Use of supra-therapeutic phenytoin for management of ventricular arrhythmias in children: Case series and literature review.

Phenytoin is a versatile drug with utility in neurological, dermatological, and even cardiac disease processes. Though phenytoin is widely available due to its excellent anti-epileptic properties, it is now rarely used as an antiarrhythmic. Phenytoin has well-studied sodium-channel blocking abilities which can be taken advantage of to treat ventricular arrhythmias.

Approach to Wide Complex Tachycardia in Paediatric Patients.

Wide complex tachycardia (WCT) is an infrequently encountered condition in paediatric patients and may be due to a variety of causes including supraventricular tachycardia with aberrant conduction, ventricular activation via an accessory pathway, ventricular pacing, or ventricular tachycardia. Immediate tachycardia termination is required in haemodynamically unstable patients. After stabilization or in those with haemodynamically tolerated WCT, a careful review of electrocardiographic tracings and diagnostic manoeuvres are essential to help elucidate the cause.

A novel technique of single patch repair of right partial anomalous pulmonary venous return to the superior vena cava by right atrial edge rotation.

In patients with partial anomalous pulmonary venous return of the right superior pulmonary veins to the superior vena cava, surgical repair generally consists of either intraatrial baffle with or without caval enlargement, or superior caval transection and cavoatrial anastomosis to the right atrial appendage. We discuss here a novel technique of superior caval enlargement without need for patch material or reimplantation.

Double-barrel right ventricular outflow: tetralogy of Fallot annulus preservation technique.

In patients with tetralogy of Fallot (TOF) repair and a borderline pulmonary valve annulus (PVA) size, surgical repair often necessitates a transannular incision and subsequent placement of a patch with or without a monocusp or, alternatively, a right ventricle-to-pulmonary artery conduit. We discuss here a technique in which the pulmonary valve annulus can be safely preserved, with infrequent postoperative issues as well as the potential for less incidence of right ventricular outflow intervention in the long term.

Update on the Amplatzer duct occluder: a 10-year experience in Asia.

Few data exist regarding the efficacy and safety of the Amplatzer ductal occluder (ADO) type 1 device in the Asian region. This retrospective study, conducted between August 2001 and April 2011, attempted device placement for 231 patients (165 females and 66 males) with a median age of 7.4 years (range, 3 months to 64 years) and an average weight of 19.
