Valvular Heart Disease in Pregnancy

Valvular heart disease is a common cause of peripartum cardiovascular morbidity and mortality. The hemodynamic changes of pregnancy and their impact on preexisting valvular lesions are described in this paper. Tools for calculation of maternal and fetal risk during pregnancy are also discussed. The pathophysiology and management of valvular lesions, both obstructive and regurgitant, are then described, followed by discussion of mechanical and bioprosthetic valve complications during pregnancy.

Surgical Management of Airway Stenosis During Pregnancy: A Scoping Review

OBJECTIVE

There are several options for surgical management of subglottic stenosis, including endoscopic and open procedures. However, treatment algorithms, outcomes, and anesthetic management of subglottic stenosis during pregnancy are not well described.

DATA SOURCES

MEDLINE, EMBASE, and the Cochrane databases.

REVIEW METHODS

A scoping review of management of subglottic stenosis during pregnancy was performed, and then reported in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Inclusion criteria consisted of those with subglottic or tracheal stenosis aged greater than 18 years, those in whom management was performed during pregnancy, and those who reported delivery related outcomes.

RESULTS

After systematic review and detailed search of 330 identified articles, 15 articles met inclusion criteria and were included in the final analysis. All studies were case reports or case series (level 4 evidence). This study identified 27 patients. The median age was 29 and the median gestational age at intervention was 28 weeks. Left lateral positioning and fetal heart rate monitoring were used in nearly every case. The most common intervention performed was endoscopic balloon dilation. In many cases, jet ventilation or transnasal humidified rapid insufflation ventilatory exchange was satisfactory for maintenance of the airway. Three women ultimately required tracheostomy prior to labor and delivery. There was no fetal death or complications reported in these studies, and all but one woman proceeded to deliver at term.

CONCLUSION

Endoscopic balloon dilation during pregnancy is safe and effective, resulting in optimized respiratory outcomes for the mother and safe delivery of the fetus. The third trimester appears to be safe for airway intervention. Laryngoscope, 134:1014-1022, 2024.

Bridging gaps: The urgent call for cardio-obstetrics as a subspecialty in India

Cardiovascular disease complicates 1-4% of pregnancies. Women with heart disease going through pregnancy are on the increase. While global maternal deaths during pregnancy are decreasing, India remains a significant contributor to maternal deaths in the world. Cardiovascular disease during pregnancy is the leading cause of maternal mortality in developed nations, and this trend is expected soon in India, with the ongoing obstetric transition. Research in developed nations indicates that a high proportion of maternal mortality related to heart disease is preventable. However, India lacks indigenous data, risk stratification tools, management guidelines, and a well-defined cardio-obstetric team concept for pregnant women with heart disease. There is a pressing need to establish national registries, develop risk stratification tools, develop and disseminate management guidelines, and create dedicated cardio-obstetric programs. This article provides a comprehensive overview of this requirement and offers solutions to bridge the existing gaps in India's maternal healthcare landscape.

Treatment of Severe Symptomatic Aortic Stenosis During Pregnancy: A Potential Role for TAVR?

A 35-year-old woman presented at 22 weeks gestation with severe symptomatic aortic stenosis with a mean gradient of 94 mm Hg and an aortic valve area of 0.53 cm2. After multidisciplinary discussion, she underwent transcatheter aortic valve replacement during pregnancy.

Infective Endocarditis during Pregnancy-Keep It Safe and Simple!

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.

Reproductive Health in Congenital Heart Disease: Preconception, Pregnancy, and Postpartum

The prevalence of congenital heart disease (CHD) in pregnancy is rising due to the improved survival of patients with CHD into childbearing age. The profound physiological changes that occur during pregnancy may worsen or unmask CHD, affecting both mother and fetus. Successful management of CHD during pregnancy requires knowledge of both the physiological changes of pregnancy and the potential complications of congenital heart lesions. Care of the CHD patient should be based on a multidisciplinary team approach beginning with preconception counseling and continuing into conception, pregnancy, and postpartum periods. This review summarizes the published data, available guidelines and recommendations for the care of CHD during pregnancy.

Perioperative Anesthetic Management of the Pregnant Patient With Congenital Heart Disease Undergoing Cardiac Intervention: A Systematic Review

Maternal congenital heart disease is increasingly prevalent, and has been associated with a significantly increased risk of maternal, obstetric, and neonatal complications. For patients with CHD who require cardiac interventions during pregnancy, there is little evidence-based guidance with regard to optimal perioperative management. The periprocedural management of pregnant patients with congenital heart disease requires extensive planning and a multidisciplinary teams-based approach. Anesthesia providers must not only be facile in the management of adult congenital heart disease, but cognizant of the normal, but significant, physiologic changes of pregnancy.
