Aortic valve disease is a prevalent disorder that affects approximately 2% of the general adult population. Surgical aortic valve replacement is the gold standard treatment for symptomatic patients. This treatment has demonstrably proven to be both safe and effective. Over the last few decades, in an attempt to reduce surgical trauma, different minimally invasive approaches for aortic valve replacement have been developed and are now being increasingly utilized. A narrative review of the literature was carried out to describe the surgical techniques for minimally invasive aortic valve surgery and report the results from different experienced centers. Minimally invasive aortic valve replacement is associated with low perioperative morbidity, mortality and a low conversion rate to full sternotomy. Long-term survival appears to be at least comparable to that reported for conventional full sternotomy. Minimally invasive aortic valve surgery, either with a partial upper sternotomy or a right anterior minithoracotomy provides early- and long-term benefits. Given these benefits, it may be considered the standard of care for isolated aortic valve disease.  相似文献

目的 对比研究传统正中开胸与胸骨上段小切口主动脉瓣置换手术的临床效果。方法 使用倾向评分匹配法,筛选了2016-2019年间在我院实施主动脉瓣手术的患者共62例,其中31例实施了微创主动脉瓣置换,31例采用胸骨正中开胸手术,比较两种手术方式的临床效果。结果 经过倾向评分匹配之后,两组患者术前基本资料差异无统计学意义。手术结果显示微创手术组患者手术中主动脉阻断时间以及体外循环时间均较正中开胸组患者延长(57.3±5.4min vs 55.2±6.8min;91.2±9.6min vs 90.7±7.2),然而两者之间差异无统计学意义(p值分别为0.177以及0.835)。然而,微创手术组患者术后24 h引流量明显少于正中开胸组(337.7±87.5ml vs 390.9±114.7ml),两者差异具有统计学意义(P=0.044)。此外,微创组患者伤口疼痛评分明显低于正中开胸组(3.52±1.15 vs 5.00±1.61),两者差异具有统计学意义(p<0.05)。结论 本研究结果显示,胸骨上段小切口主动脉瓣置换可以获得与传统正中开胸手术一样的效果,手术方式时安全有效的。  相似文献

BackgroundIn the context of the development of modern cardiac valve interventional methods (TAVI, TMVI, MitraClip), miniinvasivity in cardiac surgery is becoming increasingly important. An alternative approach to complete sternotomy in isolated aortic valve replacement (AVR) is access from anterior thoracotomy or upper ministernotomy. In CKTCH Brno, is performed an isolated aortic valve replacement (AVR) from the upper hemisternotomy (UHS) from 2013 onwards.MethodsBetween 2013 and 2016, isolated AVR was perfomed in our institution 666 patients. Full median sternotomy approach was used in 565 patients, minimally invasive approach (UHS) in 101 patients. In the ministernotomy group, classical biological or mechanical prosthesis was implanted in 55 patients; in 46 patients we used rapid deployment (sutureless) bioprosthesis Sorin Perceval S. In our study we compare the results of full sternotomy a hemisternotomy approach and also describe our surgical technique of minimally invasive aortic valve replacement.ResultsWe registered gradual increase in minimally invasive AVR between 2013 and 2016 (9 patients in 2013, 59 patients in 2016). The combined hospitalization and 30-day mortality was 0.53% (3 patients) in the full sternotomy group and 0.99% (1 patient) in the ministernotomy group. In the most risky patients, we indicated ministernotomy with implantation of rapid deployment bioprosthesis (Euroscore II. 3,0 vs. 1,6 in the group of patients with full sternotomy AVR). As published, we confirmed longer aortic cross clamp time (AoX) and lenght of extracorporal circulation (ECC) in the patients with ministernotomy and implantation of sutured aortic prosthesis in comparison with full sternotomy AVR. Conversely, shorter AoX time and ECC time was observed in patients with rapid deployment prosthesis implantation from ministernotomy. We also recorded smaller postoperative blood loss in patients with ministernotomy apporach. The other monitored parameter were comparable.ConclusionIn this study we describe our technique and results of minimally invasive aortic valve replacement in our institution. Based on our results, we evaluate this technique as safe and well reproducible.  相似文献

Aortic valve stenosis is the most common valve disease in the western world. Over the past few years the number of aortic valve re-placement (AVR) interventions has increased with outcomes that have been improved despite increasing age of patients and increasing burden of comorbidities. However, despite such excellent results and its well-established position, conventional AVR has undergone great development over the previous two decades. Such progress, by way of less invasive incisions and use of new technologies, including transcatheter aortic valve implantation and sutureless valve prostheses, is intended to reduce the traumatic impact of the surgical procedure, thus fulfilling lower risk patients’ expectations on the one hand, and extending the operability toward increasingly high-risk patients on the other. Sutureless and rapid deployment aortic valves are biological, pericardial prostheses that anchor within the aortic annulus with no more than three sutures. The sutureless prostheses, by avoiding the passage and the tying of the sutures, significantly reduce operative times and may improve outcomes. However, there is still a paucity of robust, evidence-based data on the role and performance of sutureless AVR. Therefore, strongest long-term data, randomized studies and registry data are required to adequately assess the durability and long-term outcomes of sutureless aortic valve replacement.  相似文献

BackgroundMinimally invasive aortic valve replacement (MiAVR) and transcatheter aortic valve implantation (TAVI) provide aortic valve replacement (AVR) by less invasive methods than conventional surgical AVR, by avoiding complete sternotomy. This study directly compares and analyses the available evidence for early outcomes between these two AVR methods.MethodsElectronic databases were searched from inception until August 2019 for studies comparing MiAVR to TAVI, according to predefined search criteria. Propensity-matched studies with sufficient data were included in a meta-analysis.ResultsEight studies with 9,744 patients were included in the quantitative analysis. Analysis of risk-matched patients showed no difference in early mortality (RR 0.76, 95% CI, 0.37–1.54, P=0.44). MiAVR had a signal towards lower rate of postoperative stroke, although this did not reach statistical significance (OR 0.42, 95% CI, 0.13–1.29, P=0.13). MiAVR had significantly lower rates of new pacemaker (PPM) requirement (OR 0.29, 95% CI, 0.16–0.52, P<0.0001) and postoperative aortic insufficiency (AI) or paravalvular leak (PVL) (OR 0.05, 95% CI, 0.01–0.20, P<0.0001) compared to TAVI, (OR 0.42, 95% CI, 0.13–1.29, P=0.13), while acute kidney injury (AKI) was higher in MiAVR compared to TAVI (11.1% vs. 5.2%, OR 2.28, 95% CI, 1.25–4.16, P=0.007).ConclusionsIn patients of equivalent surgical risk scores, MiAVR may be performed with lower rates of postoperative PPM requirement and AI/PVL, higher rates of AKI and no statistical difference in postoperative stroke or short-term mortality, compared to TAVI. Further prospective trials are needed to validate these results.  相似文献
