RIOS, Mateo et al. Left chambers remodeling after repair of TAPVR connection: usefulness of NTProBNP. Arch. Pediatr. Urug. [online]. 2018, vol.89, n.1, pp.31-35. ISSN 0004-0584.

Total anomalous pulmonary venous return is a congenital heart disease characterized by failure of connection between the primitive left atrium and the pulmonary venous return, the latter drains to the systemic venous return trough persistent embryologic connections. In this pathology there is a normal size, but rather small, left ventricle with a small and undeveloped left atrium. In the postoperative period, the left chambers must handle all the pulmonary venous return, which could mean an increased wall stress.

The study presents two cases of Total Anomalous Pulmonary Venous Return, and the behavior of left atrial size and natriuretic peptide level after surgery. We set a hypothesis by which a dysfunction in the filling of the left chambers could explain this phenomenon and how this triggers compensatory modifications. Analyzing the level of natriuretic peptide might help monitor this process.
