ABSTRACT
BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an increasingly used but relatively expensive procedure with substantial associated readmission rates. It is unknown how cost-constrictive payment reform measures, such as Maryland's All Payer Model, impact TAVR utilization given its relative expense. This study investigated the impact of Maryland's All Payer Model on TAVR utilization and readmissions among Maryland Medicare beneficiaries. METHODS: This was a quasi-experimental investigation of Maryland Medicare patients undergoing TAVR between 2012 and 2018. New Jersey data were used for comparison. Longitudinal interrupted time series analyses were used to study TAVR utilization and difference-in-differences analyses were used to investigate post-TAVR readmissions. RESULTS: During the first year of payment reform (2014), TAVR utilization among Maryland Medicare beneficiaries dropped by 8% (95% confidence interval [CI]: -9.2% to -7.1%; p < 0.001), with no concomitant change in TAVR utilization in New Jersey (0.2%, 95% CI: 0%-1%, p = 0.09). Longitudinally, however, the All Payer Model did not impact TAVR utilization in Maryland compared to New Jersey. Difference-in-differences analyses demonstrated that implementation of the All Payer Model was not associated with significantly greater declines in 30-day post-TAVR readmissions in Maryland versus New Jersey (-2.1%; 95% CI: -5.2% to 0.9%; p =0.1). CONCLUSIONS: Maryland's All Payer Model resulted in an immediate decline in TAVR utilization, likely a result of hospitals adjusting to global budgeting. However, beyond this transition period, this cost-constrictive reform measure did not limit Maryland TAVR utilization. In addition, the All Payer Model did not reduce post-TAVR 30-day readmissions. These findings may help inform expansion of globally budgeted healthcare payment structures.

BACKGROUND: Knowledge gaps remain in the epidemiology and clinical implications of myocardial injury in coronavirus disease 2019 (COVID-19). We aimed to determine the prevalence and outcomes of myocardial injury in severe COVID-19 compared with acute respiratory distress syndrome (ARDS) unrelated to COVID-19. METHODS: We included intubated patients with COVID-19 from 5 hospitals between March 15 and June 11, 2020, with troponin levels assessed. We compared them with patients from a cohort study of myocardial injury in ARDS and performed survival analysis with primary outcome of in-hospital death associated with myocardial injury. In addition, we performed linear regression to identify clinical factors associated with myocardial injury in COVID-19. RESULTS: Of 243 intubated patients with COVID-19, 51% had troponin levels above the upper limit of normal. Chronic kidney disease, lactate, ferritin, and fibrinogen were associated with myocardial injury. Mortality was 22.7% among patients with COVID-19 with troponin under the upper limit of normal and 61.5% for those with troponin levels >10 times the upper limit of normal (P<0.001). The association of myocardial injury with mortality was not statistically significant after adjusting for age, sex, and multisystem organ dysfunction. Compared with patients with ARDS without COVID-19, patients with COVID-19 were older and had higher creatinine levels and less favorable vital signs. After adjustment, COVID-19-related ARDS was associated with lower odds of myocardial injury compared with non-COVID-19-related ARDS (odds ratio, 0.55 [95% CI, 0.36-0.84]; P=0.005). CONCLUSIONS: Myocardial injury in severe COVID-19 is a function of baseline comorbidities, advanced age, and multisystem organ dysfunction, similar to traditional ARDS. The adverse prognosis of myocardial injury in COVID-19 relates largely to multisystem organ involvement and critical illness.

