Implantable cardiac defibrillator placement in a patient with persistent left superior vena cava and Brugada syndrome.
A 45-year-old man was diagnosed with new-onset atrial fibrillation. Control of ventricular rate led to spontaneous conversion to sinus rhythm. Subsequent electrocardiograms revealed ST segment changes characteristic of Brugada syndrome. Electrophysiology study demonstrated inducible ventricular fibrillation. During the placement of an implantable cardiac defibrillator the patient was found to have a persistent left superior vena cava. Persistent left superior vena cava is present in 0.3% of cases in autopsy series. To date, persistent left superior vena cava has not been reported in association with Brugada syndrome. We report such a case.
