Abstract:
We report a case of recurrent ventricular tachycardia from severe aortic stenosis that improved after percutaneous aortic balloon valvuloplasty and transcatheter aortic valve replacement. The electrocardiographic features of the arrhythmia were compatible with ventricular tachycardia originating from the left ventricle. Myocardial ischemia and electrolyte abnormalities were ruled out. Clinicians should be aware that recurrent left ventricular tachycardia associated with severe aortic stenosis is a potentially reversible condition by transcatheter intervention. <Learning objective: Calcific aortic stenosis is a common problem in the elderly. There is a high prevalence of ventricular arrhythmias in these patients. Transcatheter aortic valve replacement is a relatively new procedure for high-risk patients with severe aortic stenosis. We report a case that illustrates for the first time resolution of recurrent ventricular tachycardia after percutaneous aortic balloon valvuloplasty and transcatheter aortic valve replacement in an elderly patient with severe aortic stenosis.>.

The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
