Cruz NC, Pham E, Ali H, Nanavati J, Steppan D, Kolb TM, Thomas AJ, Murphy J, Nyhan S, Grant MC, Steppan J. How severity and classification of pulmonary hypertension affect pregnancy outcomes: a systematic review and timeline. Int J Obstet Anesth 2024; 59:104210. [PMID: 38781778 PMCID: PMC11227390 DOI: 10.1016/j.ijoa.2024.104210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 04/16/2024] [Accepted: 04/21/2024] [Indexed: 05/25/2024]
Abstract
Women with pulmonary hypertension (PH) have increased mortality during pregnancy and the peripartum period. An increasing number of publications suggest improvements in maternal outcomes, so we conducted a systematic review focusing on disease severity and maternal survival. After screening 9097 potential studies from 1967 to 2021, we identified 66 relevant publications. Outcomes improved continuously over time and mortality fell from 11.6% in studies published before 2015 to 8.2% in studies published after 2015. Mortality was lower in patients with mild disease (0.8%) than in those with Eisenmenger syndrome (26.2%) or idiopathic pulmonary arterial hypertension (7.4-24.0%). One major drawback of the published studies is that they define severity using echocardiographic-estimated pulmonary artery pressures, without considering more contemporary parameters. This systematic review provides new insights for preconception counseling on pregnancy risks related to PH and suggests that PH classification and severity should be carefully considered in determining an individual's pregnancy-associated risk.

Abstract
OBJECTIVES To determine the main clinical and demographic outcomes related to Pulmonary Hypertension (PH) and adverse obstetric and fetal/neonatal outcomes. METHODS This study retrospectively analyzed the medical record data of 154 patients with PH who were admitted to the Third Affiliated Hospital of Guangzhou Medical University between January 2011 and December 2020. RESULTS According to the severity of elevated Pulmonary Artery Systolic Pressure (PASP), 82 women (53.2%) were included in the mild PH group, 34 (22.1%) were included in the moderate PH group, and 38 (24.7%) were included in the severe PH group. There were significant differences in the incidence of heart failure, premature delivery, Very-Low-Birth-Weight (VLBW) infants, and Small-for-Gestational-Age (SGA) infants among the three PH groups (p < 0.05). Five (3.2%) women died within 7-days after delivery, 7 (4.5%) fetuses died in utero, and 3 (1.9%) neonates died. The authors found that PASP was an independent risk factor for maternal mortality. After adjustment for age, gestational weeks, systolic blood pressure, Body Mass Index (BMI), mode of delivery, and anesthesia, the risk of maternal mortality in the severe PH group was 20.21 times higher than that in the mild-moderate PH group (OR = 21.21 [95% CI 1.7∼264.17]), p < 0.05. All 131 (85.1%) patients were followed up for 12 months postpartum. CONCLUSIONS The authors found that the risk of maternal mortality in the severe PH group was significantly higher than that in the mild-moderate group, highlighting the importance of pulmonary artery pressure screening before pregnancy, early advice on contraception, and multidisciplinary care.

Abstract
Pregnancy with pulmonary hypertension (PH) seriously threatens the life and safety of mothers and infants. Here, the long-term effect of maternal PH on the postpartum growth of rat offspring was focused for the first time, as well as explored the role of Myadm in PH rats before pregnancy based upon the previous findings. Patients with PH are prone to hypoxemia, leading to insufficient placental structure and function, which affects the organ function of fetuses, followed by evidence that differently expressed genes (DEGs) existed in the heart of maternal PH newborn rats and enriched in pathways related to cardiac and nerve development on human infants with similar birth outcome: low birth weight (LBW). LBW was one of the possible birth outcomes of pregnancy with PH, especially severe PH, accompanied by evidence that offspring derived from mothers with PH presented lower birth weights and slower growth rates than those derived from normal control mothers in a rat model. Besides, maternal PH rat offspring showed cardiac remodeling and a significant elevation of the expression levels of hypoxia- and inflammation-related markers in the cerebral cortex at both 10 and 14 weeks of age, respectively. What is more, the previous studies found that the overexpression of Myadm could result in the remodeling of the pulmonary artery. And targeting Myadm to intervene PH before pregnancy could alleviate sustained low weight growth in maternal PH rat offspring, and the pathological changes of the cardiac–cerebral system caused by maternal PH, including enlarged right heart cavity, loss of cardiomyocytes, abnormal heart index, as well as cerebral cortex hypoxia and the inflammatory state as they grew up to a certain extent. The findings show the pathological significance of maternal PH on offspring growth and the cardiac–cerebral development in a rat model, as well as point out the potential treatment target, which may provide a further reference for pregnancy outcomes in women with PH and healthy development of offspring to some extent.

