CVRTI: Basic Advances and Bench to Bedside Solutions
Over its 55 years, the CVRTI and cardiovascular research at The University of Utah have generated a storied history. From the Jarvik Heart (first implanted total artificial heart), to the identification of genetic and acquired Long QT syndrome, to the experiment and theory behind cardiac excitation which laid the theoretical groundwork for sophisticated cardiac electrical mapping and ablation today, the CVRTI has been on the forefront of basic discoveries which then make their way to patient care. These discoveries have had a powerful impact on advancing the treatment of cardiovascular disorders and improving the health of cardiac patients worldwide.
More recently, Dr. Stavros Drakos and his colleagues have advanced the concept that failing heart muscle is sufficiently dynamic to be recovered. Dr. Drakos, highlighted below, focuses on both understanding which cohort of patients with advanced heart failure have the potential to recover without a heart transplant and discovering the molecular recovery pathways so that much needed treatments can be developed.
Two programs are also underway that address major current unmet needs in cardiovascular medicine. CVRTI Investigators identified a protein, called GJA1-20k, that is an essential trafficking subunit for the formation of communication gap junction channels which allow heart cells to share electrical signals with each other. Patients with severe arrhythmia syndromes, such as genetic Arrhythmogenic Cardiomyopathy, have decreased amounts of GJA1-20k. CVRTI Scientists are teaming up with the biotechnology company Renovacor to develop GJA1-20k into a therapy for patients with several genetic subtypes of Arrhythmogenic Cardiomyopathy.
At the same time, CVRTI Investigators have taken on the challenge of addressing much needed muscle specific therapy for chronic heart failure. CVRTI Investigators have also discovered a protein called cardiac BIN1 (cBIN1), which is a membrane architectural protein that organizes the calcium handling machinery inside heart cells. Such machinery is responsible for our hearts’ ability to both contract and relax and is down regulated in most forms of chronic heart failure. Mouse studies have identified that replacing cBIN1 will improve heart contraction and relaxation, can rescue heart failure, and limit heart failure associated mortality. Our Investigators are now using preclinical models to explore how the protein can be administered safely in humans and are organizing the effort that should lead a clinical trial in the next five years.
Thank you for taking the time to explore the CVRTI. We are committed to understanding the biology of some of the most intractable cardiovascular problems, and to develop solutions for them.
New Wing Addition is Under Construction!
The CVRTI is expanding with the addition of a 10,000 sq. ft. new wing generously funded by the Nora Eccles Treadwell Foundation, University of Utah’s Senior Vice President of Health Sciences, Dr. Michael Good, and University of Utah’s President Taylor Randall. Construction began in May 2022 with an expected completion date of Spring 2023. The addition builds upon the strong growth of wet-bench research at the CVRTI and the University as a whole.
The design will consist of a new two-story building including wet lab space with additional PI and trainee offices, two kitchens, and a gathering space overlooking the Wasatch Mountains. The New Wing will also include a mothers’ room on the second floor and a 1,300 square foot freezer farm in the basement.

