The echocardiographic parameters assessing diastolic function include: 3. Pulmonary vein pulsatility index (PVPI): This is obtained by the Doppler ratio of peak systolic velocity, peak presystolic velocity, and mean velocity in the pulmonary venous flow.
The echocardiographic parameters assessing diastolic function include: 2. Left atrial shortening fraction (LASF): This is obtained by the M-mode ratio of the maximal left atrial diameter and the minimal left atrial diameter.
The echocardiographic parameters assessing diastolic function include: 1. Excursion index of the septum primum (EI): This is the ratio between the maximal linear displacement of the atrial flap valve and the left atrial diameter.
The measurement of parameters such as the duration of the isovolumetric contraction wave (IVC), ejection time (ET), isovolumetric relaxation time (IVR), and myocardial performance index (MPI) allows fetal cardiac diastolic function. https://t.co/O8xioe37mU
