Aim. To study the incidence and possible risk factors for atrial fibrillation (AF) in the early postoperative period after transapical implantation of the first Russian aortic valve (TAP-AVI).Methods. The study included 118 patients after successful TAP-AVI. Patients with open aortic valve replacement due to dislocation of the prosthesis were excluded, as well as subjects with permanent AF and who died in the early postoperative period. The mean age of the patients was 71.1±4.9 years, body mass index 31.1±5.9 kg/m2 , males - 39.8%, hypertension was present in 93.2%, diabetes mellitus (DM) - in 27.9%, paroxysmal AF - in 12.7%, coronary artery disease (CAD) was in 56.7%, 8.4% were smokers. The median follow-up time corresponded to the hospital stay - 9.5 days. To identify cardiac arrhythmias, regular daily ECG recording in 12 leads was initiated from the first day after TAP-AVI. In the presence of palpitations, 24-hour ECG monitoring was performed. Indicators such as age, male gender, DM, history of AF, interatrial block before surgery, CAD, and echocardiographic parameters were studied as possible predictors of AF development in the early postoperative period after TAP-AVI. There were no significant differences in the baseline parameters in patients with AF paroxysms and sinus rhythm.Results. In the early postoperative period, AF was encountered in 46 (39%) of patients. New-onset AF occurred in 38 (32.2%) patients. No cerebrovascular event occurred in patients with post-surgery AF. The only statistically significant risk factor for AF in the postoperative period was CAD (OR 5.756; 95% CI 1.009-8.132; p = 0.048).Conclusion. In the early postoperative period, the only significant predictor of AF was the presence of documented CAD.

Aim. To demonstrate the TAVISCORE program designed to stratify the risk of complications after aortic valve (AV) interventions in patients with reduced ejection fraction.Material and methods. For the period from 2015-2022 at the Almazov Federal North-West Medical Research Center, 128 interventions on AV were performed for aortic stenosis in patients with reduced ejection fraction as follows: 61 — surgical AV replacement (SAVR), 67 — transcatheter aortic valve implantation (TAVI). To create an interactive calculator TAVISCORE (link for free download: https://drive.google.com/file/d/1a3s2MK6Tpk0cIQ_aMB7xe63upEwJsJOh/view?usp=sharing) all patients were combined into one group. For each factor present in the patient, the prognostic coefficient, its contribution to the likelihood of an event in the long-term follow-up period (death, myocardial infarction, stroke), was calculated. The next step, based on the calculations obtained and using the Python 3.10.6 language, was the creation of the TAVISCORE program.Results. The TAVISCORE was created for the personalized choice of tactics for the treatment of patients with aortic stenosis. It contains 54 risk factors and makes it possible to determine probability of cardiac or non-cardiac events in the long-term follow-up period after SAVR and TAVI. Thus, a tactic with lower probability of a complication can be chosen as optimal in this particular case. Retrospective use of the TAVISCORE after surgery can identify patients at high risk of complications, which will allow them to be selected for more thorough management and more frequent screening.Conclusion. The TAVISCORE can be used by a multidisciplinary consensus to select the treatment tactics and stratify the risk of complications after different AV replacement variants in patients with a reduced ejection fraction. Further prospective testing of this program is required.
