Robotic assisted aortic valve surgery is still challenging and debatable. We retrospectively reviewed our cases of robotic assisted aortic valve replacement utilizing sutureless aortic valve with following surgical technique: 3 ports, 1 for endoscope and 2 for the robotic arms were inserted in the right chest and da Vinci Si robotic system (Intuitive Surgical, Sunnyvale, CA, USA) was adapted to these ports. Cardiopulmonary bypass was initiated through peripheral cannulations. A vent cannula was placed through the right superior pulmonary vein and a cardioplegia cannula in the ascending aorta. After cardioplegic arrest following aortic cross-clamp, the aortic valve was exposed through a clam shell aortotomy. Valvectomy along with decalcification was performed. Next using 3 guiding sutures the Perceval S valve (LivaNova, London, UK) was parachuted down and deployed. After confirming valve position, the aortotomy was closed. There were no major complications during the procedures and no conversion to sternotomy. Exposure of aortic valve was of high quality. Valvectomy required assistance with long scissors by the bedside surgeon for excision of the severely calcified valve cusps and effective decalcification of annulus. Postoperative convalescence was uncomplicated except for postoperative atrial fibrillation in 1 patient. Robotic assistance in aortic valve procedure enabled excellent exposure of the aortic valve and improved manipulation and suturing of the aortic annulus and aorta. There needs to be improvement of instrumentation for valve debridement and removal of calcium from the annulus. In addition, the sutureless valve technology contributes to the feasibility and the efficacy of this procedure.

Sutureless aortic valve replacement (AVR) is a wide-spreading new technology that provides short clamping time and excellent hemodynamic outcomes. However, among its possible complications is the risk of paravalvular leak. We present the case of a 63-year-old woman who underwent minimally invasive right mini-thoracotomy AVR) with Perceval S sutureless valve (LivaNova, London, UK). Intraoperative transesophageal echocardiography revealed severe paravalvular leak with stent distortion. Rescue balloon valvuloplasty was performed through the right femoral artery, and resulted in the resolution of the paravalvular leak. This case illustrates the utility and feasibility of balloon valvuloplasty in trouble-shooting sutureless aortic valve stent distortion, thus avoiding a repeat aortic cross-clamp and valve replacement.

Reoperations for a dysfunctional mechanical aortic valve prosthesis are usually performed with a repeat sternotomy. Reopening the chest may be associated with a heart structure tear, bleeding, excessive transfusion, and a possible unfavorable outcome. Experience performing a redo aortic valve replacement with a minimally invasive approach and avoiding lysis of the pericardial adhesions is growing. We describe a redo aortic valve replacement procedure performed because of subvalvular pannus formation in a patient with a mechanical prosthesis. A partial J-shaped hemisternotomy at the 3rd intercostal space was performed; the ascending aorta was exposed and the valve was replaced with a sutureless bioprosthesis. The video tutorial shows the surgical approach, cardiopulmonary bypass solutions, and sutureless valve deployment.

Abstract OBJECTIVES Totally endoscopic aortic valve replacement (AVR) is still a challenging operation, and only a few series reports exist in the literature. The purposes of this study were to establish a method for endoscopic AVR and evaluate its initial results. METHODS A total of 47 patients (median age 76 years, 17 men) underwent endoscopic AVR. The main wound was created in the right anterolateral 4th intercostal space through a 4-cm skin incision. No rib spreader was used. A 3-dimensional endoscope was inserted at the midaxillary line. A 5.5-mm trocar was inserted in the 3rd intercostal space, thus creating a 3-port setting similar to that used for endoscopic mitral valve surgery. A standard prosthesis was used, and the sutures were tied using a knot pusher. Results were compared with those of 157 patients who underwent right transaxillary AVR with direct vision plus endoscopic assist. RESULTS Patient backgrounds did not differ significantly between the 2 groups. No deaths occurred in the entire series. There was no conversion to thoracotomy or sternotomy in the endoscopic AVR group. The complication rate did not differ significantly between the 2 groups. The total operating time was significantly shorter in endoscopic AVR (188–206 min); the cardiopulmonary bypass time (130–128 min) and the cross-clamp time (90–95 min) did not differ significantly (median, endoscopic AVR, right transaxillary AVR). Two patients underwent endoscopic double-valve (aortic and mitral) surgery under the same conditions. CONCLUSIONS Endoscopic AVR was possible through 3 ports created in the right anterolateral chest, similar to the procedure for endoscopic mitral valve surgery. By adopting a common approach for both the aortic and the mitral valve operations, endoscopic double-valve surgery can be performed seamlessly.

