Abstract:

Despite the fact that so far in the literature, many cases of endovascular closure of paravalvular leak (PVL), this type of intervention is unusual and is associated with a complex technical issues. In addition, the majority of publications devoted to the correction of mitral and aortic PVL, while the description of the closing of the tricuspid valve (TV) PVL are rare.

Below is a description of our first experience of endovascular correction of TV PVL in 54 years ole patient, who underwent TV repair with «Neokor-32» - supporting ring as a correction of atrial septal defect, TV insufficiency One year after surgery the patient reported a decrease in physical activity tolerance. Echocardiography diagnosed hemodynamically significant PVL of TV, 6mm size with leakage between the left ventricle and the right atrium and formation of pulmonary hypertension. PVL was successfully treated by endovascular correction with using of device for closure of ventricular septal defect.

Abstract:

Endovascular correction of atrial septal defect (ASD) has become the «gold standard» of treatment, both in children and adults. In case of complicated anatomy of the defect (multiple defects, its large size, lack of edges, aneurysm of atrial septum), experts often chose surgical correction of such pathology Accumulated experience of interventional cardiology and appearance of specialized tools allow to perform a successful intervention in a non-standart situation.

Article describes cases of a successful endovascular correction of ASD in a two year child and adult patient with complicated anatomy factors. In both cases, during echocardiography, we diagnosed multiple ASD with aneurysm of atrial septum, accompanied by clinical symptoms. During multidisciplinary discussions, we identified indication for endovascular correction of the defect.

We performed successfull correction of ASD with occluder for closure of patent foramen ovale, and complete termination of left-to-right shunt on the operating table.
