AVENTUSOFT L.L.C — Department of Health and Human Services SBIR Phase I: 200

Description

PROJECT SUMMARY ABSTRACT This SBIR Phase I project will develop an innovative medical device useful for rapid automated characterization of myocardial performance in diabetes patients Left ventricular systolic and diastolic myocardial impairment is the most common manifestation and the systolic function is monitored with left ventricular ejection fraction measurement and the diastolic function is monitored with left ventricular filling pressure These two measurements are available after reading and analyzing the echocardiographic examinations The reported incidence of systolic dysfunction is approximately and diastolic dysfunction is approximately in diabetes patients without known heart disease Even though the development of cardiovascular disease is the most common complication of type diabetes echocardiography is not routinely performed in patients with type diabetes Thus the cardiologist and patients care provider need to collaborate to identify new non invasive techniques to detect cardiac dysfunction at an early and potentially reversible stage before the onset of the clinical signs and symptoms The ability to use a device in any patient care setting by any healthcare professional without the special requirement of an echocardiogram would be of significant value Towards this goal of early identification of cardiac dysfunction AventuSoft is developing a novel portable medical device HemoTag to provide measurement of systolic function using heart sounds Through this SBIR project we will develop technology to include the rapid and automated measurement of diastolic function without requiring an echocardiogram During this Phase I SBIR the AventuSoft team will complete validation studies with diabetes patients to demonstrate a major clinical advancement by enabling the automated characterization of myocardial performance using HemoTag At a fraction of the size and cost of current products HemoTag can enable reliable accurate and easy to use application by healthcare professionals for the measurement of myocardial systolic and diastolic performance It overcomes the limitations of cost size and skilled personnel requirements of existing echocardiography devices Phase II activities will focus on larger multi center clinical studies enhancing the technology for early detection verification and validation testing requirements necessary for the FDA k premarket notification and on productizing the system for commercial use The benefit of this pioneering work is the development of a low cost and portable device that will have great potential for early detection diagnosis and quantification of cardiovascular disease and cardiomyopathy complications in diabetes HemoTag can help address the significant problems of patient safety though advancements in imaging equipment make it more accessible and readily available as the technology does not require skilled specially trained operators PROJECT NARRATIVE Overall this project provides direct relevance to public health by facilitating new insights through the development of an innovative medical device useful for rapid automated characterization of myocardial performance in diabetes patients The novel biologically inspired device will significantly impact the current known methods for detection monitoring prevention and treatment of systolic and diastolic dysfunction and support evidence based clinical practice The device will have great potential in the early diagnosis of left ventricular dysfunction not only as result of type diabetes but for many other etiologies as well
