Objective. To research of possibilities of reconstruction of aorta`s ostium and ascending aorta during aortic valve replacement and simultaneous correction of mitral valve defects at patients with narrow aorta`s ostium. Materials and methods. The study group consisted of 46 patients with mitral-aortic heart diseases and combination with a narrow aortic mouth, who were operated on at the A Amosov National Institute of Cardiovascular surgery for the period from January 1, 2006 to January 1, 2020. All patients underwent reconstruction of the aortic root and ascending aorta according to the original method of posterior aortoplasty. There were 26 men (56.5%) and 20 women (43.5%). The age of patients ranged from 23 to 72 years (average - 58.4±7.3 years). 8 (17.4%) patients belonged to class III NYHA, 38 (82.6%) - to class IV. Results. Of the 46 operated patients at the hospital stage (30 days after surgery), 4 died (hospital mortality 8.7%). No fatalities were associated with surgical technique. The dynamics of echocardiographic parameters at the hospital stage was as follows: the systolic gradient on the aortic valve was before surgery 112.1 ± 15.2 mm Hg, on the aortic prosthesis at discharge - 23.2 ± 6.4 mm Hg; end-systolic index (ESI) of the left ventricle (ml/m²) - 59.1 ± 7.6 (before surgery) and 48.3 ± 5.9 (after surgery); left ventricle ejection fraction (EF) - 0.45 ± 0.04 (before surgery) and 0.53 ± 0.04 (after surgery). Conclusions. The proposed original technique of posterior aortoplasty allows to effectively expand the mouth of the aorta for further implantation of an artificial heart valve of larger diameter. The technique is quite safe. At the hospital stage there are no complications directly related to the technique of operations. At the early postoperative period, the morphometric parameters of the left ventricle (EF and ESI) improved. The technique can be successfully used for the correction of combined mitral-aortic valve defects.

132 patients with isolated aortic valve disease with narrow aortic ostium who underwent surgery in the Institute from 1 May 2009 to 01 Jan 2019 are included in the study group. Among 132 patients, 6 died at the hospital stage (hospital mortality – 4.5%). There were no negative remarks to the surgical technique in any case. Changes in echo data during the hospital stay: systolic pressure gradient across the left ventricular outflow tract (LVOT) before operation was 105.1±11.5 mmHg, with 25.9±4.1 mmHg on the aortic prosthesis upon discharge. Reconstruction of the root and ascending aorta according to the proposed method in cases of aortic hypoplasia and aortic valve replacement (AVR) is highly effective intervention. The purpose of this research is to study possibilities of a new approach to the reconstruction of the root and ascending aorta in AVR.

Objective An accepted landmark to assess feasibility of surgical aortic valve replacement (SAVR) via right anterolateral minithoracotomy (RALT) is the aortic-midpoint to right-sternal-edge distance. We aimed to evaluate single left lung positive-end-expiratory-pressure (SLL-PEEP) ventilation inducing an intraoperative rightward shift of the ascending aorta to improve exposure. Methods Nineteen patients with aortic stenosis undergoing SAVR via RALT were prospectively analyzed. SLL-PEEP ventilation (20,395 cmH2O) via a double-lumen endotracheal tube was applied immediately before transthoracic aortic cross-clamping, thereby inducing rightward shift of the ascending aorta to enhance exposure. We analyzed preoperative computed tomography (CT) reconstructions and intraoperative video recordings. Primary endpoint was extent of rightward shift induced by SLL-PEEP ventilation; secondary endpoints were procedure times and safety events. Results Mean age was 61 ± 14.8 years and 6 of 19 (31.6%) were female. Mean EuroSCORE II was 0.81% ± 0.04%, STS-PROM was 1.13% ± 0.74%, and mean aortic rightward shift induced by SLL-PEEP ventilation was 10.32 ± 4.14 mm (4 to 17 mm; P = 0.003). Median shift in the group considered suitable for the RALT approach by preoperative CT-scan evaluation was 14.2 mm (IQR 11) and in the less suitable group 11.5 mm (IQR 5). Mean procedure time was 167 ± 28.9 min, CPB time was 105.7 ± 18.4 min, and cross-clamp time was 64.5 ± 13 min. Fifteen patients (79%) received SAVR via RALT with implantation of a bioprosthesis, whereas a rapid-deployment-prosthesis was used in 4 patients (21%). Ten of 19 (53%) patients who were classified as less suitable preoperatively received SAVR via RALT after SLL-PEEP ventilation. No strokes were observed. Conclusions The SLL-PEEP ventilation maneuver during SAVR via RALT significantly enhances aortic exposure. There were no safety events associated with this maneuver and we were able to demonstrate significant rightward aortic shift in every single patient.

