Abstract:

The aim of the study was to assess the powers of complex ultrasonography in different stages of endovascular closure of atrial septal defects (ASD). 31 patients 13-56 years old (mean age 23,65 ±5,2 years) with septal defects were included into the study. Ultrasound (US) monitoring performed during the procedure of endovascular closure, and as a follow-up. There were prevalence (35,4%) of the patients with central ASD with rims of 5 mm and more. Abcence of anterio-superior or aortic rim, or its deficiency, noted in 19,2% of cases. Patent foramen ovale (PFO) registered in 25,81% of patients. Incidence of multiple ASDs and ASD in aneurysm occurred to be similar and was as high as 9,67%. In 2 cases of multiple ASDs, and 2 cases of PFO, transseptal puncture was used as an approach to left atrium, for the reason of complex anatomy of the septum. After the closure, transthoracic US showed reliable decrease of the right atrium, right ventricle, and pulmonary artery (PA) size. The majority of patients (64%) showed normalization of PA pressure and left ventricle enlargement in a week after the procedure. Two-dimensional echocardiography (EchoCG) with color Doppler mapping (CDM) is the key method for ASD imaging and assessing its suitability for endovascular closure. Transesophageal EchoCG can help in verification of the ASD anatomy and refinement of the ASD rims. Ultrasound guidance during the procedure of endovascular closure allows optimal positioning of the device, immediate assessment of the homodynamic effects, and timely diagnosis of complications.
