A.	Primary Pulmonary Hypertension
B.	Eisenmenger’s syndrome
C.	Marfan’s with aortic root dilation
D.	WPW syndrome

Show Answer

Correct Answer » D Explanation

A. Primary Pulmonary Hypertension 

Pregnancy is absolutely contraindicated.

Reason:

• Very high maternal mortality (30–50%).

• Increased pulmonary vascular resistance leads to right heart failure.

B. Eisenmenger Syndrome 

Also absolutely contraindicated.

Mechanism:

• Right-to-left shunt worsens during pregnancy.

• Severe hypoxemia.

• Maternal mortality 30–50%.

C. Marfan Syndrome with Aortic Root Dilatation

If aortic root diameter >40–45 mm, pregnancy is contraindicated because of risk of:

• Aortic dissection

• Aortic rupture

D. Wolff–Parkinson–White (WPW) Syndrome

WPW is not a contraindication to pregnancy.

• It is a cardiac conduction abnormality due to an accessory pathway (Bundle of Kent).

• May cause paroxysmal supraventricular tachycardia (PSVT).

• Can be managed safely during pregnancy with:

  • Vagal maneuvers

  • Adenosine

  • Beta blockers

Thus pregnancy is allowed with monitoring.
