Evaluation of the 2023 Duke-ISCVID and 2023 Duke-ESC Clinical Criteria for the Diagnosis of Infective Endocarditis in a Multicenter Cohort of Patients With Staphylococcus aureus Bacteremia. Clin Infect Dis 2024; 78:655-662. [PMID: 38168726 PMCID: PMC10954331 DOI: 10.1093/cid/ciae003] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 12/14/2023] [Accepted: 12/28/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND The Duke criteria for infective endocarditis (IE) diagnosis underwent revisions in 2023 by the European Society of Cardiology (ESC) and the International Society for Cardiovascular Infectious Diseases (ISCVID). This study aims to assess the diagnostic accuracy of these criteria, focusing on patients with Staphylococcus aureus bacteremia (SAB). METHODS This Swiss multicenter study conducted between 2014 and 2023 pooled data from three cohorts. It evaluated the performance of each iteration of the Duke criteria by assessing the degree of concordance between definite S. aureus IE (SAIE) and the diagnoses made by the Endocarditis Team (2018-23) or IE expert clinicians (2014-17). RESULTS Among 1344 SAB episodes analyzed, 486 (36%) were identified as cases of SAIE. The 2023 Duke-ISCVID and 2023 Duke-ESC criteria demonstrated improved sensitivity for SAIE diagnosis (81% and 82%, respectively) compared to the 2015 Duke-ESC criteria (75%). However, the new criteria exhibited reduced specificity for SAIE (96% for both) compared to the 2015 criteria (99%). Spondylodiscitis was more prevalent among patients with SAIE compared to those with SAB alone (10% vs 7%, P = .026). However, when patients meeting the minor 2015 Duke-ESC vascular criterion were excluded, the incidence of spondylodiscitis was similar between SAIE and SAB patients (6% vs 5%, P = .461). CONCLUSIONS The 2023 Duke-ISCVID and 2023 Duke-ESC clinical criteria show improved sensitivity for SAIE diagnosis compared to 2015 Duke-ESC criteria. However, this increase in sensitivity comes at the expense of reduced specificity. Future research should aim at evaluating the impact of each component introduced within these criteria.

The racial disparity among post transcatheter aortic valve replacement outcomes: A meta-analysis. IJC HEART & VASCULATURE 2023; 44:101170. [PMID: 36660201 PMCID: PMC9843207 DOI: 10.1016/j.ijcha.2023.101170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Revised: 12/17/2022] [Accepted: 01/01/2023] [Indexed: 01/13/2023]
Abstract
Background Racial disparities have been well described in cardiovascular disease. However, the impact of race on the outcomes post - Transcatheter aortic valve replacement (TAVR) remains unknown. Objective We aim to evaluate the disparity among the race (black and white) post - TAVR. Methods We systematically searched all electronic databases from inception until September 26, 2022. The primary outcome was in-hospital all-cause mortality, and secondary outcomes was myocardial infarction (MI), acute kidney injury (AKI), permanent pacemaker implantation (PPI) or ICD, stroke, vascular complications, and major bleeding. Results A total of three studies with 1,02,009 patients were included in the final analysis. The mean age of patients with white and black patients was 82.65 and 80.45 years, respectively. The likelihood of in-hospital all-cause mortality (OR, 1.01(95 %CI: 0.86-1.19), P = 0.93), stroke (OR, 0.83(95 %CI:0.61-1.13), P = 0.23, I2 = 46.57 %], major bleeding [OR, 1.05(95 %CI:0.92-1.20), P = 0.46), and vascular complications [OR, 0.92(95 %CI:0.81-1.06), P = 0.26), was comparable between white and black patients. However, patients with white race have lower odds of MI (OR, 0.65(95 %CI:0.50-0.84), P < 0.001), and AKI (OR, 0.84(95 %CI:0.74-0.95), P = 0.01) and higher odds of PPI or ICD (OR, 1.16(95 %CI: 1.06-1.27), P < 0.001, I2 = 0 %) compared with black race patients. Conclusion Our findings suggest disparity post - TAVR outcomes existed, and black patients are at higher risk of MI and AKI than white patients.Key Clinical Message:•What is already known on this topic: Disparity has been witnessed among patients with cardiovascular disease. However, no studies have drawn a significant association among post-TAVR patients' outcomes•What this study adds: Among patients who underwent TAVR, there is a difference in the adverse outcomes between black and white race patients. White patients have a lower risk of post-procedure MI and AKI compared with Black patients.•How this study might affect research, practice, or policy: These disparities need to be addressed, and proper guidelines need to be made along with engaging patients with better medical infrastructure and treatment options..

