Valve Thrombosis

Abstract Background Pregnant women with mechanical valves are considered a high-risk pregnancy. They carry an increased risk of both maternal and foetal complications. This includes maternal valve thrombosis, foetal embryopathy, and haemorrhage. Cardiac surgery is generally avoided during pregnancy, and is used when there are no other alternative options. Cardiopulmonary bypass (CPB) during pregnancy is associated with high foetal mortality. Maternal mortality in the setting of CPB however, is not dissimilar to a non-pregnant woman. Case summary We present the case of a 29-year-old woman with Ebstein’s anomaly who developed thrombosis of her mechanical tricuspid valve at 4 weeks’ gestation. This was suspected to be likely due to sub-therapeutic anticoagulation at the time of presentation. She underwent a tricuspid valve replacement during the first trimester of pregnancy after failing medical therapy, with overall favourable maternal and foetal outcomes. Discussion Valve thrombosis during pregnancy is a devastating complication. There is limited data surrounding the best management strategy of valve thrombosis in pregnancy. Cardiac surgery with CPB is reserved for cases refractory to appropriate medical therapy. Though maternal mortality is largely unaffected, foetal mortality with CPB remains high. The management of pregnant women undergoing CPB is unique and extremely challenging. It requires a meticulous, multidisciplinary approach to improve overall outcomes.

Background: Cardiovascular complications that can cause severe catastrophic outcomes for both the mother and the fetus are rarely seen during pregnancy. Time to diagnosis is often delayed by a low degree of suspicion and atypical presentation. We report surgical strategies in three pregnant women with cardiovascular complications. Methods: A retrospective search from 2009 to 2016 identified three pregnant women who underwent urgent cardiac surgery. We used extracorporeal circulation (ECC) without cesarean section with careful follow-up of the fetuses during the perioperative and postoperative period. We used levosimendan as a potent inodilator in all patients to increase feto-placental blood flow and fetal heart rhythm.Results: Median time to diagnosis was 23.8 h (range 11.7-120 h) and median time from diagnosis to arrival in the operating theater was 9.8 h (range 7.4-19.8 h). One patient with prosthetic heart valve thrombosis underwent concomitant cesarean section prior to cardiac surgery. In a young pregnant woman who had spontaneous dissection of the left anterior descending artery, on-pump beating heart coronary artery bypass grafting was performed without cross clamping. Two and three months after surgery, cesarean sections were performed without any complication in two pregnant women.Conclusion: Because unusual cardiovascular complications are the main cause of maternal and/or fetus death during pregnancy, prompt and exact diagnosis is very important. Life-saving surgical strategy with the help of appropriate teams are necessary to optimize outcome for both mother and baby.

Elevated thyroid stimulating hormone (TSH) is associated with an increased risk of spontaneous abortion (SA); however, the associated mechanism remains unclear. This study aimed to investigate the expression of microRNAs (miRNAs) and pathogenesis in the chorionic villi of TSH > 2.5 mIU/L-related SA patients. The chorionic villi were collected from pregnant women in the first trimester with TSH > 2.5 mIU/L with or without SA, as well as TSH < 2.5 mIU/L with or without SA to determine the level of miRNA expression. Differentially expressed miRNAs were confirmed by qRT-PCR in a total of 92 subjects. Cell counting kit-8 (CCK8), wound healing, transwell assays, and Western blotting were used to measure cellular biological functions and related protein in HTR-8/SVneo cells. The potential mechanisms were determined using a Luciferase reporter assay and rescue experiment. Compared with normal pregnant women, miR-17-5p was decreased and zinc finger protein 367 (ZNF367) was upregulated in the chorionic villi of TSH > 2.5 mIU/L-related SA patients. Using HTR-8/SVneo cells, we demonstrated that elevated TSH inhibited miR-17-5p expression, as well as trophoblast migration and invasion. The overexpression of miR-17-5p targeted and inhibited ZNF367 expression promoting the biological function of trophoblasts. Further studies confirmed that ZNF367 interference partially reversed the biological function of the miR-17-5p inhibitor on HTR-8/SVneo cells. Taken together, our results showed that miR-17-5p promoted biological function of trophoblasts by suppressing ZNF367.

