We present a case of an antenatally diagnosed congenital aneurysm of the left ventricle in which fetal cardiac contractility was evaluated by measuring the fetal isovolumetric contraction time (ICT). The workup of the fetus at 26 weeks' gestation led to the identification of a left ventricle aneurysm. Initially, the value of ICT of the left ventricle indicated adequate cardiac function. However, the fetal ICT was gradually prolonged, suspecting deteriorated cardiac contractility. Following an uncomplicated term delivery, a postnatal echocardiogram showed normal cardiac function. It is considered that because of the hypokinesis of the wall of the left ventricular aneurysm, the ICT did not fully predict cardiac function in this setting.
