Ruptured Aortic Aneurysm in Pregnancy, Anesthetic Management of Endovascular Procedure.

ABSTRACT: Advanced pregnancy is associated with a higher risk of complicated aortopathies owing to the physiologic changes in pregnancy. The diagnosis can be elusive due to its rare incidence. The optimal treatment strategy is chosen based on the clinical condition of the patient, gestational age, and the severity of the aortic disease. A healthy young primigravida presented with acute chest pain in the early second trimester, diagnosed as a thoracic aortic aneurysm that had ruptured causing hemothorax. She underwent emergency endovascular repair under general anesthesia. Aortic disease should always be ruled out early in acute chest pain in pregnancy. Expeditious and strategic management helps improve maternal and fetal outcomes.

Transcatheter mitral valve-in-valve for pregnancy with anti-phospholipid syndrome: a case report.

BACKGROUND: Perioperative management and cardiac surgery in pregnant women with anti-phospholipid syndrome combined with heart valve disease have been rarely reported. CASE PRESENTATION: We describe a case of transcatheter mitral valve-in-valve replacement in a pregnant woman with bioprosthetic valve failure and anti-phospholipid syndrome at 18 weeks' gestation. The patient underwent a cesarean section delivery at 34 weeks of gestation, resulting in the birth of a healthy baby. CONCLUSIONS: Transapical mitral valve-in-valve surgery resulted in safe maternal and infant outcomes in a pregnant woman with anti-phospholipid syndrome combined with mitral bioprosthetic valve failure. The success of this procedure underscored the importance of multidisciplinary teamwork.

Reduction of cardiovascular complications during delivery hospitalization in patients undergoing bariatric procedures.

BACKGROUND: The global surge in obesity presents a significant health challenge, leading to increased adoption of bariatric surgery as an intervention. However, the correlation between bariatric surgery and cardiovascular outcomes during subsequent pregnancies remains unclear. The aim of our study was to determine the prevalence of cardiovascular complications during delivery hospitalizations in patients with bariatric procedure. METHODS: We performed a retrospective analysis utilizing the National Inpatient Sample database to examine data from delivery admissions of pregnant women with obesity and a history of bariatric surgery. These admissions were identified using International Classification of Diseases (ICD) codes from 2009 to 2019. In comparing pregnant individuals who had undergone bariatric surgery with those with obesity but had no such surgical history, we assessed the prevalence of cardiovascular complications. RESULTS: Our study included 3,027,987 pregnancies in individuals with obesity and an additional 117,350 pregnancies following bariatric surgery. Compared to patients without bariatric surgery, post-surgery patients were older (32.84 years vs 29.02 years), primarily White (59.0%), and mostly treated in large urban hospitals. Cardiovascular outcomes showcased reduced odds of congestive heart failure [Adjusted odds ratios (AOR) 0.11, 95% confidence intervals (CI) 0.01-0.74], gestational hypertensive complications (AOR 0.55, 95% CI 0.53-0.59), and cardiac arrhythmia (AOR 0.76, 95% CI 0.64-0.89) in the post-surgery group, with no significant difference in peripartum cardiomyopathy rates (AOR 0.72, 95% CI 0.29-1.76) and no instances of stroke or acute MI. Perinatally, the surgery cohort had higher odds of preterm birth (AOR 1.30, 95% CI 1.24-1.38) and fetal growth restriction (AOR 2.47, 95% CI 2.32-2.63) but fewer incidents of being large for gestational-age (AOR 0.35, 95% CI 0.32-0.38). As bariatric surgery became increasingly recognized as a significant factor in certain complications, its prevalence among the study population increased from 2009 to 2019. CONCLUSION: In summary, our research indicates that bariatric surgery is associated with a decreased risk of cardiovascular complications during delivery. This study highlights how insights from bariatric surgery outcomes could shape clinical guidelines for managing obesity in pregnant women.

Segmental arterial mediolysis leading to spontaneous rupture of splenic artery and fatal hemorrhage in pregnancy.

