Case Report Navarrete et al Vasospasm during exertion Arq Bras Cardiol. 2019; 113(1):106-108 Figure 1 – ICA after stress echocardiogram. A) ICA in caudal right oblique projection that demonstrates mild plaque in proximal LAD. B) ICA in left anterior oblique projection that showed severe obstruction in RCA (arrow). C) ICA in left anterior oblique projection after the implant of bioabsorbable scaffold in RCA. ICA: invasive coronary angiography LAD: left anterior descending artery. RCA: right coronary artery. Figure 2 – ECG during treadmill test, pressure guide pre and post vasospasm test, and ICA post vasospasm test. A) ECG during treadmill test showed ST elevation in V1-V4 leads. B) FFR value in proximal LAD which discarded functional significance of this lesion. C) ICA after methylergonovine injection confirmed focal vasospasm in LAD. Panel D: FFR value after methylergonovine injection that demonstrated functional significance of vasospasm. ICA: invasive coronary angiography; FFR: fractional flow reserve; LAD: left anterior descending artery. Sources of Funding There were no external funding sources for this study.
