Cardiac function is about creating and sustaining blood in motion. This is achieved through a proper sequence of myocardial deformation whose final goal is that of creating flow. Deformation imaging provided valuable contributions to understanding cardiac mechanics; more recently, several studies evidenced the existence of an intimate relationship between cardiac function and intra-ventricular fluid dynamics. This paper summarizes the recent advances in cardiac flow evaluations, highlighting its relationship with heart wall mechanics assessed through the newest techniques of deformation imaging and finally providing an opinion of the most promising clinical perspectives of this emerging field. It will be shown how fluid dynamics can integrate volumetric and deformation assessments to provide a further level of knowledge of cardiac mechanics.
心脏功能在于使血液流动并维持其流动状态。这是通过心肌变形的适当顺序来实现的，其最终目标是产生血流。变形成像为理解心脏力学做出了重要贡献；最近，多项研究证实了心脏功能与心室内流体动力学之间存在密切关系。本文总结了心脏血流评估的最新进展，强调了其与通过最新变形成像技术评估的心脏壁力学之间的关系，并最终对这一新兴领域最具前景的临床前景发表了看法。将展示流体动力学如何整合容积和变形评估，以提供对心脏力学更深层次的认识。
