Left ventricular outflow tract obstruction after repair of atrioventricular septal defect

Open full text 1 citations

Abstract

We read with interest the article by Chandiramani and colleagues1 on left ventricular outflow tract obstruction (LVOTO) after repair of complete atrioventricular septal defect (cAVSD). They observed that the subaortic area is intrinsically narrow in patients with cAVSD, and that the narrowing becomes more severe after complete repair, both with 2-patch and modified single patch (MSP) techniques. They noted that MSP technique was associated with a greater decrease in the subaortic diameter compared with the 2-patch technique.
