To the Editor:
We read with interest the results of the DOCTORS study (Does Optical Coherence Tomography Optimize Results of Stenting) of the use of optical coherence tomography to optimize stent implantation in non-ST-elevation myocardial infarction.1 The finding that stent underexpansion detected by optical coherence tomography occurs in 42% of implants and often goes undetected by angiography is sobering and calls for the interventional …
