Latest lab news


The Visilble Heart Lab received an award from Dr. Robroy MacIver to support efforts related to the 3D Imaging of Congenital Hearts project. This project challenges us to: 1) image select cadaveric hearts from the Jesse Edwards Heart Registry; 2) coordinate local hospitals to obtain unique congenital images, then supply these hospitals with 3D images for patient and provider education; 3) create 3D printed hearts for U of MN professors, MDs, and nurses for instruction of students; and 4) create 3D printed hearts for patient families to support discussions of their childrens' heart defects.

The Lillehei Heart Institute awarded Dr. Paul Iaizzo an additional $50K to continue our efforts in youth education for 2016.

Paul Iaizzo received a $15K grant from the James B. Linsmayer Foundation to support research on "Development of 3D Human Torso Models." These models will be used to educate clinicians, students at all levels, and patients on cardiac anatomy and to provide computational models for virtual medical device prototyping and development.

Paul Iaizzo presented "From the Lab to the North Woods: MN Black Bear Research" at the Department of Surgery Brown Bag Luncheon series on November 6th, 2015.

Jamilisse Segarra received a travel award to participate in the 2015 Annual Biomedical Research Conference for Minority Students (ABRCMS) in Washington state (Nov. 11-14). She also received an Award in the Disciplines of Physics, Math, and Engineering for her poster "Effects of Laser-Cutting in Muscle Tissue Biomechanics."

Jamilisse Segarra's abstract "Effects of Laser-Cutting in Muscle Tissue Biomechanics" was accepted for a poster presentation at the Emerging Researchers National (ERN) Conference in STEM (Washington DC, February 25-27, 2016).

The manuscript "Isometric skeletal muscle force measurement in primary myopathies" was accepted for publication in Muscle & Nerve (DOI: 10.1002/mus.24954). Congrats to co-authors Hans Ginz, Paul Iaizzo, K Schweikert, and Will Durfee!

The manuscript "Visualization of catheter ablation for atrial fibrillation: impact of devices and anatomy" was accepted for publication in the World Journal of Cardiology. Congrats to co-authors Mark Benscoter and Paul Iaizzo!!

Jamilisse Segarra's abstract "Effects of laser-cutting in muscle tissue biomechanics" was selected for presentation at the 2015 Annual Biomedical Research Conference for Minority Student (ABRCMS). This conference will be held at the Washington State Convention Center in Seattle (Nov. 11-14, 2015).

Kathryn Thomas presented her research poster at the CTSI Fall Scholar and Mentor Reception on September 17th, and was recognized with a travel award of $1,500 to present her research at an upcoming national conference. These awards were distributed to the top posters based on presenter translation plans, including next steps, barriers to translation, and how the
project will contribute to improving human health.

Megan Schmidt successfully passed her oral preliminary exams on September 11th (OPE title: Utility of Monophasic Action Potentials as a Means of Monitoring Electrophysiologic Function during the Diagnosis and Treatment of Cardiac Arrhythmias).

Lars Mattison presented a research poster at the 1st World Congress of Electroporation in Slovenia (September 6-10, 2015).

Stephen Quallich successfully defended his PhD thesis "Studies of Ablation Complications During the Treatment of Atrial Fibrillation" on September 1st.

Former graduate student Alex Hill (PhD, 2003) was recognized as a 2015 Bakken Fellow for his achivements and key contributions to Medtronic.

Lars Mattison successfully passed his oral preliminary exams on August 26th (OPE title: Ablation of Cardiothoracic TIssues: Threshold of Therapy vs. Collateral Cell Damage).

The manuscript "Direct visualization of an iatrogenic septal defect in a reanimated human heart" will be published in Heart Rhythm Case Reports. Co-authors are Steve Howard, Ryan Goff, David Benditt, and Paul Iaizzo.

The manuscript "Assessing the relative integrity of formed cardiac linear lesions by recording both focal monophasic action potentials and contact forces: a technical brief" will be published in the Journal of Translational Engineering in Health & Medicine (IEEE). Co-authors include Mark Benscoter and Paul Iaizzo.

Co-authors Mark Ditmer, John Vincent, Leland Werden, Paul Iaizzo, Dave Garshelis, and John Fieberg published a manuscript in Current Biology entitled "Bears show a physiological but limited behavioral response to unmanned aerial vehicles." DOI: 10.1016/j.cub.2015.07.024.

Our two LSSURP students presented posters on their summer research projects on August 6th at McNamara Alumni Center, including 1) Jamilisse Segarra-Villafane: Effects of laser-cutting in muscle tissue biomechanics; and 2) Jason Kelly: Highlighting coronary vasculature of perfusion-fixed hearts using magnetic resonance imaging.

LHI Scholars presented posters summarizing their summer research projects on July 29th, including 1) Lizzy Laakso: Comparison of the anatomical changes of swine hearts in situ and in vitro with echocardiography; and 2) Emily Syverud: Improving MRI scans of perfusion-fixed en bloc heart lung specimens.

Paul Iaizzo presented "Innovation on the Edge: from reanimated human hearts to hibernating black bears" at the Association of Medical Illustrators annual conference (AMI 2015) hosted by the Cleveland Clinic on Friday, July 24th.

CONGRATULATIONS to Stephen Quallich who started his new job at Medtronic in June as a Senior Reliability Engineer.
