Intravascular ultrasound in equivocal coronary angiography

Intravascular ultrasound (IVUS) is a well-established diagnostic tool that supplements coronary angiography in the evaluation of angiographical interm ediate lesions as well as guiding Percutaneous transluminal coronary angiop lasty. In this case report we describe the benefit of IVUS in diagnosing ps eudostenosis as opposed to angiographically suspected guidewire induced dis section, and suggest the use of IVUS in all cases where angiography is equi vocal. We also report a case of preoperative IVUS where the ni us finding r esulted in further coronary artery bypass grafting and suggest IVUS as a fe asible alternative to probing of coronary arteries suspected of stenosis du ring coronary artery bypass grafting.