OBJECTIVES: We aimed to evaluate the risk of procedural complications after TAVR using secondary radial access (RA) versus femoral access (FA) through a systematic review and meta-analysis of the published literature. BACKGROUND: Transcatheter aortic valve replacement (TAVR) entails both large-bore arterial access for device delivery and secondary arterial access for hemodynamic and imaging assessments. It is unknown whether RA versus FA for this secondary access reduces the risk of procedural complications. METHODS: We searched PubMed, Embase, the Cochrane Library, and Web of Science for observational studies comparing TAVR procedural complications in RA versus FA. Event rates were compared via weighted summary odds ratios using the Mantel-Haenszel method. RESULTS: Six manuscripts encompassing 6132 patients were included. Meta-analysis showed that RA reduced the risk of major vascular complications (OR 0.58, 95% CI 0.43-0.77, p < 0.001, I2 0%) and major/life-threatening bleeding (OR 0.46, 95% CI 0.36-0.59, p < 0.001, I2 0%) as compared to FA for secondary TAVR access. We also observed a reduction 30-day mortality (OR 0.55, 95% CI 0.38-0.79, p = 0.001, I2 0%), acute kidney injury (OR 0.45, 95% CI 0.34-0.60, p < 0.001, I2 0%), and stroke and transient ischemic attack (OR 0.43, 95% CI 0.27-0.67, p < 0.001, I2 0%). CONCLUSIONS: RA reduced the risk of major vascular and bleeding complications when compared to FA for secondary access in TAVR. RA is associated with reduced risk of other adverse outcomes including mortality, but these associations may be related to selection bias and confounding given the observational study designs.

AIMS: Physical frailty is a commonly encountered geriatric syndrome among older adults without coronary heart disease (CHD). The impact of frailty on the incidence of long-term cardiovascular outcomes is not known.We aimed to evaluate the long-term association of frailty, measured by the Fried frailty phenotype, with all-cause-mortality and MACE among older adults without a history of CHD at baseline in the National Health and Aging Trends Study. METHODS AND RESULTS: We used the National Health and Aging Trends Study, a prospective cohort study linked to a Medicare sample. Participants with a prior history of CHD were excluded. Frailty was measured during the baseline visit using the Fried physical frailty phenotype. Cardiovascular outcomes were assessed during a 6-year follow-up.Of the 4656 study participants, 3259 (70%) had no history of CHD 1 year prior to their baseline visit. Compared to those without frailty, subjects with frailty were older (mean age 82.1 vs. 75.1 years, P < 0.001), more likely to be female (68.3% vs. 54.9%, P < 0.001), and belong to an ethnic minority. The prevalence of hypertension, falls, disability, anxiety/depression, and multimorbidity was much higher in the frail and pre-frail than the non-frail participants. In a Cox time-to-event multivariable model and during 6-year follow-up, the incidences of death and of each individual cardiovascular outcomes were all significantly higher in the frail than in the non-frail patients including major adverse cardiovascular event (MACE) [hazard ratio (HR) 1.77, 95% confidence interval (CI) 1.53, 2.06], death (HR 2.70, 95% CI 2.16, 3.38), acute myocardial infarction (HR 1.95, 95% CI 1.31, 2.90), stroke (HR 1.71, 95% CI 1.34, 2.17), peripheral vascular disease (HR 1.80, 95% CI 1.44, 2.27), and coronary artery disease (HR 1.35, 95% CI 1.11, 1.65). CONCLUSION: In patients without CHD, frailty is a risk factor for the development of MACEs. Efforts to identify frailty in patients without CHD and interventions to limit or reverse frailty status are needed and, if successful, may limit subsequent adverse cardiovascular events.

BACKGROUND: Skeletal muscle wasting, or sarcopenia, affects a significant proportion of patients undergoing transcatheter aortic valve replacement (TAVR). However, its influence on post-TAVR recovery and 1-year health-related quality of life (HR-QOL) remains unknown. We examined the relationship between skeletal muscle index (SMI), post-TAVR length of hospital stay (LOS), and 1-year QOL. METHODS: The study sample consisted of 300 consecutive patients undergoing TAVR from 2012 to 2018 who had pre-TAVR computed tomographic scans suitable for analysis of body composition. Skeletal muscle mass was quantified as cm2 of skeletal mass per m2 of body surface area from the cross-sectional computed tomographic image at the third lumbar vertebra. Sarcopenia was defined using established sex-specific cutoffs (women: SMI <â¯39â¯cm2/m2; men: < 55â¯cm2/m2). Multivariable linear regression analysis was used to determine the relationship between SMI, LOS, and HR-QOL using the Kansas City Cardiomyopathy Questionnaire. RESULTS: Sarcopenia was present in most (59%) patients and associated with older age (82 vs 76â¯years; Pâ¯<â¯.001) and lower body mass index (27 vs 33â¯kg/m2; Pâ¯<â¯.001). There were no other differences in baseline clinical or echocardiographic characteristics among the 4 quartiles of SMI. SMI was positively correlated with LOS and 1-year QOL. After adjusting for age, gender, race, and body mass index, SMI remained a significant predictor of both LOS (Pâ¯=â¯.01) and 1-year QOL (Pâ¯=â¯.012). For every 10â¯cm2/m2 higher SMI, there was an 8-point increase in Kansas City Cardiomyopathy Questionnaire score, a difference that is clinically meaningful. CONCLUSIONS: Sarcopenia is prevalent in TAVR patients. Higher SMI is associated with shorter LOS and better 1-year HR-QOL. To achieve optimal TAVR benefits, further study into how body composition influences post-TAVR recovery and durable improvement in QOL is warranted.