We report an unexpected death of a 22-year-old primigravida who was admitted to the hospital with sudden abdominal pain two days before a scheduled delivery. During an emergency caesarean section due to intrauterine asphyxia, intraabdominal bleeding was observed with no apparent source of bleeding. Newly formed blood clots in the subdiaphragmatic space and arterial bleeding near the splenic hilum required a surgery on the next day. Hemorrhagic shock led to multiple organ failure on the fourth day of admission. The autopsy revealed ruptured splenic artery at the pancreatic tail and near the splenic hilum. Microscopically, different stages of segmental arterial mediolysis were observed in partially thinned and aneurysmatic artery.

Aortic Dissection and COVID-19 Pneumonia in a Pregnant Woman at 34 Weeks of Gestation.

Between 0.1% and 0.3% of all aortic dissections occur during pregnancy. Arterial hypertension, connective tissue disorders, and congenital cardiovascular anomalies-including bicuspid aortic valves-are well-known risk factors. The causality between pregnancy and aortic dissection is unclear, but there have been some observations that COVID-19 illness may increase the risk. This report describes a pregnant woman at 34 weeks of gestation who had a bicuspid aortic valve and experienced an acute aortic dissection while ill with COVID-19 pneumonia. Computed tomography confirmed a type A aortic dissection and bilateral patchy pulmonary opacities. Cesarean delivery was performed, followed by replacement of the aortic valve with a mechanical aortic prosthesis and reconstruction of the ascending aorta and hemiarch. The intraoperative course was uneventful, and the patient was successfully weaned from mechanical ventilation after 51 hours. COVID-19 during pregnancy seems to increase the risk for aortic dissection, although there is no evidence base for an association. Because guidelines for diagnosis and treatment in such complex cases are lacking, care from a multidisciplinary team is crucial for successful outcomes.

Pregnancy complicated with aortic dissection: Two cases report.

RATIONALE: This study aims to investigate the characteristics of pregnancy complicated with aortic dissection (AD), diagnosis and treatment plan, and maternal and infant outcomes. PATIENT CONCERNS: Two pregnant women suffered persistent back pain were admitted to Hubei Maternal and Child Health Hospital from December 2019 to December 2020. DIAGNOSIS: Pregnant women with chest and back pain and especially hypertension should be highly suspected of AD. However, to confirm diagnosis results, laboratory tests such as D-dimer, fibrinogen and white blood cells, and even some Special examination, cardiac ultrasound, computed tomographic angiography (CTA), magnetic resonance angiography (MRA), are required. Early diagnosis and intervention can improve maternal and infant outcomes. INTERVENTIONS: Cesarean sections were performed in both patients. Case 1 underwent thoracic aortic stent implantation one day after the onset of AD symptoms. Case 2 received endovascular repair of AD 4 days after the onset of AD symptoms. OUTCOMES: In these two cases, good maternal and infant outcomes were obtained through effective early identification and treatment. LESSONS: AD is characterized with an acute onset, and the rates of misdiagnosis and missed diagnosis are high, which seriously endangers the life of mother and child. Hypertension is one of the high-risk factors causing AD. Good maternal and infant outcomes can be achieved by early identification, multidisciplinary collaboration and timely cardiac surgical intervention.

Timing of cardiac surgery during pregnancy: a patient-level meta-analysis.

AIMS: To investigate the association between the timing of cardiac surgery during pregnancy and both maternal and foetal outcomes. METHODS AND RESULTS: Studies published up to 6 February 2021 on maternal and/or foetal mortality after cardiac surgery during pregnancy that included individual patient data were identified. Maternal and foetal mortality was analysed per trimester for the total population and stratified for patients who underwent caesarean section (CS) prior to cardiac surgery (Caesarean section (CaeSe) group) vs. patients who did not (Cardiac surgery (CarSu) group). Multivariable logistic regression analysis was performed to evaluate predictors of both maternal and foetal mortality. In total, 179 studies were identified including 386 patients of which 120 underwent CS prior to cardiac surgery. Maternal mortality was 7.3% and did not differ significantly among trimesters of pregnancy (P = 0.292) nor between subgroup CaeSe and CarSu (P = 0.671). Overall foetal mortality was 26.5% and was lowest when cardiac surgery was performed during the third trimester (10.3%, P < 0.01). CS prior to surgery was significantly associated with a reduced risk of foetal mortality in a multivariable model [odds ratio 0.19, 95% confidence interval [0.06-0.56)]. Trimester was not identified as an independent predictor for foetal nor maternal mortality. CONCLUSION: Maternal mortality after cardiac surgery during pregnancy is not associated with the trimester of pregnancy. Cardiac surgery is associated with high foetal mortality but is significantly lower in women where CS is performed prior to cardiac surgery. When the foetus is viable, CS prior to cardiac surgery might be safe. When CS is not feasible, trimester stage does not seem to influence foetal mortality.

