- Surface defects, blood flow shear rates and mechanical stresses are contributing factors in the calcification process of polymeric devices exposed to the blood flow. A number of experiments were performed to evaluate the effect of surface defects such as roughness and cracks and flow shear rate on t

- AIMS: In patients with a suspicion of prosthetic valve endocarditis (PVE), detection of perivalvular infection can be difficult based only on echocardiography. The aim of this retrospective study was to test the interest of radiolabelled leucocyte scintigraphy (LS) for the detection of perivalvular

- Prosthetic valve endocarditis (PVE) due to fast-growing nontuberculous mycobacteria (NTM) has been reported anecdotally. Reports of PVE with slowly growing NTM, however, are lacking. We present here one case of PVE and one case of bloodstream infection caused by Mycobacterium chimaera. Randomly ampl

機械弁と生体弁の比較
| 機械弁 | 生体弁 | |
| 種類 | 二様弁 | 1. 異種生体弁(ブタ大動脈弁、牛心膜弁) 2. 同種生体弁(大動脈弁置換術のみ) →ヒト大動脈弁、自己肺動脈弁 |
| 利点 | 耐久性(10年以上) | ・抗血栓療法が不要 ・自然な弁機能 |
| 欠点 | 血栓予防のために 生涯ワーファリンの服用が必要 |
10年以下(再手術を要する) |
| 適応 | 普通は機械弁を使用 | 1. 出産希望 2. 出血性疾患がある症例 3. 小児(自己肺動脈弁) |
人工弁と生体弁まとめ
- 人工弁(機械弁)は10年以上もつ耐久性があるというメリットがあるが、一方で弁に血栓が形成されないよう生涯にわたって抗血栓薬を服用する必要がある。生体弁は異種生体弁(ブタ大動脈弁、ウシ心膜弁)と同種生体弁(ヒト大動脈弁、自己肺動脈弁)があるが、いずれも抗血栓薬の服用が不要であるというメリットがあり、これは出産を希望している女性、小児、出血性疾患がある症例においては良い適応となる。一方で、耐久性に問題があり、10年を超えると弁機能不全となり交換を要するというデメリットがある。
