はじめに 大動脈弁狭窄症(AS)と冠状動脈疾患(CAD)を同時合併する症例に対しては,通常,外科的大動脈弁置換術(SAVR)と冠状動脈バイパス術(CABG)の同時手術が選択されてきた.しかし,開心術ハイリスク重症ASにCADを合併した場合,治療方針の決定に苦慮することも多い.われわれは,心筋梗塞発症後で虚血残枝を有する開心術ハイリスク重症ASに対して待機的に心尖部アプローチ(TA)での経カテーテル大動脈弁留置術(TAVI)とCABGを同時施行した1例を経験したので報告する.
Coronary artery disease (CAD) is often found concurrently in patients presenting with severe aortic stenosis (AS). Surgical aortic valve replacement (SAVR) and coronary artery bypass grafting (CABG) were usually selected with such patients. Recently, transcatheter aortic valve implantation (TAVI) is considered as a less invasive and more feasible treatment option in high-risk AS patients. A 74-year-old woman admitted due to acute myocardial infarction and treated with percutaneous coronary intervention revealed severe AS. Because of her comorbidities, concomitant transapical TAVI and CABG were performed with an excellent clinical course.
