The traditional advantages of the LEFT approach over the right:
comfort for right-handed patients, less tortuous vessel,
Ease of left internal breast angiography, easy manipulation of
catheters initially designed for the femoral approach.
|
Short compression time, facilitating outpatient PCI.
|
Better patient comfort (the left arm is placed comfortably with
the arm on a pillow on the patient’s left side, the forearm through
the abdomen and the hand in pronation on the right groin)
|
Preservation of the radial artery in the forearm for future
|
Greater operator comfort and safety (the operator can punch on
the right side.
