Staged ventricular recruitment in patients with borderline ventricles and large ventricular septal defects

Abstract

Staged ventricular recruitment via ASD restriction without VSD closure is associated with growth of the hypoplastic ventricle. In patients who are deemed high-risk for single ventricle, this approach might facilitate eventual biventricular conversion. Further studies are needed to identify optimal candidates for this approach.

Repair of double outlet right ventricle: Midterm outcomes

“…This approach is similar to that described previously for repair of borderline left heart and unbalanced CAVC defects that demonstrated that gradual loading of hypoplastic ventricles promote growth of the LV. [10][11][12] This study suggests that staged BiV repair following initial palliation in this subgroup is associated with survival and reintervention rate similar to primary BiV repair at midterm follow-up. Longerterm follow-up will be necessary to determine survival, quality of life, and need for reinterventions.…”

From Fontan to Anatomical Repair 16 Years Later

“…Techniques for LV recruitment have been proposed. 3 Previous reports demonstrated the feasibility of this conversion, often in the first 3 years of life. 4,5 In our patients, the management was also debatedespecially in the second case.…”

Atrioventricular valve surgery: Restoration of the fibrous skeleton of the heart

“…2 A recently proposed strategy of biventricular recruitment and conversion has been described, but early results appear similar to those achieved with conventional single ventricular palliation, and long-term follow-up is lacking. 19 In patients with balanced ventricles who undergo complete repair, the risk of AVV reoperation is approximately 25% at 20 years. 11 Conversely, in patients with unbalanced AVSD, the rate of AVV reoperation is in the range of 40% to 50% at 25 years follow-up.…”
