Miniature Heart Sensor Keeps Heart Failure Patients Out of the Hospital
Tiny microchip inside heart can monitor vitals of advanced heart failure patients remotely before heart failure symptoms strike.
Cardiologists at The Mount Sinai Hospital have begun implanting tiny, state-of-the-art microchip sensors in patients with advanced heart failure to better monitor symptoms and reduce their chances of returning to the hospital.
The implantable sensor, called the CardioMEMS™ HF System, developed by St. Jude Medical, is a battery-less, dime-sized device placed directly inside the heart to monitor its pulmonary artery. Implanted through a minimally invasive procedure, the sensor detects increases in pulmonary artery pressure, an early sign of worsening heart failure that can be detected before symptoms arise. Among the symptoms of advanced heart failure is shortness of breath, the kind of frightening experience that sends people racing to emergency rooms.
Once implanted, the device transmits daily pressure readings to a patient's medical team, who can then proactively provide real-time, personalized feedback before symptoms worsen. The device has been shown in clinical trials to reduce hospital readmissions for advanced heart failure patients by up to 37 percent.
The new microchip technology is designed for advanced heart failure patients who have been hospitalized within the previous 12 months. The goal of Mount Sinai's heart failure experts is to improve the quality of life in patients with heart failure and reduce the likelihood of hospital readmissions, a growing trend for this high-risk patient population which has become a national priority for the Centers for Medicare and Medicaid Services to reduce readmissions to curb growing healthcare costs.
"This new device will enable heart failure patients to live more comfortably, easing their worries as we closely monitor them for the earliest signs of fluid retention, a major cause of the symptoms of breathlessness and tiredness heart failure patients experience," says Raymond Bietry, MD, Assistant Professor of Cardiology who was the first cardiologist at Mount Sinai to implant the device.
The sensor is the first of its kind and was FDA-approved in 2014. Research studies have shown it has the ability to successfully and safely transmit daily measurements from the patient to their doctor. The implant procedure takes less than an hour to perform, there is typically no overnight stay, and patients can quickly resume their normal life.
"Mount Sinai is all about increasing patient care, comfort, and quality of life with the use of innovative medicine," said Sean Pinney, MD, Director of Heart Failure and Transplantation for The Mount Sinai Hospital and the Mount Sinai Heath System. "This new sensor technology may be a real game-changer for the field of heart failure and allows us to improve patient care, long after they've left the doors of Mount Sinai."
About the Mount Sinai Health System
The Mount Sinai Health System is New York City's largest integrated delivery system encompassing (with the addition of South Nassau Communities Hospital) eight hospital campuses, a leading medical school, and a vast network of ambulatory practices throughout the greater New York region. Mount Sinai's vision is to produce the safest care, the highest quality, the highest satisfaction, the best access and the best value of any health system in the nation. The Health System includes approximately 7,480 primary and specialty care physicians; 11 joint-venture ambulatory surgery centers; more than 410 ambulatory practices throughout the five boroughs of New York City, Westchester, Long Island, and Florida; and 31 affiliated community health centers. The Icahn School of Medicine is one of three medical schools that have earned distinction by multiple indicators: ranked in the top 20 by U.S. News & World Report's "Best Medical Schools", aligned with a U.S. News & World Report's "Honor Roll" Hospital, No. 12 in the nation for National Institutes of Health funding, and among the top 10 most innovative research institutions as ranked by the journal Nature in its Nature Innovation Index. This reflects a special level of excellence in education, clinical practice, and research. The Mount Sinai Hospital is ranked No. 18 on U.S. News & World Report's "Honor Roll" of top U.S. hospitals; it is one of the nation's top 20 hospitals in Cardiology/Heart Surgery, Gastroenterology/GI Surgery, Geriatrics, Nephrology, and Neurology/Neurosurgery, and in the top 50 in six other specialties in the 2018-2019 "Best Hospitals" issue. Mount Sinai's Kravis Children's Hospital also is ranked nationally in five out of ten pediatric specialties by U.S. News & World Report. The New York Eye and Ear Infirmary of Mount Sinai is ranked 11th nationally for Ophthalmology and 44th for Ear, Nose, and Throat. Mount Sinai Beth Israel, Mount Sinai St. Luke's, Mount Sinai West, and South Nassau Communities Hospital are ranked regionally.
