cardiac catheterization laboratory
A specialized medical facility equipped for invasive cardiac diagnostic and therapeutic procedures using catheter-based techniques.
Full Definition
A cardiac catheterization laboratory, commonly called a cath lab, is a sterile procedural suite equipped with specialized imaging equipment and monitoring devices for invasive cardiac procedures. These facilities feature high-resolution fluoroscopy systems, hemodynamic monitoring equipment, and emergency resuscitation capabilities. Cath labs are used for diagnostic coronary angiography, percutaneous coronary interventions, electrophysiology studies, and structural heart procedures. The laboratory must meet strict radiation safety standards and maintain sterile conditions similar to an operating room. Staff typically includes interventional cardiologists, specialized nurses, and radiologic technologists.
Usage
Usage note: Can be abbreviated as 'cath lab' in informal contexts but should be spelled out fully in formal reports.
