We describe a novel technique that allows controlled and precise delivery of single or multiple coils simultaneously for occlusion of a coronary artery fistula using a bioptome passed via a long sheath positioned at the distal end of the fistula. The fistula was balloon occluded distal to the take-off of the native branches before, during and after coil delivery in two patients.
We report a case of massive spontaneous primary chylopericardium in a 2-month-old infant who was successfully treated with thoracic duct ligation and creation of a posterior pericardial window.

Residual ventricular septal defect after surgical repair for tetralogy of Fallot can occasionally be hemodynamically important requiring re-intervention. Transcatheter closure using ventricular septal defect devices is an attractive option for such defects. We describe two such cases where the Amplatzer duct occluder was used as an innovative, less costly alternative for closure of residual membranous ventricular septal defects. Complete occlusion of the residual ventricular septal defect with significant symptomatic improvement could be accomplished in both patients.
