The sizing of aortic valve (AV) homografts for optimum function requires an accurate measurement of the aortic annulus. Typically, this measurement is obtained directly with sizers in the open aorta. We describe the use of intraoperative transesophageal echocardiography (IOTEE) to measure the aortic annulus and select the appropriate AV homograft before cardiopulmonary bypass and aortic cross-clamping. Thirty-two patients underwent AV homograft insertion between March 1993 and March 1996 and had IOTEE. There were 13 women and 19 men. Mean age was 58 +/- 14 years. IOTEE measurements were satisfactory in sizing in all patients, and no extraordinary surgical measures were necessary to insert the AV homografts. Early postoperative follow-up showed trivial or mild regurgitation of all homografts. Prebypass IOTEE is reliable in guiding the selection of optimal AV homografts.
为实现最佳功能而对主动脉瓣（AV）同种异体移植物进行尺寸确定需要准确测量主动脉瓣环。通常，这种测量是在开放的主动脉中直接使用尺寸测量器获得的。我们描述了在体外循环和主动脉交叉钳夹之前，使用术中经食管超声心动图（IOTEE）测量主动脉瓣环并选择合适的AV同种异体移植物的方法。1993年3月至1996年3月期间，32例患者接受了AV同种异体移植物植入并进行了IOTEE检查。其中女性13例，男性19例。平均年龄为58±14岁。IOTEE测量在所有患者的尺寸确定中均令人满意，并且在植入AV同种异体移植物时无需采取特殊的手术措施。术后早期随访显示所有同种异体移植物均有轻微或轻度反流。体外循环前的IOTEE在指导选择最佳AV同种异体移植物方面是可靠的。
