Résumé
Atrioventricular valve regurgitation (AVVR) is present in up to 75% of Fontan patients, and it is associated with an increased risk of Fontan circulation failure, morbidity, and mortality. Traditional treatment options include surgical repair vs. surgical replacement. We present, to the best of our knowledge, one of the first cases of successful trans-catheter repair of severe common AVVR using the MitraClip device. A 20-year-old male with a history of double-outlet right ventricle (DORV) with unbalanced common atrioventricular canal to the right ventricle, severely hypoplastic left ventricle, and total anomalous pulmonary venous return status post-Fontan procedure presented with progressively worsening dyspnoea on exertion. Transoesophageal echocardiogram demonstrated severe common AVVR. After discussion of the case during the adult congenital heart disease multidisciplinary conference, patient underwent successful placement of two MitraClip devices, reducing the regurgitation from torrential to moderate. MitraClip therapy can be used to alleviate symptoms in patients deemed as high risk for surgery. However, careful attention must be paid to haemodynamics before and after clip placement, which may predict short-term clinical outcomes.

Case summary
UNASSIGNED
A 20-year-old male with a history of double-outlet right ventricle (DORV) with unbalanced common atrioventricular canal to the right ventricle, severely hypoplastic left ventricle, and total anomalous pulmonary venous return status post-Fontan procedure presented with progressively worsening dyspnoea on exertion. Transoesophageal echocardiogram demonstrated severe common AVVR. After discussion of the case during the adult congenital heart disease multidisciplinary conference, patient underwent successful placement of two MitraClip devices, reducing the regurgitation from torrential to moderate.
Discussion
UNASSIGNED
MitraClip therapy can be used to alleviate symptoms in patients deemed as high risk for surgery. However, careful attention must be paid to haemodynamics before and after clip placement, which may predict short-term clinical outcomes.
