Frank Laws

MD, FACC

Electrophysiologist & Interventional Cardiologist

Dr. Frank A. Laws is one of the few physicians in the United States who specializes in both interventional cardiology and electrophysiology. As a “hybrid” physician, Dr. Laws offers patients with both cardiac arrhythmias and obstructive coronary artery disease the most comprehensive care in the region. Dr. Laws completed his cardiology fellowship and his subspecialty fellowship in interventional cardiology at the University of Texas Houston Medical School. In 2001, while at the University of Texas he received a special commendation from the University of Texas board of regents for being the first American College of Cardiology (ACC) Merck Cardiology Research Fellow. As an assistant professor in clinical internal medicine at the University of South Carolina, he began an interventional cardiology program at the WJB Dorn VA Medical Center in Columbia, SC. While at WJB Dorn, he helped to pioneer a cardiac program without cardiovascular surgical back up. Dr. Laws was recruited in 2006 to Valley View to develop the Heart and Vascular program, including the Heart catheterization lab. Most recently, Dr. Laws embarked upon a secondary year-long fellowship in 2014 at a training program with the Tufts University School of Medicine to provide better care for patients with cardiac arrhythmias. His additional education has raised the level of expertise so that Valley View is now able to offer advanced cardiac services.

Kim M. Williams

MPH

Outcomes Researcher

Kim M. Williams, MPH tracks the effectiveness of arrhythmia care through the field of outcomes research. With honors, Kim received her bachelor of science from The University of Central Florida and later graduated summa cum laude from The Colorado School of Public Health with a Master’s of Public Health. Kim strongly believes the medical outcome should include the patients’ perspectives and desires. This belief is complemented by her analytic ability to assess registries, examine large data sets and improve the quality of healthcare delivery systems positions her to effectively facilitate the FixAfib platform. Kim has penned numerous peer reviewed publications and crafted the outcomes protocol to support our niche AFib program – The NEXUS Registry. This outcomes registry combines national cardiovascular data registries with long-term patient reported outcomes. Routinely, Kim submits peer reviewed scientific abstracts about our program, always monitoring the fiduciary use of health care dollars and, more importantly ensuring the patients’ values and preferences are heard. Outside of work she manages three boys, her husband Sam and two sons, Colton and Preston. Kim appreciates all things aesthetic and thought provoking, she finds the most beauty in the natural world.

Perfusionist

team

Nick Miller

LP, CCP, MSA, PhD

Perfusionist

Nicholas M. Miller, PhD, is a perfusionist at the Heart & Vascular Center at Valley View. As a cardiovascular perfusionist, Dr. Miller manages the physiological and metabolic needs of Valley View’s cardiac surgical patients, so that the surgeons of the Heart & Vascular Center may operate on a still, non-beating heart during certain procedures. Dr. Miller is responsible for the management of circulatory and respiratory functions of a patient, allowing Valley View’s cardiac surgeons to focus on the actual surgical procedure and less on the immediate needs of a patient. This is accomplished through the utilization of the heart–lung machine, as well as its associated components of an oxygenator, filters, reservoirs and tubing. He has multiple U.S. patents. He has the only patented vacuum venous assist cannulae in the U.S. and is currently working on a “bloodless cardiovascular circuit”, this uses pediatric technology on adult patients. This circuit minimizes the likelihood of patients requiring homologous banked blood.
