Cardiac denervation procedure to treat refractory angina in a patient with Churg-Strauss syndrome and non-obstructive coronary lesions.

Cardiac involvement in Churg-Strauss syndrome is common and represents the main cause of mortality. We report the case of a patient with Churg-Strauss vasculitis, mitral regurgitation with left ventricular dysfunction, paroxysmal atrial fibrillation and refractory angina with non-significant coronary lesions. Cardiac denervation was proposed as an associated procedure to treat angina. The total removal of peri-adventitial and adventitial tissue around the superior vena cava, ascending aorta and main pulmonary trunk was performed. After 3 months of follow-up, the patient was angina-free and could resume his normal lifestyle.
