of computed tomography angiography in establishing and confirming the diagnosis and facilitating treatment planning. The patient was successfully operated by a minimally invasive approach.

Gender Differences and Outcomes of Hypoattenuated Leaflet Thickening (HALT) Following Transcatheter Aortic Valve Replacement: A Meta-analysis of Randomized and Cohort Studies.

Subclinical leaflet thrombosis is characterized by hypoattenuated leaflet thickening (HALT) after transcatheter aortic valve replacement (TAVR) on computed tomography. However, given the low incidence of HALT after TAVR, the clinical significance of HALT is still being investigated. We sought to generate a more reliable estimate of the risk factors and adverse outcomes associated with HALT after TAVR by pooling data from randomized trials and cohort studies. PubMed/Medline database was systematically searched from inception until November 24, 2021, using the following terms: ("hypoattenuated leaflet thickening" and "transcatheter aortic valve replacement") and ("Subclinical leaflet thrombosis" and "transcatheter aortic valve replacement"). A random effects model meta-analysis was conducted using Mantel-Haenszel odds ratios (ORs) and the associated 95% confidence intervals (CIs), mean difference and the associated 95%. Ten studies with a total of 1462 patients were included, with follow-up ranging between 4 months and 3 years. HALT occurred in 14.4% of the patients undergoing TAVR. HALT was not associated with increased risk of stroke/TIA (OR 1.38; 95% CI [0.61-3.11]; I2=0%) or increased risk of all-cause mortality (OR 0.67; 95% CI [0.25-1.80]; I2=0). HALT was associated with a greater post-procedural mean aortic valve gradient (mean difference 2.31 mmHg; 95% CI [0.27, 4.35]; I2=71%). Interestingly, there was a trend of higher risk of HALT in men (OR 1.37; 95% CI [0.82-2.30]; I2=44%) while there was a trend towards lower risk of HALT in the presence of CKD (OR 0.76; 95% CI [0.49-1.19]; I2=0%); these trends did not reach statistical significance. This meta-analysis shows that the occurrence of HALT following TAVR is associated with a greater post-procedural mean aortic valve gradient but no excess risk of death or cerebrovascular events. The clinical significance of this higher post-procedural mean aortic valve gradient is uncertain and requires further investigations.

Anatomical and Clinical Factors Associated With Valvulopathy and Aortopathy in Mexican Patients With Bicuspid Aortic Valves.

The bicuspid aortic valve (BAV) is associated with significant aortic valve dysfunction. We aimed to study Mexican patients with BAV to assess phenotypic expressions of BAV, and associations of valvulopathy and aortopathy and their predictors. A cross-sectional, retrospective study was designed. The patients were divided according to (1) normally or minimally dysfunctional BAV, (2) predominant aortic regurgitation (AR), and (3) predominant aortic stenosis (AS). A total of 189 patients were included with a high prevalence of males (68%). The overall median age was 42 (23 to 52) years. The distribution of fused BAV phenotypes was right-left fusion (77%), right noncoronary fusion (17%) and left noncoronary fusion (6%). AS-predominant group was the oldest with a high prevalence of hypertension, type 2 diabetes mellitus (T2DM), and raphe. In multivariable analysis T2DM (odds ratio [OR] 10.5 [95% confidence interval (CI) 2.1 to 52], p <0.01) and presence of raphe (OR 2.58 [95% CI 1.02 to 6.52], p = 0.04) were independently associated with AS. The AR-predominant group was composed mostly of males with significantly fewer cardiovascular risk factors. Male gender (OR 2.84 [95%CI 121 to 6.68], p = 0.01) and aortic dilatation (OR 3.58 [95% CI 1.73 to 7.39], p <0.01) were associated with AR-predominance in multivariable analysis. Aortic dilatation was associated with age (OR 1.03 [95% CI 1.008 to 1.05], p <0.01) and AR (OR 4.31 [95% CI 2.05 to 9.06], p <0.01). Independent factors associated with the root phenotype were male gender (OR 12.4 [95% CI 1.6 to 95], p <0.01) and AR (OR 5.25 [95% CI 2.18 to 12.6], p <0.01).In conclusion, in a mestizo population, the distribution of BAV-fused phenotypes was similar to European and North American populations, the presence of raphe and T2DM were independently associated with AS-predominance, and male gender and aortic dilatation were independently associated with AR-predominance.

Bioprosthesis in aortic valve replacement: long-term inflammatory response and functionality.