OBJECTIVES: The Multi-center Prospective Study to Evaluate Outcomes of Moderate to Severely Calcified Coronary Lesions (MACE-Trial) was designed to provide further insight on the impact of calcification on procedural and long-term percutaneous coronary intervention outcomes. BACKGROUND: Prior studies evaluating the impact of lesion calcification on percutaneous coronary intervention outcomes are limited by: retrospective nature, pooled data from multiple studies, or lack of specificity around calcification with only operator assessment and without core lab evaluation. METHODS: The MACE-Trial was a prospective, multicenter, observational clinical study that enrolled 350 subjects at 33 sites from September 2013 to September 2015. Core lab assessed subject stratification by lesion calcification (none/mild [N = 133], moderate [N = 99], and severe [N = 114]). Endpoints were lesion success, procedural success, and 1-year major adverse cardiac events (MACEs). RESULTS: Presence of severe calcification had significant impact on lesion success ([83.3%] versus none/mild calcification [94.7%, P = 0.006]) and procedural success ([86.8%] versus moderate [95.0%, P = 0.028], and none/mild [97.7%, P = 0.001]). 1-year MACE rates were associated with presence of calcification in subjects with none/mild (4.7%), moderate (8.7%), and severe (24.4%) (P < 0.001) calcification; however, no difference was noted between none/mild and moderate (P = 0.237). The risk adjusted multivariable model identified severe calcification and decreasing eGFR as predictors of 30-day and 1-year MACE. CONCLUSIONS: In this prospective study, patients with severe calcification had significantly worse outcomes compared to those without; however, unlike previous retrospective studies, moderate calcium resulted in similar outcomes as none/mild calcium.

BACKGROUND: We examined the outcomes of older adults undergoing nontrans-femoral (non-TF) transcatheter aortic valve replacement (TAVR) procedures including trans-apical (TA), trans-aortic (TAo), trans-subclavian (TSub), and trans-carotid (TCa) techniques. METHODS AND RESULTS: This is an observational study of all consecutive older patients who underwent non-TF TAVR for symptomatic severe AS with Edwards Sapien (ES), Medtronic CoreValve, ES3 or Lotus Valve at three centers in France and the United States from 04/2008 to 02/2017. Baseline characteristics and clinical outcomes were defined according to VARC-2 criteria. Of 857 patients who received TAVR, 172 (20%) had an alternative access procedure. Of these, 45 (26%) were TA, 67 (39%) TAo, 17 (10%) TSub, and 43 (25%) TCa procedures. The preference for non-TF access site was different between the two countries (US: TA 39%, TAo 52%, TSub 9%; TCa 0% vs. France: TA 9%, TAo 23%, TSub 11%, and TCa 57%, P-value < .001). Most patients who underwent TAo TAVR were older women (median age: TA 82, TAo 84, TSub 81, TCa 81, P-value = 0.043; female gender: TA 32 (27%), TAo 30 (55%), TSub 10 (41%), TCa 27 (37%), P-value = .021). The predicted Society of Thoracic Surgery risk of mortality was similar among groups (TA 7%, TAo 7%, TSub 6%, TCa 7%, P-value= .738). No differences were observed in the frequency of para-valvular leak, intra-procedural bleeding, vascular complications, conversion to open-heart surgery, or development of acute kidney injury. The highest in-hospital mortality was observed in the TAo group (TA 2%, TAo 15%, TSub 0%, TCa 2%, P-value = .014). However, hospital length of stay, one-month, and one-year mortality were similar among non-TF techniques. CONCLUSION: Although regional differences exist in the choice of alternative access techniques, centers with high technical expertise can provide a safe alternative to traditional TF TAVR. TAo TAVR was associated with higher in-hospital mortality than other non-TF approaches, and this may have reflected patient rather than procedural factors. All alternative access techniques had similar mortality rates and clinical outcomes at one-year follow-up. Trans-carotid access is safe and feasible compared to other non-TF access techniques.

