Use of a novel integrated dilator-needle system in cryoballoon procedures: a zero-exchange approach

Fig. 1. Overview of the transseptal procedural workflow with large bore sheaths. A Conventional transseptal workflow. B Transseptal workflow with the AcQCross system. The photos depict a AcQCross system in a AcQGuide Max 2.0 sheath. The intracardiac echocardiographic image shows tenting of the fossa ovalis during correct positioning of the dilator-sheath combination. LA, left atrium; LSPV, left superior pulmonary vein; SVC, superior vena cava
