Facilitation of rotablator-stenting by measuring angiographic lesion length with the navicath (type-MUTO), a new measuring microcatheter.
In the present study, the usefulness and feasibility of a new measuring microcatheter, the Navicath (Type-MUTO) microcatheter, for facilitating the stenting procedure subsequent to ablation using a rotablator (rota-stenting) is described. A method for measuring the length of the targeted lesion (lesion length) angiographically with the Navicath when exchanging the guide wires is presented using 2 representative cases of rota-stenting. In addition, the validity of the selected stent according to the measurement of lesion length with the Navicath was evaluated by comparing the length of the selected stent with lesion length before PCI measured by quantitative coronary angiography. Based on the results obtained, we believe the Navicath is useful for facilitating rota-stenting, and may even be applicable to PCI in general.
