Percutaneous closure of a large atrial septal defect presenting with acute severe hemolysis

Hemolysis induced by occlude devices to repair the structural cardiac defects is not very infrequent in intervention cardiology. The unavoidable residual leaks, which are featured by high velocity, vortices, and rapid deceleration, impose significant shear on red blood cells leading to hemolysis [1, 2]. There are several cases that reported acute hemolysis after transcatheter closure of VSD or PDA in the literature [3, 4]. However, hemolysis due to intracardiac device for ASD closure is rather rare. Although in some cases surgical removal of the device or transcatheter occlusion of a residual shunt may be necessary, most hemolysis can be conservatively managed with fluids, sodium bicarbonate, and corticosteroids.
A 51-year-old female weighing 54 kg was admitted to the catheter lab with the aim of performing a transcatheter device closure of ASD. She presented a 2-year history of exertional chest distress. The second heart sound was prominent, and a grade 3/6 systolic murmur was...
