Summary
Transcatheter endomyocardial biopsy (EMB) provides valuable clinical information in over 50% of patients, particularly for diagnosing myocarditis in heart failure cases. While generally safe, left ventricular EMB shows higher complication rates than right ventricular EMB.
Area of Science:
- Cardiology
- Pathology
Context:
- Transcatheter endomyocardial biopsy (EMB) is an established diagnostic tool.
- Its clinical utility remains a subject of ongoing debate and investigation.
- This study reports experience with 182 EMB procedures in 156 patients.
Purpose:
- To evaluate the clinical value of transcatheter endomyocardial biopsy.
- To assess complication rates associated with EMB procedures.
- To identify patient subgroups where EMB provides significant diagnostic information.
Summary:
- EMB demonstrated significant clinical value in 63.5% of patients with congestive heart failure and dilated cardiomyopathy, revealing myocarditis in 17.5%.
- High clinical utility was also observed in restrictive/constrictive physiology, angina with normal coronaries, and young patients with atrioventricular block.
- Conversely, EMB showed limited value in idiopathic ventricular arrhythmias and aortic/mitral incompetence.
Impact:
- EMB is a safe procedure yielding crucial diagnostic insights in over half of cases.
- The study highlights a notable incidence of myocarditis (25/156 patients) and its varied clinical presentations.
- Findings support EMB's role in specific cardiac conditions, guiding clinical decision-making.
