title: Problems in the detection of acute severe mitral insufficiency using flow-directed catheters.
abstract: A case of acute severe mitral insufficiency is described wherein bedside Swan-Ganz right heart catheterization failed to established the diagnosis. Emphasis is given to problems inherent in recording the diagnostic large dominant V-waves with this technique, and to the necessity of resolving conflicting measurements with conventional cardiac catheterization.
