Can an atrial transseptally inserted multielectrode basket catheter guide intraoperative mapping and ablation of sustained ventricular tachycardia in a patient with mitral valve prolapse?
A multielectrode basket catheter can be successfully used transseptally to guide intraoperative mapping and ablation of ventricular tachycardia in patients with mitral valve prolapse.
Ventricular tachycardia occurs frequently in patients with mitral valve prolapse. If antiarrhythmic drug therapy fails or mitral valve surgery is indicated, concomitant arrhythmia surgery may be considered. This report describes the first clinical use of an atrial transseptally inserted multielectrode basket catheter, placed across the mitral valve, to guide intraoperative mapping and ablation of monomorphic sustained ventricular tachycardia in association with mitral valve prolapse. Endocardial covering and signal quality of this percutaneous mapping catheter were of good quality, allowing an accurate localization of the site of origin of the tachycardia.
Dessel et al. (Fri,) studied this question.
