Study Shows Aortic Valve Replacement Was Associated With Better Outcomes in Patients with Low-Gradient Aortic Stenosis and Preserved Left Ventricular Ejection Fraction Compared With High-Gradient Aortic Stenosis Analysis of PARTNER 2A randomized trial and SAPIEN 3 registry

A recent study by Dr. Salaun, published in Circulation: Cardiovascular Interventions, demonstrated that aortic valve replacement in patients with the low gradient (LG, defined as mean gradient <40 mmHg) severe aortic stenosis (AS) and preserved ejection fraction (EF) has resulted in better outcomes versus in those with the high gradient (HG, defined as a mean transvalvular gradient (MG) 40 mmHg) AS. Also, the study revealed that patients with classical low flow, low gradient (CLF-LG, defined as MG <40 mmHg and LVEF <50%) AS were at higher risk of death, rehospitalization, or stroke at 2 years.

ADRIFT Study: Reduced Rivaroxaban Doses Are Associated With Lower Thrombin Generation Following Percutaneous Left Atrial Appendage Closure Compared to Dual Antiplatelet Therapy

A recent study by Dr. Duthoit, MD, published in Circulation: Cardiovascular Interventions, showed that compared to dual antiplatelet therapy, nonvitamin k antagonist monotherapy using a reduced dose of rivaroxaban (10 and 15 mg) in patients undergone left atrial appendage closure was associated with lower thrombin generation. This data supported that reduced rivaroxaban doses could be a substitute for the antithrombotic medications currently used after this procedure. Continue reading

DAPA-HF Trial: Compared to Placebo, Dapagliflozin Was Beneficial in Patients with Heart Failure and Reduced Ejection Fraction Regardless of Background Diuretic Therapy

A recent study by Dr. Alice M. Jackson M.D., published in Circulation journal, showed that the use of dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, in patients with reduced ejection fraction heart failure (HF) is associated with reduced risk of cardiovascular (CV) death or a worsening HF event, and all-cause death. These effects remained consistent among different subgroups of diuretic therapy.
