Background: Minimally invasive mitral valve surgery became an attractive option because of its cosmetic advantages over the conventional approach. The superiority of the minimally invasive approach regarding other aspects is still debatable. The aim of our study was to determine the potential benefits of minimally invasive mitral valve replacement with intraoperative video assistance over conventional surgery. Methods: This is a single-center prospective cohort study that included 60 patients with rheumatic heart disease who underwent mitral valve replacement. Patients were divided into two groups: group (A) included patients who had conventional sternotomy (n= 30), and group (B) included patients who had video-assisted minimally invasive mitral valve replacement (n= 30). Intraoperative and postoperative outcomes were compared between both groups. Results: Mortality occurred in one patient in the group (A). Cardiopulmonary bypass time was 118.93 ± 29.84 minutes vs. 64.73 ± 19.16 minutes in group B and A respectively (p< 0.001), and ischemic time was 102.27 ± 30.03 minutes vs. 53.67± 18.46 minutes in group B and A respectively (P < 0.001). Ventilation time was 2.77± 2.27 vs. 6.28 ± 4.48 hours in group B and A respectively (p< 0.001) and blood transfusion was 0.50 ± 0.63 vs. 2.83 ± 1.34 units in group B and A respectively (p< 0.001).  ICU stay was 1.73 ± 0.64 days in the group (B) vs. 4.47 ± 0.94 days in group A (p< 0.001). Postoperative bleeding was 353.33 ± 146.77 ml in the group (B) vs. 841.67 ± 302.03 ml in group A (p <0.001). No conversion to full sternotomy was reported in group B. In group (B), two cases (6.6%) required re-exploration for bleeding vs. four cases (13.2%) in group (A) (p=0.67). The hospital stay was 6.13 ± 1.59 days in the group (B) vs. 13.27 ± 7.62 days in group A (p< 0.001). Four cases (13.3%) developed mediastinitis in group A and in the group (B), there was one case of acute right lower limb embolic ischemia. Conclusion: Video-assisted minimally invasive mitral operations could be a safe alternative to conventional sternotomy with the potential of lesser morbidity and earlier hospital discharge.

Objective Video-assisted minimally invasive mitral valve surgery can be performed through different approaches. The aim of the study was to report our early results and compare the external transthoracic aortic clamping with the endoaortic balloon occlusion techniques according to our experience. Methods Between January 2000 and March 2010, 138 patients (103 women, aged 58.4 ± 10.2 years) underwent video-assisted mitral valve surgery through a right thoracotomy. Cardiopulmonary bypass was instituted by femoral arterial and bicaval cannulation with active venous drainage and normothermia; cardioplegic arrest achieved with intermittent blood cardioplegia. In group A (93 patients, 68 women, aged 58.8 ± 7.8 years, 72 MV replacement, 21 MV repair), aortic clamping was achieved using the external transthoracic aortic clamp. In group B (45 patients, 35 women, aged 58.1 ± 11.4 years, 33 MV replacement, 12 MV repair), aortic clamping was achieved with endoaortic balloon occlusion. Results Intraoperative procedure-associated problems were experienced in one patient (0.7%) in group A (one conversion to sternotomy for pleural adhesions and bad exposure). At a mean follow-up of 36 ± 18 months, 135 patients (97.8%) were in New York Heart Association class I to II, with satisfactory echocardiographic follow-up. In group A, two patients had noncardiac-related deaths. No perioperative deaths were observed in both groups. There were four (2.8%) transient ischemic attacks and one (0.7%) peripheral ischemic event (group A) during the early postoperative period. Mitral valve repair patients had a 5-year freedom from reoperation of 100% in both groups. There was no significant difference between the two groups regarding preoperative variables, such as age, sex, New York Heart Association class, and left ventricular ejection fraction (P ≥ 0.05). Postoperative levels of myocardial cytonecrosis enzymes (MB fraction, creatine kinase, and troponine I) as well as operative time, extracorporeal circulation, and aortic cross-clamping times or ventilation and intensive care unit times were not significantly different between the two groups (P ≥ 0.05). More microembolic events were observed in group A than in group B (total 143.4 ± 30.6 per patient vs 78.9 ± 28.6 per patient) by means of continuous automated intraoperative transcranial Doppler evaluations (P < 0.05) applied to part of population. Conclusions Both techniques proved safe and comparable with low risk of morbidity and mortality. Patients undergoing endoclamp technique resulted to be less subject to embolism.

