[Good results after closure of a arterial septal defect during heart catheterisation instead of surgery].

OBJECTIVE: Evaluation of the first results in the Netherlands of percutaneous and transvenous closure of an ASD II in children with an Amplatzer Septal Occluder (ASO). DESIGN: Prospective. METHOD: Data were collected from children with an ASD II prior to, during and up to 24 months after the insertion of an ASO during heart catheterisation in Leiden University Hospital, the Netherlands. RESULTS: Between 1 January 1998 and 29 February 2000, 28 patients (12 girls, 16 boys; mean age: 74 months (range: 15-198 months)) underwent heart catheterisation to close an ASD II with an ASO. In 26 patients an ASO could be placed without significant complications. The size of the device varied from 9-34 mm (median 16 mm). In one patient ASD closure was not attempted because of multiple ASDs. In another patient the procedure was stopped after air embolism into the coronary arteries had occurred during preparation of ASO implantation. In 23/26 patients with an implanted ASO, no residual shunt was present after 24 hours. One child, in whom the defect was found to be closed after 24 hours and after three weeks, returned abroad and was lost to follow-up. After one year all defects (n = 22) were completely closed. CONCLUSION: Percutaneous transvenous closure of an ASD II with an ASO was possible, was not associated with any significant complications and had a high success rate, even in relatively young children with large defects.

Atypical form of atrioventricular septal defect without left axis deviation: relation between morphology and unusual QRS axis.

OBJECTIVE: To clarify the morphological features relating to an intermediate axis or a right axis deviation in atrioventricular septal defect (AVSD). SUBJECTS: 135 patients with typical AVSD and with nine patients with atypical AVSD, characterised by a well formed atrial septum, a milder downward displacement of the atrioventricular valves, and a shorter length of the ostium primum defect. MAIN OUTCOME MEASURES: Relation between morphology and electrocardiographic and vectorcardiographic findings; prevalence of Down's syndrome and of other cardiac anomalies. RESULTS: All nine patients with atypical AVSD had an unusual mean frontal QRS axis compared with six of the 135 patients (4%) with typical AVSD (p < 0.01). All eight patients who underwent the vector analyses showed atypical movement of the QRS loop--that is, an initial left inferior movement in the frontal loop (eight patients) and counter-clockwise rotation in the sagittal loop (seven). The corresponding values for 119 patients with typical AVSD were 20 and 22 patients (p < 0.01). Seven patients with atypical AVSD (78%) and 55 (41%) with typical AVSD had Down's syndrome (p < 0.05). None of the twenty one patients with additional cardiac anomalies had atypical AVSD, an unusual QRS axis, or unusual movement in the QRS loop. CONCLUSIONS: The atypical morphology, supposedly related to the degree of posteroinferior displacement of the conduction system, was one of the causes of unusual movement of the QRS loop in AVSD.
