BCH introduces newest technology to treat AFib & prevent stroke risk

First patient in the Boulder & Denver metro area successfully implanted with the FDA-approved WATCHMAN FLX™ PRO Device at Foothills Hospital

Last week, Boulder Community Health (BCH)’s Foothills Hospital became the first hospital in Colorado (full market release) to offer patients the newest technology to treat non-valvular atrial fibrillation. Experienced interventional cardiologist Srinivas Iyengar, MD and his Structural Heart & Valve team performed the milestone procedure and successfully implanted the WATCHMAN FLX™ Pro Left Atrial Appendage Closure (LAAC) Device.

Dr. Iyengar – Boulder Heart’s Director of Structural Heart & Interventional Cardiology with a 100% WATCHMAN success rate – is offering the latest LAAC technology that is designed to reduce stroke risk and serve as an alternative to the lifelong use of blood thinners for people with atrial fibrillation not caused by a heart valve problem (also known as non-valvular AF or NVAF).

The newest WATCHMAN FLX Pro has an updated design with three new features to advance performance and safety and ensure the best long-term outcomes. These features include a permanent device coating to promote faster healing time, an additional device size to treat the widest range of anatomies, and visualization markers to position and anchor the device with an enhanced level of accuracy.

“I’m very proud to have performed one of the 1st implants of the WATCHMAN FLX Pro in Colorado at our facility, Foothills Hospital,” says Dr. Iyengar. “This latest-generation WATCHMAN device offers my patients a potentially life-changing stroke risk treatment and will allow us to treat a broad range of patients thanks to the expanded size matrix.”

February is Heart Month, which serves as a timely reminder of the increased risk of stroke among people living with atrial fibrillation (AFIB). The WATCHMAN technology, which has been implanted in more than 300,000 patients worldwide, closes off an area of the heart called the left atrial appendage (LAA) to keep harmful blood clots that can form in the LAA from entering the blood stream and potentially causing a stroke. By closing off the LAA, the risk of stroke may be reduced, and, over time, patients may be able to stop oral anticoagulation therapy.

BCH's patient who received the new WATCHMAN FLX Pro is one of an estimated seven million Americans who are affected by AF - an irregular heartbeat that can feel like a quivering heart. The WATCHMAN is the only FDA-approved implant proven to reduce stroke risk in those with AFIB that is not caused by a heart valve problem. Learn more here.
