Abstract Background There is a paucity of data comparing the minimally invasive mitral valve repair (MiMVr) to the conventional approach in patients with degenerative disease. Our objective was to compare the outcomes of MiMVr to the traditional mitral valve repair through median sternotomy in patients with degenerative mitral valve disease. We conducted a retrospective study on 215 patients classified into two groups. Group 1 (n = 80) included those who had mitral valve repair through a right anterolateral video-assisted mini-thoracotomy, and group 2 (n = 135) was approached through a conventional median sternotomy. We compared the preoperative, operative, and postoperative data between groups. Both groups had echocardiographic follow-ups after 6 and 12 months. Results There was no difference in gender distribution between both groups, and patients who had median sternotomy were significantly older (median 37 (Q1-Q3, 29-44) vs. 54 (48-60) years; P < 0.001). Cardiopulmonary bypass (134.5 (130-138.5) vs. 99 (97-104) min; P < 0.001) and ischemic times (99 (95-105.5) vs. 78 (75-81) min; P < 0.001) were significantly shorter in patients who had median sternotomy. Patients with MiMVr had significantly lower blood loss (370 (315-390) vs. 550 (490-600) ml; P < 0.001) and ICU stay (5 (4.5-6) vs. 7 (7-8) days; P < 0.001). There was no difference between both groups regarding re-exploration for bleeding, postoperative stroke, wound infection, renal failure, and mortality. As regards postoperative echocardiography follow-up at 6 and 12 months after the operation, there were no significant changes in the mean mitral valve gradient within each group; however, the mean gradient was lower in the MiMVr group (3 (3-3.5) vs. 4 (3-5) mmHg; P < 0.001). There was no significant difference between both groups regarding mitral regurgitation severity during 6 and 12 months follow-up. Conclusion Minimally invasive mitral valve repair in patients with degenerative pathology could be an alternative to conventional mitral valve surgery with comparable short-term and long-term outcomes.

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.

Background and Objectives: Surgical atrial fibrillation (AF) ablation concomitant to minimally invasive mitral valve repair has been proven to offer improved short- and long-term sinus rhythm (SR) maintenance compared to mitral valve surgery only. The objective of the present study was to explore, by thorough echocardiographic assessment, long-term morphological and functional left atrial (LA) outcomes after this combined surgical procedure. Materials and Methods: From October 2006 to November 2015, 48 patients underwent minimally invasive mitral valve repair and concomitant surgical AF cryoablation. Results: After 3.8 ± 2.2 years, 30 (71.4%) of those completing the follow-up (n = 42, 87.5%) presented SR. During follow-up, four (9.5%) patients suffered from cerebrovascular accidents and two of these subjects had a long-standing persistent AF relapse and were in AF at the time of the event, while the other two were in SR. An echocardiographic study focused on LA characteristics was performed in 29 patients (69.0%). Atrial morphology and function (e.g., maximal LA volume indexed to body surface area and total LA emptying fraction derived from volumes) in patients with stable SR (60.6 ± 13.1 mL/mq and 25.1 ± 7.3%) were significantly better than in those with AF relapses (76.8 ± 16.2 mL/mq and 17.5 ± 7.4%; respectively, p = 0.008 and p = 0.015). At follow-up, patients who suffered from ischemic cerebral events had maximal LA volume indexed to body surface area 61 ± 17.8 mL/mq, with total LA emptying fraction derived from volumes 23.6 ± 13.7%; patients with strokes in SR showed very enlarged LA volume (>70 mL/mq). Conclusions: AF cryoablation concomitant with minimally invasive mitral valve repair provides a high rate of SR maintenance and this relates to improved long-term morphological and functional LA outcomes. Further prospective studies are needed to define the cut-off values determining an increase in the risk for thromboembolic complications in patients with restored stable SR.

Objective The assessment of the mitral valve apparatus (MVA) and its modifications during ischemic mitral regurgitation (IMR) is better performed by three-dimensional (3D) transesophageal echocardiography (TEE). The aim of our study was to carry out nonrestrictive mitral annuloplasty in addition to relocation of papillary muscles (PPMs) oriented by preoperative real-time 3D TEE through the mitral valve quantification dedicated software. Methods Since January 2008, a total of 70 patients with severe IMR were examined both before and after mitral valve repair. The mean (SD) coaptation depth and the mean (SD) tenting area were 1.4 (0.4) cm and 3.2 (0.5) cm2, respectively. Intraoperative 3D TEE was performed, followed by a 3D offline reconstruction of the MVA. A schematic MVA model was obtained, and a geometric model as a “truncated cone” was traced according to preoperative data. The expected truncated cone after annuloplasty was retraced. A conventional normal coaptation depth of approximately 6 mm was used to detect the new position of the PPMs tips. Results Perioperative offline reconstruction of the MVA and the respective truncated cone was feasible in all patients. The expected position of the PPMs tips, desirable to reach a normal tenting area with a coaptation depth of 6 mm or more, was obtained in all patients. After surgery, all parameters were calculated, and no statistically significant difference was found compared with the expected data. Conclusions Relocation of PPMs plus ring annuloplasty reduce mitral valve tenting and may improve mitral valve repair results in patients with severe IMR. This technique may be easily and precisely guided by preoperative offline 3D echocardiographic mitral valve reconstruction.

  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.

Objective Patients undergoing multiple valve surgery represent a high-risk group who could potentially benefit from a reduction of cross-clamp and cardiopulmonary bypass times because prolonged bypass and cross-clamp times are considered independent risk factors for increased morbidity and mortality after cardiac surgery. Methods Between July 2013 and November 2014, 16 patients underwent rapid deployment aortic valve replacement with the EDWARDS INTUITY valve system in the setting of concomitant mitral disease. Fifteen patients showed mitral regurgitation, whereas one patient had severe mitral stenosis. Fourteen patients received mitral valve repair and two patients received biological mitral valve replacement. Tricuspid valve repair was performed additionally in two patients. The mean ± SD age was 72.8 ± 8.4 years, and the mean ± SD logistic EuroSCORE II is 8.7% ± 3.4%. Results Within a 30-day perioperative period, no patient was lost (n = 0). The mean ± SD follow-up time was 11 ± 2 months. At 1 year, the overall survival was 81% (n = 13). A mean ± SD transaortic gradient of 10.7 ± 2.3 mm Hg and a mean ± SD effective orifice area of 1.7 ± 0.3 cm2 were measured echocardiographically. No higher-grade paravalvular leak (aortic insufficiency > 1+) occurred. Eight patients (61%) had no residual mitral regurgitation, four patients (30%) showed trivial regurgitation (1/4), and one patient (7.3%) had moderate mitral regurgitation (2/4). No interference of the subannular stent frame with the reconstructed valve or the biological mitral prosthesis was seen. Conclusions Rapid deployment aortic valve replacement with the EDWARDS INTUITY valve system in combined aortic and mitral valve surgery can be performed safely with reproducible results. One-year follow-up data of this small series shows encouraging results potentially justifying the extension of the indication for rapid deployment valves to patients with concomitant mitral disease. Especially elderly patients undergoing multiple valve surgery may benefit from a reduction of cardiopulmonary bypass and myocardial ischemic times.
