Cardiology, Cardiac Examinations, Echocardiograms, ECG, Non-invasive & Invasive Surgeries

Meg Sleeper VMD graduated cum laude from the veterinary school of the University of Pennsylvania in 1993. Following an internship in private practice, she returned to the University of Pennsylvania for a residency in cardiology, which was completed in 1997. Since that time, with the exception of 1 year in private practice she has worked in the section of cardiology and has been section chief of cardiology since 2001. In 2008 she was promoted to associate professor of cardiology-clinician educator track.

Her research initially focused on the identification and characterization of juvenile dilated cardiomyopathy in Portuguese water dogs and has led to several ongoing studies, including most recently the evaluation of various candidate genes for use in a therapeutic gene transfer approach to improve cardiac function in failing hearts. Ultimately the goal is to translate this work to gene transfer treatment approaches for canine idiopathic dilated cardiomyopathy and human heart failure. Studies are also underway evaluating therapeutic gene transfer approaches to treat cardiac and skeletal muscle dysfunction in X-linked muscular dystrophy golden retriever dogs.

Keywords: dilated cardiomyopathy, therapeutic gene transfer, non-human primate cardiology, heart failure
