Novel Transvalvular Flow Criteria Reduce Indeterminate Stress Echocardiography and Refine Risk Stratification in Low-Gradient Aortic Stenosis.

BACKGROUND Guidelines advocate the use of dobutamine stress echocardiography (DSE) in low-gradient aortic stenosis (aortic valve area [AVA] <1 cm2 with aortic valve mean gradient <40 mm Hg) with reduced left ventricular ejection fraction (<50%) for subsequent patient management. A significant proportion of patients hav...

Aortic valve replacement in patients with small aortic annuli: a systematic review and network meta-analysis.

Objectives Up to 40% of patients with aortic stenosis undergoing valve replacement have a small annulus, a key determinant of valve hemodynamics, durability, and clinical outcomes. Surgical and transcatheter approaches have been reported to be determined by prosthesis design, considering the operative mortality and mor...

Impact of Atrial Fibrillation on Long-Term Outcomes of Aortic Stenosis.

In this large cohort with AS, AF was independently associated with an increased risk of both all-cause and cardiovascular mortality, regardless of treatment strategy or AS flow-gradient pattern.

Review Jul 2026

The role of selective multidetector computed tomography after transcatheter aortic valve implantation.

The role of multimodality imaging in identifying thrombogenic valve phenotypes is examined and a pragmatic imaging framework integrating echocardiography with selective multidetector computed tomography is proposed to support individualized post-TAVI surveillance and management.
