Right ventricular (RV) function is a strong independent predictor of outcome in a number of distinct cardiopulmonary diseases. The RV has a remarkable ability to sustain damage and recover function which may be related to unique anatomic, physiologic, and genetic factors that differentiate it from the left ventricle. This capacity has been described in patients with RV myocardial infarction, pulmonary arterial hypertension, and chronic thromboembolic disease as well as post-lung transplant and post-left ventricular assist device implantation. Various echocardiographic and magnetic resonance imaging parameters of RV function contribute to the clinical assessment and predict outcomes in these patients; however, limitations remain with these techniques. Early diagnosis of RV function and better insight into the mechanisms of RV recovery could improve patient outcomes. Further refinement of established and emerging imaging techniques is necessary to aid subclinical diagnosis and inform treatment decisions.
右心室（RV）功能是许多不同心肺疾病预后的强有力的独立预测因子。RV 具有显著的承受损伤和恢复功能的能力，这可能与将其与左心室区分开来的独特解剖、生理和遗传因素有关。这种能力在 RV 心肌梗死、肺动脉高压和慢性血栓栓塞性疾病以及肺移植后和左心室辅助装置植入后患者中得到了描述。RV 功能的各种超声心动图和磁共振成像参数有助于这些患者的临床评估和预测结局；然而，这些技术仍然存在局限性。RV 功能的早期诊断和更好地了解 RV 恢复的机制可以改善患者的结局。进一步完善现有的和新兴的成像技术对于辅助亚临床诊断和为治疗决策提供信息是必要的。
