The team, also consisting of BTB graduates Damaris Pasca and Arnab Roy and second-year medical student Jalal Jwayyed, set their sights on atrial fibrillation, more commonly known as AFib, the most commonly diagnosed arrythmia, which causes symptoms such as heart palpitations, stroke and in the most severe cases, heart failure. Approximately 450,000 individuals are hospitalized each year in the U.S. with AFib as the primary diagnosis, with 12.1 million Americans expected to be diagnosed with AFib by 2030.
The team narrowed their focus to the fact that patients with AFib are five times more likely to have a stroke as a result of stagnant blood clotting and exiting the heart. Left atrial appendage occlusion (LAAO) is a promising second-line therapy to minimize stroke risk in AFib patients, especially for those who are unable to tolerate oral anticoagulants or are at an increased risk for bleeding. In this interventional procedure, the left atrial appendage of the heart is physically occluded by an implantable device, preventing thrombus formation and migration from the appendage. However, peri-device leakage and device related thrombus (DRT) are common limitations of LAAO.
To address this issue, the team came up with a novel technique for coating LAAO devices called “Zonal Coating Application System (ZCAS).” ZCAS minimizes peri-device leakage by integrating a two-part thromboresistant and endothelialization-promoting coating onto the device. The end result of the ZCAS is an improved LAAO device that ensures a complete endothelial seal of the left atrial appendage.
Under the guidance of Fayez Safadi, Ph.D., professor of anatomy and neurobiology, the team is working towards getting the device on the market. In Dr. Safadi’s lab, the team developed a novel in-vitro model of LAAO device endothelialization, which they used to validate their ZCAS concept. They presented at the 2024 NEOvations Bench to Bedside Competition, getting feedback from other bioinnovators and investors. The team will be presenting its device at Bench to Bedside as a legacy team in 2025 as they prepare to show the progress they have made in the past year.
Preparing for the Needs of Tomorrow’s Workforce
The health care workforce is in a constant state of evolution. As populations and technology change, future physicians like Muskara will need more than diagnostic skills to thrive.
NEOMED’s College of Graduate Studies is well-prepared to adjust to these shifts. The College continues to grow with programs like BTB that meet the demands of the health care workforce, developing innovative new programs to prepare students for a new world of health care.
