title: Intravascular ultrasound in equivocal coronary angiography.
abstract: Intravascular ultrasound (IVUS) is a well-established diagnostic tool that supplements coronary angiography in the evaluation of angiographical intermediate lesions as well as guiding Percutaneous transluminal coronary angioplasty. In this case report we describe the benefit of IVUS in diagnosing pseudostenosis as opposed to angiographically suspected guidewire induced dissection, and suggest the use of IVUS in all cases where angiography is equivocal. We also report a case of preoperative IVUS where the IVUS finding resulted in further coronary artery bypass grafting and suggest IVUS as a feasible alternative to probing of coronary arteries suspected of stenosis during coronary artery bypass grafting.
