The catheters necessary for cardiac catheterization can be inserted either into the femoral artery (in the groin), or into the radial artery (in the wrist). The femoral artery is a larger vessel and provides a more direct route to the heart.
Transradial artery access for percutaneous coronary intervention is associated with lower bleeding and vascular complications than transfemoral artery access, especially in patients with acute coronary syndromes.
Nonbleeding complications such as radial artery spasm and radial artery occlusion are typically less morbid but occur much more frequently. Strategies to prevent TRA complications are essential and include the use of contemporary access techniques that limit arterial injury.
Radial artery access is when the interventional cardiologist uses the radial artery in the wrist as the entry point for the catheter. The cardiologist threads the thin catheter through the body’s network of arteries in the arm and into the chest, eventually reaching the heart.
Transradial access (TRA) can be used for primary PCI to reduce vascular complications and bleeding in cardiac catheterization laboratories with appropriate training and expertise in radial access procedures.
Recently, the distal radial artery from the anatomical snuffbox on the dorsal side of the hand (“distal TRA” or “snuffbox access”) has emerged as an alternative access to the conventional forearm radial artery for coronary angiography and interventions.
Transradial cardiac catheterization is a procedure used to treat and diagnose certain heart conditions. It's also called a transradial cardiac cath or angiography. During the procedure, a healthcare provider inserts a long thin tube (catheter) through the radial artery.
A “radial first” strategy should be considered in all diagnostic and interventional cardiac catheterization cases, including primary percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction (STEMI), to reduce bleeding and local vascular complications, decrease mortality, and improve patients’ comfort.1 Right ...
Transradial and transfemoral are two main approaches which are used as a diagnostic and therapeutic purpose in catheterization. The transradial approach in interventional cardiology is safe, effective, and feasible as compared to the transfemoral approach.
There are several advantages of radial artery access over transfemoral and transbrachial techniques, including (1) reduced duration of postprocedure bed rest and length of stay, enhancing patient comfort; (2) lower incidence of access site complications, including bleeding, pseudoaneurysm, and arteriovenous fistulas; and (3) potential ...
