Validating Cardiac MRI Biomarkers and Genotype-Phenotype Correlations for DMD

One objective of this project is to define the precision and reproducibility of several diagnostic cardiac MRI biomarkers obtained during a fast, free-breathing cardiac MRI exam. This will enable the team to bridge the significant multi-year diagnostic gap between early genotyping and the late onset of overt cardiac symptoms. A second objective is to define the cardiac-specific genotype-phenotype correlation via outlier analysis.

A New Framework for Understanding the Mechanisms of Diastolic Dysfunction

The objective of this project is to use an Equilibrium-Material-Stability (EMS) framework that couples patient-specific clinical MRI and LV pressure data in a computational model of the heart to diagnose changes in diastolic myocardial stiffness. The central hypothesis is that the new EMS framework for understanding the mechanisms of diastolic dysfunction in HFpEF will be more sensitive and outperform currently available approaches.

The Cardiac Connectome for Understanding the Electromechanics of Heart Failure

The goal of this study is to develop whole-heart multi-modal imaging of cardiac microstructural connectivity and to quantitatively characterize the whole-heart cardiac connectome.

NIH/NIBIB/U01 (PI Vasanawala, Co-I Ennis, EB029427)                        08.01.2020 to 07.31.2021

Enabling the Next Generation of High Performance Pediatric Whole-Body MR Imaging

The major goal of this project is to create and validate the next generation systems for pediatric MRI.

NIH/NIBIB/R01 (PI Hargreaves, Co-I Ennis, EB009055)                          03.01.2020 to 11.30.2023

High Resolution Whole-Breast MRI at 3.0T

This research will develop much higher resolution breast MRI, allowing better classification of small lesions to prevent unnecessary biopsy and detect cancer earlier.

NIH/NHLBI/R01 (PI Woo, Co-I Ennis, HL152155)                                 05.05.2020 to 04.30.2024

Biomechanical Optimization of Cardiac Valve Repair Operations

The objective of this project is to validate our findings using large animal cardiac surgery models, and then hopefully translate these discoveries directly to the operating room in the human clinical arena.

NIH/NHLBI/R01 (PI Ennis, HL152256)                                                06.24.2020 to 05.31.2024

Using Atrial Mechanics to Identify Fibrosis in Patients with Atrial Fibrillation

We propose to use magnetic resonance imaging (MRI) of atrial mechanics to identify localized fibrosis and hypothesize that attenuated mechanics provide a robust measure of atrial fibrosis.
