Area of Science:

  • Cardiology
  • Pathology
  • Diagnostic Medicine

Background:

  • Myocardial diseases present diagnostic challenges, particularly when accompanied by heart failure or dysrhythmias.
  • Accurate histological diagnosis is crucial for effective management of cardiac conditions.

Purpose of the Study:

  • To evaluate the diagnostic utility of endomyocardial biopsy (EMB) in patients with suspected myocardial diseases.
  • To assess the safety and efficacy of EMB in a clinical setting.

Main Methods:

  • A prospective study involving 84 consecutive patients with clinically suspected myocardial diseases.
  • Histological analysis of endomyocardial biopsy samples.

Main Results:

  • EMB provided a specific diagnosis in 39.3% of patients and a confirmative diagnosis in 14.3%.

  • The procedure was particularly useful for diagnosing unexplained heart failure, idiopathic dysrhythmias, and differentiating restrictive cardiomyopathy from constrictive pericarditis.
  • EMB was performed safely with minimal morbidity and no mortality.

    • Conclusions:

    • Endomyocardial biopsy is a valuable diagnostic tool for patients with suspected myocardial diseases.
    • EMB offers significant diagnostic yield in complex cases of heart failure and arrhythmias.
    • The procedure is safe and well-tolerated, supporting its clinical application.
