Describes a novel pulmonary venous flow pattern in a patient with severe mitral regurgitation due to endocarditis-induced leaflet perforation.
Pulmonary venous flow patterns have been well described in the literature to assess severity of mitral regurgitation (MR) and the degree of diastolic dysfunction. We report a case of posterior mitral leaflet perforation due to bacterial endocarditis causing an alteration of pulmonary venous flow, not previously described in the literature. This pulmonary venous flow pattern is unique in that it reflects dynamic changes in left atrial pressure in the background of severe MR.
