Miniinvasive interventional bridge to major surgical repair of critical aortic coarctation in a newborn with severe multiorgan failure.

Abstract

We present a case of a severely ill newborn with complex coarctation, multiorgan failure and massive oedema, who was treated with emergency stenting of the isthmus on the second day of life, which was followed by surgical stent removal and repair of the arch on the 29th day, after stabilization of his general status. Interventional percutaneous direct stent implantation was performed, using a coronary stent (Abbott Multi-Link Vision Coronary Stent 3.5 mm/15 mm, USA) to cover the area of the aortic isthmus in the newborn. The area from the origin of the left subclavian artery to the beginning of the descending thoracic aorta beneath the isthmus was widely expanded. Control angiography showed normal size of the isthmus without a systolic gradient in the area. In the next 3 weeks the boy improved his general status, with normalization of liver and renal parameters, as well as resolution of the oedema, and underwent surgery on his 29th day of life. The procedure of stent removal with aortic extended end-to-end anastomosis was performed without complications, and the infant was transferred to general paediatrics for further treatment. The strategy of miniinvasive interventional bridge to postpone major surgical repair was effective in the presented infant, with positive final results of both cardiological intervention and subsequent surgical repair.
