title: Clinical implication of inadvertent monitoring of pulmonary artery pressure via a "left atrial" catheter.
abstract: A patient is described in whom a left atrial catheter was inadvertently wedged in a pulmonary vein following mitral valve replacement. The pulmonary vein wedge pressure obtained approximated the pulmonary artery pressure and was suggestive of paraprosthetic mitral valve regurgitation.
