The importance of the once-obscure right ventricle is becoming evident. Even in disorders that primarily affect the left ventricle, the once-considered-passive conduit has proved essential for maintenance of normal cardiac output. In coronary artery disease, the function of the right ventricle is affected by both its circulation and the after-load placed on it by dysfunction of the left ventricle. In congestive heart failure, right ventricular function relates to functional capacity, whereas left ventricular function does not, and right ventricular ejection fraction is a useful prognostic guide in these patients. In mitral and aortic valvular disease, the role of the right ventricle is only now becoming evident, and the precise interplay of all factors has yet to be explained. In systemic hypertension, it is likely that the pulmonary circulation is affected by the same humoral factors that elevate systemic pressures.
曾经被忽视的右心室的重要性正日益显现。即使在主要影响左心室的疾病中，这个曾经被认为是被动管道的结构已被证明对维持正常心输出量至关重要。在冠状动脉疾病中，右心室的功能受到其自身循环以及左心室功能障碍所施加的后负荷的影响。在充血性心力衰竭中，右心室功能与功能能力相关，而左心室功能则不然，右心室射血分数是这些患者有用的预后指标。在二尖瓣和主动脉瓣疾病中，右心室的作用直到现在才变得明显，所有因素之间的确切相互作用尚待解释。在系统性高血压中，肺循环很可能受到升高体循环压力的相同体液因素的影响。
