Fetal myocardial index during labor

Abstract

BACKGROUND: The Myocardial Performance Index (MPI) is a Doppler derived myocardial function tool and can be used to evaluate systolic and diastolic function in fetuses. The objectives of this study were to investigate the MPI during labor and compare it to values in non-laboring women.

METHODOLOGY: 40 women with uncomplicated, term, singleton pregnancies were recruited to this prospective observational study at Thomas Jefferson University Hospital. Controls were a retrospective cohort of women > 34 weeks who underwent third trimester fetal echocardiography. Fetal left and right sided isovolumic contraction time, isovolumic relaxation time and ejection time were recorded before, during and after contractions. Right and left sided MPI was then calculated.

RESULTS: Laboring patients and non-laboring patients were comparable for age, race, gravidity and parity. During labor the average left MPI was 0.63 ± 0.17 and the average right MPI was 0.62 ± 0.20. The coefficient of correlation between MPI and cervical dilation was 0.15 for left MPI Index and 0.14 for right MPI. When comparing non-laboring to laboring women, the average left MPI for non-laboring women was 0.34 ± 0.04, p = <0.001.

CONCLUSIONS: Myocardial Performance Index is a non-invasive, easily attainable measure of cardiac function that can be obtained during labor and does not change with cervical dilation. MPI is significantly different between laboring and non-laboring women. The fetal MPI may help define fetal status in labor.

Heart Tumors in 33 Fetuses - Review of Twenty-Two Years of the Single-Centre Experience

Abstract

INTRODUCTION: Cardiac tumors (CT) have been diagnosed since the eighties of the last century. The three most commonly diagnosed types of CT are rhabdomyomas, teratomas and fibromas. Severe fetal disturbances, such as arrythmias, fetal hydrops, ventricular obstructions, may be associated with the heart tumor.

AIM OF THE STUDY: To present the key role of the echocardiographic examination in the perinatal care and to present some demographic changes in this population of the youngest patients.

MATERIAL AND METHODS: From the Filemaker database of the Department for Diagnosis and Prevention of Congenital Malformations, Polish Mother’s Memorial Hospital & Medical University of Lodz, all cases with prenatal diagnoses of cardiac tumor in singleton pregnancy were compiled over a 22-year period (1993–2015). 33 cases of heart tumors in fetuses had 72 fetal echo examinations. The average number of cases per year was 1,5 (range 1 – 5). The retrospective analysis of the material was performed using the Statistica package. The analysis included the assessment of the cardiovascular condition defined by Cardiovascular Profile Score, location and number of tumors; age, past obstetric history, place of residence of the mother, type of delivery and neonatal follow-up.

RESULTS: The number of fetuses with cardiac tumor cases did not increase during this period. The maternal age was 28,1 years (± 5,2 years) and was decreasing over time. The primigravidae constituted 60% of examined population. The history of past miscarriages was observed in 26% of women. The majority of tumors were detected and diagnosed in the third trimester – at mean 29,6 hbd, but the diagnosis was made earlier in the past decades (regression analysis, p=0,042). The average duration of pregnancy was 36,6 hbd (range: 27-42 hbd). There was no statistical difference between decades in term on pregnancy duration.

The cardiac tumors were more frequent in the female fetuses (71,4% to 28,6%; X2 test; p=0,006). The proportions between the groups of single and multiple tumors changed in last five years – currently the multiple tumors are more frequent (87,5%). The mortality in the group of single tumors was twice as high as in the group of multiple tumors. The percentage of cesarean sections between 1993 and 2005 was 67% and between 2006 and 2015 was 75% (p=0,63). The mortality of neonates with cardiac tumors declined over the period taken into account.

CONCLUSIONS: The perinatal care of the fetuses with cardiac tumors improved over last 20 years. The characteristics of analyzed population had shown that fetal CTs affected healthy, young mothers, more often primigravidae, more often female fetuses. The prevalence of CTs did not increase over time. The gestational age at the time of the diagnosis decreased, thus the period of fetal echo monitoring increased. However, the rate of cesarean sections also increased, which requires further studies and explanations.

