Interventions

Cardiac sympathetic denervation.procedure

Patients underwent stellate ganglion block with 10 ml of levobupivacaine 0.25% and subsequently ultrasound-guided percutaneous bilateral cardiac sympathetic denervation , two neuroablative lesions were created using conventional radiofrequency treatment at 60°C, 20 V for 90 seconds.
