Management of the pregnant woman with Marfan syndrome complicated by ascending aorta dilation

Aorta pathology and pregnancy-related risks in adult congenital cardiac disease: does the aorta dilate during pregnancy?

Background

Aortic dilatation and pregnancy are major concerns in women with aortopathy (AOP). This single-centre retrospective analysis focuses on the evolution of aortic diameters during and after pregnancy in women with Marfan syndrome (MS), Turner syndrome (TS) and bicuspid aortic valve (BAV) aortopathy.

Methods and results

Thirty-eight women who had one or more single pregnancies were included. The ascending aorta was measured during pregnancy and postpartum. During pregnancy, a significant increase of diameters of the sinus aortae (median 1.4 mm; [-1.3; 3.8]) and ascending aorta (median 2.1 mm; [0.0; 4.0]) was noted. Systemic hypertension gives dilation of the aorta, but it did not influence the overall trajectory during pregnancy.

Conclusion

Significant aortic dilatation is noted during pregnancy in women with underlying AOP, even persisting in the long term. Pre-existing systemic hypertension is associated with larger aortic diameters prior to pregnancy. More research on a larger study population however is needed.

Cardiothoracic surgery and peripheral endovascular intervention in cardiovascular damage from a cohort of orphan rheumatological diseases-epidemiological and survival analysis

Background

Aortic diseases in some orphan rheumatological diseases require medical, surgical or peripheral endovascular intervention because they can be catastrophic. Objectives: to analyze the main clinical and epidemiological characteristics of patients with Takayasu arteritis (TA), Marfan syndrome (MS) and similar conditions that were treated with cardiothoracic surgery and peripheral endovascular intervention.

Methods

Retrospective and descriptive cohort study that included patients of any age and gender with TA (as per the criteria of the American College of Rheumatology and EULAR/PRINTO), MS (according to Ghent criteria), and similar conditions who underwent cardiothoracic surgery or peripheral endovascular intervention. Data were collected from electronic charts.

Results

A total of 77 patients with TA and 135 patients with MS and similar conditions were included. The frequency of surgical or interventional requirements in patients with TA and MS/similar conditions was 77/364 (21.2%) and 135/300 (45%), respectively; such patients were followed for a median of 6 [2–12] and 3.29 (0.42–6.62) years, with (maximum follow-up range of 47 and 21.37 years, respectively). Aneurysms were present in 11 (14.3%) and 66 (48.9%) in patients with TA and MS/similar conditions, respectively. Aortic, mitral and tricuspid valve damage occurred in 8 (10.4%) patients, 4 (5.2%) patients and 1 (1.3%) patient with TA, respectively; corresponding frequencies in patients with MS/similar conditions were 98 (72.6%), 50 (37.0%) and 20 (14.8%). We identified that 20% of patients with TA died after 5.08 years (95% CI: 0.23–25.42 years) and 20 % of the patients with MS and other similar conditions died after 7.52 years (95% CI: 1.10–9.02 years).

Conclusions

The frequency of surgical intervention was low in this study. Long-term prognosis is good if surgery is performed in a timely manner. Epidemiological studies provide relevant information for public health decisions related to the management of orphan rheumatological diseases.

Aortic Dilatation in Patients With Bicuspid Aortic Valve

Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality. BAV aortic dilatation is associated with an increased risk of adverse aortic events and represents a potentially lethal disease and hence a considerable medical burden. BAV with aortic dilatation warrants frequent monitoring, and elective surgical intervention is the only effective method to prevent dissection or rupture. The predictive value of the aortic diameter is known to be limited. The aortic diameter is presently still the main reference standard for surgical intervention owing to the lack of a comprehensive understanding of BAV aortopathy progression. This article provides a brief comprehensive review of the current knowledge on BAV aortopathy regarding clinical definitions, epidemiology, natural course, and pathophysiology, as well as hemodynamic and clinically significant aspects on the basis of the limited data available.

Acute Type A Dissection during Pregnancy with Marfan's Syndrome

Background  Marfan's syndrome (MFS) is a connective tissue disorder, caused by a mutation in the FBN-1 gene and affecting multiple organ systems including the vascular system. During pregnancy, women with MFS have an increased risk of aortic dissection due to changes in the cardiovascular system.