Abstract
In the past few decades, the accelerated improvement in technology has allowed the development of new and effective coronary and structural heart disease interventions. There has been inequitable patient access to these advanced therapies and significant disparities have affected patients from low socioeconomic positions. In the US, these disparities mostly affect women, black and hispanic communities who are overrepresented in low socioeconomic. Other adverse social determinants of health influenced by structural racism have also contributed to these disparities. In this article, we review the literature on disparities in access and use of coronary and structural interventions; delineate the possible reasons underlying these disparities; and highlight potential solutions at the government, healthcare system, community and individual levels.

Abstract
Background Racial and ethnic inequities exist in surgical aortic valve replacement for aortic stenosis (AS), and early studies have suggested similar inequities in transcatheter aortic valve replacement. Methods and Results We performed a retrospective analysis of the Maryland Health Services Cost Review Commission inpatient data set from 2016 to 2018. Black patients had half the incidence of any inpatient AS diagnosis compared with White patients (incidence rate ratio [IRR], 0.50; 95% CI, 0.48–0.52; P<0.001) and Hispanic patients had one fourth the incidence compared with White patients (IRR, 0.25; 95% CI, 0.22–0.29; P<0.001). Conversely, the incidence of any inpatient mitral regurgitation diagnosis did not differ between White and Black patients (IRR, 1.00; 95% CI, 0.97–1.03; P=0.97) but was significantly lower in Hispanic compared with White patients (IRR, 0.36; 95% CI, 0.33–0.40; P<0.001). After multivariable adjustment, Black race was associated with a lower incidence of surgical aortic valve replacement (IRR, 0.67; 95% CI, 0.55–0.82 P<0.001 relative to White race) and transcatheter aortic valve replacement (IRR, 0.77; 95% CI, 0.65–0.90; P=0.002) among those with any inpatient diagnosis of AS. Hispanic patients had a similar rate of surgical aortic valve replacement and transcatheter aortic valve replacement compared with White patients. Conclusions Hospitalization with any diagnosis of AS is less common in Black and Hispanic patients than in White patients. In hospitalized patients with AS, Black race is associated with a lower incidence of both surgical aortic valve replacement and transcatheter aortic valve replacement compared with White patients, whereas Hispanic patients have a similar incidence of both. The reasons for these inequities are likely multifactorial.

Abstract
Cardiovascular disease (CVD) remains the leading cause of death in the United States. However, percutaneous interventional cardiovascular therapies are often underutilized in Blacks, Hispanics, and women and may contribute to excess morbidity and mortality in these vulnerable populations. The Society for Cardiovascular Angiography and Interventions (SCAI) is committed to reducing racial, ethnic, and sex-based treatment disparities in interventional cardiology patients. Accordingly, each of the SCAI Clinical Interest Councils (coronary, peripheral, structural, and congenital heart disease [CHD]) participated in the development of this whitepaper addressing disparities in diagnosis, treatment, and outcomes in underserved populations. The councils were charged with summarizing the available data on prevalence, treatment, and outcomes and elucidating potential reasons for any disparities. Given the huge changes in racial and ethnic composition by age in the United States (Figure 1), it was difficult to determine disparities in rates of diagnosis and we expected to find some racial differences in prevalence of disease. For example, since the average age of patients undergoing transcatheter aortic valve replacement (TAVR) is 80 years, one may expect 80% of TAVR patients to be non-Hispanic White. Conversely, only 50% of congenital heart interventions would be expected to be performed in non-Hispanic Whites. Finally, we identified opportunities for SCAI to advance clinical care and equity for our patients, regardless of sex, ethnicity, or race.

AMERICAN JOURNAL OF CARDIOVASCULAR DISEASE 2021; 11:203-211.

