Prenatal Ultrasound Diagnosis of Fetal Unicuspid Aortic Valve With Cardiac Rhabdomyoma: A Case Report
Abstract
Prenatal diagnosis of unicuspid aortic valve (UAV) is exceptionally rare. UAV diagnosis can be achieved prenatally via ultrasound; however, it becomes challenging when UAV coexists with a large cardiac rhabdomyoma (CR) occupying significant left ventricular cavity space. The diagnosis of UAV deformity proves particularly challenging due to two compounding pathophysiological factors: altered hemodynamics prevent detection of characteristic high-velocity antegrade flow across the stenotic valve and mechanical compression exerted by a sizable rhabdomyoma further obscures typical diagnostic features. We report a case of fetal UAV associated with CR.
