ABSTRACT We describe the case of a patient with multiple comorbidities scheduled to undergo intracoronary optical coherence tomography-guided percutaneous coronary intervention. Based on the images acquired, it was possible to observe the mechanism of restenosis and the anatomy of the lesion, and to optimize planning of the procedure. Our strategy was to resect the neointimal hyperplastic tissue using laser atherectomy, with great results and a successful procedure.

ABSTRACT Optical coherence tomography is an intravascular imaging tool that has been increasingly used in the cardiac catheterization laboratory. Since its spatial resolution is approximately ten-fold greater than intracoronary ultrasound, optical coherence tomography assists in the anatomical differential diagnosis of coronary lesions with atypical presentation. In this report, we present a case of a female patient with a history of acute coronary syndrome and, currently, with a complex angiographic lesion, with the aspect of a chronic dissection in the anterior […]
