Transaortic ablation of incessant ventricular tachycardia after aortic valve replacement by a mechanical prosthesis

We present the case of a young lady who underwent aortic valve replacement for serious regurgitation due to infectious endocarditis and in whom the postoperative course was complicated by incessant regular tachycardia with a narrow QRS complex. Because of a transient postoperative second-degree AV block, which precluded antiarrhythmic therapy commencement, she underwent an electrophysiological study demonstrating ventricular origin of the arrhythmia. The focal source in the left ventricular outflow tract was subsequently eliminated by radiofrequency ablation using the retrograde approach through the mechanical prosthesis.