Abstract An 84-year-old patient was referred for severe symptomatic aortic valve stenosis and focal chronic dissection of the ascending aorta. After multidisciplinary discussion, the patient was scheduled for combined transapical transcatheter aortic valve replacement and ascending aorta stent-grafting. The procedure was performed with a balloon aortic valvuloplasty followed by a custom-made stent graft implantation into the ascending aorta and then by balloon-expandable transapical transcatheter aortic valve replacement. The patient had an uneventful hospital stay. In conclusion, in selected high-risk patients, transapical combined ascending aorta stent-grafting and transcatheter aortic valve replacement are feasible and safe.

Background: Several risk factors, including emergency surgery, predicted early mortality after aortic valve replacement (AVR).  Euroscore II is used to predict the mortality after cardiac operations. We aimed to review our experience in AVR and determine the early mortality predictors Methods: We collected the data of 200 rheumatic patients who had standard AVR in two centers. Median sternotomy and cardiopulmonary bypass were used in all patients. Transcatheter and minimally invasive aortic valve replacement patients were excluded. We used 15 types of aortic valve prostheses, either mechanical or biological. Follow-up echocardiography was done in the intensive care unit, on discharge, and one month after discharge.     Results: 128 patients (64%) had mechanical AVR, and 130 patients (65%) were males. The mean age was 48.2 ± 19 years, and body mass index was 1.8 ± 0.2 Kg/m2. The mean preoperative ejection fraction was 54 ± 9.4 %, end-diastolic dimension was 5.3 ± 0.8 cm, and end-systolic dimension was 3.5 ± 0.9 cm. Nine patients (4.5%) died in the early postoperative period (6 months). Euroscore II was the only factor significantly associated with early mortality (P value= 0.031).  The mean Euroscore II was 1.3 ± 0.9 and 10.1 ± 10.7 for survivors and non-survivors, respectively.  Conclusion: Euroscore II score was significantly associated with early mortality after aortic valve replacement in rheumatic patients and can be used for risk stratification in those patients.

The OBJECTIVE was to demonstrate clinical outcomes of minimally invasive aortic valve replacement (MIAVR).MATERIAL AND METHODS. We retrospectively analyzed surgical results of treatment of patients underwent isolated AVR in our Institution between 2006 and 2018. Overall number of operations was 122; 56 of patient were operated via upper ministernotomy approach. Preoperative characteristics were similar in both groups.RESULTS. In our series MIAVR procedures had prolonged CPB and aortic cross clamping time, what significantly contributed to the increase in manifestations of heart failure in the early postoperative period, but didn’t affect the perioperative mortality and major morbidity rates. MIAVR led to reduction in postoperative blood loss and perioperative red blood cell transfusion rate. Most severe complications occurred in frail patients older than 75 years, and in those with extensive aortic annular calcification.CONCLUSION. MIAVR was the safe and reproducible surgical intervention and rarely led to significant complications in low-risk patients. Prolonged CPB time adversely affected the frequency of significant complications, especially in elderly patients. Although, selected high risk patients might benefit with MIAVR.
