Perventricular device closure of muscular ventricular septal defects on the beating heart: technique and results.

摘要: Abstract Objective Both surgical management and percutaneous device closure of muscular ventricular septal defects have drawbacks limitations. This report describes our initial experience with intraoperative without cardiopulmonary bypass in 6 consecutive patients. Methods A median sternotomy or a subxiphoid minimally invasive incision was performed. Under continuous transesophageal echocardiographic guidance, the right ventricle free wall punctured, wire introduced across largest defect. The Amplatzer (AGA Medical Corporation, Golden Valley, Minn) defect occluding (a self-expandable double-disk device) used. An introducer sheath fed over wire, tip positioned left cavity. then advanced inside deployed by retracting sheath. Associated cardiac lesions, if any, can be repaired during bypass. similar technique also applied for periatrial complex atrial defects. Results patients are presented. Cardiopulmonary not needed any patient placement 4 repair concomitant malformations only (double-outlet ventricle, aortic arch hypoplasia, pulmonary artery band removal). No complications from using this occurred. Discharge echocardiograms showed no significant shunting septum. Conclusions Perventricular multiple is safe effective. We believe that could become treatment choice infant child associated
