Stents as Bridge to Arterial Switch Operation for D-Transposition of Great Arteries Late Presenter
We report a 5-month-old infant with dextro-transposition of great arteries (D-TGA) with intact ventricular septum (IVS) who had low left ventricular mass index, small patent ductus arteriosus (PDA), and stretched patent foramen ovale. The patient had respiratory failure due to pneumonia. The surgical intervention was considered very high risk. Thus, the patient underwent PDA stenting with balloon predilation technique followed by atrial septal stenting with false impression of dislodgement—“pseudo-dislodgement” because of inadvertent retraction of patent foramen ovale that was confirmed by transthoracic echocardiography guidance. After the procedure, the left ventricular mass index improved and patient was planned for arterial switch operation. The combined approach of PDA and atrial septal stenting may provide potential nonsurgical method of ventricular preparation for D-TGA/IVS late presenter, acting as a bridge to arterial switch operation especially those living in remote areas.
