A surgical procedure known as left cardiac sympathetic denervation may be appropriate for patients who experience intolerable side effects from medication. This procedure is also recommended for patients who cannot control their symptoms through other methods. Sympathetic denervation involves removal of the nerves that supply adrenaline, a hormone that tells the heart to beat more quickly. This can reduce episodes of fainting and other symptoms caused by catecholaminergic polymorphic ventricular tachycardia. The procedure is performed under general anesthesia, and surgeons may use videoscopic equipment to assist them during the operation. The surgery usually lasts around forty minutes, and patients will be closely monitored with follow-up appointments. Before the procedure, patients will have a pre-op appointment, which may include a physical exam and tests such as an electrocardiogram.
