Important recent developments have occurred in echocardiography that are already being used clinically. Portable ultrasound devices that weigh less than five pounds are capable of performing a complete bedside echo exam. An intracardiac echocardiographic catheter has recently been introduced that can be placed intracardiac via a vein and navigated within right heart chambers to obtain detailed anatomical landmarks that guide catheter based interventional procedures such as intracardiac ablation and closure of atrial septal defects and patent foramen ovale. Tissue Doppler imaging is finding its role in detecting mechanical asynchrony in patients with congestive heart failure who might benefit from biventricular pacing. The availability of real-time 3D echocardiography has for the first time made assessment of complex cardiac anatomy possible. This review discusses each of these new developments and their potential impact on the practice of echocardiography and cardiology in general.
超声心动图领域最近出现了一些重要进展,这些进展已在临床中得到应用。重量不足五磅的便携式超声设备能够进行完整的床边超声心动图检查。最近引入了一种心内超声心动图导管,它可以通过静脉放置在心腔内,并在右心腔内导航,以获取详细的解剖标志,从而指导基于导管的介入手术,如心内消融以及房间隔缺损和卵圆孔未闭的封堵。组织多普勒成像在检测充血性心力衰竭患者的机械不同步方面发挥着作用,这些患者可能从双心室起搏中获益。实时三维超声心动图的出现首次使评估复杂心脏解剖结构成为可能。本综述讨论了这些新进展中的每一项及其对超声心动图和心脏病学实践的潜在影响。
