Abstract

The volume of the left atrium is one of the key factors associated with both the development of primary atrial fibrillation and its progression. Open atrial communication is considered as a factor predisposing to dilation and remodeling of the heart cavities. We present a clinical case of endovascular closure of an open oval window in a patient with a persistent form of AF, a moderately reduced left ventricular ejection fraction, who had previously undergone radiofrequency ablation, and persistent manifestations of heart failure. A 58-year-old patient was hospitalized in November 2019 with clinical manifestations of increasing heart failure. History: persistent form of atrial fibrillation with pronounced ventricular tachysystole. In April 2019, the patient underwent radiofrequency ablation, during which signs of open oval window were revealed. The initial left ventricular ejection fraction is 41%, the anterior–posterior left atrium size is 47 mm, the NT-proBNP level is 912 pg/m. In the subsequent period, steady sine waves were recorded.
