A microsurgical and equipment training program for cardiovascular researchers focused on collecting pressure-volume loops and creating cardiac disease models such as MI and TAC in rodents.
This workshop is designed for scientists who want to develop and hone their microsurgery skills while learning about advanced applications and measurements of hemodynamics and cardiovascular function in rodent models. The laboratory training component is supplemented with course material delivered by webinar – this ensures registrants are adequately prepared for lab training modules and maximizes hands-on time in the lab.
Course attendees will gain in-depth experience using catheter-tipped pressure transducers and pressure-volume catheters as the primary means of studying cardiac performance in both open and closed-chest models. Attendees will learn how to monitor and analyze baseline hemodynamic data as well as advanced PV loop indices of function including preload, afterload, contractility, lusitropy, and heart-vasculature interactions. Attendees also have the option of learning how to acquire and analyze right ventricular PV loops. The course focuses on survival models of cardiac dysfunction including myocardial infarction and aortic banding. Course topics include how to create models of disease consistently and the associated methods for studying changes in function.
Laboratory equipment for this course has been graciously supplied by the following companies:

Dr. Timothy A. Hacker, PhD
Dr. Hacker is a Senior Scientist and Director of the Cardiovascular Physiology and Surgery Core Facility at the University of Wisconsin-Madison. Dr. Hacker has established cardiac disease models in mice, rats, rabbits, pigs, dogs and primates. His lab documented the variability in mouse coronary anatomy and was the first lab to publish right ventricular pressure-volume data in mice.
Mr. Gaoussou Diarra, MS
Gaoussou Diarra is an associate researcher at the University of Wisconsin-Madison and the Cardiovascular Physiology and Surgery Core Facility. Mr. Diarra has over 15 years of surgical experience in species ranging from mosquitos to rats. He now specializes in rodent microsurgery, in particular, myocardial infarctions, pulmonary and aortic banding, implantable telemetry devices and catheter-based hemodynamic recordings. Although a native of Mali, 25 years of residence in Wisconsin has turned him into a “cheese-head”!
Ms. Allison Brodbeck, BA
Allison Brodbeck is an assistant researcher in the Cardiovascular Physiology and Surgery Core Facility. Ms. Brodbeck has worked with species ranging from mice and rats to pigs and dogs, even exotic species including cetaceans and pinnipeds. Her work at the Core Lab primarily focuses on quantifying cardiovascular surgical models with noninvasive imaging, including echocardiograms, laser Doppler, bioluminescence imaging and fluorescence imaging. Allison is also instrumental in project management, animal surgery and data analysis.
