At baseline, mean FFR was 0.91\u00b10.06, declining to 0.89\u00b10.06 upon dobutamine infusion (p&lt;0.001). Dobutamine stress FFR was significant (\u22640.8) in three patients (8.1%), two of whom were surgically treated. Following surgery, dobutamine stress FFR rose from 0.76 to 0.94 and 0.76 to 0.98. Remodelling index (r=0.583, p=0.002), minimal lumen area (diastole: r=0.580, p=0.002; systole: r=0.0618, p&lt;0.001) and per cent area stenosis (r=\u20130.550, p=0.004), measured by intravascular ultrasound, correlated with dobutamine stress FFR. To assess the clinical relevance, follow-up data of 119 patients with lone right ACAOS with interarterial course were analysed retrospectively. Two deaths occurred during a median follow-up period of 4\u2005years, for a mortality rate of 0.34 per 100 person-year. No instances of myocardial infarction were recorded and one patient did undergo surgical revascularisation in the course follow-up.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Most instances of lone right ACAOS with interarterial course discovered in adults were physiologically insignificant and ran benign clinical courses.
