  • Coconut Atrium Causing Restrictive Physiology in the Right Ventricle

    Tomitaka Wakaki, Wakana Sato, Mayu Suzuki, Hiroyuki Watanabe

    Internal Medicine ( Internal Medicine )  63 ( 16 ) 2289 - 2292   2024  [Refereed]

    Research paper (journal)  

    <p>We herein report a 61-year-old woman with a history of mitral valve replacement for rheumatic fever who presented with crural edema and ascites. Computed tomography showed massive left atrial (LA) calcification involving the interatrial septum, termed "coconut atrium." Catheterization revealed not only pulmonary artery hypertension but also a large V-wave in the pulmonary artery wedge pressure waveform and a dip-and-plateau pattern of right ventricular pressure. Three-dimensional transthoracic echocardiography confirmed the early attainment of peak LA volume and a decreased LA expansion index. Stiff LA syndrome due to coconut LA results in the development of restrictive right ventricular physiology. </p>

    <jats:title>要旨</jats:title><jats:p><jats:bold>【目的】</jats:bold>2019年3月に日本循環器学会から発行された急性冠症候群診療ガイドラインの中で，当地のような緊急PCI非実施地域においては再灌流治療までの時間の遅れを最小限にするため，病院到着から転院搬送開始までの時間（door–in door–out time: DIDO）を30分以内にするようにと推奨されているが，本邦におけるDIDO時間に関する報告はこれまでほとんどない。当地における現状を明らかにするため，後ろ向きコホート研究を行った。<jats:bold>【対象】</jats:bold>2016年4月～2020年3月に当院でSTEMIと診断され緊急転院搬送となった39症例（平均年齢70歳，男性34例）のDIDO時間を算出し検証した。<jats:bold>【結果】</jats:bold>DIDO時間の中央値は95分（45～193分）であった。DIDO≤30分は0例，DIDO≥91分が20例であった。患者背景別や状況別についてDIDO時間を比較したが，有意差は認めなかった。<jats:bold>【結語】</jats:bold>当地域ではSTEMIで転院搬送を要した患者に対して，新ガイドラインで推奨されている30分以内のDIDO時間が全く守られていないことが明らかとなった。今後のDIDO短縮には，院内における迅速な診断と医師応召だけでなく，病院前12誘導心電図システムの導入など，近隣医療機関や消防機関との相互協力が必要と考えられる。</jats:p>
