Churg-Strauss syndrome is an allergic granulomatous angitis and the organ most commonly involved in this condition is the lung. However, this syndrome also affects the skin, cardiovascular system, kidney, peripheral nervous system and gastrointestinal system. Cardiac involvement is a rare complication but can lead to rapid-onset heart failure as the result of specific cardiomyopathy. Pericardial effusion may also occur. Acalculous cholecystitis is also a rare complication of Churg-Strauss syndrome. Here, we present a case of a patient with Churg-Strauss syndrome and severe heart failure scheduled for cholecystectomy due to acalculous cholecystitis. The patient had mild asthma symptoms, peripheral neuritis in both legs, and severe heart failure. During the preoperative period, steroids, β₂ agonists, diuretics, and antihypertensive drugs were administered. During anesthesia we attempted to prevent compromising the patient's cardiac and pulmonary functions. The surgery was completed successfully, and the patient was discharged without any complications.
