Anesthetic Treatment of Cardiac Disease During Pregnancy

Anaesthetic Management and Peripartum Outcomes for Parturients With Valvular Heart Disease in a Tertiary Care Hospital of Pakistan

Introduction Parturients with valvular heart disease are at increased risk of maternal cardiac and neonatal complications. We aim to observe maternal cardiac complications in relation to the type of anaesthesia and mode of delivery as our primary objective and neonatal complications as the secondary outcomes. Methods We retrospectively reviewed all parturients with valvular heart disease undergoing delivery over a five-year period at the Aga Khan University Hospital, Karachi, Pakistan. to identify maternal cardiac and neonatal complications occurring during the peripartum period. Results Of 83 patients with valvular heart disease, 79.5% had rheumatic heart disease. Caesarian section (CS) was performed in 79.5% of patients and regional anaesthesia (RA) was given to 62.1%. Patients with cardiac risk index > 2 were delivered by CS and 64.5% received RA. One maternal and three neonatal deaths were reported with a complication event rate of 9.64% in parturients and 40.9% in neonates. Incidence of maternal cardiac events was one in 17 (5.8%) for vaginal deliveries versus seven in 66 (10.6 %) for CS. Maternal events for CS under RA was 5/66 (7.5 %) vs 2/66 (3%) under general anaesthesia. The incidence of peripartum maternal cardiac events when stratified by severity of cardiac disease was similar to a previously derived cardiac risk index for pregnant women with cardiac disease with no statistical difference in the adverse events rate from the estimated rates (p-value= 0.42). Conclusion Elective CS with RA was a common approach for high-risk parturients; however, the benefits cannot be ascertained. Despite low maternal and neonatal mortality, significant maternal cardiac and neonatal complications were observed.

Peripartum Cardiomyopathy: Current Understanding of Pathophysiology, Diagnostic Workup, Management, and Outcomes

Peripartum cardiomyopathy (PPCM) is a relatively rare, potentially life-threatening, idiopathic form of cardiomyopathy that affects previously healthy young women during late pregnancy or in the early postpartum period and is characterized by left ventricular (LV) systolic dysfunction in the absence of any other identifiable cardiac causes. Morbidity and mortality with PPCM are remarkably high and it continues to be one of the leading causes of maternal death. Although remarkable advances have been made in our understanding of PPCM in the last few decades, unanswered questions remain regarding its pathophysiology, diagnostic workup, and management options. In this article, we will complete an updated, comprehensive review of PPCM, including the epidemiology and risk factors, proposed etiology, presentation and complications, management, prognostic indicators and outcomes. In addition, we will identify current challenges and gaps in knowledge.

Management of acute cardiovascular complications in pregnancy

The growing population of women with heart disease of reproductive age has been associated with an increasing number of high-risk pregnancies. Pregnant women with heart disease are a very heterogeneous population, with different risks for maternal cardiovascular, obstetric, and foetal complications. Adverse cardiovascular events during pregnancy pose significant clinical challenges, with uncertainties regarding diagnostic and therapeutic approaches potentially compromising maternal and foetal health. This review summarizes best practice for the treatment of common cardiovascular complications during pregnancy, based on expert opinion, current guidelines, and available evidence. Topics covered include heart failure (HF), arrhythmias, coronary artery disease, aortic and thromboembolic events, and the management of mechanical heart valves during pregnancy. Cardiovascular pathology is the leading cause of non-obstetric morbidity and mortality during pregnancy in developed countries. For women with pre-existing cardiac conditions, preconception counselling and structured follow-up during pregnancy are important measures for reducing the risk of acute cardiovascular complications during gestation and at the time of delivery. However, many women do not receive pre-pregnancy counselling often due to gaps in what should be lifelong care, and physicians are increasingly encountering pregnant women who present acutely with cardiac complications, including HF, arrhythmias, aortic events, coronary syndromes, and bleeding or thrombotic events. This review provides a summary of recommendations on the management of acute cardiovascular complication during pregnancy, based on available literature and expert opinion. This article covers the diagnosis, risk stratification, and therapy and is organized according to the clinical presentation and the type of complication, providing a reference for the practicing cardiologist, obstetrician, and acute medicine specialist, while highlighting areas of need and potential future research.
