TORONTO, Oct. 28, 2024 (GLOBE NEWSWIRE) -- Conavi Medical Corp. (TSXV: CNVI) (“Conavi Medical”), a commercial stage company focused on designing, manufacturing, and marketing imaging technologies to guide common minimally invasive cardiovascular procedures, is pleased to announce that the peer-reviewed Journal of the American College of Cardiology: Cardiovascular Interventions has published an article by Tufaro et al. which provides an overview of recent developments in hybrid intracoronary imaging and discusses its potential value in different clinical and research areas, such as percutaneous coronary intervention (“PCI”) guidance, vulnerable plaque detection, and the assessment of focal and systemic therapies targeting atherosclerosis.

Quoting directly from the full article:

“Several studies have shown that specific morphologic features observed on intravascular imaging post-PCI are associated with a high risk of stent failure. Stent underexpansion constitutes the most common cause of stent failure; large edge dissection and plaque at the edge of the stent have been associated with stent edge–related events, whereas tissue or thrombus protrusion in stented segments was found to be a predictor of restenosis and stent thrombosis. Finally, the presence of uncovered or malapposed struts has been associated with an increased risk of stent thrombosis in large registries of patients who had [optical coherence tomography (“OCT”)] imaging at the time of the event, but prospective OCT imaging studies have provided conflicting results; therefore, the role of these features on stent failure remains elusive

Combined [intravascular ultrasound (“IVUS”)] OCT imaging has theoretical advantages over standalone imaging in assessing post-PCI results; IVUS can minimize the risk of stent underexpansion and assess [plaque burden] at the edge of the stent, whereas OCT can detect more accurately edge dissections, the presence of lipid at the reference segments, malappositions, and tissue protrusion. This hypothesis is supported by a recent prospective observational study of 17 patients who underwent elective PCI using the Novasight Hybrid IVUS OCT system [Conavi Medical]. IVUS OCT imaging was performed successfully in 10 patients post–stent implantation. Compared to IVUS, OCT more often identified the presence of incomplete strut apposition (8.0% vs 0.8%; P < 0.001) and tissue protrusion (50.6% vs 15.9%; P < 0.001), but IVUS detected stent underexpansion more often than OCT (28.7% vs 23.1%; P ¼ 0.039). These promising findings are expected to provide the substrate for the conduction of larger studies that will allow us to draw safe conclusions about the superiority of IVUS OCT over standalone intravascular imaging.”
