Abstract
<jats:p>Introduction. Aortopulmonary window is an abnormal communication between the ascending aorta and the pulmonary trunk in the presence of two independent aortic and pulmonary valves. This congenital defect results from a disturbance in the embryonic development of the aortopulmonary trunk and is typically located in the proximal ascending aorta on its medial wall. This article presents a clinical case of an aortopulmonary window with typical clinical symptoms, describes the specifics of its surgical treatment, and discusses the long-term outcomes of therapy. Current literature was reviewed to assess contemporary approaches to the diagnosis and treatment of this cardiac defect. Aim. To present a clinical case of an aortopulmonary window with characteristic symptoms, to demonstrate the peculiarities of surgical correction, and to analyze the long-term treatment outcomes. Materials and Methods. This article presents the clinical case of an eight-year-old boy with an aortopulmonary window, diagnosed from an early age. To accurately determine the location and size of the defect, and to assess valve function, physical examination, electrocardiogram, chest X-ray, echocardiography, and aortography were performed, aligning with the advanced recommendations in the literature. Surgical intervention was performed under cardiopulmonary bypass – a standard method ensuring the safety and successful correction of the defect, as supported by research data. Results and Discussion. The patient with an aortopulmonary window presented with the characteristic complaints of dyspnea and rapid fatigue, consistent with literature data on circulatory disturbances associated with this defect. Physical examination revealed typical signs: A loud second heart sound and a systolic murmur. Diagnosis using echocardiography and angiography allowed for precise determination of the defect’s location and size. Surgical correction under cardiopulmonary bypass was successful, showing positive dynamics in the patient’s clinical condition. The literature review confirms the efficacy and safety of the chosen method; however, continuous postoperative follow-up is necessary for timely detection of complications. Conclusions. Successful diagnosis and surgical correction of the aortopulmonary window significantly improved the patient’s condition. The method is confirmed by literature as effective and safe, with regular postoperative monitoring being essential.</jats:p>
