This case study highlights recurrent transudative pleural effusion. Cardiac amyloidosis was ultimately diagnosed via endomyocardial biopsy, explaining the unexplained effusion.

Area of Science:

  • Cardiology
  • Internal Medicine
  • Pathology

Background:

  • Recurrent transudative pleural effusion can present a diagnostic challenge.
  • Initial investigations often fail to identify the underlying cause of persistent effusions.

Observation:

  • A patient presented with recurrent transudative pleural effusion.
  • Standard cardiovascular assessments did not reveal the etiology.
  • Cardiac catheterization revealed a characteristic "dip-plateau" pressure waveform.

Findings:

  • The "dip-plateau" finding on cardiac catheterization is suggestive of restrictive cardiomyopathy.
  • Endomyocardial biopsy confirmed the presence of cardiac amyloidosis.

Implications:

  • Cardiac amyloidosis should be considered in the differential diagnosis of recurrent transudative pleural effusions.
  • Advanced diagnostic techniques like endomyocardial biopsy are crucial for definitive diagnosis.
  • Early diagnosis of cardiac amyloidosis can lead to timely management and improved patient outcomes.
