Tel: 149 221 478-97176, Fax: 149 221 478-32397, Email: firstname.lastname@example.org TM To the best of our knowledge, we report the first endocardial mapping within the left ventricle (LV) using the new 18-electrode Advisor HD Grid Mapping Catheter (St. Jude Medical, St. Paul, MN, USA) in a patient with a mitral valve clip (MVC). In this, 78-year-old patient with symptomatic premature beats a MVC was implanted 6 months prior to the ablation procedure. Additionally, a biventricular pacemaker was implanted 12 months ago consisting of a right ventricular (Biv-RV), a left ventricular (Biv-LV), and a right atrial lead (Biv-RA). Intracardial TM mapping of the LV was successfully performed using the Advisor HD Grid Mapping Catheter (St. Jude Medical, St. Paul, MN, USA) in con- TM junction with a 3D-mapping system (EnsiteVelocity , St. Jude Medical, Minneapolis, MN, USA). Panels A and B presented the created 3D TM maps in a left anterior and a left lateral superior view. Coronary vein sinus (CS) marks the decapolar diagnostic catheter (Inquiry ,St. Jude Medical, Minneapolis, MN, USA) placed in the coronary vein sinus. RV marks the quadripolar diagnostic catheter in the right ventricle. The transaortic passage of the mitral valve with the mapping catheter (white asterisk) was possible (Panel C, flouroscopic view right anterior oblique (RAO) 30 ). It was able to reach all areas of the LV. The catheter composed of a shaft containing two electrodes and four splines, each containing four electrodes (Panel D). Panel E shows a flouroscopic view (posterior–anterior) of the MVC (red arrow) after removal of TM all catheters. No interactions of the MVC and the mapping catheter were observed. Thus, mapping with the Advisor HD Grid Catheter appears to be feasible in patients with MVCs.
