If it ruptures on the intraventricular septum, it can create a ventricular septal defect. Other causes of cardiac tamponade may also require surgical intervention, although emergent treatment at the bedside may be adequate. It should also be determined whether the patient had a history of a repaired congenital heart disease as they often have complex cardiac anatomy with artificial grafts and shunts that may sustain damage, leading to acute decompensated heart failure.
