Background: In five patients, an apical muscular septal defect was closed in a hybrid approach using the Amplatzer® duct occluder during open heart surgery, whereas concomitant defects were treated surgically. In addition to their different heart defects that needed surgery, all had a muscular ventricular septal defect in the apex of the heart, poorly accessible for traditional, surgical approach. We describe the method and outcome in these patients. Methods: The tip of a forceps was advanced from the left into the right ventricle through the ventricular septal defect. The delivery sheath was caught under visual control in the right ventricle and pulled back into the left ventricle. The disc was developed and pulled back until it was felt tugging at the septum. Then the core was developed. The end of the device was visible in the right ventricle and was secured with a Prolene® suture. Results: The procedures were event-free. During early follow-up there were either no or only insignificant shunts in the region of the prior trabecular defects in four patients. The unsatisfactory result in the last patient was caused by inaccurate preoperative assessment. Conclusion: The method seems valuable in patients in need of other intracardiac surgery. © 2010 Wiley-Liss, Inc.
