A Case Report of Restrictive Ventricular Septal Defect & Left Ventricular Out Flow Tract Stenosis Caused by Fibrotic Tissue in Tetralogy of Fallot / 대한흉부외과학회지

ABSTRACT

The VSD in TOF is usually large and unrestrictive with an equal to or greater than that of the aortic annulus. Typically shunting through the VSD is bidirectional or right-to-left component. Restrictive VSD in TOF caused by ingrowing fibrotic tissue is very rare. We report a case of restrictive VSD and LVOTO in TOF caused by ingrowing fibrotic tissue with the review of literature.
