Delivery outcomes associated with maternal congenital heart disease, 2000-2018.

ABSTRACT:

Purpose

To characterize temporal trends and outcomes of delivery hospitalization with maternal congenital heart disease (CHD).

Materials and methods

For this repeated cross-sectional analysis, deliveries to women aged 15-54 years with maternal CHD were identified in the 2000-2018 National Inpatient Sample. Temporal trends in maternal CHD were analyzed using joinpoint regression to estimate the average annual percentage change (AAPC) with 95% CIs. The relationship between maternal CHD and several adverse maternal outcomes was analyzed with log-linear regression models. Risk for adverse outcomes in the setting of maternal CHD was further characterized based on additional diagnoses of cardiac comorbidity including congestive heart failure, arrhythmia, valvular disease, pulmonary disorders, and history of thromboembolism.

Results

Of 73,109,790 delivery hospitalizations, 51,841 had a diagnosis of maternal CHD (7.1 per 10,000). Maternal CHD rose from 4.2 to 10.9 per 10,000 deliveries (AAPC 4.8%, 95% CI 4.2%, 5.4%). Maternal CHD deliveries with a cardiac comorbidity diagnosis also increased from 0.6 to 2.6 per 10,000 from 2000 to 2018 (AAPC 8.4%, 95% CI 6.3%, 10.6%). Maternal CHD was associated with severe maternal morbidity (adjusted risk ratios [aRR] 4.97, 95% CI 4.75, 5.20), cardiac severe maternal morbidity (aRR 7.65, 95% CI 7.14, 8.19), placental abruption (aRR 1.30, 95% 1.21, 1.38), preterm delivery (aRR 1.47, 95% CI 1.43, 1.51), and transfusion (aRR 2.28, 95% CI 2.14, 2.42). Risk for severe morbidity (AAPC 4.7%, 95% CI 2.5%, 6.9%) and cardiac severe morbidity (AAPC 4.7%, 95% CI 2.5%, 6.9%) increased significantly among women with maternal CHD over the study period. The presence of cardiac comorbidity diagnoses was associated with further increased risk.

Conclusion

Maternal CHD is becoming more common among US deliveries. Among deliveries with maternal CHD, risk for severe morbidity is increasing. These findings support that an increasing burden of risk from maternal CHD in the obstetric population.

Project description:BackgroundWomen with congenital heart disease (CHD) may be at increased risk for adverse events during pregnancy and delivery.ObjectiveTo compare delivery outcomes between women with and without CHD.Design, setting, and participantsThis retrospective study of inpatient delivery admissions in the Healthcare Cost and Utilization Project's California State Inpatient Database compared maternal and fetal outcomes between women with and without CHD by using multivariate logistic regression. Female patients with codes for delivery from the International Classification of Diseases, Ninth Revision, from January 1, 2005, through December 31, 2011, were included. The association of CHD with readmission was assessed to 7 years after delivery. Cardiovascular morbidity and mortality were hypothesized to be higher among women with CHD. Data were analyzed from April 4, 2014, through January 23, 2017.ExposuresNoncomplex and complex CHD.Main outcomes and measuresMaternal outcomes included in-hospital arrhythmias, eclampsia or preeclampsia, congestive heart failure (CHF), length of stay, preterm labor, anemia complicating pregnancy, placental abnormalities, infection during labor, maternal readmission at 1 year, and in-hospital mortality. Fetal outcomes included growth restriction, distress, and death.ResultsAmong 3 642 041 identified delivery admissions, 3189 women had noncomplex CHD (mean [SD] age, 28.6 [7.6] years) and 262 had complex CHD (mean [SD] age, 26.5 [6.8] years). Women with CHD were more likely to undergo cesarean delivery (1357 [39.3%] vs 1 164 509 women without CHD [32.0%]; P < .001). Incident CHF, atrial arrhythmias, ventricular arrhythmias, and maternal mortality were uncommon during hospitalization, with each occurring in fewer than 10 women with noncomplex or complex CHD (<0.5% each). After multivariate adjustment, noncomplex CHD (odds ratio [OR], 9.7; 95% CI, 4.7-20.0) and complex CHD (OR, 56.6; 95% CI, 17.6-182.5) were associated with greater odds of incident CHF. Similar odds were found for atrial arrhythmias in noncomplex (OR, 8.2; 95% CI, 3.0-22.7) and complex (OR, 31.8; 95% CI, 4.3-236.3) CHD, for fetal growth restriction in noncomplex (OR, 1.6; 95% CI, 1.3-2.0) and complex (OR, 3.5; 95% CI, 2.1-6.1) CHD, and for hospital readmission in both CHD groups combined (OR, 3.6; 95% CI, 3.3-4.0). Complex CHD was associated with greater adjusted odds of serious ventricular arrhythmias (OR, 31.8; 95% CI, 4.3-236.3) and maternal in-hospital mortality (OR, 79.1; 95% CI, 23.9-261.8).Conclusions and relevanceIn this study of hospital admissions for delivery in California, CHD was associated with incident CHF, atrial arrhythmias, and fetal growth restriction and complex CHD was associated with ventricular arrhythmias and maternal in-hospital mortality, although these outcomes were rare, even in women with complex CHD. These findings may guide monitoring decisions and risk assessment for pregnant women with CHD at the time of delivery.

