Iatrogenic Coronary Artery Dissection Induced During Invasive Absolute Coronary Blood Flow Measurement: Optical Coherence Tomography Findings
A 65-year-old woman with previous history of hypertension was referred to our institution due to effort angina with a positive exercise stress test. Coronary angiography showed normal coronary arteries. A vasospasm provocation test with methylergonovine was negative. With the aim of assessing the state of microvasculature, absolute coronary blood flow by thermodilution was performed as previously described.
