[Bezold-Jarisch reflex in a patient undergoing endoscopic sympathectomy for management of refractory angina pectoris: a case report].

BACKGROUND AND OBJECTIVES Ischemic cardiomyopathy is characterized by imbalance between supply and demand of myocardial oxygen. Endoscopic transthoracic sympathectomy is a therapeutic option indicated in refractory cases. However, the patient's position on the operating table may favor ischemic coronary events triggering the Bezold-Jarisch reflex. CASE REPORT A female patient, 47 years old, with refractory ischemic cardiomyopathy, admitted to the operating room for endoscopic transthoracic sympathectomy, developed the Bezold-Jarisch reflex with severe bradycardia and hypotension after placement in semi-sitting position to the procedure. CONCLUSION Bradyarrhythmia, hypotension, and asystole are complications potentially associated with patient placement in a semi-sitting position, particularly in cases with previous ischemic heart disease.
