Abstract
The transradial approach (TRA) has gained popularity in recent years mainly because of the significantly decreased access-site complications and the greater patient comfort it offers. In this paper, we describe the successful use of an extra-long hydrophilic-coated sheath for coronary angiography via the TRA in the presence of a severely dilated ascending aorta in a patient with severe tortuosity of the right subclavian artery.
