Options For Treating Long QT Syndrome

Left Cardiac Sympathetic Denervation Surgery

Left cardiac sympathetic denervation surgery is a procedure in which certain sympathetic nerves in the chest are removed. The removal of these nerves allows the body to regulate the rhythm of the heart better. Left cardiac sympathetic denervation surgery helps with the management of long QT syndrome because the dangerous arrhythmias associated with the condition are caused by the sympathetic nerve stimulation of the heart. Left cardiac sympathetic denervation surgery is a treatment reserved for cases of long QT syndrome that cannot be successfully treated with the use of medications. Some patients may not respond appropriately to beta blockers or may have other medical issues that make taking beta blockers dangerous.

Left cardiac sympathetic denervation surgery is also not used in patients who can manage long QT syndrome successfully with an implantable cardioverter-defibrillator. However, in some patients, this condition may be severe enough to cause the device to deliver excessive appropriate shocks that can become uncomfortable. Many patients who undergo left cardiac sympathetic denervation surgery already have an ICD to treat their long QT syndrome. The changes made to the sympathetic nervous system after the procedure and the device will work in tandem to manage the condition. Left cardiac sympathetic denervation surgery will reduce the frequency of dangerous arrhythmias, and the ICD is active and will be ready when one does occur.
