Values are n (%). The characteristics of the patients who underwent live transmission coronary procedures are compared with our routine 2010 experience and 66 matched controls.

CABG = coronary artery bypass grafting; IHD = ischemic heart disease; IVUS = intravascular ultrasound; LCX = left circumflex coronary artery; LMCA = left main coronary artery; NSTEMI = non–ST-segment elevation myocardial infarction; PCI = percutaneous coronary intervention; STEMI = ST-segment elevation myocardial infarction; VD = vessel disease; other abbreviations as in Table 1.

  • More than 1 territory was treated in several patients.

  • A combined procedure was done in 3 patients.