BACKGROUND: The evaluation of long-term inflammatory response and function in postoperative patients with aortic valve replacement (AVR) deserves special analysis because it is important to try to prevent reoperation and improve durability and functionality of the prostheses. It is our objective METHODS: In this study, we included a cohort of patients with aortic valve damage treated by AVR with mechanical prosthesis, bio prosthesis and we included a control group. RESULTS: We found that IL-4 and osteopontin levels were higher in patients with mechanical vs biological prostheses (p=0.01 and p=0.04, respectively), osteoprotegerin (OPG) levels were decreased (p=0.01), women had lower levels of ET-1 and IL-6, (p=0.02) (p=0.04), respectively. Patients older than 60 years had decreased levels of IL-1ß p<0.001) and a higher concentration of IL-4 p<0.05). IL-1ß, OPG and TNFα were higher in patients with less than 5 years of evolution vs more than 10 years (p=0.004, p=0.02 and p=0.03, respectively). Factors such as age, gender, prosthetic and elevated IL-1B and ET-1 levels are associated with valve dysfunction prosthetic. These results indicate that the inflammatory involvement present prior to valve replacement may be perpetuated by various factors in the long term. CONCLUSIONS: The findings provide us with the opportunity to effectively treat patients with AVR in the postoperative period, which could prolong the functionality of the bio prostheses. TRIAL REGISTRATION NUMBER: NCT04557345.

Attached right aortic valve leaflet causing ischemia and severe regurgitation: Successful repair with Ozaki technique.

INTRODUCTION: Coronary artery occlusion due to fusion of a leaflet to the sinotubular junction is a rare finding that we should consider in the differential diagnosis of young patients who have aortic regurgitation and angina. PATIENT AND METHOD: We present a young female with severe aortic regurgitation due to right coronary fusion who underwent mini-invasive aortic valve reconstruction. RESULTS: Postoperative evolution was satisfactory. The patient was discharged on the 5th postoperative day and after 3.5 years of follow-up he remains in functional class I, without anticoagulant treatment and with mild aortic regurgitation. COCNCLUSION: The Ozaki technique can be used in patients with aortic regurgitation due to single leaflet dysfunction.

Técnica minimalista para valvuloplastía aórtica percutánea / Minimally invasive balloon aortic valve valvuloplastyBackground

RESUMEN: ANTECEDENTES: La valvuloplastía aórtica es un procedimiento paliativo o como puente al reemplazo aórtico percutáneo o quirúrgico. Nuestro abordaje incluye una técnica minimalista y la utilización de balones de mayor tamaño que lo estándar. OBJETIVO: Evaluar los resultados clínicos inmediatos y alejados de pacientes tratados mediante esta técnica modificada. MÉTODOS: Se incluyó a todos los pacientes sometidos a balonplastía aórtica entre Julio del 2012 y Agosto del 2019 en nuestro centro. El procedimiento se realizó bajo sedación consciente mediante un único acceso femoral y sin instalación de un marcapasos transitorio. El éxito de la intervención se definió como caída de gradiente basal en 50% o más en ausencia de complicación mayor. RESULTADOS: Se realizaron un total de 52 procedimientos en 49 pacientes. La edad promedio fue 76 ± 9,9 años. Un tercio de los pacientes tenía una fracción de eyección del ventrículo izquierdo ≤35% y similar proporción tenía un perfil de riesgo STS score > 10 puntos. La duración total promedio fue de 31,1 + 10,0 min. Se utilizó un balón #28 en el 84.6% de los casos. El éxito del procedimiento se alcanzó en 94,2% de los casos. Ocurrieron 2 muertes intraoperatorias (3,9%), ambas en pacientes de muy alto riesgo y 2 (3,9%) complicaciones vasculares mayores. La sobreviva en el seguimiento alejado fue 32,7%. CONCLUSIÓN: La valvuloplastia aórtica percutánea con técnica modificada, utilizando balones de mayor tamaño que lo habitual, es una técnica segura que logra óptimos resultados hemodinámicos.

ABSTRACT: Aortic balloon valvuloplasty (ABV) is a palliative procedure or a bridge to percutaneous or surgical aortic valve replacement. Our group proposes a minimalist approach that reduces the use of resources and also stands out for using larger balloons. AIM: To assess the safety and the immediate results of patients undergoing aortic balloon valvuloplasty using a minimally invasive procedure. METHODS: All patients who underwent ballon aortic valvuloplasty (BAV) between July 2012 and Au- gust 2019 were included. The procedure was performed under conscious sedation using a single femoral access and without the installation of a temporary pacemaker. Success was defined as a 50% drop in the mean aortic gradient plus the absence of major complications. RESULTS: 52 procedures in 49 patients were performed; the average age was 76 ± 9,9 years. A third of patients included had a left ventricular ejection fraction ≤35% and a similar proportion had a high risk profile with an STS score> 10 points. A 28 mm balloon was used in 84.6% of cases. The procedure was successful in 94,2% of cases. There were 2 (3,85%) intraoperative deaths in very high-risk patients and 2 (3,85%) major vascular complications. The survival rate at late follow up was 32,7%. CONCLUSION: Aortic balloon valvuloplasty with a minimally invasive technique using larger than usual balloons is a safe technique that achieves optimal hemodynamic results.

Evaluation of Ventricular Remodeling and Prognosis in Patients with Aortic Stenosis Who Underwent Surgical or Percutaneous Transcatheter Aortic Valve Replacement.

