Abstract
Background: Maternal cardiac disease is the major cause of maternal morbidity and mortality. Even though mitral stenosis (MS) is rare in the US, it is a high-risk condition during pregnancy.
Methods: This study is a retrospective review of the HCUP-NIS Database from 2002-2014. Inclusion criteria consisted of the presence of at least one billing code for pregnancy and at least one billing code for mitral stenosis (MS). The comparison group consists of the presence of at least one billing code for pregnancy and no billing code for MS. We compiled lists of codes for known co-occurrences and performed procedures.
Results: There were 2014 weighted discharges for both pregnancy and MS. The data contained 104 weighted discharges with MS in Pregnancy that underwent one cardiac intervention. Patients who had at least one diagnosis for MS had a larger mean cost per discharge. Pulmonary Hypertension (PH), Atrial Arrythmias (AA), Stroke and Heart Failure (HF) were respectively reported in 25.71%, 7.14%, 0.95% and 19.28% of the discharges with billing code for MS and pregnancy whereas in patients without billing codes for MS only 0.04%, 0.07%, 0.05%, 0.22% had those conditions. No deaths were identified in this group.
Conclusion: Our study identified a low incidence of MS in the USA over our 12-year study period. Our results substantiate MS as a risk factors for PH, AA, HF and stroke in pregnant patients. Even though, the mortality is low, it is important that clinicians be aware of this diagnosis due higher costs and morbidity.