Project description:ImportanceWith the help of medical advances, more women with adult congenital heart disease (ACHD) are becoming pregnant. Adverse maternal, obstetric, and neonatal events occur more frequently in women with ACHD than in the general obstetric population. Adult congenital heart disease is heterogeneous, yet few studies have assessed whether maternal and neonatal outcomes differ across ACHD subtypes.ObjectiveTo assess the association of ACHD and its subtypes with pregnancy, maternal, and neonatal outcomes.Design, setting, and participantsThis cross-sectional study used data from the Discharge Abstract Database, which contains information on all hospitalizations in Canada (except Quebec) from fiscal years 2001-2002 through 2014-2015. Discharge Abstract Database information was linked with maternal and infant hospital records across Canada. All women who gave birth in hospitals during the study period were included in the study. Data were analyzed from December 18, 2017, to March 22, 2019.ExposuresWomen with ACHD were identified using diagnostic and procedural codes. Subtypes of ACHD were classified using the Anatomic and Clinical Classification of Congenital Heart Defects scheme.Main outcomes and measuresPrimary outcomes were defined a priori and included severe maternal morbidity (measured using the Maternal Morbidity Outcomes Indicator), neonatal morbidity and mortality (measured using the Neonatal Adverse Outcomes Indicator), ischemic placental disease, preterm birth, congenital anomalies, and small-for-gestational-age births. Absolute and relative rates of each outcome were calculated overall and by ACHD subtype. Logistic regression using generalized estimating equations assessed crude and adjusted odds ratios (aORs) for each outcome in women with ACHD compared with women without ACHD after adjustment for comorbidities, mode of delivery, and study year.ResultsThe 2114 women with ACHD included in the analysis (mean [SD] age, 29.4 [5.7] years) had significantly higher odds of maternal morbidity (aOR, 2.7; 95% CI, 2.2-3.4) and neonatal morbidity and mortality (aOR, 1.8; 95% CI, 1.6-2.1) compared with women without ACHD (n = 2 682 451). Substantial variation was observed between women with different subtypes of ACHD. For example, the aORs of preterm birth (<37 weeks) varied from 0.4 (95% CI, 0.4-0.5) for women with anomalies of atrioventricular junctions and valves to 4.7 (95% CI, 2.9-7.5) for women with complex anomalies of atrioventricular connections.Conclusions and relevanceThese results suggest that women with different subtypes of ACHD are not uniformly at risk for adverse maternal and neonatal outcomes. Although some women with ACHD can potentially expect healthy pregnancies, it appears that clinical care should be modified to address the heightened risks of certain ACHD subtypes.

Project description:Background Clinical risk factors in neonatal cardiac surgery do not fully capture discrepancies in outcomes. Targeted metabolomic analysis of plasma from neonates undergoing heart surgery with cardiopulmonary bypass was performed to determine associations with clinical outcomes. Methods and Result Samples and clinical variables from 149 neonates enrolled in the Corticosteroid Therapy in Neonates Undergoing Cardiopulmonary Bypass trial with surgical treatment for congenital heart disease between 2012 and 2016 were included. Blood samples were collected before skin incision, immediately after cardiopulmonary bypass, and 12 hours after surgery. Outcomes include composite morbidity/mortality (death, extracorporeal membrane oxygenation, cardiac arrest, acute kidney injury, and/or hepatic injury) and a cardiac composite (extracorporeal membrane oxygenation, cardiac arrest, or increase in lactate level), hepatic injury, and acute kidney injury. Targeted metabolite levels were determined by high-resolution tandem liquid chromatography and mass spectrometry. Principal component and regression analyses were used to assess associations between metabolic profiles and outcomes, with 2 models created: a base clinical model and a base model+metabolites. Of the 193 metabolites examined, 40 were detected and quantified. The first principal component, principal component 1, was composed mostly of preoperative metabolites and was significantly associated with the composite morbidity/mortality, cardiac composite, and hepatic injury outcomes. In regression models, individual metabolites also improved model performance for the composite morbidity/mortality, cardiac composite, and hepatic injury outcomes. Significant disease pathways included myocardial injury (false discovery rate, 0.00091) and heart failure (false discovery rate, 0.041). Conclusions In neonatal cardiac surgery, perioperative metabolites were associated with postoperative outcomes and improved clinical model outcome associations. Preoperative metabolite levels alone may improve risk models and provide a basis for optimizing perioperative care.
