[THE RESULTS OF ENDOVASCULAR CLOSURE OF A SECONDARY DEFECT OF INTERATRIAL SEPTUM].

Efficacy and security of transcutaneous closure for secondary defect of interatrial septum (DIAS) in 299 patients, using occluders, were studied. Cardiac dysrythmia was the most frequent complication--in 10 (3.3%) patients, the apparatus shift was noted in 4 (1.3%), in 1 (0.3%)--the air embolism of right parts of the heart have occurred. In 289 (98.2%) patients normalization of right parts of heart was achieved. In 84.4% of patients the absence of a residual shunt immediately after the procedure was observed, before the check-out from the hospital--in 89.2%, and in 6 mo--in 97.7%. Transcutaneous closure of secondary DIAS constitutes a secure, effective and less traumatic method, than surgical treatment. Today endovascular method is considered a "gold standard" in treatment of this heart failure. Keywords: secondary defect of interatrial septum; transcutaneous closure; occluder.
