Objective To date, a direct comparison of minimally invasive mitral valve repair or replacement (mini-MVR) versus robotic MVR is lacking; therefore, the purpose of this study was to address this deficit and compare mini-MVR with robotic MVR from a cost-benefit perspective. Methods From a total of 759 literature citations, 21 studies were included for statistical comparisons of benefit outcomes, whereas 3 studies and our institutional experience were used to compare costs. Results The total cost per case exceeding that of conventional MVR is approximately $2063.90 for robotic MVR and $271 for mini-MVR. Mean 30-day mortality rates for mini-MVR and robotic MVR groups were 1.24% and 0.55%, respectively [106/8548 vs 6/1089; odds ratio (OR), 2.27; P = 0.052]. The conversion rate to conventional MVR was 0.77% in mini-MVR and 1.83% in robotic MVR (35/5092 vs 22/1046; OR, 0.32; P < 0.001). The rate of neurologic events was 1.32% in mini-MVR and 2.37% in robotic MVR (109/8257 vs 20/845; OR, 0.55; P = 0.02). Postoperative atrial fibrillation was seen in 11.42% of mini-MVR patients and in 19.67% of robotic MVR patients (371/3249 vs 203/1032; OR, 0.53, P < 0.001). Mean cardiopulmonary bypass time was longer in mini-MVR (137.4 vs 130.4 minutes), whereas cross-clamp time was shorter (82.2 vs 96.7 minutes). Conclusions Our comparative analysis provides insights into the clinical benefits versus variable costs relationship related to mini-MVR and robotic MVR.

Abstract Objectives Barlow´s disease represents a wide spectrum of mitral valve pathologies associated with regurgitation (MR), excess leaflet tissue, and prolapse. Repair strategies range from complex repairs with annuloplasty plus neochords through resection to annuloplasty-only. The latter requires symmetric prolapse patterns and central regurgitant jets. We aimed to assess repair success and durability, survival, and intraoperative outcomes with symmetric and asymmetric Barlow’s disease. Methods Between 09/10 and 03/20, 103 patients (of 1939 with mitral valve surgery) presented with Barlow´s disease. All received surgery through mini-thoracotomy with annuloplasty plus neochords (n = 71) or annuloplasty-only (n = 31). One valve was replaced for endocarditis (repair rate: 99%). Results Annuloplasty-only patients were older (64 ± 16 vs. 55 ± 11 years, p = 0.008) and presented with higher risk (EuroSCORE II: 4.2 ± 4.9 vs. 1.6 ± 1.7, p = 0.007). Annuloplasty-only patients had shorter cross-clamp times (53 ± 18 min vs. 76 ± 23 min, p < 0.001) and received more tricuspid annuloplasty (15.5% vs. 48.4%, p < 0.001). Operating times were similar (170 ± 41 min vs. 164 ± 35, p = 0.455). In three patients, annuloplasty-only caused intraoperative systolic anterior motion (SAM), which was fully resolved by neochords to the posterior leaflet. There were no conversions to sternotomy or deaths at 30-days. Three patients required reoperation for recurrent MR (at 25 days, 2.8 and 7.8 years). At the latest follow-up, there was no MR in 81.4%, mild in 14.7%, and moderate in 2.9%. Three patients died due to non-cardiac reasons. Surviving patients report the absence of relevant symptoms. Conclusions Minimally-invasive Barlow’s repair is safe with good durability. Annuloplasty-only may be a simple solution for complex but symmetric pathologies. However, it may carry an increased risk of intraoperative SAM.

We conducted a retrospective comparative analysis of 75 patients undergoing video-assisted mitral valve repair with right minithoracotomy over a period from November 2011 to August 2013. The control group comprised 71 patients operated on mitral valve by using median sternotomy during the same period. Median (25th; 75th) times of cardiopulmonary bypass and aortic cross-clamping were significantly longer in the minimally invasive group (180 [139; 224] and 111 [87; 145] min, respectively) as compared to the controls (84 [69; 117] and 62 [49; 81 ] min, respectively), p<0.01. Fatal outcome occurred in 2 (2.7%) cases in the minimally invasive group versus none in the controls. In both cases death resulted from intraoperative aortic dissection. While ventilation time and intensive care unit stay were comparable across the groups, postoperative respiratory failure occurred in 6 (8%) cases in the minimally invasive group versus none in the controls (p<0.05). No other significant differences in the postoperative course were observed between the groups. The results of the present study are generally consistent with the world's tendencies. On the other hand, complication rates observed in the minimally invasive group present a considerable economic burden and require substantial human resources in the postoperative period.

Telehealth is an emerging area of medical research. Its translation from conception, to research and into practice requires tailored research and economic evaluation methods. Due to their nature telehealth interventions exhibit a number of extra-clinical benefits that are relevant when valuing their costs and outcomes. By incorporating methods to measure societal values such as patient preference and willingness-to-pay, a more holistic value can be placed on the extra-clinical outcomes associated with telehealth and evaluations can represent new interventions more effectively. Cost-benefit analysis is a method by which relevant costs and outcomes in telehealth can be succinctly valued and compared. When health economic methods are conducted using holistic approaches such as cost-benefit analysis they can facilitate the translation of telehealth research into policy and practice.