Case Description  We present a 39-year-old woman that suffered from an acute aortic dissection in week 33 of her third pregnancy who urgently required lifesaving surgery. Three-dimensional reconstruction of computed tomography scan was performed with unborn child in utero.

Conclusion  Monitoring of patients with suspected or confirmed MFS appears essential and interdisciplinary treatment and prevention strategies are required.

Marfan Syndrome Versus Bicuspid Aortic Valve Disease: Comparative Analysis of Obstetric Outcome and Pregnancy-Associated Immediate and Long-Term Aortic Complications

Pregnancy poses a threat to women with aortopathy. Conclusive data on the obstetric and aortic outcome in this risk collective, especially when it comes to aortic complications in the long term, are still missing. This study offers a comparative analysis of pregnancy-associated outcome in 113 consecutive women with Marfan syndrome or bicuspid aortic valve disease, including 46 ever-pregnant and 37 never-pregnant women with Marfan syndrome, and 23 ever-pregnant and 7 never-pregnant females with bicuspid aortic valve disease. The overall obstetric outcome was comparable between ever-pregnant women with Marfan syndrome and with bicuspid aortic valve disease (p = 0.112). Pregnancy-associated aortic dissection occurred in two women with Marfan syndrome (3%) during a total of 62 completed pregnancies, whereas no single case of aortic event occurred in women with bicuspid aortic valve disease during a total of 36 completed pregnancies (p = 0.530). In the long-term follow-up, aortic dissection occurred in 21% of ever-pregnant women with Marfan syndrome, but in none of the women with bicuspid aortic valve disease (p = 0.022). Proximal aortic surgery was performed with similar frequency in ever-pregnant women with Marfan syndrome and with bicuspid aortic valve disease in the long term (p = 0.252). However, ever-pregnant women with Marfan syndrome were younger when surgery was performed (44 ± 9 vs. 59 ± 7 years; p = 0.041). In Marfan syndrome, long-term growth of the aorta was comparable between ever-pregnant and never-pregnant women. Pregnancy thus exhibited an increased immediate aortic risk only in women with Marfan syndrome, but not in women with bicuspid aortic valve disease. Previous pregnancy did not relate to an increased long-term risk of adverse aortic events in women with Marfan syndrome or with bicuspid aortic valve disease.

Prenatal care and labor in patients with mesenchimal dysplasias (Marfan syndrome, Ehlers-Danlos syndrome, hereditary hemorrhagic telangiectasia)

Background: Mesenchymal dysplasias or inherited connective tissue diseases are the group of diseases with deficiency of various components of connective tissue. Connective tissue disorders can affect different organs: skeleton, sight organ, skin, lungs, heart. But the most dangerous is vascular wall insufficiency leading to high risk of hemorrhage, especially during pregnancy and delivery due to hemodynamic and hormonal effects on the walls of the modified vessels.Aim: To evaluate the risk of complications during the pregnancy and delivery in patients with mesenchymal dysplasias.Study design: Fifty-six pregnancies in patients with mesenchymal dysplasias, including subclinical forms of diseases: 23 with Marfan syndrome (I group), 22 with Ehlers-Danlos syndrome (II group), and 11 with Osler-Weber-Rendu syndrome (hereditary hemorrhagic telangiectasia) (III group) of the age from 18 to 36. The study included retrospective analysis (for the period from 1993 to 2005) and prospective study. Results of study showed high risk of life-threatening complications during pregnancy and delivery, especially the risk of hemorrhage and cardiovascular complications. In all the patients, we observed the progression of bleeding or development of bleeding in new localizations (epistaxis in 27 patients, easy brushing in 22, skin and mucosa telangiectasia in 20, gastrointestinal bleedings in 4, hemoptysis in 4, hematomas for minor traumas in 14, conjunctivas hemorrhages in 5).Conclusion: The pathogenesis of bleeding in such patients has mixed pattern: besides vascular wall pathology coagulation deficiency plays some role. The preferred delivery method for such patients is caesarean section. Deep vaginal ruptures and serious hemorrhage accompany vaginal delivery.

Total artificial heart implantation in a young Marfan syndrome patient

INTRODUCTION

Cardiovascular complications represent the leading cause of morbidity and mortality in patients with Marfan syndrome. Here, we describe a unique case where a total artificial heart was implanted in a young Marfan syndrome woman.

