Closure of small fenestrations without optimal rims with a PDA coil far from primary atrial septal defects: a new approach.

An ostium secundum atrial septal defect (ASD) is a CHD that can be treated percutaneously since 1974, mostly cases with only one main defect. In cases with fenestrations close to the main defect, a single occluder can be used for treatment because the discs extend beyond the waist of the device. In some cases where the defects are far from each other, they may require either more than one device or surgical closure.

Transcatheter Resolution of a Failed Neoconfluence in Pulmonary Atresia With Discontinuous Pulmonary Arteries.

We present a case of a full-term newborn with complex congenital heart defects, including single-ventricle physiology and discontinuous pulmonary arteries. Prompt surgical intervention was performed, which involved pulmonary neoconfluence with autologous pericardium graft and systemic-to-pulmonary shunt placement. However, postoperative complications required stenting to address pulmonary artery stenosis.

Percutaneous transient occlusion of the transtricuspid flow: a new method to evaluate the right ventricle-dependent coronary circulation in pulmonary atresia with intact ventricular septum.

Pulmonary atresia with an intact ventricular septum is characterised by heterogeneity in right ventricle morphology and coronary anatomy. In some cases, the presence of ventriculocoronary connections may promote coronary artery stenosis or interruption, and aortic diastolic pressure may not be sufficient to drive coronary blood flow. This requires a correct evaluation (currently done by angiography) which depends on whether the patient can be offered decompression of the right ventricle.
