HU ET AL.: Left Cardiac Sympathetic Denervation via Thoracoscope to Treat
Long QT Syndrome. Purpose: Long QT syndrome (LQTS) is a cardiovascular disorder
characterized by prolongation of the QT interval on ECG and presence of syncope,
seizures, and sudden cardiac death. The therapy for LQTS is mainly dependent
on medicines. The aim of the present study was to investigate the feasibility
and efficacy of a new surgical method of cardiac sympathectomy for LQTS patients.
Methods: Left cardiac sympathetic denervation (LCSD) were conducted on
4 LQTS patients who were resistant to b-blockers.
Patients' ECG and clinical symptoms were assessed before and after the surgery.
Results: LCSD was successful in all patients. QTc decreased from 0.54
Key words : Corrected QT interval, Holter monitoring ECG, horizontal bike exercise test, left cardiac sympathetic denervation, long QT syndrome(LQTS)