METHODS

A 22-year-old postpartum African American female with Marfan syndrome developed multiple severe valve dysfunction and biventricular failure that was refractory to medical management. She previously had a Bentall procedure for Type A aortic dissection and repair of a Type B dissection.

RESULTS

We implanted a total artificial heart with a good outcome.

CONCLUSION

Total artificial heart is a durable option for severe biventricular failure and multiple valvular dysfunction as a bridge to transplant in a young patient with Marfan syndrome.

[Valve sparing aortic root replacement (David Procedure) in 36 year - old woman with the Marfan syndrome at the 27th week of pregnancy]

The article presents a clinical case of valve sparing aortic root replacement (David Procedure) in 36 year - old woman with the Marfan syndrome at the 27th week of gestation followed by successful prolongation of pregnancy. Indications for reconstructive intervention with cardiopulmonary bypass were: severe aortic valve insufficiency, Sinus of Valsalva Aneurysm (66 mm) and the ascending aorta dilatation (53 mm) with a rapid increase of aortic root dimension (12 mm during 9 weeks). The patient underwent a valve sparing aortic root replacement according to David procedure using Gelweave Valsalva graft (Vascutec) No 28 The time of cardiopulmonary bypass was 137 minutes; the time of aortic cross-clamping was 107 minutes. The patient was discharged from the hospital in a satisfactory condition in 21 days after the operation. Pregnancy was prolonged and ended with a planned cesarean section at 38 weeks of gestation, the birth of a boy with an Apgar score of 7/8.

[Surgical management of pregnancy-associated acute Stanford type A aortic dissection: analysis of 5 cases]

OBJECTIVE

To explore the diagnosis and treatment of pregnancy-associated acute Stanford type A aortic dissection to improve the maternal and fetal outcomes.

METHODS

We analyzed the perioperative data of 5 pregnant women with acute Stanford type A aortic dissection treated between June, 2009 and February, 2017.

RESULTS

The median age of the women was 30 years (range, 22-34 years) with gestational weeks of 23-38 weeks upon diagnosis. All the 5 patients received surgical interventions. Three patients underwent caesarean delivery and hysterectomy, and the fetuses survived after the surgery; 2 patients chose to continue pregnancy following the surgery, among whom one died due to postoperative complications and the other underwent termination of pregnancy. During follow-up, the surviving patients showed no endoleak in the descending aorta stent and the distal dissection remained stable.

CONCLUSION

The maternal and fetal outcomes of pregnancy-associated acute Stanford type A aortic dissection can be improved by multidisciplinary cooperation and optimization of the surgical approaches according to the time of pregnancy, fetal development and conditions of the aortic lesions.

Pregnancy-related acute aortic dissection in Marfan syndrome: A review of the literature

A well-established association exists between acute aortic dissection and pregnancy, particularly in women with Marfan syndrome. However, there is debate regarding appropriate management guidelines. In particular, there are differing opinions regarding when prophylactic aortic root repair should be recommended as well as the efficacy of beta blockers in this clinical scenario. The current study evaluated 10 years of published literature (2005-2015) in the PubMed/Medline database. Fifty articles, describing 72 cases of women who presented with aortic dissection in the antepartum or postpartum period were identified. Comparisons on demographic variables and clinical outcomes between cases of women with Marfan syndrome (n = 36) and without Marfan syndrome (n = 36) were conducted. There were no significant differences in demographics (age, gravidity, parity) between the Marfan and non-Marfan cases. Marfan patients presented with antepartum dissections significantly earlier in pregnancy than those without Marfan syndrome (P = .002). However, there were no significant difference between the 2 groups in maternal mortality, fetal mortality, or obstetric outcomes (mode of delivery and gestational age at delivery). Eight cases described events in Marfan women with an aortic root diameter ≤40 mm. Six events occurred in Marfan women who were managed with beta blockers. Current guidelines rely on aortic root diameter for stratification of Marfan women into risk categories, but we identified several cases that would be missed by these guidelines. Specifically, the existing literature suggest that women with Marfan syndrome should take precautions throughout pregnancy, rather than the third trimester.
