A study of narrow QRS tachycardia with emphasis on the clinical features, ECG, electrophysiology/radiofrequency ablation.

Atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) are the most common forms of paroxysmal regular supraventricular tachycardias. The clinical, ECG and electrophysiological findings of 121 patients with narrow QRS tachycardia were evaluated prospectively. A total of 75 (62%) of the patients had AVNRT while 46 (38%) had AVRT.

Transcatheter device closure of perimembranous ventricular septal defect in children treated with prophylactic oral steroids: acute and mid-term results of a single-centre, prospective, observational study.

Unlabelled: Background and Objective Although transcatheter closure of perimembranous ventricular septal defect is emerging as an accepted, viable alternative, conduction disturbances still remain a major concern. Although steroid treatment has shown encouraging results with complete recovery, efficacy of prophylactic use of steroids is still speculative. We aim to study the mid-term outcome of perimembranous ventricular septal defect closure in children who received prophylactic oral steroids.

Clinical and angiographic follow-up of coronary artery fistula interventions in children: techniques and classification revisited.

Background: Transcatheter closure of coronary artery fistula has emerged as a safe and effective alternative to surgery. However, follow-up angiographic data after closure of the coronary artery fistula is extremely limited. We report our clinical and angiographic follow-up of children who underwent either transcatheter or surgical closure.

Local Anaesthesia Suppressing Idiopathic Ventricular Tachycardia: - A Cause of Non-inducible Arrhythmia During Electrophysiology Study.

A 13 year old boy having idiopathic ventricular tachycardia had non-inducible tachycardia twice on electrophysiology (EP) study due to suppression of arrhythmia by local anaesthetic agent, lignocaine. This case report demonstrates a cause of non-inducibility or arrhythmia during EP study and effect of lignocaine in suppression of idiopathic ventricular tachycardia.

Successful transcatheter closure of coronary artery fistula in a child with single coronary artery: a heavy load and a long road.

Single coronary artery is an uncommon variation of the coronary circulation. After transposition of great arteries, coronary artery fistulas are the most common associated cardiac anomalies in these patients. Transcatheter closure of coronary artery fistula (CAF) involving single coronary artery is a challenging intervention.

Perventricular device closure of isolated muscular ventricular septal defect in infants: a single centre experience.

Objectives: To evaluate prospective single centre experience of mid-term safety and efficacy of perventricular device closure of isolated large muscular ventricular septal defect (mVSD) in high-risk infants.

Background: Surgical closures of large mVSD in infants represent a challenge with significant morbidity.

Methods: Between August 2008-2010, perventricular closure was attempted in 24 infants of 6.
