Optical coherence tomography and coronary angiography as complement in therapeutic decisions
Keywords:
optical coherence tomography, coronary angiography, coronary disease, cardiovascular diagnosis techniquesAbstract
Optical coherence tomography is an intracoronary diagnostic technique of high resolution, and its arrival has allowed a better diagnosis for the treatment of vascular diseases. The development of new systems for this tomography, which prevent artery occlusion, allows this technique to have greater utility and become standard practice in the hemodynamic laboratories for the characterization of coronary atherosclerotic plaque and for evaluating the inserted stent. The case of a patient that during an acute coronary syndrome with ST segment elevation was treated with thrombolytics and no signs of reperfusion were achieved is presented. Coronary angiography showed no significant stenosis regarding infarct topography, so an optical coherence tomography was performed and an image compatible with neointimal proliferation and thrombus within the previously inserted stent in the circumflex artery was diagnosed, which corresponded with ECG changes. It was decided to apply percutaneous treatment with drug-eluting stent implantation.
