Background: Although the use of protocols for "enhanced recovery after surgery" (ERAS) have been associated with improved results in different surgical specialties, only a few data are available for ERAS in cardiac surgery. This study aimed to compare 30-day outcomes of patients undergoing ultra-fast-track minimally invasive valve surgery (UFT-MIVS) versus conventional MIVS (c-MIVS)., Methods: The key features of UFT-MIVS approach involves: 1) less invasive valve surgery techniques, 2) normothermic cardiopulmonary bypass management, 3) UFT-anesthesia with table extubation, 4) immediate rehabilitation therapy and patient-family contact. Five-hundred and seventy-six consecutive patients who underwent aortic or mitral MIVS were analyzed (2016-2020). Treatment selection bias (UFT-MIVS vs. c-MIVS) was addressed by the use of propensity score (PS) matching. After PS-matching 2 well-balanced groups of 152 patients each were created., Results: In the matched cohort, the overall 30-day mortality and stroke rates were 0.3% and 0.7%, respectively, with no difference between groups. UFT-MIVS resulted in lower rates of respiratory insufficiency and agitation/delirium compared with c-MIVS. Patients receiving UFT-MIVS were associated with significantly shorter intensive care unit length of stay and hospital stay., Conclusions: Our study confirms that MIVS is associated with excellent results in terms of early mortality and major postoperative complications rates. The implementation of UFT-MIVS protocol showed to be safe and was associated with improved clinical outcomes in regard to respiratory insufficiency, delirium and lengths of stay., Competing Interests: Declaration of competing interest None to declare., (Copyright © 2022 Elsevier B.V.

Treatment of aortic valve disease has become less and less invasive during the last years, thanks to progress in anesthesiology, surgical techniques, and perfusion management. In fact, it has been demonstrated that shorter skin incision, combined with ultra-fast-track anesthesia and minimized extracorporeal circuit could improve clinical outcomes. Current evidence shows that minimally invasive extracorporeal circulation system is associated with reduced red blood cells' transfusion rate, improved end-organ perfusion, decreased incidence of postoperative atrial fibrillation, air embolism leakage, and so less cerebral accidents with better neurological outcomes. Moreover, the use of a closed circuit seems to be more physiologic for the patients, reducing systemic inflammatory response due to less air-blood contact and the use of biocompatible surfaces. In the literature, the benefits of minimally invasive extracorporeal circulation are described mostly for coronary surgery but few data are nowadays available for minimally invasive extracorporeal circulation during aortic valve replacement. In this article, we describe our perfusion protocol in minimally invasive aortic valve replacement.

Objectives: The impact of minimally invasive extracorporeal circulation (MiECC) systems on the clinical outcomes of patients undergoing minimally invasive aortic valve replacement (MI-AVR) has still to be defined. This study compared in-hospital and 1 year outcomes of MI-AVR interventions using MiECC systems versus conventional extracorporeal circulation (c-ECC)., Methods: Data from 288 consecutive patients undergoing primary isolated MI-AVR using MiECC (n = 102) or c-ECC (n = 186) were prospectively collected. Treatment selection bias was addressed by the use of propensity score matching (MiECC vs c-ECC). After propensity score matching, 2 groups of 93 patients each were created., Results: Compared with c-ECC, MiECC was associated with a higher rate of autologous priming (82.4% vs 0%; P < 0.001) and a greater nadir haemoglobin (9.3 vs 8.7 g/dl; P = 0.021) level and haematocrit (27.9% vs 26.4%; P = 0.023). Patients who had MiECC were more likely to receive ultra-fast-track management (60.8% vs 26.9%; P < 0.001) and less likely to receive blood transfusions (32.7% vs 44%; P = 0.04). The in-hospital mortality rate was 1.1% in the MiECC group and 0% in the c-ECC group (P = 0.5). Those in the MiECC group had reduced rates of bleeding requiring revision (0% vs 5.3%; P = 0.031) and postoperative atrial fibrillation (AF) (30.1% vs 44.1%; P = 0.034). The 1-year survival rate was 96.8% and 97.5% for MiECC and c-ECC patients, respectively (P = 0.4)., Conclusions: MiECC systems were a safe and effective tool in patients who had MI-AVR. Compared with c-ECC, MiECC promotes ultra-fast-track management and provides better clinical outcomes as regards bleeding, blood transfusions and postoperative AF. Thus, by reducing surgical injury and promoting faster recovery, MiECC may further validate MI-AVR interventions., (© The Author(s) 2019.

Background: Over the years, with the introduction of minimally invasive techniques and technologies aimed at reducing surgical trauma, aortic valve surgery has considerably developed and improved. Our approach includes: reduced incisions (upper "J" ministernomy or anterior right minithoracotomy), "ultra fast-track" anesthesia protocols, sutureless and rapid deployment valve prostheses and miniaturized circuits of extracorporeal circulation. The aim of this study was to evaluate the clinical outcomes associated with this multidisciplinary approach., Methods: Between October 2016 and November 2018, 429 patients underwent isolated aortic valve replacement at the Cardiac Surgery Unit of the "Ospedali Riuniti" of Ancona, Italy. Overall, 91 patients (21.2%) were operated according to our minimally invasive approach. A severe aortic valve stenosis was the indication for surgery in 90.1% of patients, aortic valve insufficiency in the remaining 18.7%., Results: There were neither in-hospital deaths nor major or minor neurological events. Atrial fibrillation was the main postoperative complications (n=26, 28.6%). Four patients (4.4%) underwent permanent pacemaker implantation due to third-degree atrioventricular block, and a surgical bleeding revision was performed in 3.3%. No episodes of respiratory failure were reported. The median length of hospital stay was 6 days (5-8 days)., Conclusions: Our initial experience with a 360° minimally invasive approach for the treatment of patients undergoing aortic valve replacement shows encouraging clinical outcomes; this approach may lead to an improved perception of surgery both by patients and their families. However, further clinical studies are needed to evaluate the long-term results.

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.
