BACKGROUND: The pattern of saphenous vein graft (SVG) calcification before percutaneous intervention has not been studied. METHODS AND RESULTS: We used diagnostic and preintervention intravascular ultrasound (IVUS) to determine the incidence and magnitude of SVG calcification in 334 SVG lesions in 274 consecutive patients. Calcium was found in 133 SVGs (40%). Calcium was uniformly distributed among 48 lesion sites (14%), 43 proximal references (13%), and 42 distal references (13%). Calcium was superficial in 20 (40%) and deep in 28 (60%). Over the entire length of the SVGs, the maximum arc and length of calcium (in calcium-containing SVGs) averaged 174+/-107 degrees and 6.8+/-4.8 mm, respect..View full abstract