Splenic artery aneurysm rupture in pregnancy: challenges in diagnosis and the importance of multidisciplinary management.

This case of acute rupture of a splenic artery aneurysm in a patient 35 weeks pregnant demonstrates the difficulties in diagnosis and importance of multidisciplinary team management for surgical emergencies in pregnancy. A women in her early 30s presented at 35 weeks pregnant with sudden onset of severe epigastric pain and shortness of breath and was found to be tachycardic with a raised lactate. Differentials included a possible vascular event or pulmonary embolism. A CT scan demonstrated free fluid and likely ruptured splenic artery aneurysm. A rapid, thorough preoperative meeting enabled us to integrate multidisciplinary care effectively. She underwent coiling of her splenic artery, which was essential to reduce further intraoperative blood loss, followed by a midline incision for caesarean section of her baby and splenectomy. She had a long stay in the intensive care unit (ITU) and complex postoperative course but was discharged after 2 months to be reunited with her baby who was in good condition.

Antepartum acute Stanford type A aortic dissection: a case report and literature review.

BACKGROUND: Aortic dissection in pregnancy is a life-threatening event that is associated with high maternal and foetal mortality. Most cases occur during the third trimester of pregnancy, Herein, we describe a case of a pregnant woman with acute type A aortic dissection at 28 weeks of gestation. CASE PRESENTATION: A previously healthy, 24-year-old gravida 2 para 1 woman was brought to the emergency department during at the 28 weeks of gestation and diagnosed with acute type A aortic dissection. Cesarean section was performed with the cardiac surgical team on standby for cardiopulmonary bypass and the patient delivered a baby weighing 1000 g. After the operation, we performed the Beatall procedure and total arch replacement with FET using the deep hypothermic circulatory arrest technique. Both the mother and child survived and recovered well. A review of the literature on antepartum acute aortic dissection during pregnancy is also presented. CONCLUSION: Women should have a comprehensive, systematic physical examination before getting pregnant. Women at high risks of aortic dissection must undergo multidisciplinary evaluation and be counseled before pregnancy, once they become pregnant, their consistent aortic root diameter should be consistently monitored, and their blood pressure strictly controlled.

Management of mechanical aortic valve thrombosis during the first trimester of pregnancy.

BACKGROUND: Cardiovascular diseases are the leading cause of morbidity and mortality in pregnant women. On the other hand, cardiac surgery is not so common for pregnant women. CASE REPORT: We present the case of a pregnant woman with diagnosed thrombosis of the mechanical aortic valve in the 12th gestational week. The patient underwent surgery, and successfully completed her pregnancy till the 37th gestational week. CONCLUSION: We showed that, despite general anaesthesia during the first trimester of pregnancy, the application of the nonpulsatile flow of extracorporeal circulation and mild hypothermia, the operation was successfully completed and that both mother and fetus survived.

Aortic dissection in the first trimester; is it a dead end? A narrative review of recent articles.

INTRODUCTION: Acute-type aortic dissection (AD) during pregnancy is considered a rare and potentially fatal complication for both mother and fetus. Although the definite treatment for an acute-type AD is considered to be open-heart surgery, the decision to perform such a surgery during pregnancy requires a multidisciplinary approach and carries significant risks. METHODS: In the present review of the literature, we have discussed various challenges in the management of acute-type AD during pregnancy, including therapeutic approaches, choosing the preferred imaging modalities, surgical techniques, and medication challenges. We have also reported an 8-week pregnant woman with Marfan syndrome who presented with chest pain and was diagnosed with acute AD. RESULTS: The patient underwent a Bentall operation and was discharged in good condition with her fetus alive. The medical team's various decisions during preoperative, operative, and postoperative treatments were discussed. CONCLUSIONS: Type A AD is considered infrequent in the second and third trimester of pregnancy and rare in the first trimester. Performing a CMR study without contrast in stable patients can help evaluate the extension of the flap. Urgent surgery in the hands of a skilled surgeon may prove lifesaving for the mother while maximizing the likelihood of preserving the fetus.