Acute Crit Care 2021; 36:286-293. [PMID: 34762794 PMCID: PMC8907465 DOI: 10.4266/acc.2021.00458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Accepted: 08/31/2021] [Indexed: 11/30/2022] Open
Abstract
The mortality rate of pulmonary hypertension in pregnancy is 25%–56%. Pulmonary arterial hypertension is the highest incidence among this group, especially in young women. Despite clear recommendation of pregnancy avoidance, certain groups of patients are initially diagnosed during the gestational age step into the third trimester. While the presence of right ventricular failure in early gestation is usually trivial, it can be more severe in the late trimester. Current evidence shows no consensus in the management and serious precautions for each stage of the pre-, peri- and post-partum periods of this specific group. Pulmonary hypertension-targeted drugs, mode of delivery, type of anesthesia, and some avoidances should be planned among a multidisciplinary team to enhance maternal and fetal survival opportunities. Sudden circulatory collapse from cardiac decompensation during the peri- and post-partum phases is detrimental, and mechanical support such as extracorporeal membrane oxygenation should be considered for mitigating hemodynamics and extending cardiac recovery time. Our review aims to explain the pathophysiology of pulmonary arterial hypertension and summarize the current evidence for critical management and precautions in each stage of pregnancy.

Abstract
Pregnancy entails significant changes in maternal physiology that are not well-tolerated in patients with pulmonary arterial hypertension. The profound changes in plasma volume, cardiac output, and systemic vascular resistance can lead to increased strain placed on the right ventricle, leading to right-heart failure and cardiovascular collapse. Given the complex and sometimes opposing physiologic changes, managing these patients can be challenging. As such, these patients have a significantly increased reported maternal mortality rate. This report describes a parturient with newly diagnosed severe pulmonary arterial hypertension and her anesthetic management.

Abstract
BACKGROUND Despite the development of advanced therapies for pulmonary arterial hypertension, pregnancy remains contraindicated in these patients owing to high maternal and fetal morbidity and mortality. Limited data exist regarding pregnancy management and outcome in this unique patient population. We describe a series of pregnant patients diagnosed as having pulmonary arterial hypertension before or during pregnancy who delivered at a tertiary center with a comprehensive and established pulmonary vascular disease program. OBJECTIVE This study aimed to describe a single institution's experience and review the existing literature for pregnancy management and outcomes in patients with pulmonary arterial hypertension. STUDY DESIGN A review of all patients with pulmonary arterial hypertension who were admitted for delivery between 2005 and 2019 at our institution was performed. All data were extracted from the electronic health record and included patient demographics, pulmonary arterial hypertension subtype, pulmonary arterial hypertension-targeted therapies, and mode of delivery and anesthesia. RESULTS A total of 7 patients were identified; 5 patients had a prepartum diagnosis of pulmonary arterial hypertension, whereas 2 patients were diagnosed as having pulmonary arterial hypertension during the third trimester. All patients were started on prostacyclins and the majority were on combination pulmonary arterial hypertension-targeted therapy. The maternal mortality rate was 29%. Elective cesarean delivery was performed in more than 70% of cases, whereas 1 patient required an urgent cesarean delivery and 1 patient had a successful vaginal delivery. Most patients had epidural anesthesia. Notably, 2 patients required extracorporeal membrane oxygenation after delivery and both died. There were no cases of neonatal mortality. CONCLUSION Our cases series and the published literature to date show that pregnancy in pulmonary arterial hypertension remains poorly tolerated despite marked advancements in pulmonary arterial hypertension-targeted therapies and postpartum care. A multidisciplinary team approach remains essential for the management of these patients.

