Outline of Final Research Achievements

In this study, we sought to evaluate the effect of aortic valve stenosis on coronary circulation in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). Coronary flow velocity reserve (CFVR) of the left anterior descending artery was assessed by adenosine transthoracic echocardiography at baseline and immediately post-TAVI. Post-TAVI flow velocity at rest was lower than baseline flow velocity at rest (22.0±8.3 versus 28.3±8.4 cm/s, p<0.01). Post-TAVI CFVR was significantly higher than baseline CFVR (1.97±0.40 versus 1.70±0.33, p<0.01).

Academic Significance and Societal Importance of the Research Achievements

大動脈弁狭窄症は高齢化とともに罹患率が増加し、冠動脈疾患を高率に合併する。一方で大動脈弁狭窄症が冠循環に及ぼす影響は明らかではなく、大動脈弁狭窄症に合併した冠動脈狭窄の評価法は確立されていない。本研究により、冠血流速予備能は、大動脈弁狭窄症に対する経カテーテル的大動脈弁置換術後、すみやかに改善することが明らかとなった。本研究結果は、大動脈弁狭窄症の手術前後の冠循環動態の動的な変化により、大動脈弁狭窄症に合併する冠動脈疾患の機能的狭窄度が変化する可能性を示唆する。したがって、大動脈弁狭窄症に合併した冠動脈疾患に対しては、大動脈弁置換術と血行再建の時期を考慮した治療戦略を構築する必要がある。