Original paper. Do Umbilical Cord Wrapped Around the Fetal Body Can Mimic Signs of Aortal Coarctation?

Abstract

Objectives: Coarctation of the aorta (CoA) is an irreversible congenital heart defect. Its prenatal diagnosis is not rare a subject to false-positive conclusion. We present a novel hypothesis explaining the basis of this error.

Methods: Ten cases of prenatal suspicion of the coarctation of the aorta (based on disproportion at the level of 4 chamber view and mediastinum) coincidenced with the umbilical cord wrapped around the fetal body were found in the Filemaker datebase of the Fetal Cardiology Department. Only single pregnancies were taken into account. In all cases another cardiac and extracardiac malformations were excluded.

Results: The mean maternal age was 29,6 years. The mean gestational age was 33 7/8 weeks. All fetuses were in a good cardiovascular condition. The usual position of the umbilical cord was neck, but they were also location such as nucha, abdomen or lower limb. At birth, all newborns had normal anatomy of the heart. We conclude that the explanation of the false diagnosis was haemodynamic, resulting from the compression of the fetal neck by the umbilical cord that resulted in a disproportion of cardiac blood flow, “mimicking” CoA.

Conclusions:

1. Functional disturbances can mimic prenatal CoA.

2. Umbilical cord position (specially enlacing the fetus neck) should be taken into consideration in suspected cases of fetal CoA.

Prenatal Diagnosis of TAPVC on Monday, Delivery of Tuesday and Cardiac Surgery at Wednesday - A Model of Perinatal Care in 3rd Trimester in Case of Fetal/Neonatal Critical Heart Defect in Tertiary Center.

Abstract

Total anomalous pulmonary venous connection (TAPVC) is a congenital heart defect (CHD), in which all pulmonary veins connect to the systemic veins or to the right atrium/coronary sinus instead of the left atrium. We present a case report of fetus with prenatally diagnosed isolated infracardiac type of TAPVC in 38th week of gestation. In fetal echocardiographic examination performed in the Department of Prenatal Cardiology, the fetus presented lack of visible pulmonary veins connection to left atrium, abnormal venous confluence behind left atrium, additional vein leading from abdominal cavity to mediastinum and abnormal smooth Doppler blood flow in pulmonary confluence. The accurate prenatal diagnosis allowed to deliver the neonate at term, in tertiary center one day after diagnosis, and to perform surgical reposition of pulmonary veins the following day. The neonate was referred home in a good condition after 28 days of hospitalization. This case is a good example of the value of the 3rd trimester echocardiography.

Recommendations for Fetal Echocardiography in Twin Pregnancy in 2016

Abstract

Progress in the fields of fetal cardiology and fetal surgery have been seen not only in singleton pregnancies but also in multiple pregnancies. Proper interpretation of prenatal echocardiography is critical to clinical decision making, family counseling and perinatal management for obstetricians, maternal fetal medicine specialists, neonatologists and pediatric cardiologists. Fetal echocardiography is one of the most challenging and time-consuming prenatal examinations to perform, especially in multiple gestations. Performing just the basic fetal exam in twin gestations may take an hour or more. Thus, it is not practical to perform this exam in all cases of multiple gestations. Therefore our review and recommendations are related to fetal echocardiography in twin gestation.

Review Paper. Transplacental Digoxin Treatment In Prenatal Cardiac Problems In Singleton Pregnancies - Meta Analysis (Based On Literature: 1992–2015)

Abstract

Based on fourteen case reports from various centres from 1992-2015 and three original studies in 2006-2011, 122 fetuses were subjected to analysis. In these reports, transplacental digoxin treatment was administered to different cardiac anomalies such as SVT , Ebstein’s anomaly, critical AS , absent pulmonary valve syndrome, complete heart block, in foetuses with aneurysm/diverticulum of LV, in tricuspid atresia or dysplasia, rhabdomyoma, pulmonary atresia, HLHS with fibroelastosis, in TTTS and in extracardiac anomalies such as atriovenous malformation or sacrococcygeal teratoma. There was no statistical difference to suggest (Chi-square test) that digoxin was more efficient to control fetal arrhythmias than fetal congestive heart failure in nonarrhythmic patients.

