triangular, echogenic mass within the chest
The embryonic heart begins as:
two tubes
Tetralogy of fallot consists of all of the following except: A. Overriding Aortic Root B. Ventricular Septal Defect C. Pulmonary Stenosis D. Left ventricular hypertrophy
left ventricular hypertrophy
Eventration of the diaphragm is best described as:

Fetal lung maturity can be assessed using the:
lecithin to sphingomyelin ratio
Fetal rhabdomyomas are associated with which of the following:
tuberous sclerosis
Which of the following is considered to be the most common cardiac defect: A) hypoplastic right heart syndrome B) transposition of the great vessels C) hypoplastic left heart syndrome C) ventricular septal defect D) ventricular septal defect
