OBJECTIVE: The cardiovascular system maintains homeostasis through a series of adaptive responses to physiological requirements. However, little is known about the adaptation of fetal cardiac function to gravity, according to gestational age. In the present study, we aimed to evaluate the adaptive responses of cardiac function to postural changes, using Tei index measurements. METHODS: Fetal echocardiography and Doppler examination were performed on 114 women with vertex singleton pregnancies at 19 to 40 weeks' gestation...

: Purpose: To evaluate pre- and postprocedural myocardial function in fetuses with moderate to severe congenital diaphragmatic hernia (CDH) who underwent FETO to improve survival and to reduce morbidity and to compare these data with fetuses and CDH not undergoing FETO and normal controls. Materials and Methods: 8 fetuses with isolated left-sided CDH were included and underwent FETO at our center between 2012 and 2013. Prior to and after the operation, myocardial function was assessed by measuring the mitral annular plane systolic excursion (MAPSE), the tricuspid annular plane systolic excursion (TAPSE), Tei index, isovolumetric contraction time (ICT), ejection time (ET), isovolumetric relaxation time (IRT) for the left ventricle in PW Doppler ultrasound as well as ICT, ET, IRT and Tei index in pulsed wave tissue Doppler imaging (PW-TDI) for the left and right ventricle...

BACKGROUND: The functionally single fetal right ventricle demonstrates reduced longitudinal relative to circumferential contraction velocities and deformation, a pattern similar to the normal fetal left ventricle. Altered diastolic properties are also present, with greater reliance on atrial contraction for right ventricular filling. It is unknown whether the functionally single left ventricle (SLV) demonstrates similar altered deformation patterns and diastolic properties. METHODS: Echocardiograms from 29 fetuses with SLVs were retrospectively compared with those from 48 controls with appropriately grown left ventricles...

OBJECTIVES: To evaluate changes in myocardial contractility that occur after selective laser photocoagulation of communicating vessels (SLPCV) in fetuses from pregnancies complicated with twin-to-twin transfusion syndrome (TTTS). METHODS: The study included 51 pregnant women between 16 and 26 weeks of gestation who underwent SLPCV due to TTTS. Ultrasonography was performed before SLPCV and on postoperative day 1, 3(4) and 7. Fetal heart contractility in both fetuses was evaluated by determining the shortening fractions of the left and right ventricles (FS LV and FS RV), and the myocardial performance index (Tei-Index)...

OBJECTIVE: To investigate the effect of different operation time to percutaneous balloon pulmonic valvuloplasty (PBPV) to critical pulmonary valve stenosis (CPS). METHOD: Twenty-one infants (age ≤ 60 days at operating day) suffered from CPS, diagnosed by fetal echocardiogram and confirmed by echocardiography after birth, were enrolled in this case-control-study with written informed consent during April 2007 to December 2011. Of the 21 cases, 7 had prenatal diagnosis in our prenatal diagnosis center (prenatal group, Pre) and 14 were referred from other hospitals, who were divided into postpartum group A (Post A, referred within 28 days after birth) and postpartum group B (Post B, referred 29 to 60 days after birth)...

A 22-week fetus presented with a large left ventricular aneurysm, 24 × 21 × 18 mm in size, detected by abnormal four-chamber view, and severe fetal hydrops with pericardial effusion, ascites and skin edema. The aneurysm was thin-walled, hypokinetic, and had enlarged with gestational age, causing compression of the lung. Although the left ventricular function had progressively impaired as expressed by increase in Tei index, hydrops had resolved by 32 weeks of gestation, probably because of maternal digoxin therapy and successful compensation by the right ventricle, as represented by retrograde blood flow in the distal aortic arch via the patent arterial duct...

Hemodynamic study was performed on a 32-year-old woman presenting at 27 weeks' gestation. Ultrasound revealed a single normal fetus with mild cardiomegaly, polyhydramnios, and placental chorioangioma. Doppler study showed increased middle cerebral artery peak systolic velocity, normal Tei index, and forward flow of "a" wave with normal preload in the ductus venosus. Twelve hours after initiation of indomethacin for tocolysis, frank hydrops fetalis developed rapidly. The right ventricle showed poor contractility and performance...

Myocardial performance index (MPI), or Tei index, has become a commonly used parameter for the noninvasive, Doppler-derived assessment of global systolic and diastolic performance of the heart in both adults and children. Normal values have been established in adults and children; however, limited data exist in fetal hearts. The aim of this study was to further elucidate normal values of fetal left (LV) and right ventricle (RV) MPI values in second- and third-trimester fetuses and compare these values with other previously published data...

BACKGROUND: The systemic right ventricle in palliated hypoplastic left heart syndrome (HLHS) has relatively reduced longitudinal compared with circumferential deformation, a pattern of contraction more akin to the normal left ventricle, which presumably improves right ventricular (RV) pumping efficiency. The aim of this study was to test the hypothesis that these changes in the RV contraction pattern in infants with HLHS are present prenatally. METHODS: Echocardiograms from 48 fetuses with HLHS were retrospectively compared with those from appropriately grown RV and left ventricular controls...

OBJECTIVE: We sought to better define echocardiographic predictors of perinatal mortality in fetuses with Ebstein's anomaly (EA) or tricuspid valve dysplasia (TVD). METHOD: Parameters included measured chamber size, the presence of hydrops, and Doppler recordings of the left ventricular (LV) myocardial performance index (MPI). RESULTS: Between 1 January 2000 and 31 December 2008, 21 fetuses were diagnosed with either EA (17) or TVD (4). Five fetuses were lost to follow-up, and 12 of 16 fetuses were born live (75%)...
