PY - 2015 T2 - Maternal Medicine AB - Cardiac disease complicates only 1% to 4% of pregnancies in the United States, yet it is still the most important cause of nonobstetric maternal morbidity and mortality.1 Structural heart disease refers to an interruption of the natural flow of blood through the chambers and valves of the heart. The pathology may be congenital or acquired, typically involving myocardial and valvular lesions. Structural heart disease also includes noncoronary cardiovascular processes and the related interventional procedures to repair the defects.2 Ischemic disease (atherosclerosis of native coronary arteries) and cardiomyopathies presenting with pulmonary edema are discussed separately (see Chapters 6 and 8).