Minimally invasive mitral valve surgery has become routine in many institutions. Disadvantages of this approach include prolonged aortic cross-clamp and cardiopulmonary bypass times. Mitral valve replacement with a continuous suture technique may reduce operative times. We present a case of a 51-year-old man suffering from severe rheumatic mitral disease to highlight our continuous suture technique for minimally invasive mitral valve replacement. We also report preliminary results from our series of 15 patients suffering various rheumatic mitral pathology treated with this technique.

Objective This study was carried out with the aim of presenting our experience with minimally invasive mitral surgery and compare the endoaortic clamp with the external aortic clamp (EAC) techniques. Methods Between December 2002 and May 2009, 139 patients (75 men, aged 63 ± 11 years) underwent video-assisted mitral valve surgery through right thoracotomy. Twelve (9%) patients were operated without clamping the aorta, 32 (23%) patients (group A) were operated on by using the endoaortic clamp, and 95 (68%) patients were operated on by using the EAC (group B). There was no significant difference between groups A and B regarding preoperative variables. Results Intraoperative procedure-associated problems were experienced in three group A patients (9.3%, two aortic dissections with conversion to sternotomy; one conversion due to bad exposure) and in two group B patients (2%, one conversion to sternotomy for bleeding and one for ascending aorta hematoma). At a mean follow-up of 32 months, 121 patients (97%) were in New York Heart Association class I–II, with satisfactory echocardiographic results. There was one in-hospital and six late deaths (three noncardiac, two cardiac, and one valve related). Five-year actuarial survival was 88% ± 8%. There were three reoperations, one early (<30 days) after complex mitral valve repair, with a 5-year freedom from reoperation of 97% ± 2%. Postoperative levels of myocardial cytonecrosis enzymes as well as the extracorporeal circulation time were significantly lower in group B patients (P < 0.05). Conclusions Intraoperative procedure-associated complications with endoclamping combined with an apparently better myocardial protection forced us to change our practice to the more simple and economic EAC technique.

Abstract Background There is now extension of minimally invasive techniques to involve concomitantly aortic and mitral valves through a single small incision. We share our experience in such surgeries through upper partial sternotomy with approaching the mitral valve through the dome of the left atrium. Methods Two matched groups of cases receiving concomitant aortic and mitral valve surgeries are compared regarding the surgical outcomes: the minimally invasive group (group A) including 72 patients and the conventional group (group B) including 78 patients. Results The mean age was 52 ± 8 years in group A and 53 ± 7 years in group B. Males represented (42%) in group A and (49%) in group B. The mean mechanical ventilation time was significantly shorter in group A (4.3 ± 1.2 hours) than in group B (6.1 ± 0.8 hours) with a p-value of 0.001. In addition, the amount of chest tube drainage and the need for blood transfusion units were significantly less in group A (250 ± 160 cm3 and 1.3 ± 0.8 units, respectively) when compared with group B (320 ± 180 cm3 and 1.8 ± 0.9 units, respectively) with p-values of 0.013 and 0.005, respectively. Over a follow-up period of 3.2 ± 1.1 years, one mortality occurred in each group with no significant difference (p-value = 0.512). Conclusion Combined aortic and mitral valve surgery through upper partial sternotomy with approaching the mitral valve through the dome of the left atrium is safe and effective with the advantages of less postoperative blood loss, need for blood transfusion, and mechanical ventilation time compared with conventional aortic and mitral valve surgery.

