TY - CHAP M1 - Book, Section TI - Chapter 47. Multiple Valve Disease A1 - Schaff, Hartzell V. A1 - Suri, Rakesh M. A2 - Cohn, Lawrence H. PY - 2012 T2 - Cardiac Surgery in the Adult, 4e AB - Pathologic changes in the cardiac valves requiring surgical correction of more than one valve can result from rheumatic heart disease, degenerative valve diseases, infective endocarditis, and a number of miscellaneous causes. Further, valve dysfunction may be primary; that is, a direct result of a disease process, or secondary; that is, caused by cardiac enlargement and/or pulmonary hypertension. Surgical management is influenced both by the underlying cause of valve dysfunction and, when valves are involved secondarily, by the anticipated response to replacement or repair of the primary valve lesion. In addition, the consequences of various combinations of diseased valves on left and right ventricular geometry and function frequently are different from the remodeling as a result of single-valve disease. This chapter addresses pathophysiologic considerations in multivalvular heart disease, surgical techniques, and management of commonly encountered etiologies.