Abstract
OBJECTIVE In the United States, racial minorities are underrepresented among patients receiving transcatheter aortic valve replacement (TAVR) and data regarding their outcomes is limited. Global longitudinal strain (GLS) is a measure left ventricular function and has independently predicted outcomes after TAVR. The aim of this study is to assess changes in GLS after TAVR according to race and factors predicting these changes. METHODS Electronic medical records of patients undergoing TAVR at the University of Illinois, Chicago and Jesse Brown Veteran's Administration Medical Center (Chicago, Illinois) from January 2017-February 2020 were reviewed retrospectively. The most recent transthoracic echocardiogram (TTE) prior to TAVR and the TTE 1-month post-procedure were used to determine GLS. Patients were included if both a pre- and post-procedure study were present and TTE images were of sufficient quality to process strain imaging. RESULTS A total of 103 patients (average age 76 ± 12 years, 80% male, 42% white) were included. At 1-month post-TAVR, GLS improved for all races: white (-2.7 ± 3.5%, P<0.001), African-American (-2.8 ± 3.3%, P<0.001), and Hispanic (-2.0 ± 2.1%, P<0.001). There were no differences in the degree of improvement among races (P=0.62). Baseline GLS was negatively correlated with changes in GLS overall (r=-0.44, P<0.001). Baseline aortic valve area (cm2) was positively correlated with changes in GLS (r=0.2, P=0.036). CONCLUSIONS This study demonstrated that GLS improved after TAVR independent of race with similar degrees of change across races. Baseline GLS and aortic valve area predicted strain improvement after TAVR, which suggests that those with more impaired LV function may benefit most from the procedure.

Abstract
The constituents of normal cardiac valves as well as those involved by active and/or chronic processes have been detailed previously, however minor attention has been provided toward mature adipocytes within valves and correlation with other histologic, clinical, and echocardiographic data. The literature also contains a paucity of investigations examining the presence of a particular form of degenerative change of mature adipocytes termed membranous fat necrosis. We retrospectively reviewed the histologic findings of 1042 native cardiac valves which included identification of the presence of adipocytes and membranous fat necrosis within them, as well as correlation with other histopathologic features, and clinical and echocardiographic findings. Notable observations included that membranous fat necrosis was only present in valves with adipocytes, adipocytes and membranous fat necrosis were seen in older patients, and that Caucasians made up a greater proportion of patients while African Americans made up a lower proportion of patients when valves were found with adipocytes and membranous fat necrosis. Aortic valves contained adipocytes and membranous fat necrosis at a greater rate than compared to other valves, and aortic valves with adipocytes and membranous fat necrosis were more commonly tricuspid (as opposed to bicuspid) and with larger aortic valve area and lower peak and mean gradients. Further investigation is required to determine potential physiologic and/or pathologic consequence of their presence.

Abstract
Aortic stenosis (AS) is the third most common type of cardiovascular disease after hypertension and coronary artery disease, and it carries a high mortality rate when left untreated. Risk factors include male sex, hypertension, tobacco use, advanced age, elevated LDL cholesterol, and coronary atherosclerosis. Definitive treatment for AS includes valve repair, either percutaneously or surgically; however, in aging populations corrective surgery carries increased risk. While research suggests that patients of some non-White ethnic groups, including African-Americans, are less likely than their Caucasian counterparts to have AS, these minority patients may experience may experience differences in the way they receive and accept care. This paper seeks to explicate the mechanisms of racial disparities among the African-Americans affected by aortic stenosis as they pertain to healthcare utilization, referral for valve replacement, acceptance of therapy, and overall treatment outcomes.

Abstract
BACKGROUND Statins are thought to have little effect on the progression of aortic stenosis, but the data on their role in patients with aortic valve sclerosis (AVS) are limited and inconsistent. METHODS We retrospectively analyzed 541 consecutive patients (214 men, age: 70 ± 11 years) with AVS. Each patient underwent two or more electrocardiography examinations at least 6 months apart at Kangwon National University Hospital from August 2010 to August 2015. AVS is defined as irregular thickening of the leaflets, focal increases in echogenicity and minimal elevation of the peak aortic valve velocity (> 1.5 and < 2 m/s). The progression rate of AVS was expressed as the increase in peak velocity per year (m/s/yr). RESULTS The mean follow-up duration was 24.9 ± 13.3 months in the statin-treated group and 24.1 ± 12.4 months in the non-statin-treated group (p = 0.460). There were no differences between the statin-treated and non-statin-treated groups in mean age, gender or smoking status. Relative to the non-statin-treated group, a higher number of patients in the statin-treated group had hypertension, diabetes, ischemic heart disease, and stroke. The progression rate of AVS did not differ between the statin-treated and non-statin-treated groups (0.012 ± 0.340 m/s/yr vs. 0.014 ± 0.245 m/s/yr, p = 0.956). Multivariate analysis showed initial peak aortic jet velocity was significantly associated with AVS progression (β = 0.153, p = 0.009). CONCLUSIONS Our study demonstrated that statins had no effect on the progression of AVS. However, well-designed studies are needed to define the prognosis and management of AVS.

