Therapeutic Recommendations for Atrioventricular Septal Defect
| Class I |
| 1. Surgery for severe left atrioventricular valve regurgitation is recommended per GDMT indications for mitral regurgitation.(Level of Evidence: C-LD) |
| 2.Surgery for primary repair of atrioventricular septal defect or closure of residual shunts in adults with repaired atrioventricular septal defect is recommended when there is a net left-to-right shunt (Qp:Qs ≥1.5:1), PA systolic pressure less than 50% systemic and pulmonary vascular resistance less than one third systemic.
(Level of Evidence: C-EO) |
| Class IIa |
| 1.Operation for discrete LVOT obstruction in adults with atrioventricular septal defect is reasonable with a maximum gradient of 50 mm Hg or greater, a lesser gradient if HF symptoms are present, or if concomitant moderate-to-severe mitral or AR are present. (Level of Evidence: C-EO) |
| Class IIb |
| 1.Surgery for primary repair of atrioventricular septal defect or closure of residual shunts in adults with repaired atrioventricular septal defect may be considered in the presence of a net left-to-right shunt (Qp:Qs ≥1.5:1), if PA systolic pressure is 50% or more systemic, and/or pulmonary vascular resistance is greater than one third systemic. (Level of Evidence: C-EO) |
2008 ACC/AHA Guidelines for the Management of Adults With Congenital Heart Disease (DO NOT EDIT)[2]
Recommendations for Surgical Therapy (DO NOT EDIT)[2]
| 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)" |
