A 35-year-old, white, 6-months pregnant woman presented to our department for hypertension. She had hypertension since 17 years. She had leg pain on excursion since 5 years. She had given birth 4 times without complications and had 2 miscarriages. Her physical examination revealed weak femoral pulses and a brachiofemoral delay. Blood pressures of right and left arm and leg were 190/110 mmHg, 140/ 90 mmHg, and 80/50 mmHg, respectively. A grade 3/6 systolic murmur was heard over the precordial and interscapular areas. The electrocardiogram was normal. Standard and Doppler echocardiographic findings revealed a coarctation of descending aorta with a maximum 84 mmHg gradient across the coarctation, which was distal to the left subclavian artery [Table/ Fig-1].MRI angiography was planned, but as the patient was pregnant and did not have serious complications nor heart failure symptoms, it was postponed to after her delivery. The patient had an uneventful pregnancy and she gave birth successfully by caesarean section without any haemodynamic complications, and the newborn was healthy. After baby's birth, the patient's blood pressure remained high. MRI angiography which was performed after birth; showed a strict coarctation of aorta (CoA) in the proximal part of the descending aorta [Table/ Fig-2]. The length of the coarctation of aorta was 14 mm, isthmus was 19 mm, smallest diameter of aortic coarctation was 6 mm, and post-coarctation aortic diameter was 28 mm.Cardiac catheterization was performed under local anaesthesia and left femoral artery and vein were cannulated. The coarctation segment could not be crossed with a 0.035 diagnostic guide wire. Therefore, a 0.014 hydrophilic guide wire was used for crossing the coarctation segment. Diagnostic multiple pores and a pigtail catheter were passed across the coarctation, over the hydrophilic guide wire. Measurements of aorta and coarctation segment were similar, as seen on MRI angiography. The maximal gradient across the coarctation was 64 mmHg. Distal part of the coarctation was minimally dilated (28 mm) [Table/ Fig-3]. Pigtail catheter was changed to a 14F, 85 cm long Mullins sheath over the 0.035 exchange guide wire. A custom made, eight-zig, 4.5 mm long CP covered stent (NuMed, Hopkinton, NY) which was loaded on a balloon in balloon (BIB) (inner balloon 12 mm × 4,5 cm, outer balloon 24 mm × 5.5 cm) was used. After attachment, the excess covering material was folded around the stent. The graft stent and balloon assembly was passed through the sheath, after checking for correct positioning. Firstly, the inner balloon was inflated and its position was rechecked by angiography and then the outer balloon was fully inflated [Table / Fig-4].Both balloons were then deflated, with the inner one being deflated first before being withdrawn through the sheath. Control aortography revealed a stent-graft in position, which covered the coarcted segment. Maximum gradient across the coarctation was 11 mmHg. The coarcted segment's diameter was increased from 6 mm to 17 mm. The proce...
