This procedure, one of the first implants in the country and the first in the state of Mississippi, was performed on Friday, March 22 at Ocean Springs Hospital by Hugo Quintana, MD, of the Southern Mississippi Heart Center.
Implantable cardiac devices (ICDs) are sophisticated electronic devices that are implanted to help prevent sudden cardiac death in patients with ventricular tachycardia or fibrillation – a fast heart rhythm.
Known officially as BIOTRONIC Lumax 740 DX System, this newly available single-chamber ICD uses a single thin flexible wire, called a lead, to deliver an electrical pulse to the heart when the heart rate becomes dangerously fast and then returns the heart to its proper function. The innovative device can sense vital changes in heart rhythm in both the atrium and the ventricle of the heart through its single lead, offering an enhanced way of gaining important and useful atrial signal information without the risk of implanting multiple leads.
“Traditionally, we added an extra lead to enhance the discriminatory capabilities of the device and to avoid inappropriate shocks,” said Dr. Quintana. “Now, with this new device, that extra step is avoided and the procedure risk is then reduced.”
Traditional standard single-chamber ICDs come with limitations. The devices are designed only to sense changes in ventricular rhythm and are unable to sense atrial arrhythmias, such as atrial fibrillation (AF), correctly. This can result in an increased risk of an inappropriate shock or a stroke if AF is not detected.
The DX System expands the diagnostic capabilities of a standard single-chamber ICD with a single lead, in addition to featuring sophisticated sensors that allow for atrial monitoring and enhanced arrhythmia diagnosis.
The DX System also integrates with BIOTRONIK Home Monitoring ® allowing physicians to remotely follow their DX patient’s clinical and device statuses daily, at anytime, anywhere in the world. The cellular-based system has demonstrated the ability to detect clinically relevant events, including silent, asymptomatic arrhythmias, and device related issues, allowing for earlier medical intervention. The diagnostic capabilities of the DX System combined with Home Monitoring ® makes this a simple, yet sophisticated system for cardiac rhythm management.
