title: [General anesthesia for a patient with primary aldosteronism complicated with hypertrophic nonobstructive cardiomyopathy].
abstract: We report a patient with primary aldosteronism (PA) complicated with hypertrophic nonobstructive cardiomyopathy (HNCM) who underwent resection of a left adrenal tumor. Amrinone was administered to improve the features of congestive heart failure induced by retention of body fluid. Maintaining adequate preload and afterload and preventing excessive increases in contractility are important in the anesthetic management of patients with hypertrophic obstructive cardiomyopathy (HOCM). Although the preoperative diagnosis may be HNCM, stenosis of the left ventricular outflow tract may occur due to hemodynamic changes during surgery. Therefore amrinone is not often used for patients with HNCM. We inserted a pulmonary arterial catheter (Swan-Ganz CCO Thermodilution Catheter) and measured the cardiac output continuously to monitor hemodynamic changes. The symptoms of pulmonary edema were diminished one month after the surgery. These findings suggest that the increased blood volume induced by PA is a main factor aggravating preoperative congestive heart failure with HNCM.
