Objective: Pregnancy causes physiological, hormonal, and hemodynamic changes that affect the aortic wall dimensions and elastic properties. Multiple pregnancies increase the risk of aortic enlargement and reduce aortic elasticity. The aortic stiffness index (ASI) and aortic velocity propagation (AVP) are markers of elasticity. Additionally, epicardial fat thickness (EFT) is associated with cardiovascular risk factors. The impact of multiparity on ASI, AVP, and EFT has not been previously reported in the literature. Therefore, we aimed to investigate the association of these parameters with the number of live pregnancies in this study.

Methods: A total of 410 patients were enrolled in this prospective study. Patients were divided into three groups based on the number of live births: Group 1 (n = 0, 128 patients), Group 2 (4 ≥ n > 0, 157 patients), and Group 3 (n ≥ 5, 125 patients). A linear regression analysis was conducted to investigate trend associations of ASI, AVP, and EFT between the study groups. Multiple linear regression analysis was used to evaluate the independent predictors of continuous parameters.

Results: There were increasing trends in multiparity with variables such as aortic systolic (ASD) and diastolic diameters, pulmonary artery diameters, ASI, and EFT, and a decreasing trend in AVP. The number of pregnancies was strongly and positively correlated with ASI, moderately and positively correlated with EFT and ASD, and moderately and negatively correlated with AVP.

Conclusion: Multiparity was independently associated with ASI, EFT, ASD, and AVP, reflecting decreased elasticity and elevated cardiovascular risk in multiparous women.

Objective: Peripartum Cardiomyopathy (PPCM) is a life-threatening, rare disorder that occurs during the late stages of pregnancy or the early postpartum period. The ARTEMIS (A RegisTry of pEripartuM cardIomyopathy in Turkish patientS) aims to investigate the clinical characteristics and outcomes of PPCM in Türkiye, providing insights into its management within this specific population.

Methods: The ARTEMIS registry retrospectively enrolled patients diagnosed with PPCM within the last five years at 44 cardiology centers across Türkiye. Eligible participants were women over 18 years old, diagnosed with PPCM and without other known cardiac pathology. Data collected included demographic information, clinical presentation, diagnostic modalities, treatment regimens, and outcomes.

Results: The study included 293 patients, predominantly between 25 and 35 years old. The majority presented with symptoms such as dyspnea and palpitations, diagnosed postpartum via echocardiography. A low use of advanced diagnostic imaging was noted, relying primarily on echocardiography for evaluation. Common treatments included beta blockers (97.8%), angiotensin-converting enzyme (ACE) inhibitors (71.3%), and in severe cases, bromocriptine (6.9%). The study highlighted a mortality rate of 5.1%, with surviving patients often requiring continued management for heart failure. Diagnostic challenges and variations in treatment responses were noted, reflecting the complexity of PPCM diagnosis and care.

Conclusion: The ARTEMIS registry provides valuable insights into the management of PPCM in Türkiye, highlighting the need for targeted educational programs for healthcare providers and patients. It also underscores the importance of national registries in understanding and improving outcomes for rare diseases like PPCM.

Objective: Pregnancy in women with Eisenmenger syndrome (ES) presents very high morbidity and mortality rates for both the mother and fetus. In this study, we aimed to evaluate the outcomes of pregnancies affected by ES.

Methods: This retrospective cohort study reviewed pregnancies in women with ES at two university hospitals over the past 10 years. The primary outcomes examined were maternal, perinatal, and pregnancy-related outcomes in women with ES.

Results: The study enrolled eight pregnant women diagnosed with ES. The average maternal age was 26.7 years (range 21-36 years). The causes of ES included ventricular septal defect (five patients), patent ductus arteriosus (two patients), and atrial septal defect (one patient). Four patients had been diagnosed with ES before pregnancy. Two patients died in this group; one developed right heart failure in the third trimester and unfortunately died immediately after delivery due to cardiogenic shock, and another died on the 10th postpartum day from sudden cardiac arrest despite having had a successful delivery. Four patients were diagnosed with ES during the postpartum period; none in this group died, and there were no cases of fetal mortality. We could not identify any clinical or echocardiographic predictors for postpartum mortality. The two deceased patients showed tendencies of severe right heart failure and lower oxygen saturation during the third trimester and before delivery.

Conclusion: Despite advanced obstetric care and targeted treatments for pulmonary arterial hypertension, maternal mortality is still unacceptably high in patients with ES. No significant predictors of maternal mortality were identified.