[PMID: 29506780 DOI: 10.1016/j.mayocp.2017.11.026] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Revised: 10/28/2017] [Accepted: 11/09/2017] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To assess the effect of race on the incidence of aortic stenosis (AS) and utilization and outcomes of aortic valve replacement (AVR). PATIENTS AND METHODS Patients older than 60 years hospitalized with a primary diagnosis of AS and those who underwent AVR between 2003 and 2014 were included. Adjusted and unadjusted incidence of AS-related hospitalizations, utilization rates of AVR, in-hospital morbidity and mortality, and resource utilization was compared between whites and African Americans (AAs). RESULTS Between January 1, 2003, and December 31, 2014, the incidence of AS-related admissions increased from 13 (95% CI, 12.8-13.2) to 26 (95% CI, 25.7-26.4) cases per 100,000 patient-years in whites and from 3 (95% CI, 3.5-3.8) to 9.5 (95% CI, 9.4-9.8) cases per 100,000 patient-years in AAs (P<.001). The incidence density ratio decreased from 4.3 (95% CI, 2.27-6.6) in 2003 to 2.7 (95% CI, 1.1-3.8) in 2014. The ratio of AVR to AS-related admissions was 11.3% in whites and 6.7% in AAs (P<.001). Crude in-hospital mortality after AVR was higher in AAs (6.4% vs 4.7%; P<.001). However, after propensity score matching, in-hospital morality after isolated AVR was not significantly different between AAs and whites (4.7% vs 3.7%; P=.12). African Americans also had longer hospitalizations (12±12 days vs 10±9 days; P<.001), higher rates of nonhome discharge (32.1% vs 27.2%; P=.004), and higher cost of hospitalization ($55,631±$37,773 vs $52,521±$38,040; P<.001). CONCLUSIONS African Americans undergo AVR less than whites. The underlying etiology of this disparity is multifactorial, but may be related to a lower incidence of AS in AAs. Aortic valve replacement is associated with similar risk-adjusted in-hospital mortality but higher cost and longer hospitalizations in AAs than in whites.

A transcriptome-wide association study identifies PALMD as a susceptibility gene for calcific aortic valve stenosis. Nat Commun 2018; 9:988. [PMID: 29511167 PMCID: PMC5840407 DOI: 10.1038/s41467-018-03260-6] [Citation(s) in RCA: 75] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Accepted: 01/31/2018] [Indexed: 12/21/2022] Open
Abstract
Calcific aortic valve stenosis (CAVS) is a common and life-threatening heart disease and the current treatment options cannot stop or delay its progression. A GWAS on 1009 cases and 1017 ethnically matched controls was combined with a large-scale eQTL mapping study of human aortic valve tissues (n = 233) to identify susceptibility genes for CAVS. Replication was performed in the UK Biobank, including 1391 cases and 352,195 controls. A transcriptome-wide association study (TWAS) reveals PALMD (palmdelphin) as significantly associated with CAVS. The CAVS risk alleles and increasing disease severity are both associated with decreased mRNA expression levels of PALMD in valve tissues. The top variant identified shows a similar effect and strong association with CAVS (P = 1.53 × 10−10) in UK Biobank. The identification of PALMD as a susceptibility gene for CAVS provides insights into the genetic nature of this disease, opens avenues to investigate its etiology and to develop much-needed therapeutic options. Progressive remodeling and calcification of the aortic valve leads to calcific aortic valve stenosis (CAVS) and, ultimately, heart failure. In a combined GWAS and TWAS approach, Thériault et al. identify PALMD as a candidate causal gene for CAVS, which is further supported by Mendelian randomization.

