Why the study?
Does the combination of IVUS and FFR improve the diagnostic assessment of ambiguous left main coronary artery stenosis?
Does the combination of IVUS and FFR improve the diagnostic assessment of ambiguous left main coronary artery stenosis?
The combined use of IVUS and FFR improves the diagnostic assessment of ambiguous left main coronary artery stenoses, which are often difficult to evaluate by angiography alone.

May support IVUS/FFR for ambiguous LMCA assessment; hypothesis-generating pending prospective outcome trials.
The angiographic assessment of an ambiguous left main coronary artery (LMCA) stenosis is often difficult and not reliable. Intravascular ultrasound (IVUS) and fractional flow reserve (FFR) have improved the diagnostic utility of an ambiguous LMCA stenosis. The combined role of FFR and IVUS in patients with an ambiguous LMCA stenosis is discussed. Catheter Cardiovasc Interv 2004;62:349–357.
