Anisotropic Mass-Spring Method Accurately Simulates Mitral Valve Closure from Image-Based Models
Hammer, Peter; Del Nido, Pedro J.; Howe, Robert D. (Springer Science + Business Media, 2011)Heart valves are functionally complex, making surgical repair difficult. Simulation-based surgical planning could facilitate repair, but current finite element studies are prohibitively slow for rapid, clinically-oriented ... -
Fast Image-Based Model of Mitral Valve Closure for Surgical Planning
Hammer, Peter E.; Vasilyev, Nikolay V.; Perrin, Douglas P.; Del Nido, Pedro J.; Howe, Robert D. (MIDAS, 2008)Surgical repair of the mitral valve results in better outcomes than valve replacement, yet diseased valves are often replaced due to the technical difficulty of the repair process. A surgical planning system based ... -
Fast Interactive Simulations of Mitral Valve Repair
Tenenholtz, Neil Arturo; Hammer, Peter; Howe, Robert D. (2012) -
Mass-Spring Model for Simulation of Heart Valve Tissue Mechanical Behavior
Hammer, Peter; Sacks, Michael S.; Del Nido, Pedro J.; Howe, Robert D. (Springer Nature, 2011)Heart valves are functionally complex, making surgical repair difficult. Simulation-based surgical planning could facilitate repair, but current finite element (FE) studies are prohibitively slow for rapid, clinically ... -
On the design of an interactive, patient-specific surgical simulator for mitral valve repair
Tenenholtz, Neil Arturo; Hammer, Peter; Schneider, Robert J.; Vasilyev, Nikolay; Howe, Robert D. (IEEE, 2011)Surgical repair of the mitral valve is a difficult procedure that is often avoided in favor of less effective valve replacement because of the associated technical challenges facing non-expert surgeons. In the interest of ... -
Reduction and Redistribution of Gap and Adherens Junction Proteins After Ischemia and Reperfusion
Tansey, Erin E.; Kwaku, Kevin F.; Hammer, Peter; Cowan, Douglas Burr; Federman, Micheline; Levitsky, Sidney; McCully, James Donald (Elsevier BV, 2006)Background Previous studies have demonstrated that alterations in myocardial structure, consistent with tissue and sarcomere disruption as well as myofibril dissociation, occur after myocardial ischemia and reperfusion. ... -
Superparamagnetic Iron Oxide Nanoparticles Function as a Long-Term, Multi-Modal Imaging Label for Non-Invasive Tracking of Implanted Progenitor Cells
Pacak, Christina A.; Hammer, Peter E.; MacKay, Allison A.; Dowd, Rory P.; Wang, Kai-Roy; Masuzawa, Akihiro; Sill, Bjoern; McCully, James D.; Cowan, Douglas B. (Public Library of Science, 2014)The purpose of this study was to determine the ability of superparamagnetic iron oxide (SPIO) nanoparticles to function as a long-term tracking label for multi-modal imaging of implanted engineered tissues containing ...
