- Fainting reoccurred in 185 of the 511 study patients (36 percent).
- Fainting was documented by the ICM in 141 (76 percent) of these patients.
- The Reveal ICM diagnosed about half (51 percent) of patients with reoccurring fainting as an asystolic event, indicating them for a pacemaker and making them eligible for the treatment phase of the study. These patients received a dual-chamber Medtronic pacemaker and were randomized 1:1 (pacemaker on and pacemaker off).
“This study shows that a difficult-to-diagnose patient population can be identified early in the patient care pathway through the use of insertable cardiac monitors, and that treatment is available and effective for patients with asystolic syncope,” said Elizabeth Hoff, vice president and general manager of Cardiac Connected Care at Medtronic.Medtronic pacemakers are currently indicated for use in patients who have experienced one or more of the following conditions: symptomatic paroxysmal or permanent second- or third-degree AV block, symptomatic bilateral bundle branch block, symptomatic paroxysmal or transient sinus node dysfunctions with or without associated AV conduction disorders and bradycardia-tachycardia syndrome. About Syncope Syncope, also known as fainting, is a sudden loss of consciousness that usually occurs when the blood pressure drops and not enough oxygen reaches the brain. Syncope is difficult to diagnose as syncopal episodes are often too infrequent and unpredictable for detection with conventional monitoring techniques. As a result, approximately 1.5 million people worldwide suffer from unexplained syncope. Syncope accounts for one to six percent of hospital admissions 1 and one percent of total ER visits 2 per year. In almost 10 percent of patients, syncope has a cardiac cause; in 50 percent, a non-cardiac cause; and in 40 percent of patients the cause of syncope is unknown. 3 Reveal In-Office Study Results In addition to the late breaker, there will be an ACC poster presented on the safety and feasibility of implanting ICMs in the clinic in-office setting. Sixty-five patients at 9 centers were implanted with a Reveal ® ICM and followed for an average 87 days. The study met the primary endpoint of a 3.4% 90-day event rate of patients with procedure-related complications requiring resolution by surgical intervention. It found that in-office ICM insertion can be accomplished in a more convenient setting, and with a high level of physician satisfaction, while expediting patient diagnoses. In collaboration with leading clinicians, researchers and scientists, Medtronic offers the broadest range of innovative medical technology for the interventional and surgical treatment of cardiovascular disease and cardiac arrhythmias. The company strives to offer products and services that deliver clinical and economic value to healthcare consumers and providers worldwide.
