超声心动图是一种存活程序,能够在心血管疾病的动物模型中评估结构和功能参数,并在临床前研究中用于评估潜在治疗方法的影响。超声心动图研究通常是在年轻的成年小鼠(即4-6周大)进行的。早期新生儿心血管功能的评估通常不会进行,因为小鼠的尺寸很小,而且相关的技术困难。最重要的挑战之一是,幼崽的四肢很短,无法到达超声心动图平台上的电极。体温是另一个挑战,因为幼崽非常容易受到温度变化的影响。因此,建立一个实用的小鼠超声心动图研究指南,以帮助研究人员发现早期的病理变化并研究心血管疾病随时间的进展是很重要的。目前的工作描述了一种在7日龄小鼠早期进行超声心动图检查的方案。还描述了新生小鼠心脏形态、功能和冠脉流量的超声心动图特征。
Echocardiography is a survival procedure that enables the evaluation of structural and functional parameters in animal models of cardiovascular disease and is used to assess the impact of potential treatments in preclinical studies. Echocardiographic studies are usually conducted with young adult mice (i.e., 4–6 weeks of age). The evaluation of early neonatal cardiovascular function is not usually performed because of the small size of the mouse pups and the associated technical difficulties. One of the most important challenges is that the short length of the pups’ limbs prevents them from reaching the electrodes in the echocardiography platform. Body temperature is the other challenge, as pups are very susceptible to changes in temperature. Therefore, it is important to establish a practical guide for performing echocardiographic studies in small mouse pups to help researchers detect early pathological changes and study the progression of cardiovascular disease over time. The current work describes a protocol for performing echocardiography in mouse pups at the early age of 7 days old. The echocardiographic characterization of cardiac morphology, function, and coronary flow in neonatal mice is also described.
