Open AccessPrognostic value of left atrial volume index in degenerative mitral stenosis
Degenerative mitral stenosis (DMS) is associated with a poor prognosis. Although mean transmitral gradient (TMG) has shown a good correlation with outcome, little is known about the association between other e...

Optimal vortex formation time index in mitral valve stenosis
Left ventricular vortex formation time (VFT) is a novel dimensionless index of flow propagation during left ventricular diastole, which has been demonstrated to be useful in heart failure and cardiomyopathy. I...

Inadequately low left ventricular mass in patients with significant aortic stenosis predicts favourable prognostic outcomes
In patients with significant aortic stenosis (AS), the prognostic effect of the increase in left ventricular mass (LVM) in relation to one’s hemodynamic load has been described. Inappropriately high LVM has be...

Echocardiographic discrepancies in severity grading of aortic valve stenosis with left ventricular outflow tract (LVOT) cut-off values in an Asian population
Inconsistencies in grading of aortic stenosis (AS) severity have been reported. However, it remains to be studied in an Asian population. We investigated consistency of grading AS severity at various left vent...

Clinical and echocardiographic features of paradoxical low-flow and normal-flow severe aortic stenosis patients with concomitant mitral regurgitation
Mitral regurgitation (MR) coexists in a significant proportion of patients with severe aortic stenosis (AS), and portends inferior therapeutic outcomes. In severe AS, MR is thought to contribute to a low-flow ...
