Prognostic Value of Echocardiographic-derived Stroke Volume in Severe Primary Mitral Regurgitation

Studies have demonstrated the importance of forward flow, and specifically of stroke volume (SV) and SV index (SVI), as prognostic markers in different cardiovascular diseases. Here we aimed to evaluate the association between SV and SVI thresholds and prognosis in patients with severe primary mitra...

Description
Summary:Studies have demonstrated the importance of forward flow, and specifically of stroke volume (SV) and SV index (SVI), as prognostic markers in different cardiovascular diseases. Here we aimed to evaluate the association between SV and SVI thresholds and prognosis in patients with severe primary mitral regurgitation (MR). The association between either SV (70ml) or SVI (35mL/m²) thresholds and all-cause mortality and heart failure (HF) hospitalizations was examined in a retrospective analysis of 283 patients (60% male, median age 70 years, IQR 58-82) with severe primary MR, normal left ventricular size and systolic function and no other significant left-sided valvular abnormalities. Compared with normal values, SV
