The significant advances made in ultrasound microbubble technology now permits reliable, reproducible left ventricular opacification, and this review reiterates the evidence that has shown contrast echocardiography to be clinically effective, to reduce downstream costs and to spare patients further, potentially hazardous investigations. Despite the evidence and the advances, there remains ambivalence towards the administration of contrast agents in echocardiography laboratories throughout the world, particularly in the performance of rest studies. Therefore, this review also addresses some of the reasons for the suboptimal uptake of contrast agents and encourages physicians, sonographers, and accreditatory bodies to adopt a different approach towards the difficult-to-image patient.
超声微泡技术的重大进展现在使得可靠、可重复的左心室显影成为可能，本综述重申了对比超声心动图具有临床有效性的证据，可降低下游成本，并使患者免于进一步进行潜在危险的检查。尽管有证据和进展，但在全世界的超声心动图实验室中，对对比剂的应用仍存在矛盾，特别是在进行静息研究时。因此，本综述还探讨了对比剂应用不理想的部分原因，并鼓励医生、超声技师和认证机构对难以成像的患者采取不同的方法。