An adolescent male with a recent history of streptococcal pharyngitis presented with severe substernal chest pain, troponin leak, and ST-segment elevation, which are suggestive of acute inferolateral myocardial infarction. The coronary angiogram was normal. The patient was subsequently diagnosed with non-rheumatic streptococcal myocarditis. He was treated with amoxicillin and had excellent recovery. Non-rheumatic streptococcal myocarditis is an important mimic of acute myocardial infarction in young adults.

Severe aortic stenosis (AS) results in considerable morbidity and mortality without aortic valve replacement and is expected to increase in prevalence with the aging population. Because AS primarily affects the elderly, many patients with comorbidities are poor candidates for surgical aortic valve replacement (SAVR) and may not be referred. Transcatheter aortic valve replacement (TAVR) has emerged as transformative technology for the management of AS over the past decade. Randomized trials have established the safety and efficacy of TAVR with improved mortality and quality of life compared with medical therapy in inoperable patients, while demonstrating noninferiority and even superiority to SAVR among high-risk operative candidates. However, early studies demonstrated an early penalty of stroke and vascular complications with TAVR as well as increased paravalvular leak as compared with SAVR. Two device platforms have been evaluated and approved for use in the United States: the Edwards SAPIEN and the Medtronic CoreValve. Early studies also suggest cost-effectiveness for TAVR. Ongoing studies are evaluating new iterations of the aforementioned TAVR devices, novel device designs, and applications of TAVR in expanded populations of patients including those with lower risk profiles as well as those with comorbidities that were excluded from early clinical trials. Future improvements in TAVR technology will likely reduce periprocedural and long-term complications. Further studies are needed to confirm device durability over long-term follow-up and explore the applicability of TAVR to broader AS patient populations.

BACKGROUND: Mitral regurgitation (MR) is the most common valvular disease in the United States and increases the risk of death and hospitalization. The economic burden of MR in the United States is not known. METHODS AND RESULTS: We analyzed inpatient hospitalization data from the 1 221 173 Maryland residents who had any in-state admissions from October 1, 2015, to September 30, 2019. We assessed the total charges for patients without MR and for patients with MR who underwent medical management, transcatheter mitral valve repair or replacement, or surgical mitral valve repair or replacement. During the study period, 26 076 inpatients had a diagnosis of MR. Compared with patients without MR, these patients had more comorbidities and higher inpatient mortality. Patients with medically managed MR incurred average total charges of $23 575 per year; MR was associated with $10 559 more in charges per year and an incremental 3.1 more inpatient days per year as compared with patients without MR. Both surgical mitral valve repair or replacement and transcatheter mitral valve repair or replacement were associated with higher charges as compared with medical management during the year of intervention ($47 943 for surgical mitral valve repair or replacement and $63 108 for transcatheter mitral valve repair or replacement). Annual charges for both groups were significantly lower as compared with medical management in the second and third years postintervention. CONCLUSIONS: MR is associated with higher mortality and inpatient charges. Patients who undergo surgical or transcatheter intervention incur lower charges compared with medically managed MR patients in the years after the procedure.

