Abstract
The obesity epidemic is growing and poses significant risks to pregnancy. Metabolic impairment can be associated with short- and long-term maternal and perinatal morbidity and mortality. The cardiovascular implications are known in those with metabolic disorder outside of pregnancy; however, little is known of the cardiac function in pregnancies complicated by obesity. Maternal cardiac adaptation plays a vital role in normal pregnancy and is known to be involved in the pathophysiology of adverse pregnancy outcomes. Bariatric surgery is the most successful treatment for sustainable weight loss and pre-pregnancy bariatric surgery can drastically change the maternal metabolic profile and pregnancy outcomes. In this review, we discuss the available evidence on maternal cardiac function in pregnancies affected by obesity and its associated consequences of gestational diabetes and hypertension (chronic and hypertensive disorders in pregnancy), as well as pregnancies following bariatric surgery.

Khoromi S. Secondary headaches in pregnancy and the puerperium. Front Neurol 2023; 14:1239078.

Abstract
Headache during pregnancy can be due to primary causes such as migraine but can also be a presenting symptom of secondary causes including life threatening conditions. This is a minireview of secondary causes of headache during pregnancy and the puerperium. Unique alterations in physiological and vascular functions as well as in the coagulation pathway which occur during pregnancy increase the risk of most of these secondary conditions which include preeclampsia, eclampsia, hemorrhagic stroke, cerebral venous, sinus thrombosis, reversible cerebral vascular syndrome, and posterior reversible encephalopathy. Marked increase in progesterone level in pregnancy is also associated with the growth of tumors such as meningiomas, as 70% of these tumors are positive for progesterone receptors and increase in size can lead to headache along with other neurological symptoms. Hemodynamic changes can lead to the growth of meningiomas as well. Although hormone producing pituitary tumors are usually not conducing to pregnancy, women with known pituitary tumors who do get pregnant may become symptomatic during pregnancy and develop secondary headache. Another rare cause of secondary headache during pregnancy is pituitary apoplexy. Although its occurrence is uncommon, it needs to be properly recognized and treated to avoid endocrine and visual complications. Other rare entities with increased incidence during the puerperium such postdural puncture headache will be also discussed. In summary, new onset headache during pregnancy deserves special attention because in the absence of proper recognition and treatment, secondary headache disorders can endanger the life of the mother and the fetus.

Abstract
The diagnosis of infective endocarditis (IE) during pregnancy is accompanied by a poor prognosis for both mother and fetus in the absence of prompt management by multidisciplinary teams. We searched the electronic databases of PubMed, MEDLINE and EMBASE for clinical studies addressing the management of infective endocarditis during pregnancy, with the aim of realizing a literature review ranging from risk factors to diagnostic investigations to optimal therapeutic management for mother and fetus alike. The presence of previous cardiovascular pathologies such as rheumatic heart disease, congenital heart disease, prosthetic valves, hemodialysis, intravenous catheters or immunosuppression are the main risk factors predisposing patients to IE during pregnancy. The identification of modern risk factors such as intracardiac devices and intravenous drug administration as well as genetic diagnostic methods such as cell-free deoxyribonucleic acid (DNA) next-generation sequencing require that these cases be addressed in multidisciplinary teams. Guiding treatment to eradicate infection and protect the fetus simultaneously creates challenges for cardiologists and gynecologists alike.

Abstract
OBJECTIVES The aim of this study was to assess the characteristics of mitral annular plane systolic excursion (MAPSE) in different longitudinal directions in normal fetuses using a new method, automatic cardiac motion quantification (aCMQ). METHODS A cross-sectional study was conducted in 164 fetuses with structurally normal hearts. The time-displacement curves of the septal mitral annulus (SMA) in three directions, including point A, B and C (MAPSE-SMA-A, MAPSE-SMA-B, MAPSE-SMA-C), were recorded by aCMQ. The time to peak (TTP) in three directions, including point A, B and C (TTP-SMA-A, TTP-SMA-B, TTP-SMA-C) were recorded. In the same way, various parameters of the lateral mitral annulus (LMA) were obtained including MAPSE-LMA-A, MAPSE-LMA-B, MAPSE-LMA-C, TTP-LMA-A, TTP-LMA-B and TTP-LMA-C. Free angle M-mode echocardiography (FAM) was used to obtain MAPSE of LMA (FAM-MAPSE). Finally, all the data were analyzed statistically. RESULTS MAPSE was positively correlated with gestational age, and the difference between the second- and third-trimester groups was statistically significant. MAPSE-LMA in point B and C were greater than those of SMA. MAPSE-LMA-C and MAPSE-SMA-A were the largest in three directions.The difference between point B and C were statistically significant (p < .05), with no significant difference at point A (p > .05). There was no significant difference found in all TTP (all p > .05). The MAPSE-LMA-C was less than the FAM-MAPSE, and the differences were found significantly (p < .05), but there was better correlation (p < .05). CONCLUSIONS The longitudinal movement of the fetal mitral annulus is comprehensive, with multiple directions and different displacements. Perpendicular to the mitral annulus is the maximum displacement. It is positively related to the gestational age. From the second trimester, the longitudinal contraction of the left ventricle wall has good synchronization. It possesses clinical value in selecting different methods and parameters during evaluating left ventricular function.

