There is usually a combination of a single atrioventricular valve and two thick ventricular septa. This defect is most often diagnosed in children, including newborns, and may present with a number of clinical symptoms, such as shortness of breath, cyanosis, chest pain, and growth retardation. The pathology may cause the development of heart failure and other complications that require intensive medical intervention. <\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 counter-flat

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The first mentions of heart defects, including partial atrioventricular canal, can be traced back to ancient texts. Significant advances in the diagnosis and treatment of such diseases became possible only with the development of cardiology as a science in the 19th and 20th centuries. In the 1940s, researchers began actively studying echocardiography, which subsequently allowed for more accurate detection of cardiac anatomy anomalies, including atrioventricular septal insufficiency. In the 1970s, the advent of modern surgical techniques began a new era in the treatment of PAVC, allowing patients to live a full life. Interestingly, the development of heart transplantation in the late 20th century also contributed to the understanding of the mechanics and general pathophysiology of defects such as PAVC, including through the exchange of surgical experiences between specialists.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to various epidemiological data, the incidence of partial atrioventricular canal is approximately 4\u20138% of all congenital heart defects. Depending on the population, this figure may vary, with the prevalence in neonates reaching approximately 1 in 1,500\u20132,500 live births. Partial atrioventricular canal is more common in women than in men, with a ratio of approximately 3:1. The disease may also be associated with other cardiac anomalies, such as Down syndrome and other chromosomal abnormalities, increasing the risk of developing PAVK in these patient groups.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%BC%D1%83_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E\"><\/span>Genetic predisposition to this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Partial atrioventricular canal may have a genetic origin, especially if there are cases of such a disease in the family or among close relatives. Studies have shown that mutations in genes such as GATA4, NKX2-5 and TBX5 may play a significant role in the pathogenesis of congenital heart defects, including PAC. These genes are responsible for the regulation of cardiac embryology and are often involved in the mechanisms of cell migration and differentiation during the formation of the cardiovascular system. In addition, chromosomal abnormalities such as trisomy 21 (Down syndrome) have also demonstrated a close association with the development of this defect.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Risk factors for the development of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are several risk factors that may contribute to the development of partial atrioventricular canal:<\/p>\n<ul>\n<li>Hereditary predisposition to cardiovascular abnormalities.<\/li>\n<li>Chromosomal abnormalities (eg, Down syndrome).<\/li>\n<li>Maternal exposure to toxic or chemical substances during pregnancy, including alcoholism or drug addiction.<\/li>\n<li>Maternal infectious diseases, such as rubella or influenza, during the first trimesters of pregnancy.<\/li>\n<li>Maternal metabolic diseases such as diabetes.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%94%D0%B8%D0%B0%D0%B3%D0%BD%D0%BE%D1%81%D1%82%D0%B8%D0%BA%D0%B0_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Diagnosis of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Diagnosis of partial atrioventricular canal requires a comprehensive examination and may include:<\/p>\n<ul>\n<li>Main symptoms: shortness of breath, cyanosis, difficulty breathing, fatigue, underdevelopment in childhood.<\/li>\n<li>Laboratory tests: arterial blood oxygenation level analysis, complete blood count and biochemistry.<\/li>\n<li>Radiological examinations: chest X-ray to assess the size of the heart and pulmonary vessels.<\/li>\n<li>Echocardiography: is the main imaging method that allows us to see abnormalities in the structure of the heart and evaluate its function.<\/li>\n<li>CT or MRI of the heart: may be used for more detailed analysis of specific abnormalities.<\/li>\n<li>Differential diagnosis: includes exclusion of other forms of heart defects such as a full atrioventricular canal and other anomalies.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%9B%D0%B5%D1%87%D0%B5%D0%BD%D0%B8%D0%B5\"><\/span>Treatment<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Treatment for partial atrioventricular canal may be multi-step, including:<\/p>\n<ul>\n<li>General treatment: supportive care, including physical rehabilitation and regular monitoring of cardiac status.<\/li>\n<li>Pharmacological treatment: may include diuretics, ACE inhibitors to control heart failure.<\/li>\n<li>Surgical treatment: Atrioventricular canal repair may require surgery to create a normal valve orifice and correct septal insufficiency.<\/li>\n<li>Other treatments: In some cases, implantation of a pacemaker or use of techniques to improve blood circulation may be necessary.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A1%D0%BF%D0%B8%D1%81%D0%BE%D0%BA_%D0%BB%D0%B5%D0%BA%D0%B0%D1%80%D1%81%D1%82%D0%B2_%D0%BF%D1%80%D0%B8%D0%BC%D0%B5%D0%BD%D1%8F%D0%B5%D0%BC%D1%8B%D1%85_%D0%B4%D0%BB%D1%8F_%D0%BB%D0%B5%D1%87%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>List of medications used to treat this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The main groups of drugs used for partial atrioventricular canal regurgitation include:<\/p>\n<ul>\n<li>Diuretics (eg, furosemide) -