Background: While there is evidence that patients with low-flow, low-gradient aortic stenosis (AS) benefit from transcatheter aortic valve replacement (TAVR), data are lacking regarding outcomes of patients with a very low gradient (VLG). Methods: In this retrospective, single-center study of patients with severe AS who underwent TAVR, three groups were defined using baseline mean aortic valve gradient: VLG (≤25â mmHg), low gradient (LG, 26-39â mmHg), and high gradient (HG, ≥40â mmHg). The primary outcome was the composite of Kansas City Cardiomyopathy Questionnaire (KCCQ)-12 of <45, decrease in KCCQ-12 of ≥10 compared with baseline, or death at 1 year. Results: One-thousand six patients were included: 571 HG, 353 LG, and 82 VLG. The median age was 82.1 years [interquartile range (IQR) 76.3-86.9]; VLG patients had more baseline comorbidities compared with the other groups. The primary outcome was highest at 1 year in the VLG group (VLG, 46.7%; LG, 29.9%; HG, 23.1%; p = 0.002), with no difference between groups after adjustment for baseline characteristics. At baseline, <30% of VLG patients had an excellent or good (50-100) KCCQ-12, whereas more than 75% and 50% had an excellent or good KCCQ-12 at 30-day and 1-year follow-up, respectively. Conclusion: Although patients with VLG undergoing TAVR have a higher rate of poor outcomes at 1 year compared with patients with LG and HG severe AS, this difference is largely attributable to baseline comorbidities. Patients with severe AS undergoing TAVR have significant improvement in health status outcomes regardless of resting mean gradient.
ABSTRACT
BACKGROUND: Frailty and cognitive impairment (CI) are geriatric conditions that lead to poor health outcomes among older adults with cardiovascular disease. The association between their temporal patterns of development and cardiovascular risk is unknown. OBJECTIVES: This study aims to examine the 5-year cardiovascular outcomes by the pattern of development of frailty and CI in older adults without a history of coronary artery disease. METHODS: We used the National Health and Aging Trends Study, linked to Medicare data. Frailty was measured using the physical frailty phenotype. CI was measured using the AD8 Dementia Screening Interview, measured cognitive performance, or self-report by patient or caregiver for a diagnosis given by a physician. The primary outcome was incident major adverse cardiovascular event at 5 years. RESULTS: Of a total 2,189 study participants aged 65 and older, 38.5% were male. In this study population, 154 (7%) participants developed frailty first, 829 (38%) developed CI first, and 195 (9%) participants developed both simultaneously (frail-CI group). Those who developed frailty and CI simultaneously were older, more likely to be female, and had multiple chronic conditions. The frail-CI group had the highest risk of major adverse cardiovascular event (hazard ratio [HR]: 1.81; 95% CI: 1.47-2.23) followed by frail first (HR: 1.46; 95% CI: 1.17-1.81) and CI first (HR: 1.31; 95% CI: 1.15-1.50). Frailty first was associated with the greater risk of stroke (HR: 1.49; 95% CI: 1.06-2.09) compared to the intact group. CONCLUSIONS: The simultaneous development of frailty and CI is associated with an increased risk of adverse cardiovascular outcomes including death compared with the development of each syndrome alone. Diagnostics to detect frailty and CI are critical in assessment of cardiovascular risk in the older population.
ABSTRACT
INTRODUCTION AND IMPORTANCE: Atrial myxomas account for more than half of all cardiac tumors. While the symptoms of these are many, the most prominent among them being migraines, heart failure, dyspnea, and chest pain thereby making a diagnosis all the more difficult. CASE PRESENTATION: A 53-year-old woman presented with a recent onset of headaches with aura. The latter was triggered by exercise and physical exertion. Taking Ibuprofen 800 mg three times daily provided relief to the patient. Headaches were associated with photophobia and nausea. CLINICAL DISCUSSION: The patient had the typical triad of symptoms, namely (i) obstructive (light headedness, near syncope, dyspnea, chest pain), (ii) embolic (transient ischemic attacks - TIA, peripheral arterial claudication), and (iii) constitutional (fever, malaise, weight loss). Cerebral infarction is the most frequent complication. The patient had multiple embolic acute and sub-acute infarcts. The aura and headaches were resolved following resection of the myxoma. CONCLUSION: Atrial myxomas must enter the differential diagnosis in the case of a patient presenting with migraines associated with aura. In particular, those whose headaches increase with physical exertion require further investigation.
ABSTRACT
With the aging of the world's population, a large proportion of patients seen in cardiovascular practice are older adults, but many patients also exhibit signs of physical frailty. Cardiovascular disease and frailty are interdependent and have the same physiological underpinning that predisposes to the progression of both disease processes. Frailty can be defined as a phenomenon of increased vulnerability to stressors due to decreased physiological reserves in older patients and thus leads to poor clinical outcomes after cardiovascular insults. There are various pathophysiologic mechanisms for the development of frailty: cognitive decline, physical inactivity, poor nutrition, and lack of social supports; these risk factors provide opportunity for various types of interventions that aim to prevent, improve, or reverse the development of frailty syndrome in the context of cardiovascular disease. There is no compelling study demonstrating a successful intervention to improve a global measure of frailty. Emerging data from patients admitted with heart failure indicate that interventions associated with positive outcomes on frailty and physical function are multidimensional and include tailored cardiac rehabilitation. Contemporary cardiovascular practice should actively identify patients with physical frailty who could benefit from frailty interventions and aim to deliver these therapies in a patient-centered model to optimize quality of life, particularly after cardiovascular interventions.

