  8. Atrial Septal Defect – Class I • Surgical or percutaneous closure of an atrial septal defect (ASD) is indicated in the presence of a hemodynamically significant ASD with or without resulting symptoms. (Level of Evidence: B) • In patients with large secundum ASDs (>38 mm) not amenable to device closure, surgical closure should be undertaken (Level: B) • Patients with a sinus venosus defect or ostium primum ASD cannot be closed by percutaneous devices and should be surgically repaired by congenital heart surgeons (Level: C) Presentation at Annual CCS Meeting in Edmonton 2009

  9. Atrial Septal Defect – Class I • If atrial fibrillation/flutter occurs, anticoagulation is indicated in accordance with existing guidelines (Level: A) • Atrial arrhythmias can be managed with either rate or rhythm control strategies and the approach should be tailored to the individual patient (Level: B) Presentation at Annual CCS Meeting in Edmonton 2009

  10. Atrial Septal Defect – Class III • If PAH is present and there is irreversible PAH, the ASD should not be closed. Such patients should receive care from a specialist with expertise in PAH.

The preferred approach should reflect center expertise and patient preference (Level of Evidence: B) • For significant re-coarctation post repair, a percutaneous approach (if the anatomy is suitable) is the preferred initial intervention (Level of Evidence: B) • Surgeries and percutaneous interventions should be performed in centres and by individuals with expertise in the procedure (Level of Evidence: C) Presentation at Annual CCS Meeting in Edmonton 2009

  28. RIGHT VENTRICULAR OUTFLOW TRACT OBSTRUCTION (RVOTO) Class I • In symptomatic patients with valvular RVOTO, a domed pulmonary valve and peak instantaneous Doppler gradients > 50 mmHg or mean echo gradients > 30 mmHg, balloon valvotomy is recommended (Level of Evidence: C) • In asymptomatic patients with valvular RVOTO, a domed pulmonary valve and peak instantaneous Doppler gradients > 60 mmHg or mean gradients > 40 mmHg, balloon valvotomy should be considered (Level of Evidence: C) Presentation at Annual CCS Meeting in Edmonton 2009
