Time-interval between maternal hepatic vein Doppler and ECG is longer in late than in early pregnancy

Description : Objectives: Venous Wave Protraction Time (VWPT) is defined as the time-interval between the electrocardiographic P-wave and the corresponding venous Doppler A-wave, as obtained by Duplex Ultrasonography. This study aims to evaluate the gestational evolution of VWPT during uncomplicated pregnancy. M...

Venous wave protraction time is shorter in pre-eclampsia than in normal third trimester pregnancy

Description : Background: Venous pulse waves, as obtained by Duplex Ultrasonography, are a reflection of cardiac right atrial function. The time-interval between cardiac electrocardiographic (ECG) signals and venous Doppler waves is the so-called Venous Wave Protraction Time (VWPT). Aim: To compare Hepatic Ve...

Time-interval between maternal electrocardiogram and venous Doppler waves in normal pregnancy and pre-eclampsia: a pilot study.

Description : Purpose: To evaluate the time-interval between maternal electrocardiogram (ECG) and venous Doppler waves at different stages of uncomplicated pregnancy (UP) and in pre-eclampsia (PE). Materials and Methods: Cross-sectional pilot study in 40 uncomplicated singleton pregnancies, categorized in four g...

Role of dysfunctional maternal venous hemodynamics in the pathophysiology of pre-eclampsia: a review

Description : The venous compartment has an important function in regulation and control of cardiac output. Abnormalities of cardiac output have been found in early gestational stages of both early-and late-onset pre-eclampsia. The venous compartment also maintains the balance between circulating and non-circulat...

Orthostatic challenged cardiac contractility in pre-eclampsia, as measured by impedance cardiography

Description : Aim: To evaluate maternal cardiac contractility following orthostatic challenge in normal pregnancy (NP) and pre-eclampsia (PE) using impedance cardiography (ICG). Methods: 16 women with NP, 12 with early-onset PE (EPE) and 14 with late-onset PE (LPE) underwent a consecutive series of ICG-examinatio...

Vascular pulse transit time in normal pregnancy and pre-eclampsia : a new parameter for measurement of vascular tone ?

Description : Aim: To evaluate venous and arterial pulse transit times, defined as time-interval between maternal ECG and sonographic Doppler waves (EDT) or impedance cardiogram (ICG), in normal pregnancy (NP) and pre-eclampsia (PE). Methods: 16 women with (NP), 12 with early-onset (EPE) and 14 with late-onset (...

Venous Pulse Transit Time in Normal Pregnancy and Preeclampsia

Description : Uncomplicated pregnancies (n = 16) were evaluated longitudinally and compared to early-(n = 12) and late-onset (n = 14) preeclampsia patients, assessed once at diagnosis. Pulse transit time (PTT), equivalent to pulse wave velocity, was measured as the time interval between corresponding characterist...

Interlobar venous flow is different between left and right kidney in uncomplicated third trimester pregnancy

Description : Aim: To investigate Doppler flow patterns of renal interlobar veins (RIV) in left (L) and right (R) kidney in relation to gestational age and to intrarenal pyelocalyceal diameters (PCD). Methods: Cross-sectional study involving 6 groups of women: (1) non-pregnant women, women pregnant betwee...
