Ultra fast-track minimally invasive aortic valve replacement: going beyond reduced incisions

Aortic valve replacement (AVR) via a median sternotomy approach has been largely reported to be safe and long-term efficacious, and currently represents the 'gold standard' approach for aortic stenosis treatment. However, aortic valve surgery has undergone continuous development over the last years, involving less invasive techniques and new technologies to reduce the traumatic impact of the intervention and extend the operability toward increasingly high-risk patients. Indeed, minimally invasive AVR and transcatheter aortic valve replacement caseload have steadily increased leading to a paradigm shift in the treatment of aortic valve disease. In this setting, we have established a multidisciplinary minimally invasive programme to treat patients who require AVR. Herein, we present our approach including (i) reduced chest incision (through a J ministernotomy), aiming to reduce the traumatic impact of the surgical procedure, to decrease blood loss, postoperative pain and wound complications and to increase patient's satisfaction; (ii) rapid-deployment AVR, to reduce operative times, to facilitate minimally invasive approach and to improve haemodynamic outcomes; (iii) minimal invasive extracorporeal circulation system, to improve end-organ protection, to decrease systemic inflammatory response and to promote fast-track anaesthesia and (iv) ultra fast-track anaesthesia, to decrease the rate of postoperative complications and assure better and earlier recovery

Results and insights after 413 TAVI procedures performed by cardiac surgeons on their own

OBJECTIVES: Current evidence on transcatheter aortic valve implantation (TAVI) has been generated exclusively by cardiology studies and no operative data from cardiac surgeons are available. Here, we describe the development of our TAVI programme and report the results of transfemoral (TF) TAVI done by cardiac surgeons on their own.METHODS: This study included all the TAVI procedures on native valve performed at Cardiac Surgery Unit, Ospedali Riuniti di Ancona, during the period October 2018 to July 2022. Relevant prospectively collected preoperative, intraprocedural and postoperative data were retrieved from the Institutional database.RESULTS: A total of 413 patients were included in the study. Mean patients' age was 82 years and among them 44% (180/413) were male. STS score was 3.1% (2.2-4.4). Eighty patients underwent transapical TAVI and 333 patients had a TF approach. We progressively moved from transapical TAVI towards TF procedures that are now routinely performed on conscious sedation and using a fully percutaneous approach. After TF TAVI, 30-day mortality rate was 1%, cerebral stroke occurred in 2% of the cases, permanent pacemaker implantation was necessary in 23% of the patients and in 6% of the cases there was a moderate/severe degree of aortic regurgitation. There was no association between operators performing TAVI and 30-day mortality.CONCLUSIONS: The acquisition of catheter-based skills and an adequate training allowed cardiac surgeons to perform on their own awake and fully percutaneous TF TAVI with similar results when compared with major randomized clinical trials and registries' experiences

Improved Early Outcomes in Women Undergoing Aortic Valve Interventions

Surgical aortic valve replacement (SAVR) in female patients has been associated with higher mortality (up to 3.3-8.9%) and postoperative complication rates when compared with their male counterparts. In recent years, TAVI has been shown to provide a greater benefit than SAVR in women. We sought to assess the early outcomes of the contemporary aortic valve intervention practice (surgical and transcatheter) in patients referred to our cardiac surgery unit. The data of consecutive patients who underwent isolated aortic valve intervention for aortic valve stenosis during the 2018-2022 period were retrieved from our internal database. Several preoperative, intraoperative, and postoperative variables were analyzed, including the predicted risk of a prosthesis-patient mismatch. Nine hundred and fifty-five consecutive patients-514 women and 441 men-were included. Among them, 480 patients-276 female and 204 male-received a transcatheter procedure, and 475-238 women and 237 men-had conventional SAVR. The women were older and had higher EuroSCORE II, while the male patients presented a higher incidence of cardiovascular comorbidities. There was no difference in mortality or major postoperative complication rates after either the surgical or transcatheter procedures between the female and male populations. The availability and targeted use of different techniques and technologies have enabled the safe and effective treatment of female patients treated for severe symptomatic aortic valve stenosis with similar results when compared with their male counterparts

[Early and mid-term results of the transapical aortic valve Symetis Acurate TA: a viable solution in high-risk patients with severe vascular disease]

Aortic valve stenosis is the most common valvular disease in the elderly. Transcatheter aortic valve implantation represents a viable alternative to conventional aortic valve replacement. In our Department, the transapical approach is the preferred method in patients with severe peripheral vascular disease. The aim of this study was to analyze the early and midterm results of Symetis Acurate TA implantation in our series
