TCT-824 Reduction in Ventricular Arrhythmias with Ixmyelocel-T: Results from the IxCell-DCM Trial

Left ventricular perforation in a patient with a left ventricular aneurysm during NOGA® catheter mapping

Endocardial mapping of the left ventricle (LV) using the NOGA® XP Cardiac Navigation System can identify chronically ischemic and viable myocardium in patients with coronary artery disease by generating electromechanical maps. These maps are very useful when targeting myocardial tissue for injection of stem cells. We present the case of a woman who developed a perforation at the site of an LV aneurysm during NOGA mapping prior to the transendocardial injection of stem cells, as part of a multicenter clinical trial. The presence of an LV aneurysm is currently not a contraindication (or caution) to the use the NOGA mapping catheter. As the field of stem cell therapy evolves and the use of this technique increases, operators must be aware that the presence of an LV aneurysm may increase the risk of perforation during a NOGA mapping procedure.