Abstract Study question Are pregnant women in the community with confirmed diagnosis of SARS-CoV–2 infection, at increased risk of an early miscarriage? Summary answer Women diagnosed with COVID–19 in their first trimester were not at increased risk of an early miscarriage. What is known already: In the earliest stages of the pandemic, the Human Fertilisation and Embryology Authority and the European Society of Human Reproduction and Embryology, independently advised against starting assisted reproductive treatments. At the time of this recommendation, among other reasons, there were concerns about the complications of SARS-CoV–2 during pregnancy and the potential for vertical transmission. We now having growing evidence that pregnant women are at an increased risk of severe illness along with higher rates of preterm births in those with severe acute respiratory syndrome. However, data on the impact of community infections of SARS-CoV–2 in early pregnancy has been sparse. Study design, size, duration This is an online survey study undertaken in the UK between May and November 2020. Pregnant women at any stage in their pregnancy were invited to participate in the study. Study participants were asked to complete online surveys at the end of each trimester. 10, 430 women were recruited to take part in the study. Participants/materials, setting, methods: We analysed pregnancy outcomes from women who were under 13 weeks gestation at the time of registration. We compared miscarriage rates among women with a confirmed diagnosis of SARS-CoV–2 infection to healthy controls. Those in the control group had not been diagnosed with or had symptoms of SARS-CoV–2 infection nor did they have any household contacts that were diagnosed with or had symptoms of SARS-CoV–2 infection. Main results and the role of chance 10, 430 pregnant women were recruited to participate in the study. 2934 were under 13 weeks gestation at the time of registration. The median age was 32.6 [IQR 29.8–35.6]. The median gestational age at registration was 8 weeks [IQR [6–10]. 246 women reported a miscarriage before 13 weeks of gestation. The overall miscarriage rate before 13 weeks of gestation was 8.4% (95% CI 7.3%–9.4%). 68 women reported a confirmed diagnosis of SARS-CoV–2 infection in their first trimester. The overall rate of confirmed SARS-CoV–2 infections in the first trimester was 2.3% (95% CI 1.8–2.9%). 3/68 (4.4%) were asymptomatic. Among those reporting symptoms, the commonest symptoms were fatigue (82%), headache (69%) and loss of smell/taste (69%). Only 38% of those with a confirmed diagnosis reported a fever. None of the 68 women with confirmed diagnosis of SARS-CoV–2 infection were hospitalised. The rate of miscarriage before 13 weeks of gestation in women who were diagnosed with SARS-CoV–2 infections was not significantly higher compared to healthy controls (11.8% versus 9.3%, p = 0.35). A further 35 women had household contacts with confirmed SARS-CoV–2 infection although they themselves had not been diagnosed. No miscarriages were reported in this group. Limitations, reasons for caution None of the 68 patients diagnosed with SARS-CoV–2 were hospitalised. We do not know whether the rate of miscarriage among hospitalised women with SARS-CoV–2 infection is the same as those with community infections. Wider implications of the findings: The overall rate of miscarriage during the pandemic was not higher than rates occurring outside of the pandemic. The rate of miscarriage among women diagnosed with SARS-CoV–2 infection was not significantly higher compared to healthy controls. This data can be used to counsel women planning a pregnancy during this pandemic Trial registration number Not applicable

Background and objective: Previous studies did not draw a definitive conclusion about the influence of the role of deep endometriosis (DE) and ovarian endometrioma (OE) as risk factor for developing adverse perinatal outcomes in patients affected by endometriosis. This study aimed to investigate if adverse fetal and maternal outcomes, and in particular the incidence of small for gestational age (SGA) infants, are different in pregnant women with OE versus pregnant women with DE without OE. Material and methods: This study was based on a retrospective analysis of a database collected prospectively. The population included in the study was divided into three groups: patients with OE, patients with DE without concomitant OE, and patients without endometriosis (controls). The controls were matched on the basis of age and parity. Demographic data at baseline and pregnancy outcomes were recorded. Results: There was no statistically significant difference in first trimester levels of PAPP-A, first and mid-pregnancy trimester mean Uterine Artery Doppler pulsatile index, estimated fetal weight centile, and SGA fetuses’ prevalence for patients with OE, and those with DE without OE in comparison to health women; moreover, there was no statistically significant difference with regard to SGA birth prevalence, prevalence of preeclampsia, and five-minute Apgar score between these three groups. Conclusions: The specific presence of OE or DE in pregnant women does not seem to be associated with an increased risk of delivering an SGA infant. These data seem to suggest that patients with endometriosis should be treated in pregnancy as the general population, thus not needing a closer monitoring.

Pregnancy is a hypercoagulable state associated with an increased risk of venous thrombosis. Calibrated automated thrombogram (CAT) is a test to monitor the thrombin generation (TG), a laboratory marker of thrombosis risk, and increases during normal pregnancy, but it is still unclear whether TG is related to the use of insulin in pregnant women with gestational diabetes mellitus (GDM). We performed thrombin generation by CAT on 135 normal pregnant women, including 43 in first trimester, 32 in second trimester, 60 in third trimester, respectively; 68 pregnant women with GDM were also enrolled, 19 patients with GDM using insulin to control blood glucose and 49 patients control their blood glucose through diet and exercise with noninsulin treatment. The overall CAT parameters were calculated using descriptive statistics method with mean ± standard deviation. Mean endogenous thrombin potential, peak thrombin generation, and StartTail time increased significantly with the pregnancy. There was no significant difference in TG test parameters except StartTail time( P = .003) in insulin-treated GDM group when compared to those without insulin in the GDM group. The normal ranges for CAT parameters in pregnant women were determined. Thrombin generation increased significantly in first trimester and remains stable in second and third trimester. The use of insulin in patient with GDM did not affect thrombin generation test. Our study helps to establish the reference range of thrombin generation in Chinese normal pregnant population and provide more basis to predict the risk of thrombus complicating during pregnancy.