Abstract
BACKGROUND The risk of complications, including death, is substantially increased in patients with pulmonary hypertension (PH) undergoing anaesthesia for surgical procedures, especially in those with pulmonary arterial hypertension (PAH) and chronic thromboembolic PH (CTEPH). Sedation also poses a risk to patients with PH. Physiological changes including tachycardia, hypotension, fluid shifts, and an increase in pulmonary vascular resistance (PH crisis) can precipitate acute right ventricular decompensation and death. METHODS A systematic literature review was performed of studies in patients with PH undergoing non-cardiac and non-obstetric surgery. The management of patients with PH requiring sedation for endoscopy was also reviewed. Using a framework of relevant clinical questions, we review the available evidence guiding operative risk, risk assessment, preoperative optimisation, and perioperative management, and identifying areas for future research. RESULTS Reported 30 day mortality after non-cardiac and non-obstetric surgery ranges between 2% and 18% in patients with PH undergoing elective procedures, and increases to 15-50% for emergency surgery, with complications and death usually relating to acute right ventricular failure. Risk factors for mortality include procedure-specific and patient-related factors, especially markers of PH severity (e.g. pulmonary haemodynamics, poor exercise performance, and right ventricular dysfunction). Most studies highlight the importance of individualised preoperative risk assessment and optimisation and advanced perioperative planning. CONCLUSIONS With an increasing number of patients requiring surgery in specialist and non-specialist PH centres, a systematic, evidence-based, multidisciplinary approach is required to minimise complications. Adequate risk stratification and a tailored-individualised perioperative plan is paramount.

Abstract
OBJECTIVES To assess pulmonary artery pressure and cardiac remodeling in pregnancy in women with pulmonary hypertension and compare these findings with studies done beyond three months postpartum. STUDY DESIGN Pregnant women with pulmonary hypertension from 2006 to 2017 were studied. Pulmonary hypertension was diagnosed when the pulmonary artery pressure exceeded 30 mmHg as estimated by right ventricular systolic pressure (RVSP) on echocardiography or 20 mmHg measured directly by mean pulmonary artery pressure (PAPm) with right-heart catheterization (RHC). Disease severity was assigned using threshold cutoffs. Indices of cardiac remodeling were compared during pregnancy after 20 weeks' gestation and again beyond three months postpartum when available. Pulmonary artery pressures obtained by echocardiography versus right-heart catheterization were also compared. RESULTS Forty-six pregnancies complicated by pulmonary hypertension in 41 women were identified. The study included 43 pregnancies that resulted in a livebirth. There were 20 women in whom studies were performed after 20 weeks' gestation and again at least 3 months postpartum or later. Pulmonary artery pressures determined during pregnancy versus beyond three months postpartum were not significantly different when measured by echocardiography (RVSP 53.5 ± 20.5 mmHg and 46.7 ± 20.4 mmHg, p = .26) in this limited cohort. In the 10 women in whom pulmonary artery pressures were measured with both echocardiography and right-heart catheterization, the former was found to significantly overestimate directly measured pulmonary artery pressure (63.3 ± 20.7 versus 37.7 ± 12.3 mmHg, p < .001). CONCLUSION Pulmonary artery pressures did not appreciably change during pregnancy after 20 weeks' gestation compared with pressures measured again beyond three months postpartum. Women with pulmonary hypertension did not show evidence of remodeling of left ventricular mass or relative wall thickness when measured in pregnancy after 20 weeks' gestation compared with beyond three months postpartum in this limited cohort. These findings suggest that cardiac remodeling in women with pulmonary hypertension is different from that of normally pregnant women and confirms the need for careful long-term follow-up.

Incidence and long-term outcomes of pregnant women complicated with pulmonary arterial hypertension during different pregnancies: A prospective cohort study from China. Int J Cardiol 2020; 326:178-183.

Abstract
BACKGROUND Pulmonary arterial hypertension(PAH) in pregnancy is a risk factor for maternal and infant death. Our study was to explore the characteristics and outcomes of pregnant women complicated with PAH during different pregnancies. METHOD Clinical data were compared among women complicated with PAH in the first and second pregnancy between 2012 and 2018. RESULTS A total of 156 patients with newly diagnosed PAH during pregnancy were enrolled. Among them, 108 (26.9 ± 3.5 years old) and 48 (30.8 ± 4.8 years old) were diagnosed PAH during their first and second pregnancy, respectively. And the incidence rates were 5.7‰ and 6.6‰ (p = 0.448). Pulmonary artery systolic pressure(sPAP)(55 ± 19 vs. 71 ± 27 mmHg, p = 0.001), NYHA functional class III-IV patients (10.2% vs. 35.4%, p < 0.001) and incidence of heart failure (5.6% vs. 18.8%, p = 0.01) were higher in the second pregnancy group than those in the first pregnancy group. Multivariate linear regression revealed that parity and time of symptom onset were independent factors of sPAP during pregnancy (p < 0.001). Multivariate logistic regression revealed that sPAP (OR = 1.045, 95% CI, 1.021-1.069) was a risk factor for perinatal heart failure, with a cut-off value of 56 mmHg (Youden index 0.586, sensitivity 93%, specificity 65%). The cumulative death rate in the subsequent 48 months (IQR: 29 to 71) were 2.8% and 10.4% (p = 0.033) in the first and second pregnancy group, respectively. CONCLUSIONS Incidence of PAH in pregnancy tends to increase with increased parity. PAH identified in during the second pregnancy were associated with more severe disease and poorer long term outcomes.

