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).
