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.
