Use of an angioplasty wire to perforate the interatrial septum for a difficult transseptal puncture.
With the expansion in catheter-based treatments for atrial fibrillation the number of transseptal punctures being performed by cardiac electrophysiologists has increased significantly. Although in general transseptal puncture is successful, in a small percentage of cases it cannot be achieved due to complex intraatrial anatomy. We report the case of a difficult transseptal puncture (TSP), performed where the conventional approach using a Brockenbrough needle sheath was unable to perforate the septum. TSP was only achieved using a novel technique assisted by an angioplasty wire.
