FE FE Cardiomyopathies & Tumors 1

Question 1

Which cardiomyopathy pattern is most commonly associated with poorly controlled maternal diabetes?

Accepted Answer

Hypertrophic cardiomyopathy with septal hypertrophy

Answer

Diabetic fetopathy causes fetal hyperinsulinism, leading to hypertrophic cardiomyopathy with prominent interventricular septal hypertrophy.

Question 2

Fetal dilated cardiomyopathy is characterized by:

Accepted Answer

Ventricular dilation with reduced systolic function

Answer

Dilated cardiomyopathy features ventricular dilation, reduced fractional shortening, and impaired systolic function, often progressing to hydrops.

Question 3

Which infectious etiology is most commonly associated with fetal myocarditis leading to cardiomyopathy?

Accepted Answer

Coxsackievirus B

Answer

Coxsackievirus B is the most common viral cause of fetal myocarditis, which can lead to dilated cardiomyopathy and hydrops.

Question 4

Parvovirus B19 infection in the fetus primarily causes cardiac compromise through:

Accepted Answer

Severe fetal anemia causing high-output cardiac failure

Answer

Parvovirus B19 infects fetal erythroid progenitors, causing aplastic anemia and secondary high-output cardiac failure and hydrops.

Question 5

The most common primary cardiac tumor in the fetus is:

Accepted Answer

Rhabdomyoma

Answer

Rhabdomyomas are the most common primary fetal cardiac tumors, often multiple, and strongly associated with tuberous sclerosis complex.