Objective For elderly patients with symptomatic aortic valve stenosis, aortic valve replacement with tissue valves is still the treatment of choice. Stentless valves were introduced to clinical practice for better hemodynamic features as compared with stented tissue valves. However, the implantation is more complex and time demanding, especially in minimal invasive aortic valve replacement. We present our clinical data on 22 patients having received a sutureless ATS 3f Enable aortic bioprosthesis via partial upper sternotomy. Methods The procedure was performed using CPB with cardioplegic arrest. After resection of the stenotic aortic valve and debridement of the annulus, the valve was inserted and released. Mean age was 79 years, and mean logistic Euroscore was 13. Subvalvular myectomy was performed in two patients. Prosthetic valve sizes were 19 mm (n = 1), 21 mm (n = 7), 23 mm (n = 6), 25 mm (n = 6), and 27 mm (n = 2). Results Implantation of the valve required 10 ± 6 minutes. Cardiopulmonary bypass and aortic crossclamp time were 87 ± 16 and 55 ± 11 minutes, respectively. Early mortality (<90 days) was 9% (2 patients). No paravalvular leakage was detected intraoperatively or in follow-up echocardiography. The mean transvalvular gradients were 9 ± 6 mm Hg at discharge and 8 ± 2 mm Hg at 1-year follow-up. Conclusions Sutureless valve implantation via partial sternotomy is feasible and safe with the ATS 3f Enable bioprosthesis. Reduction of cardiopulmonary bypass and aortic crossclamp time seems possible with increasing experience. Hemodynamic data are very promising with low gradients at discharge and after 12 month. Sutureless valve implantation via minimal invasive access may be an alternative treatment option for elderly patients with high comorbidity.

Aortic valve replacement (AVR) in patients with a small aortic annulus is a challenging issue. The importance of prosthesis–patient mismatch (PPM) post aortic valve replacement (AVR) is controversial but has to be avoided. Many studies support the fact that PPM has a negative impact on short and long term survival. In order to avoid PPM, aortic root enlargement may be performed. Alternatively and keeping in mind that often some comorbidities are present in old patients with small aortic root, the Perceval S suturelles valve implantation could be a perfect solution. The Perceval sutureless bioprosthesis provides reasonable hemodynamic performance avoiding the PPM and providing the maximum of aortic orifice area. We would like to see in the near future the role of the aortic root enlargement techniques in the era of surgical implantation of the sutureless valve (SAVR) and the transcatheter valve implantation (TAVI).

Objective: The objective of this prospective study was to evaluate the characteristics (positive and negative) of Perceval S valve in patients undergoing aortic valve replacement with a biological prosthesis. The study included 67 patients operated on at our institution and a mean follow-up period of 18 months. Methods: From June 2016 to November 2019, 209 patients underwent aortic valve replacement with a biological prosthesis. Of these, 67 patients were included in the study based on the exclusion and inclusion criteria set before the study began. Their data were recorded during their hospital stay (preoperative, intraoperative, and early and late postoperative time). Results: Fifty-four patients underwent isolated aortic valve replacement (group I) with a Perceval S prosthesis, and 13 patients had combined aortic valve replacement procedures and CABG procedures (group II). Patients were implanted with the following prosthesis sizes: S (N = 12), M (N = 18), L (N = 28), or XL (N = 9). The Perceval S valve successfully was implanted in 67 (91.8%) patients (in 6 patients, the preoperative transthoracic echocardiographic data did not coincide with intraoperative TEE and surgical measurement of the size of the annulus in the suture). Surgical approaches in patients were medial sternotomy (N = 48), mini sternotomy (N = 15), and thoracotomy through the second intercostal space to the right (N = 4). The mean clamping time of the aorta and CPB length for isolated cases was 54 and 82 minutes, respectively, and 96 and 120 minutes for combined procedures. Four (5.9%) patients died within 30 days. Conclusion: Early postoperative results showed that the Perceval S valve was safe. Further follow up is required to evaluate the long-term duration of patients with this bioprosthesis.
