Cor triatriatum is a rare congenital cardiac anomaly, in which left ventricular filling is impeded by obstructive membrane in the left atrium. We administered spinal anesthesia for cesarean section in a patient with cor triatriatum (type III A1) with congestive heart failure. We optimized hemodynamics with the aid of pulmonary artery cathter. In general, cor triatriatum involves similar hemodynamic profiles to mitral stenosis and thus tachycardia should be avoided during anesthesia. However, in our patient, increasing the heart rate to 80-90 beats x min(-1) was beneficial in maintaining adequate systemic blood pressure and cardiac output. Spinal anesthesia could be a method of choice for cesarean section in a patient with cor triatriatum when adequate hemodynamic monitoring is available.
