Echocardiographic Assessment of Pulmonary Arteries Pulsatility Index in Fontan Circulation
BACKGROUND Late complications after Fontan procedure may be due to the absence of pump and pulsatile pulmonary blood flow in this type of palliation. Our aim was to quantify the degree of pulsation by echocardiographic method in patients with extracardiac total cavopulmonary connection (ECTCPC) in comparison with biventricular circulation and few cases of pulsatile Fontan. METHODS In a case s...
متن کاملFetal middle cerebral artery and umbilical artery pulsatility index: effects of maternal characteristics and medical history.
OBJECTIVE To define the contribution of maternal variables which influence the measured fetal middle cerebral artery (MCA) and umbilical artery (UA) pulsatility index (PI) in the assessment of fetal wellbeing. METHODS Maternal characteristics and medical history were recorded and fetal MCA-PI and UA-PI (n = 36,818) were measured in women with singleton pregnancies attending a routine hospital...
متن کاملUterine artery pulsatility index in hypertensive pregnancies: When does the index normalize in the puerperium?
OBJECTIVE To investigate whether the uterine artery pulsatility index (UtA PI) of hypertensive pregnancies is higher than that of normal pregnancies in the puerperium, as well as in the antepartum period. METHODS The UtA PI was measured in hypertensive (group 1) and normal pregnancies (group 2) during antepartum, immediate postpartum or late postpartum periods. Using the transvaginal approach...
متن کاملHomocysteine and pulsatility index of cerebral arteries.
BACKGROUND AND PURPOSE A pulsatility index (PI) represents vascular resistance distal to an examined artery. The purpose of the present study was to evaluate an association between plasma total homocysteine (tHcy) and PIs of the cerebral arteries in patients with ischemic stroke. METHODS Consecutive patients with ischemic stroke referred to a neurovascular ultrasound laboratory were evaluated...
متن کاملFetal umbilical artery Doppler pulsatility index and childhood neurocognitive outcome at 12 years
OBJECTIVE To determine whether an elevated fetal umbilical artery Doppler (UAD) pulsatility index (PI) at 28 weeks' gestation, in the absence of fetal growth restriction (FGR) and prematurity, is associated with adverse neurocognitive outcome in children aged 12 years. METHODS Prospective cohort study, comparing children with a normal fetal UAD PI (<90th centile) (n=110) and those with an ele...
