|Patient Age (Yrs)||Target Vessel||Complication||Treatment|
|53||LAD||Before initiation of protocol, a focal spasm in the LCX was visualized while the Doppler wire was in the LAD, causing an MI and prolonged chest pain.||Patient was given IC nitroglycerin and verapamil, as well as sublingual and intravenous nitroglycerin. She was admitted with a peak CPK of 532 and positive MB fraction.|
|58||LAD||A nonflow-limiting coronary dissection of the mid LAD resulted from advancement of the Doppler wire. Focal vasospasm and staining were visualized after the acetylcholine injection. IC nitroglycerin appropriately dilated the vessel.||TIMI flow grade 3 was present, and no intervention was needed. Patient was given clopidogrel and monitored overnight. She did not experience additional chest pain. There were no electrocardiographic changes.|
CPK = creatine phosphokinase; CRT = coronary reactivity testing; IC = intracoronary; LAD = left anterior descending coronary artery; LCX = left circumflex coronary artery; MB = myocardial band; MI = myocardial infarction; SAE = serious adverse event(s); TIMI = Thrombolysis In Myocardial Infarction.
