Location Matters: left Heart Obstruction in Pregnancy

Isolated mitral stenosis and serial (>1) left heart obstructive lesions carry the highest risk of maternal cardiovascular events. We are the first to show higher event rates in women with serial left heart obstructive lesions. The data supports the need for specialized and experienced high-risk obstetric-cardiac teams to care for women with left heart obstruction, and demonstrates excellent outcomes in a complex cohort of pregnant women with all types of left heart obstruction.
