TL;DR: In this article, the authors examined the recovery time of left atrial mechanical function after electrical cardioversion of atrial fibrillation, and found that active atrial systolic and relaxant variables obtained from transmitral and pulmonary venous flow velocities may reflect left arterial mechanical function.

TL;DR: Combined analysis of the LVIF and PVF provides useful information regarding various abnormalities of left ventricular diastolic hemodynamics in patients with HCM.

TL;DR: Evaluated pulmonary venous flow is helpful in understanding hemodynamic events between the left atrium and left ventricle in patients with mitral stenosis and a significant negative correlation between the peak diastolic flow velocity of the PVF and the pressure half time from transmitral flow obtained by continuous wave Doppler is demonstrated.

TL;DR: Evaluated the contribution of eccentric left ventricular hypertrophy and its related organic and spatial abnormalities of the mitral complex to the occurrence of mitral regurgitation in patients with hypertrophic cardiomyopathy found it to be significantly greater in the obstructive group than the nonobstructive group.

TL;DR: R-L shunt flow was detected in patients with atrial septal defects not only with pulmonary hypertension but also without pulmonary hypertension and was influenced by the right atrial pressure in the phase of tricuspid valve closing, the volume or direction of trICuspid regurgitation, rebound flow caused by massive left-to-right shunt Flow, the grade of right ventricular distensibility or the complication of pulmonary hypertension, and complications with other cardiac anomalies.
