Insights
This study explores the feasibility of left ventricular endomyocardial biopsy (LV-EMB) using a transradial approach. This novel technique aims to improve diagnostic procedures for unexplained cardiomyopathy.
Area of Science:
- Cardiology
- Interventional Cardiology
- Diagnostic Procedures
Background:
- Endomyocardial biopsy (EMB) plays a role in diagnosing unexplained cardiomyopathies, but its use and technique remain debated.
- Right ventricular EMB is common, while left ventricle (LV) EMB is less accepted due to safety concerns, typically accessed via the femoral artery.
- The transradial approach is established as safe and feasible for various cardiac catheterization procedures.
Abstract:
The role of endomyocardial biopsy (EMB) in the diagnosis and treatment of adults presenting a newly unexplained cardiomyopathy remains controversial and the clinical indication varies among different centers. Furthermore, the choice of the ventricular site for EMB is still under debate. The right ventricular EMB is commonly used due to safety features and left ventricle (LV) EMB has not yet gained acceptance because of concerns about possible complications. Of note, when LV-EMB is performed, the femoral artery is usually the access site. There is a large body of evidence supporting the safety and feasibility of transradial approach in a broad spectrum of patients and settings in the catheterization laboratory. Therefore, the aim of the present manuscript is to report the feasibility of performing a LV-EMB by the transradial approach using a sheathless guiding catheter as an ad hoc procedure.
