    ABSTRACT: The Warden procedure was introduced for surgical repair of partial anomalous pulmonary venous connection to the higher portion of the superior vena cava in an attempt to decrease the incidence of postoperative sinoatrial node dysfunction and pulmonary venous obstruction. However, postoperative cavoatrial channel stenosis and obstruction up to 20% and 10%, respectively, requiring catheter intervention has been reported. In this article, we describe a modified cavoatrial anastomotic technique to avoid postprocedural superior vena cava stenosis.

    ABSTRACT: Multiple muscular ventricular septal defects treated with a single device have been reported before, but the way of choosing a suitable occluder is not well described. Implantation of an oversized device might lead to potential side effects. We described our experience with a single device to close two nearby muscular ventricular septal defects perventricularly, and specifically the decision-making process used to choose the suitable occluder.

    ABSTRACT: Both surgical repair and transcatheter closure of isolated ventricular septal defects are known to have limitations in children. This report describes the short-term results of perventricular device closure of nonmuscular ventricular septal defects without cardiopulmonary bypass in young children. Thirty patients who had nonmuscular ventricular septal defects underwent perventricular closure by minimally invasive technique without cardiopulmonary bypass. A subxiphoid minimally invasive incision was performed. Under the continuous guidance of transesophageal echocardiography, the free wall of the right ventricle was punctured and a guidewire was introduced into the left ventricle through the defect. A delivery sheath was advanced over the wire and through the defect into the left ventricle. The device was released. Closure was successful in 27 patients (90%). There was no mortality or atrioventricular block perioperatively or during the entire follow-up period. Three patients developed incomplete right bundle branch blocks and seven patients developed new trace or mild tricuspid regurgitation after the closure. The mean hospital stay was 3.6 +/- 0.7 days (range, 3 to 5 days) and no patient needed any blood or blood products. Follow-up at 6 months showed that two of the three patients had persistent incomplete right bundle branch block and three of the seven patients had persistent closure-related trace or mild tricuspid regurgitation. Perventricular device closure of isolated ventricular septal defects without cardiopulmonary bypass appeared to be safe and efficacious in selected young children. The outcomes of short-term follow-up are acceptable.
