St. Anthony Hospital offers newly approved S-ICD system for patients at risk of sudden cardiac arrest

Image removed.The S-ICD System, developed by Boston Scientific, is designed to provide the same protection from SCA as transvenous implantable cardioverter defibrillators (ICDs). However, this entire device sits just below the skin and eliminates the need for thin, insulated wires known as electrodes or leads" to be placed into the heart itself. This leaves the heart and blood vessels untouched (see graphic attached).

The biggest benefit of S-ICD is that it eliminates problems associated with the intravenous leads," said cardiologist Thomas Svinarich, MD, FACC, with St. Anthony Hospital. Leads implanted in the heart and blood vessels are constantly moving. Electrode wires wear out and have to be replaced. Here, we have a subcutaneous lead under the skin, on the chest that isnt subject to those stresses. So we expect patient complications, in the long run, to be much reduced."

Svinarich said, Candidates for this system include younger patients, active patients, patients prone to infection and patients likely to have a long life span following implantation."

Were very excited to be one of the first hospitals in the region to offer the S-ICD. Its a very important breakthrough," said Svinarich.

Sudden cardiac arrest is an abrupt loss of heart function. Most episodes are caused by the rapid and/or chaotic activity of the heart known as ventricular tachycardia or ventricular fibrillation. Its estimated that approximately 850,000 people in the United States are at risk for SCA and could benefit from an ICD device.

The S-ICD System has two main components. The pulse generator powers the system, monitors heart activity and delivers an electric pulse, if needed, to stop an abnormal heart rhythm. The electrode enables the device to sense the problematic cardiac rhythm and deliver the corrective shock. Both components are implanted just under the skin the generator at the side of the chest, just under the armpit, and the electrode beside the breastbone.
