    Collapse Overview
    Dr. Matthews was recruited to the University of Southern California faculty in 2007 to direct the Department of Interventional Cardiology. He brings 20 years of experience in high-level tertiary interventional cardiology to the institution. Dr. Matthews has emerged as a leader in the advancement of percutaneous treatment of peripheral vascular disease.

    He remains very active in the clinical investigation and use of new devices and techniques for the treatment of coronary artery disease and carotid artery disease. In addition, Dr. Matthews was among the first in Los Angeles to percutaneously close structural cardiac defects, such as atrial septal defect and to patent foreman ovale. Dr. Matthews previously served as head of an interventional cardiology training program that trained over 50 interventional cardiologists, many have gone on to successful careers all over the world.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