Abstract
Background Valvular heart diseases (VHD) is very common in clinical practice and has became the subject of growing attention in the field of cardiovascular medicine. Our aim was to assess the prevalence and correlates of VHD in the general population in Xinjiang, China. Methods Using a 4-stage stratified cluster random sampling method, a total of 14618 participants were recruited in the Cardiovascular Risk Survey (CRS) study. The participants’ personal information, medical history were assessed by questionnaire. VHD was diagnosed by transthoracic echocardiography. We carried out the statistical analysis utilizing SPSS Statistics version 19.0. Results In the total study group, VHD was observed in 1397 (9.65%) individuals. The prevalence rates of VHD in Han, Uygur and Kazak group are 13.51%, 2.71% and 12.29% respectively. The prevalence rates of VHD increased strikingly with age (all P < 0.001). The results of multinomial regression analysis indicated that VHD were related to age in Han group, to age smoking and hypertension in Uygur group, to age and hypertension in Kazak group. Conclusion Our research provides a unique prevalence rate of VHD in Xinjiang natural population. The result suggests that VHD are notably common in this population (9.65%) and increase with age. There exists significant difference of prevalence rate between ethnics. The main risk factors of VHD are age, hypertension and smoking. Valvular heart diseases should be regarded as a serious and growing public-health problem.

Abstract
INTRODUCTION Aortic valve calcification (AVC) is the most common cause of aortic stenosis. The aim of the study was to assess the prevalence of aortic valve, coronary artery and aortic calcifications and to evaluate the correlation between calcification of the aortic valve, coronary arteries and aorta. MATERIAL AND METHODS The study included 499 patients aged 60 years and over who underwent coronary computed tomography because of chest pain. Beside coronary artery calcium score (CAC), we evaluated AVC and ascending aorta calcifications (AAC). RESULTS Aortic valve calcification was found in 144 subjects (28.9% of the whole study population). Prevalence of CAC and AAC was higher than AVC and amounted to 73.8% and 54.0%. Prevalence of AVC, CAC and AAC was significantly lower in the group of patients ≤ 70 years than in the group of patients > 70 years of age (p = 0.0002, p < 0.0001, p < 0.0001). Aortic valve calcification was more often observed in men than women (34.7% vs. 25.4%, p = 0.02). Degree of aortic valve calcification was also significantly higher among men than women (median score 4 vs. 0, p = 0.01). Similar observations were true for CAC and AAC, where both prevalence and degree of calcification was higher among men than women. In the whole study population no correlation was noted between AVC and CAC or AAC (p = 0.34, p = 0.85). There was a significant correlation between AAC and CAC (p < 0.0001). CONCLUSIONS Despite some similarities in pathological mechanism and risk factors, a degenerative defect of the aortic valve could be independent of atheromatous lesions in the coronary arteries and aorta.

Abstract
BACKGROUND In an era of expanded treatment options for severe aortic stenosis, it is important to understand risk factors for the condition. It has been suggested that severe aortic stenosis is less common in African Americans, but there are limited data from large studies. METHODS AND RESULTS The Synthetic Derivative at Vanderbilt University Medical Center, a database of over 2.1 million de-identified patient records, was used to identify individuals who had undergone echocardiography. The association of race with severe aortic stenosis was examined using multivariable logistic regression analyses adjusting for conventional risk factors. Of the 272 429 eligible patients (mean age 45 years, 44% male) with echocardiography, 14% were African American and 82% were Caucasian. Severe aortic stenosis was identified in 106 (0.29%) African-American patients and 2030 (0.91%) Caucasian patients (crude OR 0.32, 95% CI [0.26, 0.38]). This difference persisted in multivariable-adjusted analyses (OR 0.41 [0.33, 0.50], P<0.0001). African-American individuals were also less likely to have severe aortic stenosis due to degenerative calcific disease (adjusted OR 0.47 [0.36, 0.61]) or congenitally bicuspid valve (crude OR 0.13 [0.02, 0.80], adjusted OR dependent on age). Referral bias against those with severe valvular disease was assessed by comparing the prevalence of severe mitral regurgitation in Caucasians and African Americans and no difference was found. CONCLUSIONS These findings suggest that African Americans are at significantly lower risk of developing severe aortic stenosis than Caucasians.

