We present the case of a 65-year-old patient who developed a large posterobasal ventricular septal defect resulting from an extensive acute myocardial infarction involving the inferior and basal septum and wall. We repaired the interventricular lesion by verticalizing the cardiac apex to perform a left posterobasal ventriculotomy. We removed a great part of the residual infarcted tissue, leaving the residual scar in place. Our technique first involved creating a double-layer patch comprising heterologous pericardium and a non-collagen-impregnated Sauvage Dacron patch, fixed with single pledgeted U-stitches from the right side of the anterior septum; then we applied a third layer of heterologous pericardium on the left side of the septum in order to have only a pericardial surface in contact with blood on both ventricular sides. A running suture was used to complete the procedure from the middle to the posterior rim of the ventricular septal defect.

Abstract Background: Transcatheter ventricular septal defect closure remains a complex procedure with potential complications like complete heart block and aortic regurgitation. The ideal device design for such intervention is still evolving. Aim: To assess the safety, efficacy, and short-term outcome of ventricular septal defect closure using LifeTechTM multifunctional (KONAR-MFTM) VSD Occluder. Patients and methods: In a multicenre study, 44 patients with haemodynamically significant, restrictive ventricular septal defects underwent closure with the KONAR-MFTM device from April, 2019 to March, 2020. Clinical, echocardiographic, and angiographic data were collected and reviewed. Patients were followed up at 1, 3, 6, and 12 months. Results: The median age and weight were 8 (1.7–36) years and 20 (11–79) kg. Of 44 patients, 8 (18%) had a high muscular and 36 (82%) had a perimembranous defect, of which 6 had mild prolapse of the right coronary cusp. The median ventricular septal defect size was 8.8 (3.9–13.4) mm. A retrograde approach was adopted in 39 (88.6%) patients. Nine patients (20.5%) had a small residual leak and there was a slight increase in aortic regurgitation in one patient. One device, which embolised to pulmonary artery was retrieved, and the defect was closed with a larger device. At a median follow-up of 13 (5–18) months, the residual leak persisted in 1 (2.3%) patient. Mild aortic regurgitation in one patient remained unchanged. There were no major complications. Conclusion: Percutaneous closure of ventricular septal defect using KONAR-MFTM device is safe and effective in short and midterm follow-up including selected patients with perimembranous defect and mild prolapse of the right coronary cusp.

After a median full sternotomy, cardiopulmonary bypass is installed in the usual manner. Apical ventriculotomy is performed through the infarcted myocardium. Polypropylene pledgeted mattress sutures are passed from the right to the left ventricular side through the ventricular septal defect, with the pledgets remaining on the right ventricle. Great care must be taken to place the suture on healthy myocardium and away from the edge of the ventricular septal defect; otherwise the chances of a recurrent postoperative ventricular septal defect would increase. The sutures are subsequently positioned through a heterologous patch, previously prepared to be appropriate for the ventricular septal defect closure. A collar of 3 to 4 cm is left on the external side of the patch. A 4-0 polypropylene running suture is placed through this collar and the left ventricle to further reinforce the ventricular septal defect closure. The left ventricular incision is closed with polypropylene 3-0 continuous sutures. For each ventricular edge, the running suture is passed through 2 polytetrafluoroethylene felts: one on the endoventricular side and the other on the epicardial side. Finally, the suture line is reinforced with a continuous 2-0 polypropylene suture, which is passed through the polytetrafluoroethylene felts, the ventricular wall, and the heterologous patch used to close the ventricular septal defect.

AbstractWe describe a neonate who presented with an echogenic mass in the right atrium 8 weeks after closure of ventricular and atrial septal defects. On a routine post operative check up after discharge, a mass was detected in the right atrium on echocardiography. As a thrombotic formation was suggested, lysis was started, in combination with the administration of unfractioned heparin. As there was no change in echogenicity or size of the mass, it was surgically excised. Histopathological examination revealed a myofibroblastic inflammatory tumour.

Severe Calcification

Ventricular septal defect closure with a fenestrated patch is a recognized rescue maneuver to decrease the risk of right ventricular failure after complete repair in patients with pulmonary atresia. If the fenestration needs surgical closure, severe calcification of the patch may make it extremely difficult. We describe the closure of such a defect in a 6-year-old boy, using a double Dacron patch sandwich.
