Chest injury is an acute, extremely life-threatening condition. Among penetrating heart wounds, approximately 85% are stab wounds. In the case of stab and cut injuries, the lethality, according to various sources, reaches 90% and directly depends on the time of delivery of the victim to the hospital. In the overwhelming majority of cases, emergency operations for stab wounds of the chest are conducted in general surgical hospitals. As a rule, when providing emergency surgical care, only superficial heart wounds are sutured, excluding the correction of damage to the intra-cardiac structures. Aorto-right atrial fistula is a rather rare clinical condition that is formed due to the action of a traumatic factor and is characterised by the formation of a communication between the aorta and the right atrium with the discharge of arterial blood into the venous system. Considering that this pathology is accompanied by an increase in pressure in the right atrium, signs of stagnation are found in the systemic circulation, followed by compensatory dilatation of the right atrium and then dilatation of the right ventricle. The only effective method to treat this problem is surgery.The presented clinical case demonstrates the surgical treatment of chronic post-traumatic aorto-right atrial fistula, pseudo-aneurysm between the non-coronary sinus and the right atrium and pseudo-aneurysm of the left coronary sinus 2 years after the stab wound. Echocardiography performed after surgery indicated a positive trend, i.e., a decrease in the size of the right- and left-sided heart and normalisation of pressure in the pulmonary artery. No inter-chamber shunts were found. This case shows that clinicians must remember that after providing emergency surgical care to patients with penetrating chest wounds, it is necessary to conduct an additional examination of the heart after stabilisation of the condition to detect hidden damage to the intra-cardiac structures.Received 2 February 2021.