BACKGROUND: The Evolut Low Risk Trial (Medtronic Evolut Transcatheter Aortic Valve Replacement in Low Risk Patients) showed that transcatheter aortic valve replacement (TAVR) with a supra-annular, self-expanding valve was noninferior to surgery for the primary endpoint of all-cause mortality or disabling stroke at 2 years. This finding was based on a Bayesian analysis performed after 850 patients had reached 1 year of follow-up. OBJECTIVES: The goal of this study was to report the full 2-year clinical and echocardiographic outcomes for patients enrolled in the Evolut Low Risk Trial. METHODS: A total of 1,414 low-surgical risk patients with severe aortic stenosis were randomized to receive TAVR or surgical AVR. An independent clinical events committee adjudicated adverse events, and a central echocardiographic core laboratory assessed hemodynamic endpoints. RESULTS: An attempted implant was performed in 730 TAVR and 684 surgical patients from March 2016 to May 2019. The Kaplan-Meier rates for the complete 2-year primary endpoint of death or disabling stroke were 4.3% in the TAVR group and 6.3% in the surgery group (P = 0.084). These rates were comparable to the interim Bayesian rates of 5.3% with TAVR and 6.7% with surgery (difference: -1.4%; 95% Bayesian credible interval: -4.9% to 2.1%). All-cause mortality rates were 3.5% vs 4.4% (P = 0.366), and disabling stroke rates were 1.5% vs 2.7% (P = 0.119), respectively. Between years 1 and 2, there was no convergence of the primary outcome curves. CONCLUSIONS: The complete 2-year follow-up from the Evolut Low Risk Trial found that TAVR is noninferior to surgery for the primary endpoint of all-cause mortality or disabling stroke, with event rates that were slightly better than those predicted by using the Bayesian analysis.

The use of transcatheter aortic valve implantation (TAVI) has greatly increased over the past 2 decades and now has overtaken surgical aortic valve replacement. We have limited data regarding the long-term durability of TAVI and the predictors of survival. Calcification, inflammation, fibrous tissue deposition, and mechanical stress are important in the structural deterioration of surgical bioprosthetic valves and likely contribute to TAVI durability. However, TAVI has several differences to surgical valve replacement such as valve preparation, valve to native anatomy interaction, and valve sizing which all likely contribute to durability and long-term survival. Most procedures have been performed on older patients and therefore long-term follow-up studies have noted mortality of approximately 50% at 5 years and 75% by 7 years. Current data are limited by the high mortality of patients who have received TAVI often as a result of age, frailty, and other competing comorbidities. TAVI as compared with surgical valve replacement is associated with several differences including higher conduction abnormalities (i.e., need for pacemakers) and paravalvular leak, both of which may affect long-term morbidity and mortality.

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.
