We studied the feasibility of transesophageal echocardiography to guide endomyocardial biopsies in five heart transplant patients and two baboons with heart transplantations. The patients were 1 month to 1.5 years old with weight range of 2.9 to 9.5 kg. The two juvenile baboons weighed 6.6 and 7 kg. Transesophageal echocardiography was performed uneventfully in all cases with the use of sedation and anesthesia, which were necessary for catheterization. The combination of four-chamber and short-axis views easily identified the exact location of the bioptome within the heart, views that fluoroscopic imaging could not provide. Transesophageal echocardiography proved to be a safe and useful tool for guiding the endomyocardial biopsy procedure. With further refinement endomyocardial biopsy with only transesophageal echocardiography guidance could become the routine method for endomyocardial biopsies in infants, particularly when there are abnormalities of heart situs or position.
我们研究了经食管超声心动图引导5例心脏移植患者及2只接受心脏移植的狒狒进行心内膜心肌活检的可行性。患者年龄为1个月至1.5岁，体重范围为2.9至9.5千克。两只幼年狒狒体重分别为6.6千克和7千克。在所有病例中，经食管超声心动图检查均在镇静和麻醉下顺利进行，而镇静和麻醉是导管插入术所必需的。四腔心和短轴视图相结合能够轻松确定活检钳在心脏内的确切位置，这是荧光透视成像无法提供的视图。经食管超声心动图被证明是指导心内膜心肌活检程序的一种安全且有用的工具。随着进一步完善，仅在经食管超声心动图引导下进行心内膜心肌活检可能会成为婴儿心内膜心肌活检的常规方法，尤其是在存在心脏位置异常的情况下。
