A et al. Influence of time-to-treatment, TIMI-flow grades, and ST-segment resolution on infarct size and infarct transmurality as assessed by delayed enhancement magnetic resonance imaging. Detection of TIMI-3 flow before mechanical reperfusion with ultrasonic tissue characterization in patients with anterior wall acute myocardial infarction. Significance of a coronary artery with Thrombolysis in Myocardial Infarction grade 2 flow 'patency' (outcome in the thrombolysis and angioplasty in myocardial infarction trials).cance of epicardial blood flow before and after percutaneous coronary intervention in patients with acute coronary syndromes. Exenatide reduces reperfusion injury in patients with ST-segment elevation myocardial infarction. et al. Normal flow (TIMI-3) before mechanical reperfusion therapy is an independent determinant of survival in acute myocardial infarction: analysis from the primary angioplasty in myocardial infarction trials. CM et al. Predicting late myocardial recovery and outcomes in the early hours of ST-segment elevation myocardial infarction traditional measures compared with microvascular obstruction, salvaged myocardium, and necrosis characteristics by cardiovascular magnetic resonance. A et al. Impact of early vs. late microvascular obstruction assessed by magnetic resonance imaging on long-term outcome after ST-elevation myocardial infarction: a comparison with traditional prognostic markers. Upper panel. A 36-year-old male with progressive exertional angina, inducible anterolateral is-chaemia, and single-vessel disease involving the bifurcation left anterior descending coronary artery (LAD)/first diagonal branch (Panel 1A). Panel 1B shows the three-dimensional (3D)-optical coherence tomography (OCT) image of a 2.75 × 28 mm Integrity RESOLUTE w stent with a wire crossing the struts, demonstrating that the wire crossed through the most distal cell of the side-branch ostium. Panel 1C shows the 3D-OCT image after a 2.5 mm balloon has been dilated at 12 atm across the origin with a 3.0 mm balloon inflated in the LAD (kissing balloon). A perfect circular opening with no strut malapposition in the ostium is obtained. Lower panel. A 72-year-old woman with exertional angina and a severe lesion in the bifurcation of LAD/first diagonal branch (Panel 2A). Three-dimensional OCT image (Panel 2B) shows the struts of a similar stent (3.0 × 24 mm Integrity RESOLUTE w) jailing the ostium of the side branch. OCT was not used to identify the position of wire crossing. Panel 2C indicates that despite dilatation of the diagonal ostium with a 2.5 mm balloon with a 3.0 mm balloon in the LAD, a gross malapposition of the main vessel stent struts persists at the origin of the diagonal. The wire is clearly positioned in the …
