Discrepancies in Measurement of the Thoracic Aorta: JACC Review Topic of the Week
Review Article | By JA Elefteriades, SK Mukherjee, H Mojibian et al.
Clinicians often encounter discrepant measurements of the ascending aorta that impede, complicate, and impair appropriate clinical assessment—including key issues of presence or absence of aortic growth, rate of growth, and need for surgical intervention. These discrepancies may arise within a single modality (computed tomography scan, magnetic resonance imaging, or echocardiography) or between modalities. The authors explore the origins an...
Precision Medicine in TAVR: How to Select the Right Device for the Right Patient
Editorial | By G Marquis-Gravel, S Vemulapalli, AW Asgar et al.
Transcatheter aortic valve replacement (TAVR) represents a first-line option for the treatment of patients with severe symptomatic aortic stenosis across the entire spectrum of surgical risks. Given the expected growth of TAVR procedures in low-risk patients, many factors other than the primary endpoints of pivotal TAVR trials (either death, or the composite of death or stroke) need to be considered during the selection ...
Post-Discharge Bleeding and Mortality Following Acute Coronary Syndromes With or Without PCI
Original Research | By G Marquis-Gravel, F Dalgaard, AD Jones et al.
BACKGROUND - The long-term prognostic impact of post-discharge bleeding in the unique population of patients with acute coronary syndrome (ACS) treated without percutaneous coronary intervention (PCI) remains unexplored. OBJECTIVES - The aim of this study was to assess the association between post-discharge bleeding and subsequent mortality after ACS according to index strategy (PCI or no PCI) and t...

IMPORTANCE - Data are limited regarding statin therapy for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in adults 75 years and older. OBJECTIVE - To evaluate the role of statin use for mortality and primary prevention of ASCVD in veterans 75 years and older. DESIGN, SETTING, AND PARTICIPANTS - Retrospective cohort study that used Veterans Heal...

BACKGROUND - The prognostic significance of periprocedural myocardial infarction (MI) remains controversial. METHODS AND RESULTS - The study aims to investigate the incidence of periprocedural MI in the era of high sensitivity diagnostic markers and intense antithrombotics, and its impact on early outcomes of patients with acute MI treated with primary angioplasty (pPCI). Data from the PRA...
Acute Coronary Syndrome, Antiplatelet Therapy, and Bleeding: A Clinical Perspective
Transcatheter Aortic Valve Replacement in Patients With Multivalvular Heart Disease
Review Article | By F Khan, T Okuno, D Malebranche et al.
As transcatheter aortic valve replacement becomes a more dominant treatment option across all risk profiles, the frequency of encountering patients with multivalvular disease will increase. Furthermore, percutaneous interventions to treat other valvular lesions are also evolving. Understanding the clinical implications and treatment options for a second valvular lesion is becoming increasingly important to guide heart team decisions, and this p...

Dual antiplatelet therapy reduces ischemic events in cardiovascular disease, but it increases bleeding risk. Thrombin receptors PAR1 and PAR4 are drug targets, but the role of thrombin in platelet aggregation remains largely unexplored in large populations. We performed a genome-wide association study (GWAS) of platelet aggregation in response to full-length thrombin, followed by clinical association analyses, Mendelian ra...

Bioprosthetic valve oversizing is associated with increased risk of valve thrombosis following TAVR
Original Research | By TF Simpson, CV Tuohy, K Rajotte et al.
BACKGROUND - Hypoattenuating leaflet thickening (HALT), the radiographic manifestation of transcatheter heart valve thrombosis, is commonly identified following transcatheter aortic valve replacement (TAVR) and associated with increased risk of stroke and structural valve deterioration. While anticoagulation effectively resolves HALT, routine use remains controversial. We aimed to identify hemodynamic, anatomic, and co...
