Yu.V. Zinchenko, M.R. Ikorkin Role of transesophageal echocardiography in performing cardioversion in patients with atrial flutter

We performed 89 transesophageal electric cardiac stimulation procedures in order to restore sinus rhythm in 75 (84,3%) men and 14 (15,7%) women with atrial flutter type I due to coronary heart disease (59 (66,3%)) and
myocardiofibrosis (30 (33,7%)). All patients underwent transthoracic and transesophageal echocardiography. All patients were divided into two groups: in group I (n=39) mean left atrium appendage ejection velocity was ≤ 40 cm/s, in group 2 (n=50) – above 40 cm/s. According to our study results, patients in group I had significantly longer atrial flutter episode duration, more often concomitant hypertension and atrial fibrillation, with less effective cardioversion with frequent relapses and transformation into constant form. In the patients of group 2 no spontaneous contrast phenomenon grade II–IV and intra­atrial hemodynamics of type II–III was observed, while at transesophageal electric cardiac stimulation restoration of sinus rhythm without fibrillation episode was observed, suggesting possibility of decreased duration of anticoagulant therapy before the procedure.