Pulmonary hypertension and pregnancy outcomes: Systematic Review and Meta-analysis. Eur J Obstet Gynecol Reprod Biol 2020; 253:108-116. [PMID: 32862030 DOI: 10.1016/j.ejogrb.2020.08.028] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 08/19/2020] [Accepted: 08/21/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVES Traditionally, pulmonary hypertension during pregnancy has been associated with increased risk of adverse maternal and fetal outcomes. The aim of this study to systematically analyze the published literature mentioning pregnancy outcomes in pregnant women with pulmonary hypertension in recent decades. STUDY METHODS A Comprehensive electronic literature search of MEDLINE, EMBASE and Cochrane library was done to find studies published in English literature from 1 Jan 1990 to 31st May 2018. Prospective and retrospective observational studies describing pregnancy outcomes in at least 4 women with pulmonary hypertension were included in this study. Meta-analysis was performed using the random-effects model. Risk of bias was assessed by the Newcastle-Ottawa Scale. The primary outcomes included maternal mortality and any pregnancy loss. The analysis included absolute risks and 95% confidence intervals (CI) for adverse outcomes using the DerSimonian-Laird random effects model. Heterogeneity was assessed by I2 statistic and visual plot. RESULTS Twenty studies captured data from 589 parturient describing 610 pregnancies. The pooled unadjusted data yielded maternal mortality of 11.5 (95% CI; 7.6-17.2) and the total pregnancy loss was 22.8 (95% CI; 16.2-31.1). Prematurity and IUGR/SGA were reported by 7 and 8 studies and had pooled estimates of 51.7 (95% CI; 37.6-65.7) and 29.3 (95% CI; 20.9-39.5), respectively. The pooled estimates of cesarean delivery and general anesthesia were 72.1 (95% CI; 60.6-81.93) and 40.1 (95% CI; 26.4-55.5), respectively. CONCLUSIONS Fetomaternal outcomes have improved in recent decades in parturient with moderate to severe pulmonary hypertension. These findings have implications for preconceptional counselling and risk stratifications.

Abstract
Despite advances in the therapy for pulmonary hypertension over the past decades, the prognosis of pregnant patients with pulmonary hypertension remains poor, with high maternal mortality. This poses a particular challenge for the mother and her medical team. In the present review, the authors have updated the classification and definition of pulmonary hypertension, summarized the current knowledge with regard to perioperative management and anesthesia considerations for these patients, and stressed the importance of a "pregnancy heart team" to improve long-term outcomes of pregnant women with pulmonary hypertension.

Endothelin receptor antagonism during preeclampsia: a matter of timing? Clin Sci (Lond) 2019; 133:1341-1352. [PMID: 31221823 DOI: 10.1042/cs20190464] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Revised: 06/06/2019] [Accepted: 06/12/2019] [Indexed: 02/07/2023]
Abstract
Preeclampsia (PE) is a pregnancy complication, featuring elevated blood pressure and proteinuria, with no appropriate treatment. Activation of the endothelin system has emerged as an important pathway in PE pathophysiology based on experimental PE models where endothelin receptor antagonists (ERAs) prevented or attenuated hypertension and proteinuria. Hence, ERAs have been suggested as potential therapy for PE. However, developmental toxicity studies in animals have shown severe teratogenic effects of ERAs, particularly craniofacial malformations. Nonetheless, sporadic cases of pregnancy in women using ERAs to treat pulmonary hypertension have been described. In this review we give an overview of cases describing ERA use in pregnancy and critically address their possible teratogenic effects. A systematic search in literature yielded 18 articles describing 39 cases with ERA exposure during human pregnancy. In most cases there was only exposure in the first trimester, but exposure later or throughout pregnancy was reported in five cases. Elective termination of pregnancy was performed in 12 pregnancies (31%), two ended in a spontaneous miscarriage (5%) and no fetal congenital abnormalities have been described in the remaining cases. These preliminary findings support the idea that ERA treatment for severe, early onset PE might be an option if applied later in pregnancy, when organogenesis is completed to avoid teratogenic risks. However, third trimester toxicology studies are warranted to evaluate drug safety. Subsequently, it remains to be established whether ERA treatment is effective for alleviating maternal symptoms, as demonstrated in preclinical PE models, allowing pregnancy prolongation without leading to adverse neonatal outcomes.

