The ARMYDA FINISH multicenter study evaluated whether indexing intravascular ultrasound (IVUS)\u2010derived minimum lumen area (MLA) provides greater diagnostic accuracy than unindexed MLA for detecting hemodynamically significant LMCA stenoses, defined as a fractional flow reserve (FFR)\u2009\u2264\u20090.80.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifty\u2010two patients with angiographically\u2010intermediate isolated LMCA lesion were prospectively enrolled.

Primary endpoint was the diagnostic accuracy of MLA indexed to height, body surface area (BSA), body mass index (BMI) and left ventricular (LV) echocardiographic mass in identifying hemodynamically significant LMCA stenoses compared to unindexed MLA.
