Association of Time Between Left Ventricular and Aortic Systolic Pressure Peaks With Severity of Aortic Stenosis and Calcification of Aortic Valve

Abstract

Prolonged TLV-Ao was associated with severe AVC. This catheter-based hemodynamic index may be an additional surrogate to differentiate low-gradient true severe AS. Larger, prospective studies investigating the role of TLV-Ao as a marker of clinical outcomes in patients undergoing TAVR are required.
