case_images: Electrocardiogram (Figure 1A) revealed sinus rhythm, left deviation of the electrical axis, third-degree atrioventricular block, and complete left bundle branch block, accompanied by ST-T changes. The diameter of the residual interventricular septal defect was 3 mm, and continuous suturing with a pericardial patch was performed (Figure 1B). After the surgery, a temporary epicardial pacemaker was implanted, and isoproterenol was administered continuously (Figure 1C). The heart rhythm gradually recovered after 3 days (Figure 1D) and was maintained throughout the 45 months of follow-up.
