项目摘要
According to the American Heart Association cardiovascular disease affects 36.9% of the population, with approximately 30% of patients suffering from coronary artery disease. Acute Coronary Syndrome, associated with myocardial infarction, requires fast diagnosis and revascularization. Traditionally clinicians have chosen treatment methods by estimating the amount of flow going through the diseased coronary artery. Although several methods exist, catheter based pressure measurements are widespread among clinicians. Fractional flow reserve (FFR) is an index of the physiological significance of a coronary stenosis and is a measure of the maximal blood flow in a diseased artery to normal maximal flow. It is measured by comparing the pressure before and after the diseased arterial section, and thus indirectly estimating the loss of myocardial perfusion. Opsens has developed a FFR technology based on a photonic principle instead of the piezoelectric principle of the conventional technologies. This new photonic based technology has the potential to be more sensitive than current piezoelectric based technologies. Our partner is in the stage of evaluating the navigation and positioning precision of their technology (delivery in tortuous vessels and positioning at the stenotic site). We propose developing a dedicated dynamic phantom in-vitro model to study the navigation and positioning parameters and the associated hemodynamic disturbances associated with the technology.
根据美国心脏协会的数据,心血管疾病影响着36.9%的人口,其中约30%的患者患有冠状动脉疾病。急性冠脉综合征与心肌梗死相关,需要快速诊断和血运重建。传统上,临床医生通过估计流经病变冠状动脉的血流量来选择治疗方法。虽然有几种方法,但基于导管的压力测量在临床医生中很普遍。血流储备分数(FFR)是反映冠状动脉狭窄的生理意义的指标,也是衡量病变动脉最大血流量与正常最大血流量的指标。它是通过比较病变动脉段前后的压力来测量的,从而间接估计心肌灌注的损失。Opsens开发了一种基于光子原理的FFR技术,而不是传统技术的压电原理。这种基于光子的新技术有可能比目前的基于压电的技术更敏感。我们的合作伙伴正在评估他们技术的导航和定位精度(在曲折的船只上交付和在狭窄处定位)。我们建议开发一个专门的动态体模体外模型来研究导航和定位参数以及与该技术相关的血流动力学干扰。
