Repair of tetralogy of Fallot with atrioventricular septal defect may be associated with hemodynamic challenges in the postoperative period particularly as left atrial hypertension secondary to left atrioventricular valve dysfunction may exacerbate pulmonary regurgitation and augment low cardiac output. We present a case describing hybrid strategies to treat severe left atrioventricular and pulmonary valve regurgitation with modified balloon expandable stent valves to counter low cardiac output secondary to valve dysfunction. Such strategies offer an alternative to standard valve choices and should be considered as an extension of the current surgical valve inventory.

The optimal timing for pulmonary valve replacement after Tetralogy of Fallot (TOF) repair remains controversial. In this study, we estimated the feasibility of using flow energy loss (FEL) to predict right ventricular (RV) deterioration due to pulmonary regurgitation after TOF repair. We examined RV outflow tract (RVOT) flow in nine patients who underwent TOF or double-outlet right ventricle repair in the intervention group (Group I) and compared them with three healthy children in the control group (Group C).

Infants with single ventricle physiology typically undergo cardiac catheterization prior to superior cavopulmonary anastomosis (SCPA) to assess operative suitability. Predictors of poor outcome at sea level include elevated pulmonary artery pressure (mPAP), indexed pulmonary vascular resistance (PVRi), age <3 months, significant atrioventricular valve regurgitation, among others. Increased altitude has vasoconstrictive effects on the pulmonary vasculature, which may affect pre-SCPA hemodynamics and outcomes.

Endothelial-to-mesenchymal transition (EndoMT) is a cellular process often initiated by the transforming growth factor β (TGF-β) family of ligands. Although required for normal heart valve development, deregulated EndoMT is linked to a wide range of pathological conditions. Here, we demonstrate that endothelial fatty acid oxidation (FAO) is a critical in vitro and in vivo regulator of EndoMT.

Nikaidoh vs Réparation à l'Etage Ventriculaire vs Rastelli.

Semin Thorac Cardiovasc Surg Pediatr Card Surg Annu 2018 Mar;21:58-63
Mark G Hazekamp, Timofey Nevvazhay, Vladimir Sojak
This review describes the different surgical options for transposition of the great arteries, ventricular septal defect (VSD), and left ventricular outflow tract obstruction. When the pulmonary valve can be used, an arterial switch operation with VSD closure and resection of pulmonary stenosis may be possible. This is not the scope of our review: we focus on the Rastelli, REV (Réparation à l'Etage Ventriculaire), and Nikaidoh techniques, and we also describe the "en bloc rotation" technique.

Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare complex cyanotic congenital heart disease with heterogeneous morphological variation. Prenatal diagnosis allows for developing a safe plan for delivery and postnatal management. While transthoracic echocardiography allows for detailed delineation of the cardiac anatomy, additional imaging modalities such as computed tomography, magnetic resonance imaging, and catheterization may be necessary to further outline features of the cardiac anatomy, specifically coronary artery anatomy.
