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.

Introduction: The assessment of post-procedual aortic regurgitation (PAR) after transcatheter aortic valve replacement (TAVR) has not been validated. The purpose of this study was (1) to investigate the value of holodiastolic flow reversal (HDFR) in the descending aorta in patients with PAR after TAVR and (2) to determine which color Doppler parameters are useful for PAR grading using the intraprocedural transesophageal echocardiography (iTEE). Hypothesis: We hypothesized that HDFR in the descending aorta and any color Doppler parameters can delineate significant PAR after TAVR. Methods: Three hundred-eighty patients with severe aortic stenosis underwent TAVR with the Edwards SAPIEN valve with 131 pulsed-wave Doppler tracings from the descending aorta had assessed by iTEE. PAR was evaluated using 2D color Doppler by the cross-sectional area of the vena contracta (VCA) at the aortic annular plane, and by the longitudinal jet extent (mosaic signals, Figure A) compared to the location of the tip of the anterior mitral leaflet (AML). Significant PAR was defined as VCA of ≥10 mm2, corresponding to greater than a moderate grade. Results: In patients with any grade of PAR, pulsed-wave Doppler tracing from the descending aorta, jet extent and VCA were obtained in 100%, 80%, and 74%, respectively. All patients with consistent HDFR had significant PAR. By multivariate analysis, a consistent HDFR and jet extent beyond the tip of AML were independent predictors of significant PAR. A consistent HDFR and jet extent beyond the tip of AML predicted significant PAR with specificity of 100% and 97%, respectively. In the other hand, patients with both negative HDFR and jet extent of less than halfway to the tip of AML had no significant PAR with a 97% specificity. Conclusions: The presence of HDFR with each cardiac cycle and jet extent beyond the tip of AML are indicative of significant PAR.

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.

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.
