ACC / AHA Guidelines- Recommendations for Surgical Therapy (DO NOT EDIT)

Class I

1. Surgeons with training and expertise in CHD should perform operations for AVSD. (Level of Evidence: C)

2. Surgical reoperation is recommended in adults with previously repaired AVSD with the following indications: a. Left AV valve repair or replacement for regurgitation or stenosis that causes symptoms, atrial or ventricular arrhythmias, a progressive increase in LV dimensions, or deterioration of LV function. (Level of Evidence: B) b. LVOT obstruction with a mean gradient greater than 50 mm Hg or peak instantaneous gradient greater than 70 mm Hg, or a gradient less than 50 mm Hg in association with significant mitral regurgitation or AR. (Level of Evidence: B) c. Residual/recurrent ASD or VSD with significant left-to-right shunting (refer to Section 2.0, Atrial Septal Defect, and Section 3.0, Ventricular Septal Defect). (Level of Evidence: B)