Abstract
Pregnancy is usually contraindicated in patients with pulmonary hypertension (PH). Risk factors associated with the outcome of this rare disease have not been specifically explored before.Medical records were retrospectively reviewed to identify patients with coexisting PH and pregnancy or delivery at Peking Union Medical College Hospital between January 2009 and June 2018. Demographics, characteristics of PH and pregnancy, management and outcomes were analyzed.Thirty-six pregnant women with PH were identified, including 30 cases in WHO group 1, 5 cases of group 2 and 1 case of group 4. Median pregnancy duration was 24 weeks. The overall maternal mortality rate was 8.3% (3/36), and the late fetal mortality was 31.6% (6/19). Pulmonary vascular-targeted medications were used in 17 of 26 patients with moderate or severe PH, but in none with mild PH. Maternal mortality was 2/15, 1/11, and 0 among women with severe, moderate, and mild PH, respectively. All deaths reported to be diagnosed of PH after pregnancy, and have New York Heart Association (NYHA) grades II to IV. Cesarean section was performed in 22 patients, and mortality was 3/16 among women receiving cesarean section with general anesthesia.Maternal mortality is associated with PH classification, severity of PH, delayed diagnosis of PH, and NYHA classification. Regional anesthesia seems superior to general anesthesia for cesarean section.

Han B, Xu M. A comprehensive analysis of continuous epidural analgesia's effect on labor and neonates in maternal hypertensive disorder patients. Pregnancy Hypertens 2016; 7:33-38. [PMID: 28279445 DOI: 10.1016/j.preghy.2016.12.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Revised: 12/21/2016] [Accepted: 12/22/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Maternal hypertensive disorder is one of the most common and severe medical complications during pregnancy. Epidural analgesia administration is widely used during labor process. AIM To evaluate the potential advantage or disadvantage of continuous epidural analgesia's on labor and neonates for maternal hypertensive disorder patients comprehensively. METHODS We have retrospectively analyzed 232 patients who diagnosed as maternal hypertensive disorder in our hospital since 2015. Among which, 126 patients including 28 cases of severe preeclampsia were administrated with continuous epidural analgesia (Analgesia group), the other 106 patients were untreated (Control group). We have compared the maternal age, body weight, gestational weeks, period for the first and second labor stage; the incidence of eclampsia, natural labor, cesarean section, forceps delivery and postpartum hemorrhage between these two groups respectively; furthermore, we recorded patients who received oxytocin and antihypertensive treatment during the delivery progress as well as evaluated the neonate body weight, Apgar score and performed umbilical cord blood gas analysis. RESULTS Continuous epidural analgesia does not affect the first and second labor stage period (p=0.36), However, there is a significantly higher demand for oxytocin treatment (36.5% Vs 19.8%, p<0.01) and a significantly lower requirement for antihypertensive treatment (22.2% Vs 81.1%, p<0.001) in analgesia group compared to control group. We also notice that the natural delivery ratio in analgesia group is higher than control group and most importantly, continuous epidural analgesia can increase 1min Apgar score and has no other effect on neonates' body weight, umbilical cord blood gas parameters, 5min and 10min Apgar score. CONCLUSIONS Our result based on a large cohort comprehensive analysis indicates that continuous epidural analgesia can benefit both maternal hypertensive disorder patients and neonates without any side effect.

Abstract
It is well described that patients with group 1 forms of pulmonary arterial hypertension have a high risk of mortality during pregnancy and in the early postpartum period. However, to the authors' knowledge, the diagnosis and management of group 4 pulmonary hypertension due to chronic thromboembolic pulmonary hypertension (CTEPH) during pregnancy with early postpartum pulmonary endarterectomy (PEA) has not been previously reported. We report the case of a 28-year-old woman who received a diagnosis of CTEPH during her pregnancy, was managed as an inpatient by a multidisciplinary team throughout the pregnancy and early postpartum period, and underwent PEA 6 weeks after delivery. While the management of acute pulmonary embolus in pregnancy is well described, this unique case of CTEPH diagnosed during pregnancy illustrates several challenging management issues.
