title: Right upper lobe pulmonary edema after mitral valve replacement caused by paravalvular leakage recognized by bedside transesophageal echocardiography.
abstract: OBJECTIVE
  To describe an unusual case of right upper lobe pulmonary edema caused by acute paravalvular leakage that was identified by the use of bedside transesophageal echocardiography.
  
  
  METHODS
  Case report.
  
  
  METHODS
  University-affiliated hospital.
  
  
  METHODS
  A 59-yr-old male patient underwent prosthetic mitral valve replacement (St. Jude valve) for severe mitral regurgitation and developed sudden onset of dyspnea and change in consciousness with blood pressure decreased to 70/30 mm Hg. Elevation of central venous pressure and images of transthoracic echocardiography led to the diagnosis of cardiac tamponade.
  
  
  CONCLUSIONS
  Acute paravalvular leakage after mitral valvular replacement should be considered as one of the differential diagnoses for unilateral pulmonary edema. Physical findings of a holosystolic murmur and findings from bedside transesophageal echocardiography can confirm the diagnosis, avoiding delay in management.
