Figure 3 Intraoperative findings of myocardial ruptureWhite arrows indicate a 1-cm myocardial rupture on the right atrial wall between the inferior vena cava and the tricuspid annulus. A) Right atrium. B) Right ventricle. C) Inferior vena cava. D) Cranial side. E) Caudal side. The surrounding myocardium appears darkly charred, consistent with thermal coagulation necrosis rather than a purely mechanical tear.
