The use of a steerable sheath reduced the time and amount of energy needed to achieve a bidirectional conduction block in the cavotricuspid isthmus (CTI). For patients in whom the establishment of a conduction block is difficult, a steerable sheath should be considered as a therapeutic option for typical atrial flutter (AFL) ablation.
Steerable versus non-steerable sheaths during pulmonary vein isolation: Impact of left atrial enlargement on the catheter-tissue contact force.
Masuda, M., Fujita, M., Iida, O., Okamoto, S., Ishihara, T., Nanto, K., . . . Uematsu, M. (2016). Journal of Interventional Cardiac Electrophysiology, 47(1), 99-107.
The beneficial effects of using steerable sheaths were more prominent in patients with severe left atrial (LA) enlargement.
Steerable versus non-steerable sheath technology in AF ablation: A prospective, randomized study.
Piorkowski, C., Eitel, C., Rolf, S., Bode, K., Sommer, P., Gaspar, T., … Hindricks, G.(2011). Circulation, 4(2), 157-65.
Atrial fibrillation (AF) catheter ablation using a manually controlled, steerable sheath for catheter navigation resulted in a significantly higher clinical success rate, with comparable complication rates and with a reduction in periprocedural fluoroscopy time.
Steerable sheath catheter navigation for ablation of atrial fibrillation: A case-control study.
Piorkowski, C., Kottkamp, H., Gerds-Li, J. H., Arya, A., Sommer, P., Dagres, N., Hindricks, G. (2008). Pacing and Clinical Electrophysiology, 31(7), 863-873.
An AF mapping and ablation approach solely using a manually controlled steerable sheath for catheter navigation improved the outcome of circumferential left atrial pulmonary vein (PV) ablation at similar intervention times and similar complication rates. The 6‐month success rate after a single LA intervention increased from 56% to 77%.
Operator-blinded contact force monitoring during pulmonary vein isolation using conventional and steerable sheaths.
Kimura, T., Takatsuki, S., Oishi, A., Negishi, M., Kashimura, S., Katsumata, Y., . . . Fukuda, K. (2014). International Journal of Cardiology, 177(3), 970-976.
Contact force (CF) or PV isolation was significantly different depending on the position of the catheter and the type of sheath.