Representative Recent Publications
Over the past year, all of our investigators have published well. Some high impact work in cardiac metabolism and mitochondrial biology (Chaudhuri and Shaw), myocardial recovery (Drakos), and genetics (Tristani-Firouzi) are featured below.
The history and geographic distribution of a KCNQ1 atrial fibrillation risk allele
Hateley et. al., Nat. Commun., 2021, Tristani-Firouzi Lab
This first-of-its-kind study highlights the power of merging human genetics and human history in order to understand atrial fibrillation in a historical context. The collaborative effort between the University of Utah, Intermountain Cardiology, and AncestryDNA broadens our understanding of atrial fibrillation to include the history of our ancestral origins and population movement across time and continents.
Protective mitochondrial fission induced by stress-responsive protein GJA1-20k
Shimura et. al, eLife, 2021, Shaw Lab
After 30 years of research in ischemic-preconditioning, researchers have not been able to identify the central regulator. The Shaw Lab has now identified the long sought regulator of ischemic preconditioning which is a molecule we named GJA1-20k. They have found that this stress responsive molecule works with the actin cytoskeleton to split mitochondria in a protective fashion, protecting cells and larger organs against ischemic stress. This achievement also provides a novel therapeutic option to protect organs undergoing anticipated ischemia and stress-related injury.
Cardiac-specific deletion of voltage dependent anion channel 2 leads to dilated cardiomyopathy by altering calcium homeostasis
Shankar et. al., Nat. Commun., 2021, Drakos Lab
VDAC2 is a calcium channel present in the mitochondria of the cells of the heart. The Drakos Lab found that removing VDAC2 in mice hearts leads to heart failure by reducing the calcium uptake which led to impaired squeezing/pumping function of the heart. Re-introducing VDAC2 in these mice, resulted in improved squeezing/pumping function and overall cardiac health. Using a VDAC2 activator, efsevin, in mice with heart failure we observed significant improvement of these failing hearts. All of these findings show that VADC2 can be a novel therapeutic target to treat heart failure.
Mitochondrial calcium uniporter stabilization preserves energetic homeostasis during Complex I impairment
Balderas, et. al., Nat. Commun., 2022, Chaudhuri Lab
Inborn errors of metabolism affect about 1 in 5000 infants and are most commonly due to mutations in mitochondrial proteins. These children often suffer from heart failure, for which there are no approved therapies. In these diseases, the Chaudhuri Lab has identified a novel pathway that appears to compensate for mitochondrial dysfunction, involving a mitochondrial calcium channel. Because boosting this channel appears to prolong survival and improve function in animal models of these diseases, it may represent a novel therapeutic target.

Nora Eccles Treadwell Foundation and the Eccles Family:
55 Years of CVRTI support and growing
The CVRTI was the brainchild of the late, great hematologist, Dr. Max Wintrobe, who also served as the first CVRTI Director in 1967. Dr. Wintrobe spearheaded an effort for private funding to supplement federal support and he, along with prominent Utah businessman Robert S. Carter and Willard L. Eccles, created and directed the Cardiovascular Institute Foundation with the goal of raising $50,000/yr for five years. Among the numerous contributors were several members of the Eccles family including George S. Eccles, Marriner S. Eccles, and Spencer F. Eccles as well as Nora Eccles Harrison and her husband, Richard A. Harrison. This marked the beginning of the nearly 50 years of extraordinarily generous support of the CVRTI by Nora Eccles and the Nora Eccles Treadwell Foundation (NETF), created in 1962. Contributions to CVRTI from the NETF and the Eccles family have already amounted to over $60M and the NETF has recently reaffirmed its ongoing commitment to cardiovascular research with a $40M gift.

NETF funding includes support for numerous research and infrastructure grants, earlier construction of two research wings, current construction of a third additional wing, and major equipment purchases. Annual NETF grant funding includes support for the research programs of each individual CVRTI Investigator as well as the majority of our CVRTI operational expenses. The Board of Directors of the Nora Eccles Treadwell Foundation provides active and visionary leadership for the CVRTI and is currently composed of five members: Spencer F. Eccles (Chairman, nephew of Nora Eccles), Katie A. Eccles (Vice Chair, daughter of Spencer F. Eccles), Kathryn C. Econome, MD, Lawrence M. Harrison (Secretary, nephew of Richard A. Harrison), Robert M. Graham, and Kenneth W. Spitzer, PhD (former Director of CVRTI).
Nora Eccles recognized the importance of the CVRTI as a basic science institute, prioritizing fundamental and cutting-edge research. Our success is a testament to the dedication and vision of Nora Eccles and her foundation. There is a direct line from the NETF’s commitment to cardiovascular research at the CVRTI and the University of Utah, and improved knowledge and cardiac care that benefits patients in the United States and the world over.
