Merit Offers Radial Internal Mammary Catheter for Navigating LIMA Grafts

Transradial cardiac catheterization in patients with previous coronary artery bypass graft surgery can be technically challenging.

Impress

Since the majority of CABG patients have a left internal mammary artery (LIMA) graft to the left anterior descending artery (LAD), many radial operators choose to perform catheterization procedures in CABG patients from a left radial approach using standard femoral diagnostic catheters. However, other operators have reported success with the right radial access to the LIMA. Right radial access for right radial LIMA angiography provides more comfortable access from the right side of the patient, reduces back strain, and the need to reach over the patient, especially patients who are obese.

For patients with LIMA grafts, Merit Medical now offers a Radial Internal Mammary catheter to facilitate navigation to the left internal mammary from the right transradial approach. The Merit Radial Internal Mammary catheter is available in 4F and 5F, 110 cm lengths. The Impress® material offers a highly torqueable shaft with a soft, tapered atraumatic tip.

Combining Merit’s broad offering of products for radial approach with your clinical expertise can help achieve the improved outcomes you expect from the radial approach including reduced complications, quicker ambulation, and increased patient comfort.
