Longview Regional Medical Center Physician First in East Texas Region to Use Implantable Cardioverter Defibrillator (ICD)

LONGVIEW, TX (KLTV) - A Longview Regional Medical Center electrophysiologist, today announced the first in the Longview, as well as the East Texas Region to implant the Current® Plus implantable cardioverter defibrillator (ICD), featuring the SJ4 connector system. Dr. Massare is with The Longview Cardiology Clinic (in Longview). The St. Jude Medical SJ4 connector reduces the number of connections between the device and the wires (defibrillation leads) that send electrical impulses to the heart, which is intended to enable a streamlined implant procedure.

An ICD is a small device implanted in the chest to treat potentially lethal, abnormally fast heart rhythms (ventricular tachycardias or ventricular fibrillation), which often lead to sudden cardiac death (SCD). Nearly 1,000 people every day and more than 350,000 every year in the U.S. die from SCD. An ICD delivers potentially life-saving therapy from the device to the patient's heart through an insulated wire or lead.

Dr. Jorge Massare, MD. implanted the Current® Plus implantable cardioverter defibrillator (ICD), as part of Cardiac resynchronization therapy used to resynchronize the beating of the heart's lower chambers (ventricles), which often beat out of sync in heart failure patients. Studies have shown that CRT can improve the quality of life for many patients with heart failure, a progressive condition in which the heart weakens and loses its ability to pump an adequate supply of blood. About 5 million Americans suffer from heart failure, with 550,000 new cases diagnosed every year, according to the American Heart Association. 

A defibrillation lead is a long insulated wire that serves as a conduit between an implanted device and the heart. The lead sends electrical signals from the device to the heart to provide therapy needed to address abnormal heart rhythms. The lead also carries information from the

heart back to the implanted device, where the data can be used by the device to deliver therapy or make automatic adjustments, and used by physicians to determine optimal device settings and therapies for each patient.

The SJ4 connector system features a single connection between the device and the defibrillation lead, and a single set screw (used to tighten and secure the lead to the device). Previous defibrillator lead designs required three separate connections and four set screws. The reduced number of lead connections enables a streamlined implant procedure and also lessens the bulk of the lead at the implant site, which helps reduce the risk of lead-to-can abrasion, a known complication that can occur in patients who have an implantable device. 

The Durata® SJ4 defibrillation lead, developed by St. Jude Medical, is the thinnest lead available on the market today. It is designed for durability and reliability with a soft silicone tip and Optim® insulation, a hybrid insulation material that provides increased abrasion-resistance, along with the flexibility and handling characteristics that facilitate device implantation.  All patients implanted with an SJ4 connector system will initially be followed in a patient registry or on the Merlin.netTM Patient Care Network, via a Merlin@home® remote transmitter in their home, so physicians can be alerted to any important changes with the patient's device, leads or heart rhythm.
