West Hills Hospital & Medical Center Ranked No. 1 in Los Angeles County for Door-to-Balloon Time

January 18, 2018 – West Hills Hospital & Medical Center, a full-service acute care facility, announces the first completion of the Tryton Side Branch Stent in the San Fernando Valley. This unique stent is engineered to treat coronary bifurcation lesions involving large side branches.

Coronary artery disease — the leading cause of death in the United States for both men and women — often results in the buildup of plaque at an artery branch, known as a bifurcation. Provisional stenting on the main branch only is the current standard care for approximately 20 to 30 percent of these cardiac patients. In these instances, the side branch does not have a stent, leaving the patient vulnerable to greater complications.

The stent provides complete lesion coverage and more predictable outcomes for patients who would otherwise need open-heart surgery or multi-stent procedures requiring large access sites and catheters.

“We are excited to be the first hospital in the greater San Fernando Valley to offer and utilize this new technology,” said Aamer Jamali, M.D., interventional cardiologist at West Hills Hospital. “The Tryton Side Branch Stent is the first stent specifically designed for bifurcation lesions and provides us with a new way to treat high-risk patients. The stent allows us to perform less invasive surgeries, and we’re looking forward to letting the community know that this new technology is available to them.”

West Hills Hospital was recently ranked number one in Los Angeles County for “Door-to-Balloon Time,” — the amount of time between a heart attack patient’s arrival at the hospital and the time blood flow is re-established. Standard guidelines recommend that hospitals meet a 90-minute goal and West Hills Hospital currently averages 46 minutes, almost half of the national average.

(D) OCT cross-sectional (top) and longitudinal (bottom) images acquired post-IVL and coregistered to the OCT lens (white arrow in C) demonstrate multiple calcium fractures and large acute luminal gain. (E) Angiography demonstrates complete stent expansion with the semicompliant stent balloon (inset) without the need for high-pressure noncompliant balloon inflation. (F) OCT cross-sectional (top) and longitudinal (bottom) images acquired post-stenting and coregistered to the OCT lens (arrow in E) demonstrate further fracture displacement (arrow), with additional increase in the acute area gain (5.17 mm2), resulting in full stent expansion and minimal malapposition.