Abstract OBJECTIVES Mitral valve repair is the preferred method used to address mitral valve regurgitation, whereas transcatheter mitral valve repair is recommended for high-risk patients. We evaluated the risk-predictive value of the age-adjusted Charlson comorbidity index (aa-CCI) in the setting of minimally invasive mitral valve surgery. METHODS The perioperative course and 1-year follow-up of 537 patients who underwent isolated or combined minimally invasive mitral valve surgery were evaluated for 1-year mortality as the primary end point and other adverse events. The predictive values of the EuroSCORE II and STS score were compared to that of the aa-CCI by a comparative analysis of receiver operating characteristic curves. Restricted cubic splines were applied to find optimal aa-CCI cut-off values for the increased likelihood of experiencing the predefined adverse end points. Consequently, the perioperative course and postoperative outcome of the aa-CCI ≥8 patients and the remainder of the sample were analysed. RESULTS The predictive value of the aa-CCI does not significantly differ from those of the EuroSCORE II or STS score. Patients with an aa-CCI ≥8 were identified as a subgroup with a significant increase of mortality and other adverse events. CONCLUSIONS The aa-CCI displays a suitable predictive ability for patients undergoing minimally invasive mitral valve surgery. In particular, multimorbid or frail patients may benefit from the extension of the objectively assessed parameters, in addition to the STS score or EuroSCORE II. Patients with an aa-CCI ≥8 have a very high surgical risk and should receive very careful attention.

  Background. Minimally invasive mitral valve surgery provides many advantages for patients. The aim. To investigate and represent our own experience in minimally invasive mitral valve surgery, and to describe the operative technique. Materials and methods. The study was included 100 consecutive patients who underwent a minimally invasive mitral valve repair or replacement through the right lateral minithoracotomy from June 2017 to December 2019. Results. Mitral valve repair was performed in 87 patients (87%), and 13 patients (13%) were required mitral valve replacement. In 24 patients (24%), concomitant procedures were performed: tricuspid valve repair, atrial septal defect repair and left atrial myxomectomy. Ring anuloplasty was performed in all patients who underwent mitral valve repair. Additional methods of correction were used in accordance to the lesion anatomy: neochords implantation, cleft and leaflet perforation closure, leaflet resection, Alfieri (edge-to-edge) stitch, posterior leaflet plication. There was no in-hospital and 30-day mortality. Post-operative strokes were not reported. No wound complications were observed in the femoral cannulation area. The total length of stay in a hospital was 6 ± 1.46 (3–9) days. There were no cases of mitral valve insufficiency greater more than mild degree after mitral valve repair at the time of discharge. Conclusions. Minimally invasive mitral valve surgery can be performed as a routine standard approach, provides safe and effective correction of the mitral valve defects, allows excellent results of mitral valve repair and replacement in various abnormalities. Minimally invasive approach enables to perform a large number of reconstructive valve techniques and perform simultaneous correction of atrial septal defects, tricuspid valve repair and atrial neoplasm removal.

Abstract Background: Malaria is an insect-borne infectious disease that spreads through bites from infected Anopheles mosquitos. The disease seriously endangers human health and economic development. The study focuses on Fujian Province, China, which entered the final stage of malaria elimination stage in 2005. In order to understand the costs and benefits of malaria monitoring measures during the elimination stage, the health economics of the monitoring measures should be examined. Methods: Data on the number of cases during the malaria elimination stage (2005–2019) in Fujian Province were collected and sorted. The basic economic data were obtained from the Fujian Statistical Yearbook. Based on the fundamental theories in health economics, a cost-benefit analysis was conducted based on the data. Specifically, the cost of monitoring measures during the malaria elimination stage was calculated by economic cost and compared to the benefits, which were quantified based on economic and social benefits of the monitoring measures.Results: The total cost of monitoring measures in the malaria elimination stage was estimated at 607,878,783.36 yuan (USD 87,534,544.80). The components of the total cost were: case detection and treatment, which accounted for 66.62% of costs, health education with 13.31%, epidemic monitoring, 10.05%, supervision and assessment, 5.15%, and training and meetings took 4.87%. The total benefit of the monitoring measures in the malaria elimination stage was valued at about 116,123,417,911.81 yuan (USD 16,721,772,179.30). Direct economic benefit accounted for 22.61% of the total, while the social benefit was 77.39%. The cost-benefit analysis of the malaria elimination stage showed that the net benefit of monitoring measures was about 115,515,539,128.45 yuan (USD 16,634,237,634.50) and the benefit-cost ratio was 191.03. The monitoring cost for residents was 1.08 yuan (USD 0.16) per capita, and the benefit for residents was 206.12 yuan (USD 29.68) per capita. Conclusions: The monitoring measures conducted in the malaria elimination stage are a highly cost-effective intervention for reducing the negative impact of malaria in Fujian Province. Over the past 15 years, malaria control work has achieved excellent economic and social benefits in Fujian and the work should continue. The framework and results of this study conform to the principles of health economics and have a reference value for current malaria monitoring practices.
