Cardiovascular Disease Screening in Pregnancy

Bicoastal Spontaneous Coronary Artery Dissection: A Therapeutic Dilemma

Due to the potential for severe maternal morbidity and even mortality, pregnancy-associated spontaneous coronary artery dissection (P-SCAD) often presents as a clinical conundrum. While current recommendations encourage coronary interventions when medically indicated even during pregnancy, the hesitation still understandably exists. Meanwhile, given the rarity of the condition, the guidelines for management are still based on expert consensus. We present a case of P-SCAD in a 38-year-old woman with initial presentation at 28 weeks' gestation and recurrence at 9 days postpartum. A unique complication of this case is its transcontinental nature: the initial event occurred while the patient was on vacation across the country from her home. Questions arose not only with regard to her immediate management and care but also when she would be able to travel and how her complex care would be continued cross-country. This case raised important questions regarding the antepartum management of acute coronary syndrome (ACS). It also highlights the importance of multidisciplinary care, especially with a cardio-obstetrics team, in the management of P-SCAD and emphasizes the role for universal screening for cardiac diseases in pregnancy.

Pregnancy-related maternal deaths due to cardiovascular diseases in Japan from 2010 to 2019: an analysis of maternal death exploratory committee data

OBJECTIVE

Cardiovascular disease (CVD) is the leading cause of maternal deaths in high-income countries. This study aimed to assess the characteristics of maternal deaths due to CVDs and the quality of care provided to patients, and to identify elements to improve maternal care in Japan.

METHODS

This descriptive study used the maternal death registration data of the Maternal Deaths Exploratory Committee of Japan between 2010 and 2019.

RESULTS

Of 445 eligible pregnancy-related maternal deaths, 44 (9.9%) were attributed to CVD. The most frequent cause was aortic dissection (18 patients, 40.9%), followed by peripartum cardiomyopathy (8 patients, 18.2%), and pulmonary hypertension (5 patients, 11.4%). In 31.8% of cases, cardiopulmonary arrest occurred within 30 min after initial symptoms. Frequent symptoms included pain (27.3%) and respiratory symptoms (27.3%), with 61.4% having initial symptoms during the prenatal period. 63.6% of the patients had known risk factors, with age ≥35 years (38.6％), hypertensive disorder (15.9%), and obesity (15.9%) being the most common. Quality of care was assessed as suboptimal in 16 (36.4%) patients. Cardiac risk assessment was insufficient in three patients with preexisting cardiac disease, while 13 patients had symptoms and risk factors warranting intensive monitoring and evaluation.

CONCLUSION

Aortic dissection was the leading cause of maternal death due to CVDs. Obstetrics care providers need to be familiar with cardiac risk factors and clinical warning signs that may lead to impending fatal cardiac events. Timely risk assessment, patient awareness, and a multidisciplinary team approach are key to improving maternal care in Japan.

Cardiac and obstetric outcomes in pregnant women with heart disease: appraisal of the 2018 mWHO classification

OBJECTIVE

To appraise the application of the 2018 European Society of Cardiology-adapted modified WHO (mWHO) classification to pregnant women with heart disease managed at our maternal-fetal medicine referral centre and to assess whether the lack of a multidisciplinary Pregnancy Heart team has influenced their outcomes.

METHODS

A retrospective cohort study including all pregnancies with heart disease managed at our centre between June 2011 and December 2020. Cardiac conditions were categorised in five classes according to the mWHO classification. An additional class, named X, was created for conditions not included in this classification. Outcomes were compared among all classes and factors potentially associated to cardiac complications were assessed.

RESULTS

We identified 162 women with 197 pregnancies, for a prevalence of 0.7%. Thirty-eight (19.3%) gestations were included in class X. Caesarean section was performed in 64.9% pregnancies in class X, a rate similar to that of class II, II-III, and III/IV, and mostly for obstetric indications; in turn, it was more commonly performed for cardiology reasons in class II-III and III/IV. Cardiac complications occurred in 10.7%, with class X and II pregnancies showing the highest number of events (n=30.8% and 34.6%, respectively). Multiple gestation and urgent caesarean section associated with a 5-fold and 6.5-fold increase in complication rates.

CONCLUSIONS

Even in a maternal-fetal medicine referral centre, the lack of a multidisciplinary team approach to women with heart disease may negatively impact their outcomes.

Screening for Cardiovascular Disease in Pregnancy: Is There a Need?

Maternal mortality in the United States has been on the rise. Every year, about 700 women die from pregnancy-related complications. Cardiovascular disease (CVD) accounts for a large majority of pregnancy-related deaths driven by the lack of recognition and delays in diagnosis due to the overlap of normal pregnancy symptoms with those of CVD. Risk factors for CVD including race, advanced maternal age, hypertension, diabetes, obesity, socioeconomic status, and geographic region play an important role in CVD-related deaths. Several risk assessment models are available to stratify women with a known diagnosis of CVD. However, most women who die from CVD during pregnancy or the postpartum period do not have a prior diagnosis of CVD, and cardiomyopathy is an important contributor. The California Maternal Quality Care Collaborative (CMQCC) developed an algorithm to screen all pregnant and postpartum women to allow stratification into low or high risk for CVD. The algorithm has been validated in diverse patient populations. We propose universal CVD screening for all women in the antepartum and postpartum period to identify women at risk and to provide education and awareness for both patients and healthcare providers. This screening tool would work to reduce the increasing rates of severe maternal mortality and morbidity while having a significant impact on healthcare costs in the United States.
