The right ventricle (RV) is of lesser importance in acquired heart disease, but its role is of increasing importance in congenital heart disease. It may function as a subpulmonary ventricle or as a subaortic (systemic) ventricle in transposition complexes. The RV has a remarkable ability to adapt to pressure and volume load, but its size and function are often overlooked. Patients usually develop symptoms only after RV dysfunction has occurred, and in many diverse clinical scenarios, late referral is common. Advanced RV enlargement and dysfunction are responsible for not only impaired functional capacity but also lethal ventricular arrhythmias and sudden death. Appropriate imaging of the size and function of the RV are important because timely surgery on the pulmonary and tricuspid valves may preserve RV size and function. Adults with congenital heart disease should be followed at centers where there is an understanding of these problems so that valvular surgery can be considered when appropriate.
右心室（RV）在后天性心脏病中重要性较低，但在先天性心脏病中其作用的重要性日益增加。在转位综合征中，它可作为肺下心室或主动脉下（体循环）心室发挥功能。右心室具有显著的适应压力和容量负荷的能力，但其大小和功能常常被忽视。患者通常仅在右心室功能障碍发生后才出现症状，并且在许多不同的临床情况下，延迟转诊很常见。严重的右心室扩大和功能障碍不仅会导致功能能力受损，还会引发致命的室性心律失常和猝死。对右心室大小和功能进行适当的成像很重要，因为及时对肺动脉瓣和三尖瓣进行手术可能会保留右心室的大小和功能。患有先天性心脏病的成年人应在了解这些问题的中心接受随访，以便在适当的时候考虑进行瓣膜手术。
