Aortic Coarctation Diagnosed During Pregnancy in a Woman With Repaired Tetralogy of Fallot.

Aortic coarctation is thought to be a rare condition in patients with tetralogy of Fallot. We report the case of a 26 year old woman presenting with systemic hypertension at 17 weeks of pregnancy after repair of tetralogy of Fallot in childhood. Echocardiography and magnetic resonance imaging revealed right aortic arch with severe isthmic coarctation. Her blood pressure was controlled medically during the rest of her pregnancy, and delivery was uneventful. Successful transcatheter placement of a covered stent at the level of the coarctation was performed after delivery. To our knowledge, this is the first reported case of aortic coarctation diagnosed in an adult patient late after repair of tetralogy of Fallot.