Abstract
OBJECTIVES The aim of this study was to comprehensively review the epidemiology of aortic sclerosis (ASc) and its association with cardiovascular events. BACKGROUND ASc, which is defined as thickening or calcification of the aortic valve without significant obstruction of blood flow, is a common finding on cardiac imaging. METHODS We searched MEDLINE and EMBASE from inception to April 2013 for studies describing the epidemiology of ASc and performed a meta-analysis of the risk of adverse events using a random effects model. RESULTS Twenty-two studies were identified from the systematic review. The prevalence of ASc increased in proportion to the average age of study participants, ranging from 9% in a study in which the mean age was 54 years to 42% in a study in which the mean age was 81 years. In total, 1.8% to 1.9% of participants with ASc had progression to clinical aortic stenosis per year. There was a 68% increased risk of coronary events in subjects with ASc (hazard ratio [HR]: 1.68; 95% confidence interval [CI]: 1.31 to 2.15), a 27% increased risk of stroke (HR: 1.27; 95% CI: 1.01 to 1.60), a 69% increased risk of cardiovascular mortality (HR: 1.69; 95% CI: 1.32 to 2.15), and a 36% increased risk of all-cause mortality (HR: 1.36; 95% CI: 1.17 to 1.59). CONCLUSIONS ASc is a common finding that is more prevalent with older age. Despite low rates of progression to ASc, there is an independent increase in morbidity and mortality associated with the condition.

Abstract
Over the past 5 years, the advent of echocardiographic screening for rheumatic heart disease (RHD) has revealed a higher RHD burden than previously thought. In light of this global experience, the development of new international echocardiographic guidelines that address the full spectrum of the rheumatic disease process is opportune. Systematic differences in the reporting of and diagnostic approach to RHD exist, reflecting differences in local experience and disease patterns. The World Heart Federation echocardiographic criteria for RHD have, therefore, been developed and are formulated on the basis of the best available evidence. Three categories are defined on the basis of assessment by 2D, continuous-wave, and color-Doppler echocardiography: 'definite RHD', 'borderline RHD', and 'normal'. Four subcategories of 'definite RHD' and three subcategories of 'borderline RHD' exist, to reflect the various disease patterns. The morphological features of RHD and the criteria for pathological mitral and aortic regurgitation are also defined. The criteria are modified for those aged over 20 years on the basis of the available evidence. The standardized criteria aim to permit rapid and consistent identification of individuals with RHD without a clear history of acute rheumatic fever and hence allow enrollment into secondary prophylaxis programs. However, important unanswered questions remain about the importance of subclinical disease (borderline or definite RHD on echocardiography without a clinical pathological murmur), and about the practicalities of implementing screening programs. These standardized criteria will help enable new studies to be designed to evaluate the role of echocardiographic screening in RHD control.

Abstract
Background Although there were studies about ethnic differences in aortic valve thickness and calcification that they may play a role in aortic valvular stenosis (AVS) progression, few studies about the progression rate of AVS in Asian population have been reported. The purpose of this study was to evaluate the progression rate of AVS in Korean patients. Methods We retrospectively analyzed 325 patients (181 men, age: 67 ± 13 years) with AVS who had 2 or more echocardiograms at least 6 months apart from 2003 to 2008. The patients with other significant valvular diseases or history of cardiac surgery were excluded. The progression rate of AVS was expressed in terms of increase in maximum aortic jet velocity per year (meter/second/year). Results Baseline AVS was mild in 207 (64%), moderate in 81 (25%), and severe in 37 (11%). There were no significant differences among the three groups in terms of age, gender, hypertension, smoking, and hypercholesterolemia. The mean progression rate was 0.12 ± 0.23 m/s/yr and more rapid in severe AVS (0.28 ± 0.36 m/s/yr) when compared to moderate (0.14 ± 0.26 m/s/yr) and mild AVS (0.09 ± 0.18 m/s/yr) (p < 0.001). The progression rate in bicuspid AVS was significantly higher than other AVS (0.23 ± 0.35 vs. 0.11 ± 0.20 m/s/yr, p = 0.002). By multivariate analysis, initial maximum aortic jet velocity (Beta = 0.175, p = 0.003), bicuspid aortic valve (Beta = 0.127, p = 0.029), and E velocity (Beta = -0.134, p = 0.018) were significantly associated with AVS progression. Conclusion The progression rate of AVS in Korean patients is slower than that reported in Western population. Therefore, ethnic difference should be considered for the follow-up of the patients with AVS.
