UA Sarver Heart Center Expert Offers Insights into New Uses of a Surgical Adhesive in New England Journal of Medicine Review


Dr. Slepian and Danny Bluestein, PhD, professor of bioengineering at Stony Brook University in New York, co-authored a review article in the New England Journal of Medicine (April 17, 2014), citing the benefits of hydrophobic light-activated adhesive (HLAA), a fluid, blood-resistant tissue glue that can be applied as a liquid before a procedure is performed and activated on demand to adhere, cure and bond.

CardioBuzz: A New Vascular Glue?


The UV light-activated adhesive created a water-tight seal in seconds that stayed intact in the face of high pressure and flowing blood but biodegrades over time, explained Danny Bluestein, PhD, of New York's Stony Brook University, and Marvin J. Slepian, MD, of the Sarver Heart Center in Tucson, Ariz.

UA Researchers Aim to Rid Pacemakers of Batteries


Researchers at the University of Arizona are working on a new way to power pacemakers that could do away with batteries for good.

Beating Heart Powers Pacemaker


Marvin H. Slepian, MD, a cardiologist at the University of Arizona Sarver Heart Center, and his colleagues are part of an interdisciplinary research team, including scientists from Northwestern University and the University of Illinois, who are developing a flexible medical implant that harvests the energy of the beating heart. Such a device could power pacemakers, defibrillators and heart-rate monitors naturally and reliably and reduce or eliminate the need for batteries.

TOPCAT Trial Tests Possible Treatment for Patients with Heart Failure and Preserved Heart Pump Function


Nancy K. Sweitzer, MD, PhD, director of the University of Arizona Sarver Heart Center and chief of the Division of Cardiology at the UA College of Medicine – Tucson serves on the TOPCAT executive committee.

New hope for helping your heart


Nancy K. Sweitzer, MD, PhD, is among the heart experts providing an update on heart disease-related medications and technology.

Sarver Leader Discusses Clinical Trials


Dr. Nancy Sweitzer, a cardiologist and physiologist recognized for her leadership and experience in clinical heart disease research, focused on her specialty of clinical trials in treating heart disease.

Local Medical Tech Co Testing New Devices for Artificial Hearts


A local company takes action by testing two new devices in clinical trials to make changes to artificial hearts in the future to come.

New Tech Uses Patient's Body to Power Pacemakers


One of the difficulties with pacemakers is the battery life. Marvin Slepian has looked to move away from using batteries to instead, a source called piso electronics.

Endowed Chair Fulfills Dream of Congenital Heart Disease Program for Adults


A generation ago, adult cardiologists had little need to study congenital heart disease. Few children born with these heart conditions lived to adult age. Great advances have been made during the past few decades in caring for children with major structural heart issues (congenital heart diseases), allowing survival to adulthood and a productive life. Today, more adults are living with congenital heart disease than children with these conditions. This endowed chair provides an opportunity to make important strides toward fulfilling a dream of building a comprehensive adult congenital cardiology program for southern Arizona.