Introduction: When implementing a minimally invasive cardiac surgery program, increased surgical times may serve as a deterrent. Results demonstrating parity in operative times between minimally invasive (MIMVR) and conventional mitral valve replacement/repair (CMVR) have been limited to high-volume centers. The purpose of this study was to examine operative efficiency for MIMVR in a low-volume center. Methods: All patients having undergone non-emergent, isolated MIMVR or CMVR at the New Brunswick Heart Centre from 2011-2017 were considered. Detailed peri-operative data, including cross clamp (XC), cardiopulmonary bypass (CPB), skin-to-skin (SS) and total operative (TO) times, were collected. Patients were assigned to one of 3 eras: 2011-2013, 2014-2015, 2016-2017. Unadjusted comparisons were made between MIMVR and CMVR over the entire study period and within each era. Results: A total of 168 patients were included (MIMVR: 64; CMVR: 104). There was an increase in the number of MIMVR cases over time (2011-2013: 19; 2014-2015: 17; 2016-2017: 28). Patients undergoing MIMVR were less likely to be ≥70years (29.7% vs. 47.1%, p=0.04) and to have had NYHA-IV symptoms (17.2% vs. 41.3%, p=0.002), previous cardiac surgery (4.7% vs. 23.1%, p=0.003) or urgent presentation (12.5% vs. 35.6%, p=0.002). Intra-operatively, MIMVR patients were more likely to have undergone a mitral valve repair (65.1% vs. 29.1%, p<0.0001). No differences were noted in rates of in-hospital mortality (0.0% vs. 5.1%, p=0.29). Median operative times were uniformly longer among MIMVR patients between 2011-2013. However, in 2014-2015 and 2016-2017, these times improved to the point where no significant differences in operative efficiency were noted (Figure). Conclusions: Improved operative efficiency may be safely achieved for MIMVR in a low-volume center. The results of this study should encourage low-volume centers to adopt a minimally invasive approach to isolated mitral valve surgery.

Abstract OBJECTIVES Subannular repair techniques in addition to undersized ring annuloplasty have been developed to address high mitral regurgitation (MR) recurrence rates after mitral valve repair in type IIIb MR. We compared the results of annuloplasty with simultaneous standardized subannular repair versus isolated annuloplasty, focusing on the periprocedural outcomes of minimally invasive procedures. METHODS A consecutive series of 108 patients with type IIIb functional MR with severe signs of bileaflet tethering underwent an annuloplasty + subannular repair (group A; n = 60) versus isolated annuloplasty (group B; n = 48). The primary end point of this prospective, parallel cohort study was death or recurrent MR >2, 1 year postoperatively. The secondary end points were survival and clinical outcomes, with special regard for the minimally invasively treated subgroups. RESULTS Duration of surgery, cardiopulmonary bypass time and aortic cross-clamp time were comparable between both study groups. Procedural outcomes as well as echocardiographic outcome parameters were similar and independent of access (fully endoscopic versus full sternotomy). At the 12-month follow-up, death or MR >2 occurred in 3.3% (2/60) of patients in group A vs in 20.8% (10/48) of patients in group B (P = 0.037). The overall mortality rate during the follow-up period was 1.7% (1/60) in group A vs 12.5% (6/48) in group B (P = 0.041). CONCLUSIONS Standardized realignment of papillary muscles is feasible and reproducible via a minimally invasive approach, resulting in excellent periprocedural outcomes, and has a clear potential to significantly decrease MR recurrence and improve 1-year outcomes compared to isolated annuloplasty.

Objective Obesity is highly prevalent in modern patient populations. Several studies have published conflicting outcomes after minimally invasive surgery with regard to morbidity and mortality. Some instances consider obesity as a relative contraindication for this approach because of inadequate exposure of the surgical field. Our aim was to investigate the outcomes of minimally invasive mitral valve surgery through a right lateral minithoracotomy in patients with a body mass index (BMI) of 30 kg/m2 or greater. Methods We conducted a retrospective database review between January 1, 2009, and December 31, 2011. Preoperative, intraoperative, postoperative, and follow-up data of 225 consecutive patients were collected. Results The patients were stratified according to their BMI: 108 had a normal weight with a BMI of lower than 25 kg/m2 (18–24), 90 were overweight with a BMI of 25 to 29 kg/m2, and 27 were obese with a BMI of 30 kg/m2 (30–41) or greater. Statistical analysis showed significantly longer ventilation times in the obese group, whereas all other variables were similar. Survival, major adverse cardiac and cerebrovascular event-free survival, valve competency, and freedom from reoperation were also comparable. Conclusions Our data suggest that obesity should not deter a surgeon from selecting a minimally invasive approach. Despite longer postoperative ventilation times, a BMI of 30 kg/m2 or greater does not influence short- and medium-term outcome. Obese patients may even benefit from this approach because it avoids the need for sternotomy and therefore reduces the risk for sternal wound infection.
