The standard length of a coronary guide catheter is 100 cm. Occasionally, shorter lengths (85 or 90 cm) are required to reach very distal lesions (e.g. LAD lesions via the left internal mammary artery (LIMA), distal native arteries via sequential saphenous vein grafts (SVGs), or retrograde approach to chronic total occlusions (CTO)). Longer lengths (110–115 cm) are required for unusually tall patients or severely tortuous aorto‐iliac vessels. The use of a long sheath and of longer balloon catheters (>145 cm) has partially overcome this problem but stent delivery catheters remain 135 cm.
