In order to determine whether echocardiography could be useful in predicting surgical mortality of aneurysmectomy, preoperative condensed M-mode echocardiographic scans were taken from both mid (standard position) and low (nearer apex) intercostal spaces and/or from the subxiphoid area in eighteen patients who were sent to surgery for aneurysmectomy. Eleven of the eighteen patients survived aneurysmectomy. All eleven had mid left ventricular dimensions less than 3.3 cm/m2 and low dimensions of 3.8 cm/m2 or less. Of the seven patients who died, the mid and low left ventricular dimensions exceeded 3.3 cm/m2 and 3.8 cm/m2, respectively, with one exception. The combination of abnormal mitral valve closure, a dilated mid dimension and lack of normal motion in opposing wall segments was only seen in six nonsurvivors. Echocardiography can provide information concerning the state of the left ventricle in patients with ventricular aneurysms and these findings may be helpful in predicting surgical mortality for aneurysmectomy.
为了确定超声心动图是否有助于预测动脉瘤切除术的手术死亡率，对18例因动脉瘤切除术而接受手术的患者，从肋间中部（标准位置）和下部（靠近心尖）间隙及/或剑突下区域进行了术前浓缩M型超声心动图扫描。18例患者中有11例动脉瘤切除术后存活。所有11例患者左心室中部尺寸均小于3.3cm/m²，下部尺寸为3.8cm/m²或更小。在7例死亡患者中，除1例外，左心室中部和下部尺寸分别超过3.3cm/m²和3.8cm/m²。二尖瓣关闭异常、中部扩张及相对壁段缺乏正常运动的组合仅在6例非存活者中出现。超声心动图可提供有关室壁瘤患者左心室状态的信息，这些发现可能有助于预测动脉瘤切除术的手术死亡率。