Conclusions: Foetal cardiac insufficiency may appear due to different reasons (in normal heart anatomy or in heart defects, in normal sinus rhythm or due to foetal arrhythmias: tachycardias or severe bradycardia) and may be a cause of intrauterine demise. So far, we do not have strong evidence that digoxin treatment may prevent foetal death or prematurity. More research is needed to ascertain if the prolonging of pregnancy resulted from digoxin treatment or if improvement in foetal circulatory insufficiency was influenced by spontaneous regression of foetal cardiac symptoms.

What is the Survival Rate in Prenatally Detected Cantrell’s Pentalogy?

Abstract

Cantrell’s pentalogy is a congenital defect characterized by uncompleted fusion of the anterior chest wall, resulting in an extrathoracic location of the heart. Ultrasound diagnosis during the first trimester of prenatal life is possible, and termination of pregnancy is usually chosen by pregnant women. We analysed 57 fetuses: 56 from literature and one additional recent case from our institute (from 2016) to evaluate what was the survival rate reported after prenatal diagnosis, including the possibility to terminate the pregnancy, intrauterine deaths and neonatal deaths. We found 10 survivors - 18% since 1984.

Despite dismal prognosis of fetal ectopia cordis, there is a chance for postnatal survivorship probably due to evolving anatomical structures, not only in the first trimester of pregnancy but also during the following weeks of prenatal life.

Assessment of the accuracy in prenatal diagnosis of congenital malformations. Analysis of 101 questionnaires filled in by parents of neonates hospitalized in the Department of Congenital Malformations Polish Mother's Memorial Research Institute

Abstract

Introduction:

Prenatal diagnosis is an integral part of modern perinatal care. In the article results of questionnaires pertaining to the prenatal process of diagnosis are presented. Parents whose children were afflicted with congenital malformations of all types responded to enquiry

Materials and methods:

Between March 2014 and March 2015 150 of 355 infants were hospitalized in the Department of Pediatric Intensive Care and Congenital Malformations in Łódź, and 150 had congenital malformations.

Results:

101 parents of 150 children (67,3%) have given the feedback. Anomalies were such as: of the digestive system (37%), CHD (25%), OUN (14 %), genito-urinary (13%), skeletal system (9%) and respiratory system (2%). In 65 children of 101 the defects were detected prenatally. The obstetric US exam was the most frequently pointed out as performed (more than 1200). The biochemical markers and genetic tests in were performed in 34 pregnancies. The high percentage of ability to detect malformation was reported in the group of fetal echo examinations.

Conclusions:

1. Prenatal ultrasound exams were the least effective method of making appropriate prenatal diagnosis of congenital malformation.

2. Fetal echocardiography had a high level of sensitivity and specificity in detecting congenital malformations.

3. Prenatal cardiologists proved to be the most effective in detecting congenital malformations 89,3 % of detected abnormalities.

4. Biochemical exams had a positive result in only one case of Down Syndrome.

Civil Liability for Medical Malpractice. Damage Resulting from Doctor’s Negligence (Breach of Professional Duties)

Abstract

Civil liability for medical malpractice may be attributed either to a doctor or a hospital when any of these persons’ acts or omissions cause injuries to a patient; it may be also the hospital’s liability for the damage caused by negligence of its staff (doctors and other personnel). The rules that govern this liability and the way of compensating the damage are different due to the grounds on which the doctor performs medical services and, in case of hospital’s liability, the relation between a doctor and a health care institution. A doctor who runs his private medical practice bears civil liability individually and is obliged to pay damages if any of his patient suffers injury in connection with the treatment. However, a doctor who acts as employee of a health care institution is protected by the provisions of the Labour Code and exempted from civil liability to a patient. On the other hand, a so-called independent contractor’s liability is joint and several with a hospital that has engaged him. However, case law seems to protect such doctors and treat them as hospital’s employees if certain premises are fulfilled (like de facto subordination of the doctor to the head of the ward).
