Background: Cardiac amyloidosis (CA) and hypertrophic cardiomyopathy often manifest with overlapping clinical features, making diagnosis and management challenging.

Case Summary: We describe a 79-year-old man presenting with exertional dyspnea and presyncope who was diagnosed with transthyretin CA with left ventricular outflow tract (LVOT) obstruction and was treated with concurrent mavacamten and tafamidis.

Discussion: There is substantial overlap in the clinical phenotypes of hypertrophic cardiomyopathy and CA, and the presence of hemodynamically significant LVOT does not exclude the possibility of CA as an underlying diagnosis.

Background: Identifying severe aortic stenosis can be difficult especially among patients with low-flow states compared to normal flow. Non-invasive modalities can aid in the diagnosis for timely treatment.

Methods: In this retrospective, single-center study of patients with aortic stenosis who underwent transcatheter aortic valve replacement (TAVR), we calculated stroke volume using CT blood pool based (CT-blp) analysis, echocardiogram and right heart catheterization (cath) performed before TAVR.

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 (≤25 mmHg), low gradient (LG, 26-39 mmHg), and high gradient (HG, ≥40 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.

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.

Calcific aortic valve disease, a condition of chronic inflammation, is associated with increased cardiovascular events and all-cause mortality. Omega-3 fatty acids (O3FAs) reduce both acute and chronic inflammation, but their associations with aortic valve calcium (AVC) have not been studied. The Multi-Ethnic Study of Atherosclerosis is a prospective cohort study of 6,814 adults without clinical cardiovascular disease.

Background: Greater insight into sex-based differences in health status can lay the foundation for more equitable health care. This study compares differences in health status of women and men in the CPORT-E trial (Cardiovascular Patient Outcomes Research Team Non-Primary Percutaneous Coronary Intervention) undergoing nonprimary percutaneous coronary intervention.

Methods: We compared Seattle Angina Questionnaire scores at baseline, 6 weeks, and 9 months for 6851 women and 12 016 men undergoing nonprimary percutaneous coronary intervention.

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.

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.

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.

Patients with influenza infection are at increased risk of acute myocardial infarction (AMI). There are limited data on the short-term prognosis and management of patients with AMI and concomitant influenza. We examined the National Inpatient Sample from 2010 to 2014 for adult patients with a diagnosis of AMI.

Background: The CPORT-E trial showed the noninferiority of nonprimary percutaneous coronary intervention (PCI) at hospitals without cardiac surgery on-site (SoS) compared with hospitals with SoS for 6-week mortality and 9-month major adverse cardiac events (MACE). However, target vessel revascularization (TVR) was increased at non-SoS hospitals. Therefore, we aimed to determine the consistency of the CPORT-E trial findings across the spectrum of enrolled patients.

Aortopathies pose a significant healthcare burden due to excess early mortality, increasing incidence, and underdiagnosis. Understanding the underlying genetic causes, early diagnosis, timely surveillance, prophylactic repair, and family screening are keys to addressing these diseases. Next-generation sequencing continues to expand our understanding of the genetic causes of heritable aortopathies, rapidly clarifying their underlying molecular pathophysiology and suggesting new potential therapeutic targets.

Valvular aortic stenosis (AS) is a progressive disease that affects 2% of the population aged 65 years or older. The major cause of valvular AS in adults is calcification and fibrosis of a previously normal tricuspid valve or a congenital bicuspid valve, with rheumatic AS being rare in the United States. Once established, the rate of progression of valvular AS is quite variable and impossible to predict for any particular patient.

Background: Adherence to dual antiplatelet therapy (DAPT) is critical after coronary stenting. Although adherence rates are frequently assessed in clinical trials, adherence rates in the unselected population recommended for treatment but beyond clinical trials are largely unknown. Therefore, we performed a systematic review of published observational studies to describe rates of DAPT adherence, trends in DAPT use over time, and patient-level factors associated with nonadherence.
