Percutaneous ventricular septal defect closure causing acute aortic regurgitation

Intravascular hemolysis and aortic regurgitation (AR) are rare complications of transcatheter closure of perimembranous ventricular septal defects. The current study reports a case of an acute AR, which resulted from acute right coronary cusp perforation by the ventricular septal defect occluder. The current manuscript discusses the possible causes of early cusp erosion owing to occluder, advantages of early operation in such cases, and role of thorough perioperative transesophageal echocardiography in identifying acute AR.
