The Cardiology Bioengineering Laboratory, located in the Johns Hopkins Hospital, focuses on the applications of advanced imaging techniques for arrhythmia management. The primary limitation of current fluoroscopy-guided techniques for ablation of cardiac arrhythmia is the inability to visualize soft tissues and 3-dimensional anatomic relationships.
Implementation of alternative advanced modalities has the potential to improve complex ablation procedures by guiding catheter placement, visualizing abnormal scar tissue, reducing procedural time devoted to mapping, and eliminating patient and operator exposure to radiation.
Active projects include
• Physiological differences between isolated hearts in ventricular fibrillation and pulseless electrical activity
• Successful ablation sites in ischemic ventricular tachycardia in a porcine model and the correlation to magnetic resonance imaging (MRI)
• MRI-guided radiofrequency ablation of canine atrial fibrillation, and ...diagnosis and intervention for arrhythmias
• Physiological and metabolic effects of interruptions in chest compressions during cardiopulmonary resuscitation
Henry Halperin, MD, is co-director of the Johns Hopkins Imaging Institute of Excellence and a
professor of medicine, radiology and biomedical engineering. Menekhem M. Zviman, PhD is the laboratory manager.
The Center for Bioengineering Innovation and Design educates and develops the next generation of leaders in health care technology innovation. CBID creates and develops solutions for major challenges to human health around the world. Our key measure of success is the positive impact of our students and their solutions on the quality and accessibility of health care worldwide.
Daniel Kuespert Lab
The Daniel Kuespert Lab conducts research on a range of topics within bioengineering. Past studies include exploring microscale behavior in amphiphilic fluid mixtures predicted by the SAFT equation as well as local order and microphase formation in fluids containing asymmetric molecules.
Interventional Cardiology Research Group
Our group is interested in a broad array of clinical and translational investigations spanning the evaluation of basic pathophysiology in patients undergoing cardiac procedures, development and evaluation of new therapeutic strategies, and improving patient selection and outcomes following interventional procedures. We are comprised of a core group of faculty and dedicated research nurses as well as fellows, residents, and students. Projects range from investigator-initiated single-center observational studies to industry-sponsored multicenter phase 3 randomized controlled trials. We have established a database of all patients who have undergone TAVR at Johns Hopkins, which is providing the basis for several retrospective analyses and will serve as the foundation for future studies of TAVR. We are also engaged in collaborative projects with other groups from the Department of Medicine and other Departments including Cardiac Surgery, Anesthesiology, Radiology, Psychiatry, and Biomedical... Engineering. Members of our group are actively involved with the Johns Hopkins Center for Bioengineering Innovation and Design (CBID) in the development of novel minimally-invasive cardiovascular devices. view less
