Early Stroke Volume Variation After Transcatheter or Surgical Aortic Valve Replacement Predicts Clinical Outcomes in Low-Flow Aortic Stenosis.

ABSTRACT:

Background

Little is known about stroke volume index (SVi) change and its prognostic implication in patients with low-flow aortic stenosis (AS) undergoing aortic valve replacement (AVR) and conflicting results are present in literature. The aim of this study was to evaluate the postoperative change in SVi and its impact on outcomes in patients with low-flow severe AS undergoing AVR.

Methods

Retrospective observational study of a high-volume tertiary care center including consecutive patients with low-flow (SVi ≤ 35 mL/m²) severe AS who underwent AVR (either surgical or transcatheter) with available comprehensive pre- and post-AVR echocardiographic assessment. Post-AVR SVi improvement was defined as an increase ≥ 15% from baseline, while SVi normalization was defin