Objective: Gestational hypetension is a major public health concern due to its links with cardiovascular disease, stroke and neonatal morbidity and mortality. Timely diagnosis and effective management of gestational hypertension are essential for both maternal and neonatal health. Neuropeptide FF Receptor 2 (NPFFR2) is a protein secreted by the brain and placenta, involved in pain regulation, water balance, and the modulation of cardiovascular effects. This study aims to conduct a comparative analysis of NPFFR2, smoothelin (SMTH), echocardiographic results and pregnancy outcomes in pregnant women with and without gestational hypertension.

Method: This study included 78 pregnant participants, which were grouped into women with gestational hypertension (n = 39) and those without gestational hypetension (n = 39). The gestational hypertension population was classified into two groups, i.e., dipper and non-dipper groups, based on the 24-hour ambulatory blood pressure monitoring results. Smoothelin and NPFFR2 analyses were performed using the blood samples and placental tissue samples collected from all participants, along with echocardiography and 24-hour ambulatory blood pressure monitoring.

Results: The study group comprised 78 pregnant women with a mean age of 28.8 years and mean gestational age of 27.7 weeks. The gestational hypertension group had a significantly higher NPFFR2 levels, lower SMTH levels and gestational age at birth and higher all 24-hour ambulatory blood pressure monitoring findings. The left atrial-to-aortic ratio and Tricuspid annular plane systolic excursion (TAPSE) were significantly higher in GİH group than in the control group. NPFFR2 and gestational age at birth were found to be independently associated with neonatal intensive care unit admission.

Conclusion: Serum NPFFR2 levels were increased in women with gestational hypertension, SMTH levels were decreased, and pregnancy prognosis was found to be associated with NPFFR2 levels.

Objective: Gestational diabetes mellitus (GDM) is a common condition that occurs during pregnancy and results in cesarean section, pre-eclampsia, and neonatal morbidity. Angiotensin II is a potent vasoconstrictor and an important determinant of uteroplacental perfusion. Toll-like receptor 4 (TLR4) was found to contribute to diabetes progression. This study aimed to determine how TLR4 activation affects the contraction mediated by angiotensin II type 1 receptor in the isolated umbilical arteries of normal and GDM women.

Methods: Angiotensin II was applied with either a TLR4 agonist or TLR4 antagonists to isolated arteries from normal and GDM umbilical cords. The changes in the angiotensin II response were expressed as the maximal contraction percentage and pD2 values. The mRNA expression levels of TLR4 and angiotensin II type 1 receptor gene were measured via quantitative  real-time polymerase chain reaction analysis.

Results: This study displayed an increased sensitivity to angiotensin II in the arteries of the GDM group compared with the normal group. The TLR4 agonist showed a synergistic effect with angiotensin II, while the TLR4 antagonists were not strongly determinant. In the GDM group, the TLR4 mRNA level is slightly higher than in the normal pregnancy group; however, no statistical difference was noted.

Conclusion: Toll-like receptor 4 may determine the vasoconstrictive effect of angiotensin II in normal and GDM umbilical arteries. Some studies showed a similar interaction as supportive. However, comprehensive animal and/or human studies are promising.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases. In this review, we aimed to evaluate the role of multimodality imaging in diagnosis of cardiomyopathies with key images and discussed the effects of genetics on the diagnostic, prognostic, and therapeutic guidance of cardiomyopathies.

The most common cyanotic congenital heart disease (CHD) in adults is Tetralogy of Fallot (TOF), accounting for 10% of congenital heart anomalies and 75% of cyanotic CHD cases. It is a congenital heart disease that most often requires surgical correction within the first year of life. Corrective surgical treatment for TOF began in the 20th century, starting with a temporary shunt procedure and advancing to primary surgical repair. The current approach in infants often involves valve-sparing techniques. Following corrective surgery, more than 85% of patients with TOF can survive into adulthood. Without repair, however, patients with TOF rarely reach adulthood, and the prognosis for pregnant women with CHD is poor. Congenital heart disease is one of the leading causes of indirect maternal deaths. The literature indicates that pregnant patients with corrected TOF still face a higher risk compared to otherwise healthy women. According to the modified World Health Organization maternal cardiovascular risk classification, patients with repaired TOF have a mild risk of mortality and a moderate risk of morbidity, with the risk of maternal cardiac events ranging from 5.7% to 10.5%. Cardiac evaluations should be performed at least once during each trimester of pregnancy. In this case report, we discuss the pregnancy and successful, uncomplicated birth of a woman with TOF who underwent corrective surgery in childhood.