Grown-up congenital heart (GUCH) is a global challenge nowadays. The strategy of medical care for GUCH women dur-ing pregnancy, childbirth and the postpartum period is a topic of active discussion in the expert community. These patients have significantly increased risk of maternal and perinatal loss. A national obstetric cardiology and cardiac surgery multi-disciplinary team (OCCS) established in academic institutions in 2013 has provided medical support to 896 GUCH pregnant women over the last 7 years. In total, GUCH patients accounted for 36% of the cohort of all the examined pregnant women. Of these, 474 (53%) were primigravid. The mean age of the patients at the time of the first visit was 27.3 ± 5.7 years. Patients with uncorrected CHD accounted for 66.2% (n = 593), and 33.8% (n = 303) of pregnant women had undergone correction, including hemodynamic correction of complex CHD in 5 patients. Risk stratification was performed using several scores (mWHO, ZAHARA, CARPREG) for the comprehensive assessment of cardiovascular risk and prediction of pregnancy, deliv-ery, and postpartum period course. 82 patients were classified as having high cardiovascular risk (CVR) after the stratifica-tion. They needed admission to the cardiac surgery facility to receive different types of medical care. There were 2 (2.4%) cases of maternal loss and 3 (3.8%) cases of adverse perinatal outcomes in this group of patients. The article presents the algorithms for multidisciplinary care strategy choice in GUCH pregnant women with high CVR and their routing principles developed by the OCCS. These algorithms significantly reduced adverse outcomes of pregnancy and childbirth in this group of patients. Long-term results were evaluated in 69 patients (86.3%). The follow-up period ranged from 1 to 91 months, on average 34.4 ± 23.6 months. There were no long-term maternal losses or repeated cardiac surgeries. There was one case of unexplained death of a child 8 months after birth. The strategy of multidisciplinary medical care of a high-class GUCH pregnant woman should be personalized depending on the clinical data and in accordance with the ESC 2018 guidelines.

The Relationship

Complex prenatal screening of the first trimester remains the most accessible and effective way of stratifying the risks of fetal chromosomal abnormalities in the general population, which has satisfactory sensitivity and specificity. Over the last decade, due to including additional parameters (average pulsation index of blood flow in the uterine arteries, average blood pressure, placental growth factor concentration, obstetric and somatic anamnesis data), it has also become a tool for determining obstetric risks. The objective: to study the effect of these additional parameters on the accuracy of predicting the most common aneuploidies was made. Materials and methods. The cohort included 2164 pregnant women at 11+0 – 13+6 weeks of gestation, who underwent extended complex screening of the first trimester, which aimed to determine the risk of trisomy on the 21st, 13th and 18th chromosomes in the fetus and calculation risk of perinatal complications, namely: premature birth, preeclampsia and fetal growth retardation. Results. It was found that the history of miscarriage at 13–22 weeks of pregnancy (P=0,0006), increased resistance in the uterine arteries (P=0,0307), decreased concentration of placental growth factor (P=<0,0001) and increased mean blood pressure (P=0,0125) correlate with a high risk of trisomy of chromosome 21. Type I diabetes mellitus in pregnant women (P=0,0477) correlates with an increased risk of trisomy on chromosome 18. The concentration of placental growth factor (P=<0,0001) correlates with an increased risk of trisomy on chromosome 13. Conclusions. The data obtained require detailed analysis in the context of the possibility of optimizing mathematical models for predicting aneuploidy, as well as studying the relationship between markers of trophoblast invasion and chromosomal pathology of the fetus to better understand the mechanisms of first trimester fetal loss and placental dysfunction in the second half of pregnancy.

Aim: to assess the prevalence of V617F somatic mutation of the JAK2 gene in pregnant women.Materials and methods. This non-interventional study was performed in the framework of routine clinical practice and included 1532 samples of venous blood from pregnant women who applied for medical assistance at Krasnoyarsk Regional Clinical Center for Maternal and Child Welfare. We used blood samples left after all routine laboratory tests had been done. These leftovers were pooled in the way that ensured an equal ratio of nucleated cells. Each pool contained 7 separate blood samples. The unused samples that remained after the pooling were frozen and stored at –20°C until the end of entire testing procedure. The V617F JAK2 mutation was detected by the real-time allele-specific polymerase chain reaction test.Results. Among the examined pregnant women, 6 (0.4 %) were identified as carriers of V617F JAK2 mutation. Three women with this mutation suffered from infertility for 4, 5, and 10 years; two of them had repeated miscarriages in the first trimester of pregnancy. The 6 women – carriers of this mutations had no concomitant genetic polymorphisms typical of thrombophilia (factors FII, FV), and no abnormal coagulation characteristics. Analysis of their medical records showed that in the past, two of these women had gestational hypertension, one developed a clinical picture of preeclampsia, and another one (with the maximum presence of the mutant allele) had a history of acute lymphoblastic leukemia followed by stable remission.Conclusion. The routine laboratory detection of the V617F JAK2 mutation can facilitate timely identification of the increased risk of pregnancy pathology, as well as timely diagnosis of hematological cancer.
