title: Application of intracoronary flow velocity for detection and management of ostial saphenous vein graft lesions.
abstract: Ostial lesions of saphenous vein grafts can be difficult to assess by angiography. A physiologic approach to the selection and recanalization of ostial lesions in saphenous vein grafts may be advantageous to overcome limitations of angiography. To assist in identifying favorable physiology and facilitate procedural decision making, the use of coronary flow velocity measurements with a Doppler-tipped 0.018-inch angioplasty flowire in three particularly difficult patients with varying types of saphenous vein graft aorto-ostial narrowings is reported.
