Outline of Final Research Achievements

Using the simultaneous electrode / optical mapping system, we confirmed the high correlation between the electrode measurement by ExTRa Mapping system developed by Ashihara et al. This revealed the usefulness of the ExTRa Mapping in phase variance analysis. Numerical analysis and experiments using rabbit heart preparations showed the possibility of guiding the Spiral Wave (SW) center to the interventricular groove of the heart by cooling the linear region between the SW center and the boundary of the heart. Numerical analysis showed that there is a phase discontinuity that produces phase variance at the center of a meandering SW. This provided theoretical basis showing importance of phase variance analysis in controlling arrhythmia. Furthermore, both initiation and propagation of excitation from the sinus node were reproduced by numerical analysis using a three-dimensional atrial model. Features similar to those of early paroxysmal atrial fibrillation was reproduced.

Academic Significance and Societal Importance of the Research Achievements

我が国では心房細動に対する有効な治療法の開発が医療経済の観点からも求められる。発作性心房細動については肺静脈隔離術の普及によって治療成績が向上したが,心筋の特性変化を認める非発作性(持続性・長期持続性)心房細動患者に対する治療は未だ有効な手法がない。本研究では,位相分散解析という手法を用いた効果的除細動治療の実現に向けて,心筋冷却の効果解析によりその基本概念を確認した。また基礎研究での知見を臨床につなげるために,光学マッピングと電極マッピングとの関連性を明らかにした。研究成果は心臓細動中に発生する渦巻き型旋回興奮波(Spiral Wave)の停止戦略を考えるための重要な知見を与えている。
