St. Jude Medical Gets European Approval for ICDs That Aid Patient Safety, Follow-up

AnalyST Accel ICD

Current Accel ICD

April 21, 2009 - St. Jude Medical Inc. yesterday announced CE mark approval of its AnalyST Accel and Current Accel implantable cardioverter defibrillators (ICDs), which automatically adjust therapy to changing patient needs for increased safety and accelerated follow-up.

The St. Jude Medical Accel family of ICD devices can be programmed to automatically monitor and adjust the level of electrical energy needed for stimulating the patient’s heart, which helps to ensure that adequate therapy is consistently administered while conserving battery life. The devices do this by measuring the heart’s reaction to electrical stimulation from the device and confirming that the heart is responding to the stimulation. This AutoCapture Pacing System feature provides the dual benefit of added safety for the patient and added efficiency for physicians, as vital threshold tests are performed automatically and results are available to the physician for review on demand during follow-up via a simple device interrogation. In the St. Jude Medical Accel family of ICDs, automatic threshold management is available on all leads for the first time.

The devices include a new AT/AF alert feature designed to notify physicians when a rapid atrial rate (atrial tachycardia/atrial fibrillation, or AT/AF) exceeds a programmed value or occurs over an extended time period. The devices can be programmed to notify the patient through a vibratory alert. Additionally, the devices have the ability to inform the patient’s clinic through the St. Jude Medical [email protected] transmitter and Merlin.net Patient Care Network (PCN). These features allow the physician to better manage patients’ atrial arrhythmias, such as AF, with appropriate medication or ablation.

“This family of devices enables me to streamline patient follow-up, allowing me to better manage therapy,” said Johannes Sperzel, M.D., of the Kerckhoff-Klinik in Bad Nauheim, Germany. “The fact that these tests are performed and thresholds are adjusted automatically means that I can quickly assess the results and then focus on other matters that concern the patient.”

In addition, the AnalyST Accel ICD includes the company’s proprietary ST monitoring diagnostic algorithm, which continuously monitors specific changes in the heart’s electrical system. These changes can indicate conditions such as ischemia. With the ST monitoring diagnostic algorithm, small changes in the ST segment are continuously recorded and plotted. The company said the information can then be retrieved by the physician via the Merlin Patient Care System during in-office follow-up. Alerts can also be configured so information about ST segment changes is sent directly to the physician through DirectAlerts notification, available with the Merlin.net PCN and the [email protected] patient transmitter. Because many cardiac episodes are transient in nature, the continuous ST monitoring capability available in the AnalyST Accel ICD gives physicians more comprehensive information over time compared to the standard electrocardiogram (ECG), St. Jude said.

Use of traditional Holter monitor leads can be an issue for patient compliance and comfort. The newer generation ambulatory cardiac monitors use an adhesive patch that sticks directly on the patient's chest and allows them to shower and go about daily activities without a belt mounted monitor or leads getting in the way. This is especially important for longer term monitoring of seven days or longer.
