Percutaneous transapical approach and transcatheter closure for ventricular tachycardia ablation.

In patients with mechanical aortic and mitral valve prosthesis, left ventricular endocardial ablation via retrograde transaortic or antegrade transmitral approach carry high risk of catheter entrapment and death. In such cases, ablation can be performed via ventricular transseptal or transapical approach. Transapical approach, with the ease of catheter maneuverability and better endocardial contact, may be performed surgically or percutaneously. In this case report, we describe a patient with both aortic and mitral mechanical prosthesis who underwent ventricular tachycardia ablation via percutaneous transapical endocardial approach with the use of closure device.
