High ventricular septal defects, intracrural or subdry ventricular septal defects are located higher due to their proximity to the right ventricular outflow tract. The infra-dry ventricular septal defect cannot be surgically occluded. For intracrural defects, a small incision can be made to seal the defect when it is less than 10 mm. Since the defect is adjacent to the right coronary valve of the aorta, an eccentric occluder must be used, which is not possible with medical occlusion. This morning we performed a surgical small-incision occlusion of an intracricoid ventricular septal defect, monitored with transesophageal ultrasound. I measured the size of the defect at 6 mm preoperatively, and we chose a size 7 eccentric occluder. The protruding umbilical bubble of the left ventricular surface was to be placed in the apical region during the sealing process, so this was the focus of ultrasound observation.
