Preliminary surgical experience of minimally invasive device closure of perimembranous ventricular septal defects
Online published: 2013-02-06
Objective To summarize the clinical experience of minimally invasive perventricular device closure of perimembranous ventricular septal defects (VSD), and explore the surgical techniques and indications. Methods Forty-eight patients with perimembranous VSD underwent perventricular device closure with inferior sternotomy. Restrictive perimembranous VSD were found in all the patients. The basal diameters of VSD ranged between 2 mm and 9 mm, and the diameters of the occlusion device waist ranged between 4 mm and 10 mm. Concentric occluders were used in 45 patients, and eccentric occluders were used in 3 patients. The occlusion device was deployed through right ventricle under echocardiographic guidance. Results Forty-five patients were stable in heart function after operation. Patients were followed up for 1 to 6 months, and there was no position shift of the occlusion devices, arrhythmia or residual shunt. Arrhythmia occurred in the other 3 patients after operation, including ventricular premature beat in 1 patient and atrioventricular block in the other 2 patients. All of these three patients recovered after treatment. Conclusion The perventricular device closure of perimembranous VSD with inferior sternotomy appears to be a favorable choice for the treatment of VSD, while the surgical indications should be carefully managed.
