  • Title: Postaortic valve replacement bradycardia induced torsades de pointes.
    Author: Amchentsev A, Haq SA, Holt JJ, Khan A, Gelles J, Kassotis J.
    Journal: Angiology; 2008; 59(1):111-3. PubMed ID: 18319232.
    Abstract:
    The authors present an unusual case of torsades de pointes (Tdp) in an elderly woman with a history of aortic stenosis, status post aortic valve replacement. She was admitted for atrial fibrillation with a slow ventricular response. At the time of admission, the patient was asymptomatic and not taking any medications known to be associated with QT prolongation. During hospitalization, she developed episodes of Tdp without any provocable cause. This case highlights the occurrence of Tdp secondary to conduction disturbance caused by aortic valve surgery.
