島村一男研究室は、心臓と大血管の疾患に対する外科治療および低侵襲治療の臨床成績向上を目指した研究を展開しています。弁膜症、心不全、先天性心疾患など様々な心疾患を対象としており、特に大動脈弁狭窄症や僧帽弁閉鎖不全症に対する外科的弁置換術と経皮的弁置換術の治療成績を比較検討しています。治療後の左心室の形態変化や心臓の逆リモデリング（心臓が正常な大きさに戻る過程）を評価し、患者予後を改善するための最適な治療戦略を探索しています。研究手法として、患者の術前・術後の画像検査データを詳細に分析する臨床研究が中心となっています。心臓CTや心エコーを用いて、大動脈根部の形態変化、心筋の厚さ変化、弁の機能評価などを定量的に測定し、長期予後との関連を統計学的に検証しています。また、右心不全の病態解明に向けて、動物実験でヒト由来の幹細胞から分化させた心筋細胞シートを移植し、治療効果を評価する研究も行っています。こうした取り組みを通じて、患者の基礎疾患や術後の解剖学的変化が長期成績に及ぼす影響を明らかにし、将来の再介入時のリスク評価や治療選択の指標となる知見を提供しています。
