    Correlation between plasma brain natriuretic peptide levels and left atrial appendage flow velocity in patients with non-valvular atrial fibrillation and normal left ventricular systolic function

    The left atrial appendage (LAA) flow velocity is an important factor for thrombus formation in patients with non-valvular atrial fibrillation (NV-AF). Recently, the relation of plasma brain natriuretic peptide...

    Assessment of left ventricular diastolic function using color kinesis: differentiation between normal and pseudonormalized patterns

    Doppler examination of transmitral flow has been widely used to noninvasively assess left ventricular (LV) diastolic function. However, it has been demonstrated that transmitral flow velocity is dependent on L...

    Evaluation of left ventricular diastolic function using color kinesis

    Color kinesis (CK) is a real-time echocardiographic technique based on acoustic quantification that yields regional and global information by tracking and color-encoding endocardial motion. The aim of this stu...
