Abstract:
In two patients with severe aortic stenosis successful resuscitation from ventricular fibrillation was documented by Holter recording/ECG monitoring. After aortic valve replacement programmed ventricular stimulation was performed in both patients, but ventricular tachycardia/ventricular fibrillation was not inducible. The patients were left without antiarrhythmic therapy and have been free from cardiac events for 18 and 20 months, respectively. The prognostic value of postoperative electrophysiologic testing after aortic valve replacement in patients with severe aortic stenosis and preoperative resuscitation is discussed.