Spontaneous Intracerebral Hemorrhage (ICH) associated with pregnancy and SARS-CoV-2 infection: a case report.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is predominately known as a respiratory disease associated with pneumonia, acute respiratory distress syndrome and multiorgan failure. However, extra-pulmonary complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly being recognized. In this regard, some studies implied the hemostatic and vascular involvements in patients with SARS-CoV-2 infection. CASE PRESENTATION: We describe a case of spontaneous Intracerebral Hemorrhage (ICH) in a pregnant patient with COVID-19 and history of cesarean section a week before the occurrence of ICH. The patient underwent emergent craniotomy with acceptable outcome. Hemorrhagic events, including ICH, may happen during COVID-19 infection with several possible mechanisms. CONCLUSION: COVID-19 patients, especially high-risk groups, are at a risk of intracranial hemorrhage. Therefore, close follow-up must be maintained and hemorrhagic events must be kept in mind in these cases.

Management of pregnancy and delivery in women with transposition of the great arteries after atrial switch operation: A 16-year single-center experience.

AIM: This study aimed to summarize cases of successful pregnancy and delivery in patients with transposition of the great arteries (TGA) after atrial switch operation (ASO), to provide management, clinical experience, and maternal and fetal outcomes. METHODS: During a 16-year period (2004-2019), we experienced 30 pregnancies in 15 patients after ASO at our institution. We retrospectively reviewed the medical records of the patients. RESULTS: In 30 pregnancies, there were 21 (70%) live births, five (17%) miscarriages, and four (13%) artificial abortions. There were no maternal or neonatal deaths. Cardiac complications occurred in nine (43%) patients: deterioration of right ventricular (RV) function in one, symptomatic heart failure (HF) in three, supraventricular tachyarrhythmia requiring electrical cardioversion in two, sick sinus syndrome that required pacemaker implantation in two, and hemoptysis in one. Obstetric complications occurred in five (24%). Neonatal complications were premature births (delivery at <37 weeks of gestation) in 15 (71%), and birthweight <2500 g in 18 (86%). The mode of delivery consisted of vaginal delivery (VD) in five (24%), and cesarean section (CS) in 16 (76%). CONCLUSION: A high incidence of preterm CS and cardiac complications including deterioration of RV function was observed in patients who had undergone ASO for TGA.

Redo surgery for a type A aortic dissection in a pregnant woman with Marfan syndrome: a complex clinical case.

Aortic dissection during pregnancy is a very rare event in the general population but can be fatal to both the mother and the fetus. A rate of dissection as high as 10% was observed in pregnant patients affected by Marfan syndrome. Facing this kind of disease can represent a challenge for the involved physicians because of its rarity. Here we present the case of an aortic dissection in a pregnant woman with Marfan syndrome who previously underwent an open heart surgery for a mitral prolapse. The diagnosis and the treatment of this case, given the mid-term gestational age combined with an increased surgical risk due to the reintervention, required a particular effort by our team. A multidisciplinary approach to the management of this patient was the key to achieve a favorable outcome both for the mother and for the baby.

A Surgical Case for Pregnancy-Related Spontaneous Coronary Artery Dissection.

The efficacy of coronary artery bypass grafting for pregnancy-related spontaneous coronary artery dissection (SCAD) is controversial, as graft occlusion due to SCAD lesion healing has been reported. Only 24 grafts in 14 cases of coronary artery bypass grafting for SCAD have been reported: 8 of the 9 arterial grafts were occluded, but 9 of the 15 vein grafts were patent. We encountered a case of coronary artery bypass grafting with left internal thoracic artery to the left antero-descending branch due to pregnancy-related SCAD. The patient's graft revealed good patency immediately postoperatively but string signs 7 months later due to healing of SCAD lesions.

Early Outcomes of Emergency Surgery for Left-Sided Mechanical Valve Thrombosis.

