• Assessment of Advanced Magnetic Resonance Imaging in Heart Rochester, Minn.

  The purpose of this study is to continue the evaluation of non-FDA approved MR equipment software and hardware for imaging the heart and associated vasculature.

• Coronary CTA for Radiation Therapy Planning in Lymphoma Patients Rochester, Minn.

  Our purpose for this study is to help design a therapy plan that can decrease extra radiation exposure to your heart during radiotherapy. The therapy plan will use images obtained using a dual-source CT scanner

• CT Evaluation of Left Ventricular Assist Devices Rochester, Minn.

  The purpose of this study is to measure the performance of Dual-Energy CT scans that are able to reduce interference caused by metal objects, and then compare with standard echocardiography for checking patients with LVAD devices.

• HCMR - Novel Markers of Prognosis in Hypertrophic Cardiomyopathy (HCMR) Rochester, Minn.

  The purpose of this study is to use data mining methods to identify demographic, clinical, and new CMR, genetic and biomarker variables to then develop a predictive risk assessment model to score a patient's combination of factors for HCM, and establish the evidence base to later enable clinical trial design to reduce the morbidity and mortality of HCM in a cost-effective manner.

• Remodeling of the Mitral Annulus following Robotic-Assisted Surgical Mitral Valve Repair: Potential Role of ECG-gated CT of the Heart Rochester, Minn.

  The purpose of this study is to investigate post-operative changes in cardiac structure and function for patients with mitral regurgitation to define heart remodeling.