Abstract
Abstract
Purpose
To evaluate the relationship between maternal left ventricular systolic function, utero-placental circulation, and risk of adverse neonatal outcomes in women with cardiac disease.
Methods
119 women managed in the pregnancy heart clinic (2019–2021) were identified. Women were classified by their primary cardiac condition. Adverse neonatal outcomes were: low birth weight (< 2500 g), small-for-gestational-age (< 10th birth-weight centile), pre-term delivery (< 37 weeks’ gestation), and fetal demise (> 20 weeks’ gestation). Parameters of left ventricular systolic function (global longitudinal strain, radial strain, ejection fraction, average S’, and cardiac output) were calculated and pulsatility index was recorded from last growth scan.
Results
Adverse neonatal outcomes occurred in 28 neonates (24%); most frequently in valvular heart disease (n = 8) and cardiomyopathy (n = 7). Small-for-gestational-age neonates were most common in women with cardiomyopathy (p = 0.016). Early pregnancy average S’ (p = 0.03), late pregnancy average S’ (p = 0.02), and late pregnancy cardiac output (p = 0.008) were significantly lower in women with adverse neonatal outcomes than in those with healthy neonates. There was a significant association between neonatal birth-weight centile and global longitudinal strain (p = 0.04) and cardiac output (p = 0.0002) in late pregnancy. Pulsatility index was highest in women with cardiomyopathy (p = 0.007), and correlated with average S’ (p < 0.0001) and global longitudinal strain (p = 0.03) in late pregnancy.
Conclusion
Women with cardiac disease may not tolerate cardiovascular adaptations required during pregnancy to support fetal growth. Adverse neonatal outcomes were associated with reduced left ventricular systolic function and higher pulsatility index. The association between impaired systolic function and reduced fetal growth is supported by insufficient utero-placental circulation.

Abstract
AIMS Left ventricular (LV) contractility during noncomplicated pregnancy has been previously investigated by two-dimensional speckle-tracking echocardiography (2D-STE), with conflicting results. Chest abnormalities might affect myocardial strain parameters, yet this issue has not been previously investigated during pregnancy. We evaluated the influence of chest conformation on myocardial strain parameters in healthy pregnant women. METHODS Between October 2019 and February 2020, 50 healthy pregnant women (32.3 ± 4.0 years old) were consecutively studied. They underwent obstetric visit, assessment of chest shape by modified Haller index (MHI; chest transverse diameter over the distance between sternum and spine) and transthoracic echocardiography implemented with 2D-STE analysis of all myocardial strain parameters in the first trimester (12-14 weeks), third trimester (36-38 weeks) and 6-9 weeks after delivery. RESULTS LV ejection fraction remained substantially unchanged (P = 0.13), while on the average all myocardial strain parameters showed a small but significant decrease during pregnancy, and recovered postpartum (all P < 0.001). Women with concave-shaped chest wall (MHI > 2.5, n = 29), and those with normal chest conformation (MHI ≤ 2.5, n = 21) were then separately analyzed. Pregnant women with MHI above 2.5, but not those with MHI 2.5 or less, showed a progressive but reversible decrease in all myocardial strain parameters (all P < 0.001). MHI was strongly correlated with LV global longitudinal strain (r = -0.87) and LV global circumferential strain (r = -0.83) in the third trimester of pregnancy. CONCLUSION Myocardial strain impairment during healthy pregnancy may not reflect intrinsic myocardial dysfunction but rather intraventricular dyssynchrony related to a narrow antero-posterior chest diameter and rise in the diaphragm, with consequent extrinsic myocardial compression.

