Transesophageal Echocardiographic Monitoring of Critical Left Ventricular Outflow Tract Obstruction Following Mitral Xenograft Replacement -A Case Report

手術中使用經食道心臓超音波來監測在僧帽瓣置換手術後産生致命的左心室出口阻塞之病例報告

摘要


使用豬瓣膜置換僧瓣導致左心室出口阻塞是一個致命的併發症。手術中使用經食道心臓超音波來監測,可以幫助我們做早期的診斷,並使之後對病人的處理不至於拖延,本文報告一位接受僧帽瓣轉換手術造成左心室出口阻塞的病患,因爲手術中使用經食道心臓超音波來監測而做出正確的診斷,並討論之後的處理。

並列摘要


Left ventricular outflow tract obstruction (LVOTO) is a critical complication after mitral bioprosthesis. Intraoperative transesophageal echocardiographic (TEE) monitoring enables early diagnosis and guides prompt subsequent treatment. Here we report a case of mitral heart disease who developed critical LVOTO following mitral xenograft replacement. The values of intraoperative TEE in the disclosure of the LVOTO and its facilitation of successful management are discussed.
