ABSTRACT
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. Our database revealed 62 surgically treated vascular ring patients between 1993 and 2014. Double aortic arch was the most common diagnosis (53%). Median age at operation was 1 year. Symptoms were mainly respiratory (89%) and feeding problems (32%). Median extubation time and hospital stay were 4 h and 5 days. Mean follow-up was 7.8 ± 5.8 years. Early mortality was 8% and was related to anatomical diagnosis, concomitant anomalies, and a need for preoperative intubation. Freedom from residual symptoms at 1 and 6 months was 63 and 82%, respectively. Freedom from inhalation therapy at the last follow-up was 82% and was influenced by a type of vascular ring and preoperative ventilation. Dysphagia symptoms always disappeared. CONCLUSION: Surgical relief of tracheoesophageal compression is commonly effective in vascular ring anomalies. Respiratory symptoms necessitating chronic inhalation therapy only persist in a minority of children. Patients with double aortic arch are at increased risk to remain symptomatic, particularly with infectious exacerbations.

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 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. Mitral annulus-ventricular tachycardia, a rare form of idiopathic left VT, can safely and successfully be ablated in very young children.
