Abstract

Background Ventricular arrhythmias are a significant cause of morbidity and mortality in patients with ischaemic heart disease. When pharmacologic therapies, catheter ablation (CA), and implantable cardioverter defibrillator (ICD) are ineffective, stellate ganglion blockade (SGB), sympathectomy, and renal sympathetic denervation are considered. However, they are invasive for patients with high bleeding risk. We present a case of successfully recovering from haemodynamically unstable ventricular tachycardia (VT) storm with stellate ganglion phototherapy (SGP) in a non-invasive manner. Case summary A 73-year-old male presented to the emergency department with chief complaint of general malaise, resulting from VT storm associated with ischaemic cardiomyopathy. He had a history of CA and implantation of ICD. Despite multiple electrical cardioversions, pharmacologic therapies, and deep sedation with mechanical circulatory support (MCS), VT storm was not controlled. Thereafter, we irradiated the patient's neck with SGP to inhibit sympathetic neurological activity, which suppressed VT storm and dramatically improved his haemodynamic status. Discussion It has been reported that SGP is an alternative to SGB for refractory VT storm. Stellate ganglion phototherapy was easy and non-invasive to perform because we just irradiated the patient's neck with the near-infrared light for 5 min per day. If conventional therapies are ineffective in suppressing VT storm, SGP may be considered as a next step, especially for patients with high bleeding risk. However, since the effect of a single SGP lasts only 1–2 days, it should be performed as a bridge therapy to CA or sympathectomy. Stellate ganglion phototherapy may be effective in suppressing VT storm that requires MCS devices. [ABSTRACT FROM AUTHOR]
