Two-dimensional echocardiography has gained a role in the management of the acute complications of penetrating cardiac trauma and in precisely localizing retained bullet fragments within the heart. We report the case of an 8-year-old boy with chronic symptoms after a bullet wound. In this case, traumatic mitral regurgitation caused by mitral leaflet perforation and retention of the bullet in the tricuspid annulus occurred because of an unusual intracardiac course of the projectile. The diagnosis was made by transthoracic echocardiography. The ability of two-dimensional echocardiography to delineate the true location of the foreign body within the heart and Doppler ultrasound to identify mitral valve perforation helped guide a prompt, efficient, and successful surgical procedure.
二维超声心动图在穿透性心脏创伤急性并发症的处理以及精确确定心脏内残留子弹碎片的位置方面发挥了作用。我们报告一例8岁男孩在枪伤后出现慢性症状的病例。在该病例中，由于子弹在心脏内走行异常，导致二尖瓣叶穿孔引起创伤性二尖瓣反流，且子弹滞留于三尖瓣环。经胸超声心动图做出了诊断。二维超声心动图描绘心脏内异物真实位置的能力以及多普勒超声识别二尖瓣穿孔的能力有助于指导迅速、高效且成功的外科手术。
