Abstract
AIMS Minimally invasive mitral valve surgery leads to shorter postoperative recovery time, cosmetic advantages and significant pain reduction compared with the standard sternotomy approach. Both an external aortic clamp and an endoaortic balloon occlusion can be used to manage the ascending aorta and the myocardial protection. In this study, we aimed to compare these two strategies in terms of effectiveness of myocardial protection and associated early postoperative outcomes. METHODS We investigated the retrospective records of prospectively collected data of patients treated by minimally invasive mitral valve surgery from March 2014 to June 2019. A total of 180 cases (78 in the external aortic clamp group and 102 in the endoaortic balloon clamp group) were collected. A propensity weighting analysis was adopted to adjust for baseline variables. RESULTS The endoaortic balloon clamp presented higher EuroSCORE II (higher reoperative surgery rate). The intra- and postoperative data were similar between the two groups: the postoperative troponin-I levels, peak of serum lactates and rate of myocardial infarction were also comparable. The endoaortic clamp group recorded longer operative, cardiopulmonary bypass and cross-clamp times. The external clamp group showed a higher rate of postoperative atrial fibrillation and conduction block. CONCLUSIONS In experienced centers, the use of the endoaortic balloon clamp is safe, reproducible and comparable to the external aortic clamp regarding the effectiveness of myocardial protection: its employment might facilitate minimally invasive mitral valve surgery.

Abstract
OBJECTIVE Since there are concerns about the durability of mitral valve repair (MVRp) with minimally invasive techniques in patients with mitral regurgitation (MR), we aimed to evaluate the long-term outcomes of these sternal-sparing approaches when compared with conventional approaches with sternotomy in patients undergoing MVRp. METHODS We performed a systematic review according to a preestablished protocol and performed a pooled analysis of Kaplan-Meier-derived reconstructed time-to-event data from studies with longer follow-up comparing sternal-sparing versus sternotomy approaches for MVRp. Our outcomes of interest were survival, freedom from recurrent MR, and freedom from reoperation. RESULTS Eleven studies met our eligibility criteria comprising 7,596 patients with follow-up (sternal sparing, n = 4,246; sternotomy, n = 3,350). Patients who underwent sternal-sparing MVRp had a significantly lower risk of mortality over time compared with patients who underwent MVRp with sternotomy (hazard ratio [HR] = 0.29, 95% confidence interval [CI]: 0.23 to 0.36, P < 0.001) in the overall analysis. However, we found no statistically significant difference between the groups in the sensitivity analysis with adjusted populations (HR = 0.85, 95% CI: 0.63 to 1.15, P = 0.301). Regarding the outcomes freedom from recurrent MR and freedom from reoperation, we found no statistically significant differences between the groups in the follow-up in both overall and sensitivity analyses. CONCLUSIONS In comparison with MVRp with sternotomy approaches, sternal-sparing MVRp was not associated with worse outcomes in terms of survival, recurrent MR, and reoperations over time.

At the Crossroads of Minimally Invasive Mitral Valve Surgery—Benching Single Hospital Experience to a National Registry: A Plea for Risk Management Technology.

Abstract
Almost 30 years after the first endoscopic mitral valve repair, Minimally Invasive Mitral Valve Surgery (MIMVS) has become the standard at many institutions due to optimal clinical results and fast recovery. The question that arises is can already good results be further improved by an Institutional Risk Management Performance (IRMP) system in decreasing risks in minimally invasive mitral valve surgery (MIMVS)? As of yet, there are no reports on IRMP and learning systems in the literature. (2) Methods: We described and appraised our five-year single institutional experience with MIMVS in isolated valve surgery included in the Netherlands Heart Registry (NHR) and investigated root causes of high-impact complications. (3) Results: The 120-day and 12-month mortality were 1.1% and 1.9%, respectively, compared to the average of 4.3% and 5.3% reported in the NHR. The regurgitation rate was 1.4% compared to 5.2% nationwide. The few high-impact complications appeared not to be preventable. (4) Discussion: In MIMVS, freedom from major and minor complications is a strong indicator of an effective IRMP but remains concealed from physicians and patients, despite its relevance to shared decision making. Innovation adds to the complexity of MIMVS and challenges surgical competence. An IRMP system may detect and control new risks earlier. (5) Conclusion: An IRMP system contributes to an effective reduction of risks, pain and discomfort; provides relevant input for shared decision making; and warrants the safe introduction of new technology. Crossroads conclusions: investment in machine learning and AI for an effective IRMP system is recommended and the roles for commanding and operating surgeons should be considered.

Abstract
There is considerable interest and demand in the application of minimally invasive techniques in cardiac surgery driven by multiple factors including patient cosmesis and satisfaction, reduction of surgical trauma and the development of specialized instrumentation that allows these procedures to be performed safely. Minimally invasive mitral valve surgery (MIMVS) has been conducted for more than 25 years and has been shown to offer multiple benefits including better cosmetic results, enhanced post-operative recovery, improved patient satisfaction and most importantly, equivalent clinical outcomes with regards to quality and safety when compared to the standard sternotomy approach. MIMVS may be particularly beneficial in certain subgroups of patients, for example patients undergoing redo mitral valve surgery. In this article, we discuss patient selection criteria for MIMVS, the merits and drawbacks of MIMVS relative to conventional sternotomy approaches, and detail procedural aspects including anaesthetic management, intraoperative technique, and important considerations in myocardial protection and cardiopulmonary bypass (CPB). When considering developing a MIMVS programme, as for any new technique, a team approach to the introduction of the programme is essential. Although it is clear that patient selection is important, particularly early in a surgical programme, with experience complex repairs can be performed through a minimally invasive approach with excellent outcomes.
