Huded CP, et al. - Researchers investigated the incremental prognostic impact of baseline valvuloarterial impedance (Zva) and left ventricular global longitudinal strain (LV-GLS) in patients with severe aortic stenosis (AS) and preserved LV ejection fraction (LVEF) treated with surgical aortic valve replacement (AVR). It was determined that higher Society of Thoracic Surgeons score, higher Zva and worse LV-GLS were independently related to long-term survival. Individuals with severe AS and preserved LVEF treated with surgical AVR, baseline Zva and LV-GLS conferred improved risk stratification and yielded synergistic prognostic value.