Abstract
Profound physiological changes in the maternal cardiovascular system occur shortly after conception. These changes may impact upon the investigation of healthy and complicated pregnancies. Additionally, concerns regarding fetal exposure to ionising radiation are important considerations in maternal testing. This manuscript reviews the important physiological changes pertinent to the investigation of maternal cardiovascular disease in pregnancy.

Abstract
AIM To evaluate the long-term prognostic significance of right ventricular (RV) deformation and RV-arterial coupling in a cohort of patients with heart failure (HF) due to severe aortic stenosis (AS) candidate for trans-catheter aortic valve implantation (TAVI). METHODS The study is a retrospective analysis of 56 patients undergoing echocardiography before TAVI execution. RV function was defined by tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), peak systolic myocardial velocity by tissue Doppler imaging (RVSm) and RV longitudinal strain (RVLS). RV-arterial coupling were defined as TAPSE and RVLS normalized for systolic pulmonary artery pressure (sPAP) to obtain afterload-independent parameters: TAPSE/sPAP and RVLS/sPAP, respectively. All-cause mortality was the primary endpoint of survival analysis; composite of death and hospitalization for HF was the secondary endpoint. RESULTS All patients underwent TAVI from femoral access. Mean age was 81.6±6.3 years and left ventricular ejection fraction was preserved in most patients (51±15%). At 10 years, using Cox regression analysis adjusted for the parameters related to prognosis at univariate analysis, we found that only pre-procedural RVLS was independently associated with all-cause mortality (aHR 1.53, 95% CI 1.10-2.12, P=0.011). RVLS (aHR 7.542, 95% CI 1.325-42.921, P=0.023), sPAP (aHR 1.421, 95% CI 1.045-1.932, P=0.025), TAPSE/sPAP (aHR 4.977, 95% CI 5.425-21.99, P=0.044) and RVLS/sPAP (aHR 2.333, 95% CI 3.9677-12.999, P=0.046) were independently associated with the secondary endpoint. CONCLUSIONS Among patients with HF due to severe AS undergoing TAVI, deformation imaging (i.e., RVLS) and RV-arterial coupling (i.e., TAPSE/sPAP and RVLS/sPAP) provide better risk stratification at long-term follow up of 10 years than other RV echocardiographic parameters.

Abstract
Cardiovascular magnetic resonance based tissue tracking (CMR-TT) was reported to provide detailed insight into left ventricular mechanical features. However, inadequate knowledge of the right ventricle (RV) mechanical deformation has been acquired by this advanced technique so far. It was the aim of this study to establish reference values of RV free wall (RVFW) global, regional and segmental longitudinal peak strain and strain rate (LS and LSR), and to investigate the gender- and age-related difference as well as the base-to-apex gradient of RVFW-LS and LSR with CMR-TT. 150 healthy volunteers (75 males/females) were retrospectively and continuously recruited and subdivided into three age groups (G20–40, G41–60 and G61–80). RVFW global, regional (basal, middle-cavity and apical) and segmental LS (GLS, RLS, SLS) along with systolic and diastolic LSR were generated by post-hoc CMR-TT analysis of standard steady-state free precession long-axis four-chamber view cine images acquired at 1.5T field strength. The reference value of myocardial RVFW-GLS was − 24.9 ± 5.2%. We found that females showed more negative GLS than males except in the youngest group, and no age-related difference of GLS was observed in both gender groups. RLS and SLS presented with the same age-related tendency as GLS. The basal and middle-cavity LS were similar between each other and significantly larger than apical LS. RVFW-GLSR resulted as − 1.73 ± 0.58 s−1 and 1.69 ± 0.65 s−1 during systolic and diastolic phases, respectively. The diastolic GLSR of males tended to decline with the ageing and was significantly lower than that of females in G61–80 group. Regional and segmental LSR showed significant gender-related differences in certain basal and apical region/segments without any age-related effects. CMR-TT overcomes the difficulty in measuring RV global and segmental deformation. The establishment of the vendor-, gender- and segment-specific reference values of RVFW-LS and LSR is essential for the rapid and efficient utilization of CMR-TT modality in the clinical routine.
