Type A univentricular heart is a severe congenital cardiac defect; 50% of patients are dead 14 years after diagnosis, a death rate of 4.8% per year. Type C univentricular heart is even more lethal; 50% of patients are dead 4 years after diagnosis. Pulmonary stenosis did not protect either group of patients in terms of overall survival. Of the patients in class I or II at initial diagnosis, 34% of patients with type A and 12% of those with type C were in class III or IV or had died at follow-up. The most common causes of death were dysrhythmia, congestive heart failure and sudden and unexplained death.
A型单心室心脏是一种严重的先天性心脏缺陷；50%的患者在确诊后14年死亡，年死亡率为4.8%。C型单心室心脏的致死性更强；50%的患者在确诊后4年死亡。就总体生存率而言，肺动脉狭窄并未对这两组患者起到保护作用。在初诊时为I级或II级的患者中，随访时，A型患者中有34%、C型患者中有12%变为III级或IV级或已死亡。最常见的死亡原因是心律失常、充血性心力衰竭以及突然不明原因死亡。
