Key result
Direct transseptal puncture using the steerable FlexCath sheath successfully achieved left atrial access in a female patient, avoiding the potential risks of sheath exchange.
Why the study?
The usual two-step transseptal puncture approach requires exchanging a fixed-curve sheath for a steerable sheath, carrying risks of air aspiration or losing left atrial access.

Direct transseptal puncture using a steerable sheath may be a feasible zero-exchange approach for left atrial access during cryoballoon ablation.
May support zero-exchange left atrial access in cryoballoon ablation; leaves open safety versus standard exchange in prospective studies.
Transseptal puncture during pulmonary vein isolation for atrial fibrillation is one of the crucial elements of the procedure. The usual two-step approach requires using a fixed-curve transseptal sheath for the puncture and then exchanging it for the steerable sheath, which can be associated with a potential risk of aspirating air into the system or losing left atrial access. We present a case study of a female patient in whom left atrial access was successfully achieved by direct transseptal puncture using the steerable FlexCath sheath, avoiding the potential risks of sheath exchange.