INTRODUCTION: Aortic stenosis is the most common heart valve disease in the world, and patients that present with symptoms have a high mortality rate. Aortic valve replacement has the objective of promote left ventricular remodeling, reduce symptoms, and increase overall survival. The objective of this study is to evaluate reverse remodeling of the left ventricle in patients with severe and symptomatic aortic stenosis who underwent surgical or percutaneous transcatheter aortic valve replacement. METHODS: This is a longitudinal, prospective, non-concurrent, non-randomized unicentric study with patients who underwent aortic valve replacement. Echocardiogram was performed before and after replacement procedure to evaluate several remodeling indexes. RESULTS: Of 91 patients, 77 (84.6%) underwent surgical aortic valve replacement, and 14 (15.4%) underwent percutaneous transcatheter aortic valve replacement. Mean age was 68,96±11,98 years, and most patients were male. Remodeling evaluation revealed that patients who decreased left ventricular index mass (53% vs. 38.9%; P=0,019) and those who reduced the mass/volume ratio (30.4% vs. 68.9%; P<0,001) presented with positive left ventricular remodeling. No endpoint difference was found in those with positive remodeling. CONCLUSION: Regarding the left ventricular remodeling in patients with severe and symptomatic aortic valve stenosis who underwent percutaneous transcatheter or surgical valve replacement, there is a positive increment in remodeling, however it remains in concentric hypertrophic shape. Implication of these findings remains uncertain and to be studied in large dedicated trials with clinical endpoints.

Clinical Profile and 30-Day Outcomes of Patients with Bicuspid Aortic Valve Undergoing Aortic Valve and/or Aorta Surgery. / Perfil Clínico e Desfechos em 30 Dias de Pacientes Portadores de Valva Aórtica Bicúspide Submetidos à Cirurgia em Valva Aórtica e/ou Aorta.

BACKGROUND: The bicuspid aortic valve (BAV) affects 0.5 to 2% of the population and is associated with valve and aortic alterations. There is a lack of studies on the profile of these patients in the Brazilian population. OBJECTIVE: To describe the profile of patients with BAV undergoing valve and/or aortic surgery in a tertiary cardiology center, in addition to the outcomes related to the intervention. METHODS: Retrospective cohort including 195 patients (mean age 54±14 years, 73.8% male) diagnosed with BAV who underwent surgical approach (valvular and/or aorta) from 2014 to 2019. Clinical data, echocardiographic and tomographic studies were evaluated, as well as characteristics of the intervention and events in 30 days. A value of p<0.05 was considered statistically significant. RESULTS: We found a high prevalence of aortic aneurysm (56.5%), with a mean diameter of 46.9±10.2 mm. Major aortic regurgitation was found in 25.1% and major aortic stenosis in 54.9%. Isolated aortic valve surgery was performed in 48.2%, isolated aortic surgery in 6.7% and combined surgery in 45.1%. The 30-day mortality was 8.2%. In the multivariate analysis, the predictors of the combined outcome at 30 days (death, atrial fibrillation and reoperation) were age (OR 1.044, 95% CI 1.009-1.081, p=0.014) and left ventricular mass index (OR 1.009, 95% CI 1.000-1.018, p=0.044). CONCLUSION: Patients with BAV approached in our service have a higher incidence of aortopathy, with the additional need to evaluate the aorta with computed tomography or magnetic resonance imaging.

FUNDAMENTO: A válvula aórtica bicúspide (VAB) atinge de 0,5 a 2% da população e está associada a alterações valvares e de aorta. Há carência de estudos sobre o perfil desses pacientes na população brasileira. OBJETIVO: Descrever o perfil de pacientes com VAB submetidos à cirurgia valvar e/ou de aorta em um centro cardiológico terciário, assim como os desfechos relacionados à intervenção. MÉTODOS: Coorte retrospectiva incluindo 195 pacientes (idade média 54±14 anos, 73,8% do sexo masculino) com diagnóstico de VAB submetidos à abordagem cirúrgica (valvar e/ou de aorta) no período de 2014 a 2019. Foram avaliados dados clínicos, ecocardiográficos e tomográficos, além das características da intervenção e eventos em 30 dias. O valor de p<0,05 foi considerado estatisticamente significante. RESULTADOS: Encontramos alta prevalência de aneurisma de aorta (56,5%), com diâmetro médio de 46,9±10,2 mm. Insuficiência aórtica importante foi encontrada em 25,1% e estenose aórtica importante em 54,9%. Cirurgia isolada em valva aórtica foi realizada em 48,2%, cirurgia isolada de aorta em 6,7% e cirurgia combinada em 45,1%. A mortalidade em 30 dias foi de 8,2%. Na análise multivariada, os fatores preditores de desfecho combinado em 30 dias (morte, fibrilação atrial e reoperação) foram idade (OR 1,044, IC 95% 1,009-1,081, p=0,014) e o índice de massa do ventrículo esquerdo (OR 1,009, IC 95% 1,000-1,018, p=0,044). CONCLUSÃO: Pacientes com VAB abordados no nosso serviço apresentam uma maior incidência de aortopatia, com a necessidade adicional de avaliação da aorta com tomografia computadorizada ou ressonância magnética.
