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

AbstractA 13year 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

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 6.01 ± 2.37 months age and 4.27 ± 0.56 kg weight under TEE guidance. Results: The device was successfully deployed in 21/24 infants. Size of mVSD was 8.42 ± 1.46 mm (6.1–12 mm). Mean procedure time was 28.8 ± 11.7 min. The closure rate was 84% immediately and 100% at 6 months. Four patients suffered major complications: 2-died, 1-esophageal perforation, 1-persistent CHB. At 26.23 ± 6.63 months follow-up two patients were symptomatic: 1-required device retrieval, 1-died of severe gastroenteritis. Conclusion: Perventricular device closure of isolated mVSD appears feasible option at mid-term follow-up and may either substitute or complement the conventional surgical technique in selected cases depending on institutional paediatric cardiac surgery performance
