Internal mammary cannulation poses technical and time challenges; Level 5 evidence leaves open whether alternatives improve efficiency.
Internal mammary angiography can involve substantial technical hurdles and time delays, prompting the need for alternative cannulation methods such as PTCA guidewires or balloon occlusion catheters.
Kuntz et al. (1990) conducted a review in Prior coronary bypass operations requiring internal mammary artery angiography (n=87). Internal mammary artery angiography techniques was evaluated on Time from catheter insertion to selective IMA angiography. Cannulation of the right and left internal mammary arteries involves substantial technical hurdles, resulting in a mean time of 19 +/- 19 minutes from catheter insertion to selective angiography.
