Cardiac Catheterization
Invasive diagnostic procedure using catheters to evaluate heart structure and function.
Full Definition
Cardiac catheterization is an invasive diagnostic and therapeutic procedure involving the insertion of thin, flexible tubes (catheters) into the heart chambers and blood vessels to evaluate cardiac anatomy, hemodynamics, and function. In congenital cardiology, the procedure provides detailed pressure measurements, oxygen saturations, angiographic imaging, and assessment of shunt flows that are crucial for surgical planning and ongoing management. Modern catheterization also includes interventional capabilities such as balloon dilations, device closures, and stent placement. The procedure requires conscious sedation or general anesthesia in pediatric patients and is typically performed in specialized cardiac catheterization laboratories. Comprehensive hemodynamic assessment includes measurement of pressures, resistances, and calculation of shunt ratios.
Usage
Usage note: Often abbreviated as 'cardiac cath' in informal clinical communication.
