Catheterisation Left and Right Coronary Arteries
UKETS・8 minutes read
Alan Bagnall demonstrates left coronary artery catheterization using a guide wire and catheter, followed by right coronary artery catheterization with a different type of catheter, detailing the process step by step. Proper sizing, positioning, and technique are crucial to successfully navigate the arterial tree and obtain clear angiographic images for diagnosis and treatment.
Insights
- Alan Bagnall performs left coronary artery catheterization by precisely navigating a guide wire and catheter through the arterial tree, ensuring accurate positioning for contrast injection.
- The process involves meticulous steps, including advancing the guide catheter around the aortic arch, potential redirection to avoid the left subclavian artery, and obtaining an angiogram in a specific view to outline the left mainstem and circumflex artery, culminating in successful catheterization.

Recent questions
How is left coronary artery catheterization performed?
Left coronary artery catheterization involves inserting a J tip guide wire through the femoral sheath, navigating it to the ascending aorta, and threading a jug kins left 4 guide catheter over it. The guide catheter is advanced around the aortic arch to reach the left main ostium for contrast injection, ensuring proper positioning without resistance.
What is the process for taking an angiogram in left coronary artery catheterization?
To take an angiogram in left coronary artery catheterization, a PA cranial view is used to outline the left mainstem and circumflex artery. This step follows the proper positioning and pressure check of the catheter, ensuring accurate visualization of the left coronary artery.
How is redirection handled during left coronary artery catheterization?
Redirection during left coronary artery catheterization may be necessary if the guide catheter heads into the left subclavian artery. In such cases, the catheter needs to be carefully advanced around the aortic arch to reach the left main ostium for contrast injection.
What is the technique for engaging the right coronary artery during catheterization?
Engaging the right coronary artery during catheterization involves advancing a juggins right 4 diagnostic catheter from the femoral artery into the aortic root. Careful torque application is then used to engage the right coronary artery ostium, followed by contrast injection and cine run for visualization.
How are appropriate sizes selected for left coronary artery catheterization?
In left coronary artery catheterization, appropriate sizes for the J tip guide wire and jug kins left 4 guide catheter are selected based on patient characteristics. This ensures smooth navigation through the arterial tree to the ascending aorta and proper positioning without resistance during the procedure.

Left and Right Coronary Artery Catheterization
- Alan Bagnall demonstrates catheterization of the left coronary artery using a J tip guide wire and a jug kins left 4 guide catheter, selecting appropriate sizes based on patient characteristics.
- The guide wire is inserted through the femoral sheath, navigated through the arterial tree to the ascending aorta, and the guide catheter is threaded over it, ensuring proper positioning without resistance.
- The guide catheter is advanced around the aortic arch, with potential redirection needed if it heads into the left subclavian artery, ultimately reaching the left main ostium for contrast injection.
- After ensuring proper catheter positioning and pressure, an angiogram is taken in a PA cranial view to outline the left mainstem and circumflex artery, completing left coronary artery catheterization.
- Moving on to the right coronary artery, a juggins right 4 diagnostic catheter is advanced from the femoral artery into the aortic root, with careful torque application to engage the right coronary artery ostium, followed by contrast injection and cine run for visualization.
