The main predictor of adverse outcomes (thrombosis and restenosis) after implantation of a stent is the degree of expansion according to published studies using coronary intravascular ultrasound (IVUS). It is unknown whether optical coherence tomography (OCT), in this sense, provides similar information as the IVUS. The aim of this study was to compare the degree...

This multicenter, prospective, randomized controlled study was designed to evaluate the noninferiority of guided angioplasty by optical frequency domain (OFDI) compared to IVUS. 800 elective patients randomized 1: 1 were included. The diameter of the stent in the IVUS group was higher than in the OFDI group (p = 0.03). Post implant angiography showed a...

While the use of intravascular ultrasound (IVUS) during coronary intervention proved useful in multiple studies, there is limited evidence in the literature regarding its use in specifically in chronic total occlusions. The IVUS may help guide in recognizing the true lumen and better distal positioning, better coverage of stent, an optimal apposition and expansion, diagnose...

This study is still in progress and includes patients using SYNTAX II score based on functional invasive evaluation with iFR / FFR and performing angioplasty guided by IVUS using the biodegradable polymer everolimus eluting stent. The study seeks to prove superiority versus the first generation paclitaxel-eluting stent and non-inferiority versus surgery using historical data. We...

Contrast nephropathy is associated with increased morbidity and so this study evaluates the possibility of reducing the required necessary volume of contrast  using coronary intravascular ultrasound (IVUS). Patients were randomized to IVUS  guided angioplasty (n = 41) and angiography guided angioplasty (n = 42). IVUS-guided angioplasty requires a smaller volume of contrast (22.9 ± 12.5...
