Sustained monomorphic left ventricular outflow tract tachycardia early after aortic valve replacement.
Sustained monomorphic ventricular tachycardia (VT) after valve surgery is uncommon. Cases  of focal VT or bundle-branch re-entry after aortic valve surgery have been reported. We present  the case of a 60 year-old patient with an incessant outflow tract VT early after aortic valve  replacement. We suggest the disease process affecting the valve and adjacent area, and/or the  surgical procedure, might somehow relate to VT substrate adjacent to the aortic annulus.
