Spotlight on the Technology in the West Hills Heart & Vascular Institute

The technology available for cardiovascular care has evolved greatly over the past decade, and West Hills Hospital has worked to invest in the most advanced technologies available so that patients have immediate access to the right care. Our Heart & Vascular Institute is a chest pain receiving center and official STEMI receiving center, though our primary specialty is in treating arrhythmias, or malfunctioning of the heart’s electrical system. You can watch this video clip to hear from Dr. James Ong, who is a cardiac electrophysiologist on our cardiovascular team. Below, you’ll get a closer look at some of the technologies he discusses in this short clip.


The field of electrophysiology focuses on regulating the heartbeat of patients suffering from arrhythmias such as atrial fibrillation. In this area, there are two primary goals for treatment. The first is to relieve symptoms and regulate the heart’s rhythm. This is often achieved through device placement, which may include remote monitoring for direct communication with your electrophysiologist. The second goal in treatment is minimizing stroke risk, and this may be accomplished either through the use of medication or with radiofrequency ablation.

Radiofrequency ablation

During radiofrequency ablation, your doctor will use a catheter to find areas of the heart that are fibrillating, or beating too fast, and burn those areas away with radio energy. This type of minimally invasive procedure can be life-changing, since it can permanently improve the function of the heart and significantly reduce stroke risk.

3-D computer modeling

In any procedure performed at West Hills Hospital, physicians have the benefit of 3-D imaging to produce a clear model of the heart, which will pinpoint areas with abnormalities resulting in arrhythmias. Dr. Ong likens this technology to the GPS system in a car, since it allows for the accurate navigation of a catheter through the heart for precise treatment.
