    1. Influence of neoatherosclerosis on prognosis and treatment response in patients with in-stent restenosis

      Influence of neoatherosclerosis on prognosis and treatment response in patients with in-stent restenosis

      Introduction and objectives Neoatherosclerosis is one of the causes of in-stent restenosis (ISR). Our objective was to evaluate the influence of neoatherosclerosis on prognosis and treatment response in patients with ISR. Methods This is a pooled analysis of the optical coherence tomography (OCT)-substudies of 2 multicenter, randomized clinical trials, RIBS IV and V, comparing treatment with paclitaxel-coated balloon vs everolimus-eluting stent in patients with ISR. OCT evaluation was performed at baseline and at 6 to 9 months. Neoatherosclerosis was defined in baseline OCT as neointima with calcified or lipid content. We evaluated the angiographic and OCT results at 6 ...

    3. One-year optical coherence tomography findings in patients with late and very-late stent thrombosis treated with intravascular imaging guided percutaneous coronary intervention

      One-year optical coherence tomography findings in patients with late and very-late stent thrombosis treated with intravascular imaging guided percutaneous coronary intervention

      Patients with late/very-late stent thrombosis (ST) are at high risk of recurrent-ST. The mechanisms of recurrent-ST are largely unknown. The objective is to describe the 1-year optical coherence tomography (OCT) findings of patients suffering from late/very-late ST treated with intravascular imaging guided percutaneous coronary intervention (PCI). All consecutive patients with late/very-late ST undergoing intravascular imaging guided PCI were screened to undergo coronary angiography and OCT examination at 1 year. Patients were classified according to the observation of stent malapposition as most contributing cause of the ST. Thirty-four patients were included. Stent malapposition was observed in 17 (50 ...

    4. Five-Year Optical Coherence Tomography in Patients With ST-Segment–Elevation Myocardial Infarction Treated With Bare-Metal Versus Everolimus-Eluting Stents

      Five-Year Optical Coherence Tomography in Patients With ST-Segment–Elevation Myocardial Infarction Treated With Bare-Metal Versus Everolimus-Eluting Stents

      Background— The main causes of late (>1 month) stent thrombosis (ST) are stent uncoverage, malapposition, and neoatherosclerosis. First-generation drug-eluting stents were associated with higher rate of late ST compared with bare-metal stents (BMS), especially in patients with ST-segment–elevation myocardial infarction. Second-generation everolimus-eluting stents (EES) have shown similar rate of late ST than BMS. The aims of the study are to compare the ratio of uncovered to total struts per cross-section ≥30% and other optical coherence tomographic findings associated with ST between EES and BMS in patients with ST-segment–elevation myocardial infarction at 5 years. Methods and Results— One hundred ...

      Vascular Healing Evaluated by Intravascular Ultrasound and Optical Coherence Tomography | Revista Española de Cardiología (English Edition)

      A 34-year-old man with ST-segment elevation myocardial infarction was referred to our department for primary angioplasty. A coronary angiogram revealed thrombotic occlusion of the ostial left anterior descending artery, with protrusion of abundant thrombotic material into the left main coronary artery. After ineffective thromboaspiration, dilatation with a 2.0 mm × 15 mm balloon was performed and blood flow was restored, although a large thrombus remained ( Figure , red arrows). Intravascular ultrasound demonstrated the presence of an insignificant fissured plaque ( Figure , blue arrows), with abundant attached thrombotic material ( Figure , red arrows). We considered implanting a drug-eluting stent that would reach the left ...
