The YUMIKO™ catheter: a useful tool for angiography of the right internal mammary artery via a right brachial approach

Abstract

The YUMIKO™ catheter (Goodman, Nagoya, Japan) was recently developed for a left internal mammary artery (IMA) angiography with a right radial or brachial approach. The present authors experienced an interesting case where the YUMIKO catheter was useful for a right IMA angiography via a right brachial artery. A 53-year-old man with bilateral IMA grafts underwent follow-up coronary angiography via a right brachial artery. Native coronary artery and left IMA angiography were performed without difficulty using the Judkins Right and Left and YUMIKO catheters. Angiography of the right IMA was attempted with the Judkins Right catheter and IMA catheter, resulting in a nonselective angiogram with poor imaging. The YUMIKO catheter, however, enabled smooth cannulation to the right IMA and provided good images of the selective right IMA angiography. (Int J Cardiovasc Intervent 2003; 5: 98-101)