BACKGROUND: Valve thrombosis is a potentially lethal complication of mechanical cardiac valves. We examined the clinical characteristics as well as the early outcomes of patients undergoing emergency surgery for left-sided mechanical valve thrombosis. METHODS: Between January 2012 and May 2020, 104 consecutive patients were offered an emergency redo surgery for acute mechanical valve thrombosis. Ninety-seven of these patients were included in the current study. RESULTS: The mean age was 34.2 ± 10.3 years. Most of the patients were females (61 patients), and 27 patients (27.8%) were pregnant. The mitral valve was the site of thrombosis in 81 patients. Inadequate anticoagulation was found in 60.8% of patients. The overall early mortality was 32.9% (32 patients) with an operative mortality of 25.7%. Outcomes in the pregnant subgroup tended to be worst with a maternal mortality in the range of 37%, and with fetal and neonatal survival as low as 33.3%. CONCLUSION: The overall mortality in cases of mechanical valve thrombosis warranting surgery remains high. Since inadequate anticoagulation seems to be one of the major precipitating factors, the current study highlights the need for improvements in anticoagulation practices. The use of tissue valves should also be contemplated more seriously in some younger patients, especially females expressing the desire for future pregnancies.

Endovascular Thrombectomy for Treatment of Acute Ischemic Stroke During Pregnancy and the Early Postpartum Period.

BACKGROUND AND PURPOSE: Acute ischemic stroke (AIS) is a rare occurrence during pregnancy and the postpartum period. Existing literature evaluating endovascular mechanical thrombectomy (MT) for this patient population is limited. METHODS: The National Inpatient Sample was queried from 2012 to 2018 to identify and characterize pregnant and postpartum patients (up to 6 weeks following childbirth) with AIS treated with MT. Complications and outcomes were compared with nonpregnant female patients treated with MT and to other pregnant and postpartum patients managed medically. Complex samples regression models and propensity score matching were implemented to assess adjusted associations and to address confounding by indication, respectively. RESULTS: Among 4590 pregnant and postpartum patients with AIS, 180 (3.9%) were treated with MT, and rates of utilization increased following the MT clinical trial era (2015-2018; 1.9% versus 5.3%, P=0.011). Compared with nonpregnant patients with AIS treated with MT, they experienced lower rates of intracranial hemorrhage (11% versus 24%, P=0.069) and poor functional outcome (50% versus 72%, P=0.003) at discharge. Pregnant/postpartum status was independently associated with a lower likelihood of development of intracranial hemorrhage (adjusted odds ratio, 0.26 [95% CI, 0.09-0.70]; P=0.008) following multivariable analysis adjusting for age, illness severity, and stroke severity. Following propensity score matching, pregnant and postpartum patients treated with MT and those medically managed differed in frequency of venous thromboembolism (17% versus 0%, P=0.001) and complications related to pregnancy (44% versus 64%, P=0.034), but not in functional outcome at discharge or hospital length of stay. Pregnant and postpartum women treated with MT did not experience mortality or miscarriage during hospitalization. CONCLUSIONS: This large-scale analysis utilizing national claims data suggests that MT is a safe and efficacious therapy for AIS during pregnancy and the postpartum period. In the absence of prospective clinical trials, population-based cross-sectional analyses such as the present study provide valuable clinical insight.

Diagnosis and Treatment of Pregnancy Concurrent with Asymptomatic Aortic Dissection.

BACKGROUND: Aortic dissection (AD) refers to false lumen dissected from true lumen via the internal membrane when endovascular blood flows into the aortic wall through the cleavage, which is formed after endomembrane gape of the aortic wall. Aortic dissection is a disease of extreme danger. Pregnancy is an independent risk factor for aortic dissection. Pregnancy concurrent with aortic dissection rarely is seen, not to mention pregnancy concurrent with asymptomatic aortic dissection. CASE REPORT: We present the case of a 34-year-old female patient, who was 25+ weeks pregnant, concurrent with aortic dissection. She was accepted by our hospital and successfully treated. Retrospective analysis of clinical data was carried out in this paper by combining related literature. CONCLUSION: This disease should be correctly straightened out to prevent misdiagnosis and save the patient's life. Multidisciplinary joint decisions should be made to save lives of the patient and her fetus.

Pregnancy and delivery in a patient with a Fontan circulation and primary ciliary dyskinesia: A case report.

A patient had primary ciliary dyskinesia with a complex cardiac malformation. As a child, she had benefited from a Fontan surgery to maintain a proper cardiac function. In such patients, whether it is safe to become pregnant is controversial. This case illustrates the possibility of carrying a pregnancy to term and providing a vaginal birth if a rigorous preconception consultation is performed to ensure care by a multidisciplinary specialized team, and the patient is properly informed of the risks.
