title: Evaluation of operatively excised cardiac valves: etiologic determination of valvular heart disease.
abstract: Morphologic evaluation of operatively excised native cardiac valves can lead to an etiologic diagnosis in most instances using a simple 10-step approach. With few exceptions, histologic evaluation of excised cardiac valves provides little additional information beyond this proposed morphologic assessment.
