Early and late outcomes after surgical management of congenital vascular rings.

Unlabelled: Persistent respiratory or feeding problems in children may be associated with a congenital vascular ring. Surgical management is fairly standardized, but long-term outcomes are not well described. This study aims to investigate clinical presentation, surgical treatment, and risk factors for early mortality and late outcome.

Effective cardioverter defibrillator implantation in children without thoracotomy: a valid alternative.

The implantation method for a cardioverter defibrillator in children is poorly standardized because of obvious features related to size and predisposing cardiac disease in children presenting with malignant ventricular arrhythmia. We propose an alternative method of implanting a cardioverter defibrillator without the need for associated thoracotomy, based on the subxiphoidal insertion of an epicardial bipolar ventricular pacing and sensing lead, an active can placed in the abdomen, and a subcutaneous array tunneled along the left thoracic wall as a shock electrode. This technique offers the advantage of an effective and minimally invasive implantable cardioverter defibrillator with wide applicability for children, independent of their size and cardiac status.

Ablation of an idiopathic left ventricular tachycardia originating from the posterior mitral annulus in a toddler.

Ablation of a mitral annulus (MA)-ventricular tachycardia (VT), a rare form of idiopathic left VT, has not yet been described in patients <2 years of age. We describe a case of a toddler with an incessant, poorly tolerated idiopathic VT (190 bpm) refractory to medical therapy, which was successfully ablated in the left ventricle at the infero-posterior part of the MA. Different diagnostic and ablation steps are described.
